June in the garden

It would be hard to summarise what we have been up to in the vegetable garden lately, so I took my crappy phone over with me to take some photos to show what we have been up to…

The broadbeans are doing really well. These I sowed as seed last autumn and we have already harvested a large amount, some small pods, some big that have been shelled.

This week we have harvested: broadbeans, parsley, Swiss chard (or perpetual leaf spinach), rocket, lettuce, radishes, cucumber, garlic, tree cabbage and wild strawberries.

Rocket

After trying sooooo many times to grow spinach and carrots this year, I have started again with fresh seeds – fingers crossed it will work!

I also planted out my pumpkins today, the last crop to go outside. Now I just have to get a serious move on with my sweet potatoes and some of my tomatoes need larger pots too…

‘Charlotte’ Potatoes 

Potatoes are looking as lovely as ever. I think I should just stick to potatoes. They seem to be all I can manage!

Onions

We have had really bad slug and snail damage this year – even the onions have suffered, which is very unusual. Protection has been put in place to save our babies at the cost of bug life 😦  There are only so many crops you can lose before you have to take action.

Runner Beans

Our lovely runner beans are growing every day. The ones in the front row of this picture are the ones that we planted two years ago and left the roots in the ground. We covered them up to protect them from the frost over winter and now they have grown beautifully yet again. There are another two trenches of beans in the background, and another couple in the garden. Got to love beans.

Grown from seed sweetcorn. Our neighbour kindly gave us another couple of batches from her own garden too. One might produce…?

Cheeky self-seeding orach growing among the broadbeans

Other than that, it has been weeding and feeding non-stop here. Working on clay soil at another garden has made me realise how hungry our plants must be on sandy soil. Compared to the other garden, ours need constant watering and manuring to keep them fit and strong.

Pumpkin

A pumpkin is a cultivar of a squash plant, most commonly of Cucurbita pep, that is round, with smooth, slightly ribbed skin, and deep yellow to orange colouration. The thick shell contains seeds and pulp. Some exceptionally large ones are derived from Cucurbita maxima. In NZ and Australia, the term pumpkin generally refers to the broader category called winter squash elsewhere.

img_3764

Native to North America pumpkins are widely grown for commercial use and are used both in food and recreation. Pumpkin pie is a traditional part of Thanksgiving meals in the US although commercially canned pumpkin puree and pumpkin pie fillings are usually made from different kinds of winter squash than the pumpkins frequently carved as for decoration at Halloween. Pumpkins, like other squash, are thought to have originated in North America. The oldest evidence of pumpkin-related seeds dating between 7000 and 5500 BC was found in Mexico. Since some squash share the same botanical classifications as pumpkins, the names are frequently used interchangeably. One often-used botanical classification relies on the characteristics of the stems: pumpkin stems are more rigid, prickly, and angular (with an approximate five-degree angle) than squash stems, which are generally softer, more rounded and more flared where joined to the fruit. Pumpkin fruits are a type of botanical berry known as a pepo. The word pumpkin originates from the word pepon which is Greek for “large melon”, something round and large. The French adapted this word to pompon, which the British changed to pumpion and to the later American colonists became known as pumpkin. Traditional C. pepo pumpkins generally weigh between 3 and 8kg (6 and 18 lb), though the largest cultivars, C. maxima, regularly reach weights of over 34 kg (75 lb). The color of pumpkins derives from orange carotenoid pigments, including beta-carotene found in carrots, provitamin B compounds converted to vitamin A in the body.

Pumpkins are a warm-weather crop that are usually planted in early July. The specific conditions necessary for growing pumpkins require that soil temperatures 8cm (3 in) deep are at least 15.5C (60F) and soil that holds water well. Pumpkin crops suffer if there is a lack of water or because of cold temperatures and sandy soil with poor water retention or poorly drained soils that become waterlogged after heavy rain. Pumpkins are, however, rather hardy, and even if many leaves and portions of the vine are removed or damaged, the plant can very quickly re-grow secondary vines to replace what was removed. The thing I most fear for our pumpkins is powdery mildew – Powdery Mildew

IMG_1401
A courgette with powdery mildew – the white spots that grow on the leaves before the plant shrivels and dies.

