August
In The Vegetable Garden This August
August is a peak month in the vegetable garden — lots to harvest, still time to sow, and plenty of maintenance to keep things productive. Here’s a list of top tips for your vegetable garden in August:
🥕 1. Harvest Regularly
- Pick little and often to encourage more production.
Watch for:
- Beans and courgettes (they’ll stop if you leave them to grow huge)
- Tomatoes, cucumbers, sweetcorn, beetroot, potatoes, carrots
- Salad leaves — cut-and-come-again types can still thrive
🌱 2. Sow for Autumn and Winter
Still time to sow fast-growing crops and hardy greens:
- Radishes
- Spinach
- Pak choi
- Rocket
- Winter lettuces
- Spring onions
- Turnips
- Spring cabbage (sow now for planting out in September)
Tip: Use mesh or fleece to keep brassica pests (cabbage white butterflies, flea beetles) at bay.
💦 3. Watering and Feeding
- Water deeply and early or late in the day to reduce evaporation.
- Feed fruiting plants (tomatoes, cucumbers, peppers) weekly with a high-potash feed.
- Mulch where possible to retain moisture and suppress weeds.
🧄 4. Plan for Next Season
- Clear spent crops and prepare beds for autumn planting.
- Start planning where your overwintering garlic, onions, and broad beans will go.
🐛 5. Watch for Pests & Diseases
- Check brassicas for cabbage whites – remove caterpillars and eggs from undersides of leaves.
- Keep an eye out for blight in tomatoes and potatoes – remove infected foliage immediately.
- Net vulnerable crops (like brassicas and carrots) against pigeons, butterflies, and carrot root fly.
🌾 6. Earth Up and Support
- Earth up leeks and celery to blanch stems.
- Tie in tall crops like climbing beans and tomatoes to prevent damage from August wind.
🧺 7. Dry or Store Surplus Crops
- Dry onions and garlic once tops flop over — cure them in sun or a well-ventilated shed.
- Start curing potatoes (cut foliage 2 weeks before lifting for better skin).
- Freeze or preserve excess beans, courgettes, and herbs.
🔄 8. Succession Sowing
Keep sowing quick crops like:
- Lettuce
- Rocket
- Mizuna
- Radishes
You’ll stretch your season well into autumn.
🐝 9. Attract Pollinators
- Leave a few herbs (like basil, coriander, or chives) to flower.
- Helps keep bees and other pollinators in your garden for late crops.
This Month's Key Tips
- Deadhead flowering plants regularly.
- Keep ponds and water features topped up.
- Watering - particularly containers and new plants, preferably with recyled water or stored rainwater.
- Harvest vegetables regularly as they become ready to promote new growth.
