Borders and Containers
- Deadhead bedding plants and perennials to ensure continued flowering over the summer months
- Cut back plants in baskets and feed to encourage new growth and revive your basket display
- Fill in patchy areas in rock gardens with gritty compost which will encourage re-growth
- Water tubs and new plants if they are looking dry
- Continue to feed and water established plants and vegetables
- Take cuttings of patio and container plants for next year
- Watch out for aphids on stems and leaves of young shoots
- Look out for black sport, mildew and aphids on roses
- Mulch borders to help retain moisture and reduce weeds
Grow Your Own
- Sow spring cabbage, turnips, Oriental vegetables, chicory, fennel, and autumn/winter salads and plant out leeks and brassicas for a winter supply, if not yet done
- Carrots can still be sown, but beware of carrot fly when thinning existing seedlings.
- Complete summer pruning of gooseberries and redcurrants and white currants.
- Watch out for potato blight and tomato blight.
- Keep an early eye out for the sunken brown patches of blossom end rot on tomatoes.
- Complete summer pruning of gooseberries and red/white currants.
- Pull off suckers appearing around the base of fruit trees.
- Make sure fruit isn’t drought stressed, especially those in containers, against a wall or newly planted.
- Protect heavily-laden fruit tree and bush branches against snapping under the weight. Use a stake or prop to keep them upright.
- Ensure all vegetables get a regular, consistent supply of water. This will aid healthy development, and help to avoid diseases, disorders and bolting.
- Continue to hoe off weeds in dry weather. Done in wet weather, the weeds are liable to re-root.
- Don’t forget to stop cordon tomatoes by removing the main shoot. Look for the leaf that’s above the fourth truss (set of developing fruit) and cut it off here. This should ensure that all the fruits ripen by the end of the season. Bush tomatoes can be left to their own devices.
- Climbing beans may also need stopping, to maximise cropping on existing sideshoots. Stop them when they reach the tops of their supports.
- Beans need sufficient watering to help the seed pods set.
- Check climbing vegetables are securely tied to supports.
- Give your lawn a quick acting summer feed if you didn’t feed in spring – a soluble feed and weed product is good if weeds are present. Isolated weeds can be spot treated with a weed gel or gun.
- Keep mowing regularly however in hot weather, set your mower at a slightly higher level to prevent your lawn drying out. As lawn growth slows down towards the end of summer, keep the cutting height raised to help your grass resist the wear and tear of summer use.
- If using a sprinkler, place a jam far or an empty tin can on the lawn and leave the sprinkler running long enough to collect 0.5in of water in the bottom. This ensures enough not to waste water, while wetting the roots sufficiently.