Pumpkins produce both a male and female flower. Bees play a significant role in the fertilisation of the flowers. Pumpkins have historically been pollinated by the native squash bee, Peponapis pruinosa, but this bee has declined, probably at least in part to pesticide sensitivity. Today most commercial plantings are pollinated by honeybees. One hive per acre (4,000 m2 per hive, or 5 hives per 2 hectares) is recommended by the US Dept. of Agriculture. If there are inadequate bees for pollination, gardeners often have to hand pollinate – inadequately pollinated pumpkins usually start growing but abort before full development.

To grow pumpkins, plant one seed in a tall yoghurt container filled with good compost, puncture a hole in the bottom of the pot to allow water to drain through, in April. Plant 1.5cm, 1/2 inch, deep (deep as your thumb) and firm the soil over the top. Keep well watered and put on a warm, sunny windowsill in your house. Take it off the windowsill at night to keep it warm. Transplant outdoors in May or when the frosts are over, spacing 1.2m (4’) apart. Keep moist and well fed – I feed mine lots of manure throughout the season because of my sandy soil that leaks away the nutrients – pumpkins are hungry plants. To prevent the fruit from rotting, gently lift from the ground and place a brick or large stone underneath them. Careful not to damage the stem. Harvest once they are turning orange all over, September – November and before the first frosts. The most obvious clue is to look at the stem as if it has died off and turned hard you know that the fruits are ready. Other ways of telling that the moment of truth has arrived is to slap the fruit (it should sound hollow) and to push your thumbnail into the skin, which should dent but not puncture. Cut the stalks a good 4 inches from where it joins the fruit. Wash the fruit with soapy water containing one part of chlorine bleach to ten parts of water to remove the soil and kill the pathogens on the surface of the fruit. Make sure the fruits are well dried. Then you need to cure it. Curing involves the hardening the skins to protect the flesh inside from deterioration. Do it properly and you can expect fruits to stay in top form for at least three months, comfortably taking you to the first harvests of next spring.  Remove the fruits to a greenhouse or as sunny a windowsill as you can find having first brushed off any dirt. Allow your fruits to sunbathe and develop a tan! This should take about two weeks for the top of the fruit then once carefully flipped over, another two weeks for the bottom. Pumpkins and winter squash prefer a well-ventilated, dry place. Keep the fruits raised up off hard surfaces on racks or wire mesh with a thick layer of newspaper or straw. Keeping them off the ground will allow air to circulate around the fruits while the extra padding will prevent the skin softening and becoming vulnerable to infection.

The best pumpkin variety I’ve tried so far are ‘Racer’.

The practice of carving pumpkins for Halloween originated from an Irish myth about a man named Stingy Jack. The turnip has traditionally been used in Ireland and Scotland at Halloween, but immigrants to North America used the native pumpkin, which are both readily available and much larger, making them easier to carve than turnips. Not until 1837, does jack-o’-lantern appear as a term for a carved vegetable lantern and the carved pumpkin lantern association with Halloween is first recorded in 1866. In the United States, the carved pumpkin was first associated with the harvest season in general, long before it became an emblem of Halloween. In 1900, an article on Thanksgiving entertaining recommended a lit jack-o’-lantern as part of the festivities to encourage families to join together to make their own jack-o’-lanterns. Association of pumpkins with harvest time and pumpkin pie at Thanksgiving reinforce its iconic role. Pumpkin chunking is a competitive activity in which teams build various mechanical devices designed to throw a pumpkin as far as possible. Catapults and air cannons are some of the common mechanisms. Some pumpkin chunkers breed and grow special varieties of pumpkin under specialized conditions to improve the pumpkin’s chances of surviving a throw.

Pumpkin seeds, leaves, and juices all pack a nutritional punch. Pumpkin has a range of health benefits, including being one of the best-known sources of beta-carotene and are a good source of fibre -one cup of cooked pumpkin is 2.7kg of fibre. Pumpkins have been found to reduce blood pressure, reduce risk of cancer, combats diabetes and supports your immune system.

