In The Flower Garden
- Pick bulbils from lily stems and pot them up to raise new plants
- Give shrubs and perennial plants a liquid feed
- Cut down delphiniums once flower spikes fade
- Take cuttings from non-flowering shoots on hydrangeas
- Pick sweet peas regularly and remove any seed heads to keep them flowering
- Shorten shoots on choisya to encourage a second flush of flowers
- Feed roses to keep them flowering strongly
- Pinch out the shoot tips on fuchsias and bedding plants for bushier growth
- Save seed from foxgloves and sow right away in small pots of compost
- Be vigilant for signs of lily beetle, vine weevil, Solomon’s seal sawfly and other problem pests
In The Fruit and Vegetable Garden
- Pick gooseberries when ripe. If they’re still very green, small and hard, leave them a bit longer. Some varieties turn red or white as they ripen
- Prune bay trees to keep them in shape
- Spray apples and gooseberries with a fungicide to protect against mildew
- Lift early potatoes
- Pick mangetout peas and beans
- Spray gooseberries to prevent sawfly attack
- Sow an autumn crop of peas before mid-July
- Tie in new growth on cordon-trained tomatoes and pinch out sideshoots. Bush varieties can be left to scramble over the soil
- Water runner beans, celery, marrows, courgettes and salads
- Sow seeds of salad leaves, beetroot, radishes, spring cabbages, kohl rabi, Swiss chard, spinach, Oriental greens, chicory, swede and turnips for green tops
In The Greenhouse
- Repot any plants that are pot bound or getting top heavy. Tall plants are best placed in terracotta pots for extra stability
- Open all vents and prop doors open on warm days to improve ventilation
- Bring large-leaved houseplants into the garden and hose them down to clean off dust. Wipe dry and apply a leaf shine for an attractive glossy finish before bringing back inside
- Thin bunches of greenhouse grapes
- Take cuttings from pelargoniums, fuchsias, marguerites, penstemon, carnations, diascia and many others
- Damp down the greenhouse floor each morning on hot days to increase humidity
- Stand pot plants on capillary matting, or in trays of gravel and water, so they don’t dry out
- Hang up sticky yellow traps to catch whitefly and flying insects
- Propagate houseplants, including monstera, dracaena and croton, by air layering
Generally
- Pick herbs, lavender and everlasting flowers to hang and dry
- Be on the lookout for developing pest problems and take action
- Dig out problem lawn weeds or treat with weedkiller
- Re-seed bare patches in lawns
- Wash out pond filters
- Water hydrangeas with a colourant solution if you want blue flowers
- Use a circuit breaker (RCD) when using electric tools
- Scoop floating weed from ponds with a net
- Trim hedges and topiary
- Top up bird baths regularly
