July to do list

1.  Regular deadheading bedding and perennial plants directs energy into stronger growth and more flowers. Once the flowers are pollinated; seed heads, pods or capsules form at the expense of further growth and flower development.  However do not remove the faded flowers on plants that produce seed loved by birds, including Rudbeckia, cornflower and sunflower, or plants that have ornamental seeds or fruits; examples include alliums; love-in-a-mist (Nigella), stinking iris (Iris foetidissima) and bladder cherry (Physalis alkekengi).  There is also no need to deadhead rose cultivars that bear hips or other plants that bear berries in the autumn. 

2. Keep up with the harvesting of all crops. Lift early potatoes and carry on earthing up the rows.  

When the potatoes are 10cm tall, the leafy shoots can be mounded around with soil to their full height, this process is known as ‘earthing up’. Earthing up potatoes will increase the length of underground stems that will bear potatoes. This mounding can be repeated once or twice more at 2 – 3 week intervals to ensure the best crop, with the added benefit of smothering any competing weeds.

 

Loosen soil between the rows using a garden fork. Use a rake or spade to draw the soil into a ridge along the length of the row around the emerging stems of the potatoes. Leave a shallow trough along the row at the top of the ridge to channel any water down to the developing tubers.

 

When growing potatoes in large pots or sacks, the tubers will have been planted into 10cm of compost at the base of the container. As the shoots emerge, add more compost at regular intervals, 5cm at a time, until the container is almost full.

 

On light soil, mix in well-rotted garden or bagged compost to earth up the potato plants. This helps conserve moisture which swells the tubers. 

3. Harvest garlic and shallots as the foliage begins to become yellow and straw. 

4. July is the start of globe artichoke season. If your plant is into its second year then cut off the top bulb once big and swollen with a couple of inches of stem attached.

 

5.  Lift autumn planted onions for immediate use. Continue to pick rhubarb until the end of the month and begin to harvest the main crop of your strawberries. Start to pick plums, early pears and apples.

 

6. Start sowing the seeds of the overwintering crops of kales, spring cabbage, radicchio, chicory, spinach beet and a hardy type of onion to mature in the early summer of next year.

 

7. Now is the best time to sow the main crop of carrots to avoid attack from root fly.

 

8. Continue with successional sowings of beetroot and lettuce. Follow the instructions on the back of the seed packet, and sow every 2 - 4 weeks for a continuous supply of crops.

 

9. Aim to keep the hoe moving at every opportunity. Water all crops at least once a week. Start to draw the soil up around the base of Brussels sprouts and sweet corn plants to encourage extra roots.

 

10.  This is the start of potato blight season, and if the weather is wet and humid in July then your crop is likely to be at risk. You can use fungicides containing copper to help protect your crop from the blight; these should be sprayed from June onwards if a wet July is predicted. (Crop rotation the following year is advisable). An infected plant will have a watery rot on its leaves, causing them to collapse – the infected matter should be binned or burned and not placed into your compost, as this will not kill the disease and it will reoccur the following year.

 

Recipe of the Month Easy Spinach Soup (serves 4)

Ingredients

20g butter

2 medium onions, sliced

1 clove of garlic, sliced

2 medium potatoes, peeled and chopped into 1cm cubes

1.25 litres chicken stock

300g baby spinach

nutmeg

The juice of ½ a lemon

4 tbsp single cream

 

Method

Heat the butter in a large sauce pan over a medium-low heat and add the onions. Cook gently for 7-8 minutes or until soft (but not brown). Add the garlic and potato cubes and cook, stirring, for an extra 2 minutes.

Add the stock, increase the heat and bring to the boil. Reduce the heat and simmer gently for about 10 minutes. Add the spinach leaves, increase the heat again and simmer for a further 10 minutes.

Remove from the heat and allow to cool a little. Purée the soup in batches in a blender or with a hand-held blender until smooth. Season with some freshly grated nutmeg.

Add lemon juice and season to taste with salt and freshly ground black pepper. Bring the soup back to the simmer and then stir in the cream.

Tip - This can be made 48 hours ahead of time. Don't add the lemon juice or cream until reheating the soup.

Call it cheating, but applying used coffee grounds, eggshells, chopped-up banana peels, and other organic matter directly to your soil (no composting required) can offer plants nutrients as they decompose.

For already-growing beds, scatter and bury the items within the first few inches of soil.