Here are some yummy pumpkin recipes and ideas to get you started:

You can simply roast them at 180C in the oven covered in olive oil for 45 minutes. You can use them in soups, stews. Grate them up and add them to any casserole or bolognese, stir fry etc. Make pumpkin pie, try inventing a new dip…

Sweetcorn

IMG_1552.jpg

Sweetcorn (Zea mays convar. saccharata var. rugosa), is a variety of maize with a high sugar content. It is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Unlike field corn varieties, which are harvested when the kernels are dry and mature (dent stage), sweetcorn is picked when immature (milk stage) and prepared and eaten as a vegetable, rather than a grain.

IMG_1655.jpg
Ready for pollinating

The cultivation of corn as maize began over 8000 years ago in Mesoamerica, a geographical area which includes central and southern Mexico, and Central America. Corn was first domesticated from teosinte (Zea mexicana), an annual grass native to this region. Wild teosinte mostly has value as a fodder plant, as it provides very little edible seeds. The first archaeological evidence of domesticated corn comes from the San Marcos cave in Tehuacan and the Guilá Naquitz cave in the state of Oaxaca, Mexico. The corn in San Marcos cave is dated to over 5,000 years ago. The cobs from the Guilá Naquitz cave were dated to over 6200 years old. Humans first domesticated corn by selecting the teosinte plants that had the largest amount of edible seeds until they eventually provided a substantial food source. In the process, humans have transformed corn into a plant that can no longer self-sow and modern corn now requires breaking the tightly bound cob to remove the seeds. Wild teosinte, however, is very fragile and the seeds easily fall off and grow new plants. Without human interaction modern corn would probably cease to exist.

IMG_1657.jpg
Tassels – this is where the grainy seeds need to fall to pollinate

The Iroquois, Native American tribes, gave the first recorded sweetcorn, called ‘Papoon’, to European settlers in 1779. It soon became a popular food in southern and central regions of the US. Open pollinated cultivators of white sweetcorn started to become widely available in the US in the 19th century. Two of the most enduring cultivars, still available today, are ‘Country Gentleman’and ‘Stowell’s Evergreen’. Sweetcorn production in the 20th century was influenced by the following key developments: hybridisation allowed for more uniform maturity, improved quality and disease resistance, and, in 1933 ‘Golden Cross Bantam’ was released. It is significant for being the first successful single-cross hybrid and the first specifically developed for disease resistance. Open pollinated (non-hybrid) corn has largely been replaced in the commercial market by sweeter, earlier hybrids, which also have the advantage of maintaining their sweet flavour longer.

IMG_1658.jpg
Grainy seed tops

There are different varieties of sweetcorn – old types and supersweet types as well as mini types. Choose only one variety or they cross pollinate and make a gross hybrid that you don’t want.

I’ve only grown ‘Swift F1’ – and it is brilliant.

Sow in pots as early as March or as late as May, indoors. I use tall yoghurt pots filled with compost. Keep them in warm temperatures to grow with plenty of water and sunlight. Plant them out when they are about 7cm tall and the frosts have most definitely passed, May or June, 30cm apart. Sweetcorn is wind pollinated so plant them in clustered groups (picture the fields of corn grown on the country farms around Britain, all packed together) rather than rows to maximise pollination. Plant in soil that has been prepared with compost and well-rotted manure. I keep feeding mine with Blood, Fish and Bone and well-rotted manure or a liquid feed throughout the season to encourage the growth of the corn itself. Keep well watered in any dry periods. To increase pollination, try brushing the dusty pollen off the tops of the sweetcorn onto the tassels – this is where the corn will grow if pollinated. The tassels on the plant will turn yellow if fertilised. The cobs are ready when the tassels turn dark brown, July-September. To check, peel back the green covering and pierce a thumbnail into one of the niblets – if the liquid that is released is milky, your sweetcorn is ready. If it is clear, leave if a little longer but check daily.

IMG_3545.JPG
Undeveloped corn on the cobs – I’ve never taken a picture when they actually looked like ones bought in the shop, only the odd looking ones here 😦

The aim is to harvest sweetcorn in its prime. The sugars convert to starches rapidly once the corn leaves the plant and the taste will only become poorer as time goes on – same for asparagus and peas. Have the pan of boiling water ready, pick and plunge your cobs straight in. Or freeze them immediately (it stops the sugar/starch conversion process).

IMG_3216.jpg
Tassels dying back – the corn is forming

The only problems with sweetcorn are they take up space, they might not pollinate as reliably as insect pollinated plants (it will be very weather dependent) and if you have a problem with mice you might need to consider some protection.

