Broccoli, Brussels sprouts, Cabbage, Cauliflower, KaleNasturtiumCabbage white butterflies will happily lay their eggs on Nasturtium leaves. Once the eggs hatch, the caterpillars will nibble your Nasturtiums and not your crops!
Broccoli, Brussels sprouts, Cabbage, Carrot, Cauliflower, Kale, Onion, Radish, TomatoesMintTo deter flea beetles, aphids, and to confuse carrot root fly/Onion fly, who find their host through scent. Keep the Mint in a pot if possible, as it quickly spreads and will smother your crops!

Asparagus, Courgette, TomatoesCalendula (Pot Marigold)Calendula is very attractive to pollinators as it’s long flowering period means it can provide nectar over the whole growing season. It can also repel Asparagus beetles and unwanted soil nematodes.

Mint, Calendula and Nasturtiums (L-R) are all great companion plants!

Here’s a few other tips and ideas that will help you make the most of your planting:

  1. Create partial shade for shorter crops by planting tall plants, such as peas or sweetcorn. Some plants, namely coriander, lettuce and spinach are prone to bolting. This is when a plant produces a flowering stem before harvesting, as a natural attempt to produce seeds as a means of survival and happens when the plant is stressed (including high temperatures).
  2. Plant herbs throughout the plot, their strongly scented leaves will help repel the less useful of insects and their flowers will encourage pollinators.
  3. Utilise your space! Plant fast-growing crops such as lettuce and radish between slower-growing crops like root vegetables and Brussels Sprouts. Not only does this make your yield per square inch larger, they’ll help prevent weeds growing!
  4. Encourage wildlife into your garden. Butterflies, moths, beetles, birds, bats and millions of other insects all play an important role in keeping your garden happy. Sow lots of wildlife friendly seeds to bring natural predators that will help keep slugs and aphids at bay, to encourage pollinating insects, or simply to bring a little bit of life into your space.

You’ll be amazed by the variety of colourful veg you can grow when starting from seed, and we hope that you’ll be bringing better nutrition and outstanding homegrown flavour to your table all year round using these handy tips!
