- Female flowers of squashes of all kinds – courgettes, marrows, squashes and pumpkins – may need manual pollination with a male flower if fruit is to set.
- Long-term crops like sprouting broccoli should be generously mulched – particularly after heavy rain (or watering) to encourage water retention.
- To prevent tomato fruit blackening at the flower end (flower end rot) keep plants evenly moist.
- Spray tomatoes and potatoes with copper-based fungicide against blight (RHS, The Garden, July 2013)
- Check brassicas – broccoli, cabbage, cauliflower, pak choi etc – for mealy cabbage aphids and caterpillars.
- Water soft fruit during dry weather to encourage good fruit development.
- Fruiting shrubs and trees need more water to enhance fruiting.
- Thin apples: dessert & cooking- to 1 or 2 fruits spaced every 4-6 inches (15-23cm)
- Look out for aphids on beans etc and spray with detergent based insecticide.
- sow spring cabbages
- sow chard and perennial spinach (for crops into next spring)
- plant out young winter cabbages such as ‘Winter Jewel’ (RHS, The Garden, July 2013, p23)
- ‘bolting’ is – to cut a long story short – racing to set seed. The ‘race to the end.’ Ahem
- It’s a fever! Hot spells and drought can bring on bolting – of which many garden crops are susceptible, including lettuce, sorrel, spinach, brassicas, and so on.
- Grow succession crops to stagger stages of plant growth across a crop. (Yum!)
- Water plants regularly in hot, dry weather to minimise stress.
- Grow oriental brassicas like pak choi and mustard greens from late summer, when less prone to extremes of temperature.
- Early July sow beetroot, spinach, chard, kohl rabi & turnips for autumn crops.
- Flowers: biennials like sweet william and stock to flower the next year.
- harvet autumn-planted onions, shallots and garlic
- harvest early potatoes for best flavour when they are about a hen’s egg’s size. Lift one plant first to check tuber development.
Flower / Ornamental Garden
- divide bearded iris if flowering is declining. Replant yougest sections 12 inches (30 cm) apart.
- deadhead perennial flower beds
- deadhead roses to encourage repeat flowering
- Feed dahlia and canna with high-potasium feed such as tomato feed
- control weeds before they take over!
- plant autumn flowering bulbs such as autumn-flowering crocus
- Take internodal cuttings of ** taking cuttings above and below a node.
- Keep birdbaths and water areas topped up when weather is hot and dry.
- Fledgling garden birds will be ‘fledging’ – ie leaving their nests – at this time.
- July is peak bat watching time. Look out for them at dusk.
- Adult frogs and toads will be leaving ponds.