For companion planting, consider the ‘Three Sisters’ from the USA: sweetcorn, beans and pumpkins. My first year I grew pumpkins with the sweetcorn. Last year I grew lettuces and radishes between them. This year I am considering a variety of cucurbits because they both enjoy the sunny conditions – courgettes, pumpkins and squashes, that is.

To cook and eat sweetcorn: it can of course become ‘corn on the cob’ – boil, grill or barbecue and slather in butter and hand them out for people to chew off the little gold nuggets. To remove the kernels from the cob, boil for a few minutes in boiling water (don’t add salt, it hardens the kernels), get a sharp knife and scrape them off into a bowl and serve. They are lovely with any meal that includes boiled veg, salads, mixed with tuna and mayonnaise is a traditional one, delicious with peas and baked potatoes mashed with butter, they are a traditional vegetarian option for the barbecue – try spreading some chill sauce over the top after grilling for a spicy taste. I think they are delicious also in a stir fry and a great addition to Egg Drop Soup with Vegetable Stock. I offer you the other recipe that springs to mind when I picture sweetcorn – my mum’s sweetcorn fritters.

IMG_2724.JPG

Sweetcorn Fritters 

(Makes enough to serve 4 people a few each)

-260g fresh sweetcorn (if you are using bought canned, use a 325g tin) -100g gram flour (or plain flour, gram flour is made from chickpeas and adds extra protein) -3 eggs -120g cheddar cheese -80g Gruye cheese -50g grated courgette or 1tbsp milk, optional -Small knob of butter, for frying

  1. Scald the fresh sweetcorn so the corn comes off the cob easier. If you are using tinned sweetcorn, drain it and set to one side.
  2. In a large bowl, sieve in the flour. Make a well in the middle. Add the eggs and stir them into the flour to make a batter.
  3. Grate the cheese and mix it in. Ass the corn and either a little courgette or milk to make it a dropping consistency, only a little though.
  4. Warm up the butter in a frying pan and drop spoonfuls of the batter into it – four per frying pan. Fry on one side and then flip over, using a spatula, and fry on the other side. Press down on the batter – when it is no longer leaking liquid, it is cooked through. Place on a plate lined with kitchen roll. Serve with vegetables, salad, rice, potatoes, dips… ketchup?

What to do with left over pumpkin?

IMG_4003.JPG

For anyone who is debating throwing out their pumpkin after Halloween – stop!

IMG_3950.JPG

Start by cutting it up into chunks.

Any seeds you have saved from the inside, pat them dry and follow this recipe:

Pumpkin Seed Crisps – smell and taste like popcorn

– Seeds from a pumpkin – Salt and pepper – Olive oil

  1. Preheat the oven to 180C.
  2. Scrape out the seeds from the inside of a pumpkin and pat dry with kitchen roll. Place them on a pan and sprinkle salt and pepper generously over the top along with a little olive oil.
  3. Bake in the oven for 15 minutes or until golden brown.

IMG_4007.JPG

For the pumpkin flesh, put the chunks on large roasting trays and drizzle with olive oil. Pop them in the oven at 180C and roast for about 40 minutes or until they are cooked.

Eat them like this alongside other veggies or dishes or use these roasted slices for another recipe…

Pumpkin Curry

(Serves 4)

– 1 onion, finely sliced – 1 tsp ghee or oil for frying – 1 tbsp mustard seeds – 1tbsp nigella seeds – 1 tbsp fenegreek seeds – 1 handful curry leaves – 1 tsp cumin – 1 tsp ground coriander – 1 1/2 tsp ground turmeric – 1 1/4  tsp ground garam masala – 500g roasted pumpkin – 1 large garlic clove, diced  Rice, chapatti, popadom, naan or a mixture, to serve – Freshly cut coriander and parsley, to serve

  1. Oil a large frying pan. Peel and slice the onion into thin strips and place in the pan. Heat high for a few minutes before turning down to simmer, stirring the onion. Let the onion simmer to a golden brown before adding the mustard seeds, nigella seeds, fenegreek seeds and curry leaves, stirring in the ingredients to combine. Allow the contents of the pan to simmer for a few minutes to absorb the flavours.
  2. Add the other spices: cumin, ground coriander, turmeric and garam masala, quickly followed by the pumpkin.
  3. Add the diced garlic clove, stir in.
  4. Serve hot on its own, with rice, an Indian bread, chutneys and freshly picked herbs from your garden, like parsley or coriander, torn and sprinkled over the top.

