Seeds to sow in June

Although it’s too late to sow slow growing crops, there is still time in June to sow lots of vegetable seeds that you will be harvesting in the months to come.

June is a busy month in the garden as you begin to harvest and maintain crops.

As well as sowing new seedlings you will also want to make sure that you are preparing seedlings that will replace crops that are currently giving you produce (this is called succession sowing).

Sowing Beetroot In June

You can continue sowing beetroot through June and a sowing at the beginning of June and again at the end of the month will lengthen your harvest into Autumn.

Sowing Courgettes and Squashes In June

The soil is warm enough In June to sow courgettes and squash directly outside although you can still do so in pots to protect from slugs! Pop two seeds in together and if both germinate then pull one up as it’ll need lots of room to grow.

Sowing Carrots in June

You still have time to sow carrots in June and they should be ready to harvest in September or October.

Sowing Peas in June

There is still just enough time to direct sow some mangetout, sugarsnap or maincrop peas at the beginning of June and will be ready in 13-16 weeks. Towards the end of the month you can choose faster growing dwarf varieties.

Sowing Lettuces in June

Lettuces are difficult to germinate in hot weather so sow in a cool spot to harvest through summer. Choose leaf varieties for cut and come again lettuce or choose a lettuce that grows a heart and is harvested hole (you can still pick just the outside leaves to prolong the harvest).

Sowing turnips now will give you a crop in late Summer .

Sowing Beans in June

Sow more beans now to lengthen your bean crop. June really is the last month for sowing beans and a batch of runner beans sown late June should crop as late as October if the weather is mild.

Sowing Brassicas in June

Kale and late sprouting broccoli seeds can be sown in June. Depending on the varieties you will be able to harvest later this year or overwinter them for an early crop next year.

You can also sow Calabrese but it is best sown in the ground where it will stay as it won’t like being moved in warm weather.

Kale seeds can be sown closer together if you want small leaves for salads.

Sowing Swiss Chard in June

Swiss chard is one of my favourite crops as not only is it great in Summer salads and stir-fries, it will also crop through winter and into the next Spring! Plants add a lovely colour to the garden too with their red, white and yellow edible stalks. Dot them around and plant in small clusters for salad leaves.

Sowing Spring Onions in June

Sow spring onions thinly in drills for a quick crop.

Sowing Sweetcorn in June

Sow sweetcorn in a block of at least 12 ideally as this will help with pollunation.

Sow rows or clusters of radish in June for a quick crop. Radish seedlings are just one of the many edible vegetables seedlings.
