Cut lawns once a week, apply a lawn weed, feed and moss killer if not applied last month. Check that herbaceous perennials that need staking have some support otherwise they can flop over and the stems can then be damaged trying to bring them upright again.
Check roses for signs of blackspot, aphids and leaf rolling sawfly damage. Tie in new stems of climbing and rambling roses to supports. Cut down daffodil bulbs now as it has been at least 6 weeks since they flowered. Dead-head and cut back oriental poppies after flowering to stimulate new foliage.
Keep on top of weeds. Pinch out any side shoots from your tomato plants, these can then be potted up to create new tomato plants. Start to feed tomato plants once the first truss is setting fruit. Keep an eye on your onion and garlic.
When the leaves start to yellow and die back, they’re ready to harvest. Harvest early potatoes – these are normally ready about 10 weeks after planting.