IMG_3989.JPG

Pumpkin Dahl 

(Serves 4)

– 1 onion, finely sliced – 1 tsp ghee or oil for frying – 1 tbsp mustard seeds – 1tbsp nigella seeds – 1 tbsp fenegreek seeds – 1 handful curry leaves – 1 tsp cumin – 1 tsp ground coriander – 1 1/2 tsp ground turmeric – 1 1/4  tsp ground garam masala – 300-400g roasted and food-processed/ raw, grated pumpkin – 1 large garlic clove, diced – 250g red split lentils -Boiling water from the kettle – Rice, chapatti, popadom, naan or a mixture, to serve – Freshly cut coriander and parsley, to serve

  1. Oil a large frying pan. Peel and slice the onion into thin strips and place in the pan. Heat high for a few minutes before turning down to simmer, stirring the onion. Let the onion simmer to a golden brown before adding the mustard seeds, nigella seeds, fenegreek seeds and curry leaves, stirring in the ingredients to combine. Allow the contents of the pan to simmer for a few minutes to absorb the flavours.
  2. Add the other spices: cumin, ground coriander, turmeric and garam masala, quickly followed by the finely grated pumpkin. Place a pan lid over the top of the frying pan and leave until the pumpkin is slightly cooked. Lift the lid occasionally to stir to encourage the ‘sweating’ of the vegetables.
  3. Add the diced garlic clove, stir in.
  4. Meanwhile, boil a kettle of water. Put the red lentils into a glass or other microwave dish, large enough to hold all of the contents of the Dahl. Scrape the contents of the frying pan into the dish along with the lentils, followed by the boiling water, enough so that it is covering the ingredients. Stir to combine.
  5. Place a lid over the top of the Dahl and microwave for 15 minutes before checking and stirring. If the lentils have absorbed all of the liquid, it is ready. It will probably need around half an hour before this happens. If the lentils look too dry, add a dash of more boiling water.
  6. Serve hot on its own, with rice, an Indian bread, chutneys and freshly picked herbs from your garden, like parsley or coriander, torn and sprinkled over the top.

Pumpkin Cake with Citrus Cream Cheese Sauce

Originally a River Cottage Veg Patch Cupcake recipe from a free booklet that came in my grandma’s paper. This is the first year I altered it slightly by making it into a Victoria sandwich styled all in one cake rather than individual cupcakes – it was little quicker and 12 pumpkin cupcakes can be hard to shift sometimes. The great thing about this recipe is that you really don’t know that there is pumpkin in it. I didn’t tell my family what the magic ingredient was the first time I made the cupcakes and they could not tell. Even my brother eats it and he is not the most ardent vegetable lover, let along pumpkin lover. Best cake to use a pumpkin in and the cream cheese icing is the perfect compliment. Who knew that citrus and pumpkin were such a lovely match? I also increase the amount of pumpkin…

A little note about the cream cheese sauce/icing: you might want to halve it as I always have too much but I just offer it as an addition as most people like to put extra with their slice. Also, mine never seems to set into icing hence why I have called it ‘sauce’. Looks prettily/spooky when it runs down the sides anyway…

Edit: After reading into it, I now know that the icing insists on using full-fat cream cheese otherwise it doesn’t set. I did use full-fat but very cheap stuff. So if you make this icing, go for full-fat, EXPENSIVE real cream cheese!

(Serves 10)

– 200g self-raising flour -1 tsp baking powder  – 3 medium sized eggs – 175g caster sugar – 300g roasted pumpkin – Finely grated zest of 1 lemon

For the cream cheese filling and topping: – 100g full-fat cream cheese – 25g butter, softened – 170g icing sugar – Finely grated zest of 1 orange

