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.
