August is a month of transition in the garden, where the lush growth of summer meets the early whispers of autumn. The days are still long and warm, making it a key time to maintain the momentum of your garden’s growth while also preparing for the seasonal changes ahead.
Whether you’re tending to your lawn, harvesting your summer crops, or planning for autumn plantings, there’s plenty to keep you busy this month.
Here’s a guide to the essential gardening tasks for August:
1. Watering
Early morning or late evening is the best time to water your garden, ensuring the moisture reaches deep into the soil. Avoid overhead watering, as wet foliage can invite diseases.
For pots and containers, daily checks are crucial - consider mulching them to reduce evaporation.
What is mulching? Mulching is the process of covering the soil around plants with a protective layer of material. This layer can be organic, like compost, straw, bark, or leaves, or inorganic, like stones or plastic sheeting. The primary purposes of mulching are to retain moisture in the soil, regulate soil temperature, suppress weed growth, and improve soil fertility as the organic mulch decomposes. Mulching also helps prevent soil erosion and can enhance the visual appeal of your garden by providing a neat, finished look.
2. Deadheading and Pruning
Regular deadheading of flowers like roses, dahlias, and geraniums will encourage continued blooming throughout August.
For shrubs like lavender and rosemary, a light prune after flowering can help maintain their shape and vigour, setting them up for a healthy season next year.
3. Harvesting
This is the height of the harvesting season for many fruits and vegetables. Keep on top of picking crops such as tomatoes, courgettes, beans, and cucumbers. Regular harvesting not only encourages more production but also ensures the best flavour.
Consider freezing, drying, or making preserves to store your bounty. Additionally, pick herbs like basil, parsley, and mint before they go to seed.
4. Sowing for Autumn
August is the perfect time to start sowing seeds for autumn crops. Here are some ideas:
• Leafy Greens: Sow hardy varieties like spinach, kale, and chard. These greens thrive in cooler temperatures and can provide a fresh harvest into the autumn months.
• Root Vegetables: Consider sowing turnips, beets, and radishes. These quick-growing root crops can mature before the first frost and add variety to your autumn table.
• Brassicas: Plant cabbages, cauliflower, and broccoli for a late autumn or early winter harvest. These crops can tolerate cooler temperatures and will thrive as the weather begins to cool.
• Herbs: Perennial herbs like chives and parsley can be sown now, providing a fresh supply through the autumn and even into winter with some protection.
• Spring Bulbs: Although not an autumn crop, now is the time to plant bulbs like daffodils, tulips, and crocuses to ensure a colourful display next spring.
5. Lawn Care
During the hot weather, raise the cutting height of your mower to leave the grass slightly longer, which helps retain moisture. Water deeply once a week, if there has been no rainfall. You can also give your lawn a light feed with a summer lawn fertilizer to strengthen it against the stress of the heat.
6. Pest Control
Warm weather can bring a surge in pests. Here are some eco-friendly options to protect your plants:
• Handpicking: For pests like caterpillars and slugs, simply removing them by hand is effective. Do this early in the morning or late in the evening when they are most active.
• Neem Oil: An organic pesticide, neem oil is effective against a wide range of pests including aphids, whiteflies, and spider mites. It disrupts their feeding and breeding, reducing infestations without harming beneficial insects.
• Soap Spray: A simple solution of water and mild soap can help control soft-bodied insects like aphids. Spray it directly on the pests but avoid using it during the hottest part of the day to prevent leaf burn.
• Companion Planting: Use plants that naturally repel pests, such as marigolds, which deter nematodes, and basil, which repels mosquitoes and flies. Companion planting can help protect your crops without the need for chemical treatments.
7. General Maintenance
August is an ideal time for a garden tidy-up. Remove any dead or diseased plant material to prevent pests and diseases from spreading. Clear out weeds before they set seed, and top up mulch around plants to conserve moisture and suppress new weeds.
Check garden structures like trellises and stakes to ensure they are still secure, especially after strong winds or heavy rains!