  1. Preheat the oven to 180C. Line two 20cm sandwich tins with baking parchment.
  2. In a food processor, whizz the roasted pumpkin so it is finely grated.
  3. Beat the eggs and sugar together in a large bowl using an electric whisk until the mixture is thick, creamy and pale.
  4. Fold in the flour and baking powder. Scrape the pumpkin out from the food processor and fold in, followed by the lemon zest.
  5. Spoon the mixture into the cake tins evenly and smooth down the surfaces. Bake in the oven for 30 minutes or until lightly golden and springy to the touch. Insert a cake skewer into the centers to check that they are done. If it leaves clean, they are ready. Leave the cakes to cool in their tins for at least ten minutes before turning them out onto wire racks to cool completely. This is very important as the icing will run if spread on the cakes when they are too hot.
  6. To make the icing: beat the cream cheese and butter in a large bowl using an electric whisk until the mixture is smooth.
  7. Add the icing sugar and zest. Beat until it is very light and creamy. The mixture should be slightly thickened. If it is not, add a little more icing sugar and mix in well. Cover the bowl with a plate or cling-film and refrigerate for at least 1 hour before use. This is also important as it needs to be thickened or it will continue to run off the cake.
  8. Once the cake is completely cool and the icing has been left to chill, turn one cake upside down on a serving plate and spread half of the cream cheese icing over the base. Place the other half of the cake upright on top of the iced sponge. Ice the top of the other half, spreading and smoothing it over the surface carefully.
  9. Serve cut into slices. It should keep for about 3-4 days in an air-tight container.

Powdery Mildew

IMG_1401

Following the posts about courgettes and cucumbers, I need to follow up the depressing facts about powdery mildew with a possible preventative or cure.

Grow For Flavour

I was given ‘Grow for Flavour’ by James Wong as a birthday gift a year ago. In his section about growing cucurbits, James Wong wrote about an interesting concoction he named ‘Supersquash Tonic Spray’ which I was taken by as some of my cucurbits were starting to show signs of that horrid virus, especially my pumpkins. My cucumbers and butternut squashes fortunately escaped unscathed but I was very afraid for the lives of my courgettes (which the disease did eventually slow down to a halt in early autumn) and my pumpkins (that fortunately managed to hang in there until they were ready for harvesting, then the powdery mildew reached the stems and rotted them). James Wong’s spray is for preventing the disease from taking hold of the plants but it was a little late for that last year by the time I got the book. We used it as a way of trying to hold back the disease. We don’t know if it was the tonic or just some strong cucurbits fighting for their lives, but the powdery mildew was kept at bay – it didn’t vanish but it didn’t go out of control and kill of the plants straight away.

This year, we started using the tonic spray on the plants that could possibly suffer from a powdery mildew attack as soon as they were in the ground. The weather has been so odd this year that we really do fear for any plant disease coming along so it is best to be prepared.

If you read the ‘Life’ section that comes with the ‘Telegraph’ paper (my grandma gives them to us for the chicken houses every week), then a slightly recent article written by Bunny Guinness mentioned that she now uses a 50/50 milk and water solution to spray her cucurbits with to cope with powdery mildew too.

Here is the concoction we make to help keep our cucurbits strong and healthy to fight powdery mildew when it attacks, from James Wong’s ‘Grow for Flavour’ instructions (all credit goes to the author):

Supersquash Tonic Spray

Add a splash of seaweed extract to 1 litre (1 3/4 pint) spray can of water along with a 1/4 of 300mg soluble aspirin tablet. Add a splash of full-fat milk for added nutrient content. Spritz the tonic spray over the plants’ leaves whenever you can but at least once a month over the summer. Saturate the leaves as much as you can.

The science:

  • Trials at the US Dept of Agriculture have shown that a foiler spray rich in potassium improved the quality of melons (squash’s close relative) by improving the firmness and sugar content and increasing vitamin C and beta-carotene levels.
  • Trials have demonstrated that chemicals closely related to aspirin can act as a tonic to help boost squash plant defences against drought and cold. Experimental evidence suggests that aspirin spray can improve their resistance to disease such as mildew and mosaic virus.
  • Wong emphasises using full-fat milk, not skimmed or soy. The fatty acids in milk have been shown in some trials to inhibit the growth of mildew.

Wong does point out that neither aspirin or milk are approved formally as registered pesticides or for the treatment or prevention of plant diseases. It is entirely legal though to apply them to boost plant growth and crop flavour.

As I mentioned before, all credit for the recipe and facts goes to James Wong’s published work. Give it a go!
