Activities in your vegetable garden in August are a combination of ensuring that you have a supply of vegetables through the autumn and winter and also planting winter vegetables that will be ready to harvest in the Spring. So you’re looking at vegetables that will crop quickly for Autumn as well as those that will bring some vitamins to your diet during the winter months. There is, to a certain extent, a race against time, you’ll need to get some of the vegetables planted and sown, as if you leave it until September, then the plants won’t have grown enough to survive the winter. Here’s our guide to what vegetables to plant in August.
What Vegetables to Plant in August
August is a great time in the vegetable garden – you’ll be into a rhythm of succession sowing, and harvesting and now you’ll be ready with some space to get some autumn cropping and winter harvesting vegetables into the ground. We also recommend chilling out and having a relax. Don’t forget if you’re taking a holiday to leave someone in charge of making sure your garden is watered and with a list of things to do!
Sow Cabbage Seeds In August
August in the UK is a good time to be thinking about what you’ll want to harvest NEXT Spring. In August you can sow spring cabbage outdoors. Cabbage is a great winter vegetable to plant in August, it means that your cabbage will get a good start and have decent roots which will help them to resist bad weather and frosts over the winter. We recommend using netting to keep pigeons and other pests off them! These are an awesome option for cabbage seeds.

We haven’t touched on chard yet as it tends not to be a beginner vegetable to grow, but if you’re itching to get started growing something different besides the basic UK vegetables then we recommend chard.

Sow Chicory in August
Chicory is a hardy vegetable and you can sow chicory from February to September – so get some in the ground in August and you’ll get a good crop during the winter months. You’ll likely be better to start the seeds inside or in a propagator and then plant them out into a sunny spot in the garden once they’re a little more established.

Lettuce and Salad leaves, especially wild rocket are great for sowing in August. Some lettuces are particularly hardy and can be grown throughout the winter, and picked as leaves April to June. If you sow lettuce in August you’ll be able to harvest it in April. Get a sowing of rocket in August and you’ll get heaps of rocket leaves in Autumn.

What Jobs to do in the Vegetable Garden in August
August is a great month to plant quick cropping vegetables to give you fresh veg during Autumn. It’s also a good month to be sowing seeds for an early spring harvest. You’ll also want to pay attention to a few jobs that will need doing in the vegetable garden during August.
Harvesting during August
If you’ve been succession sowing vegetables since earlier in the year you’ll want to keep harvesting – for many vegetables regular harvesting ensures that they continue to crop, so keep harvesting and you’ll get better results. Harvest vegetables as soon as they are ripe. Most vegetables are best when they’re young and fresh – don’t let the courgettes become huge, or the tomatoes become overripe. If you end up with a glut of courgettes, tomatoes, or other vegetables and fruits, then get practicing your jamming and chutney making skills – our guide here helps you with more!
Leaving fruits and vegetables on the plant can reduce the crop that you get, harvest regularly and often and your plants will produce more. If you’ve got more than enough for your own use why not set up a swap, or give away your produce to friends, family, and neighbours.
Keep Watering Your Vegetables in August
Regular watering is key during the hot months of the year and August is no exception. Watering on a night once the heat of the sun has gone is best. Aim to water, in general, the soil at the base of the plant, rather than the leaves, as the sun can cause the leaves to burn.
Don’t forget to add to your compost in August!
Once you’ve picked your fruit and vegetables and sorted out any weeds, then put all of the healthy leaves into your compost bin. If anything looks like it has disease then do not put it in the compost.
What Vegetables to Harvest in August
Vegetables that will be ready to harvest in August include courgettes (always!), cucumbers, onions, garlic, French beans. Tomatoes and sweetcorn will also be ready. Aim to eat your sweetcorn as soon as you pick it and you’ll never buy another corn cob from the shop again!
When it comes to root vegetables, in general, its best to only harvest what you’re going to use as they tend to store better in-ground for a period of time.
Final words on what vegetables to plant in August
While you’ll be harvesting herbs and vegetables that you planted earlier in the year during August, this month is also a great time to get started planting what you’ll want to harvest in the spring months. There’s also the opportunity in August to plant quick cropping vegetables that will give you a burst of fresh vegetables in the autumn months and even some that you can eat during winter.
