Summer Seed Sowing

The Summer Sowing Guide
for the second sowing time of the year

People often ask us what they should be sowing from June on through the summer.

So, we've tried to list here the main things that we'll be sowing from midsummer onwards into the autumn for a good supply of vegetables right through the winter and into next spring.

Don't be put off summer / autumn sowings if you don't have a polytunnel or greenhouse, most of these veggies will grow outdoors quite happily outside in most of the country.

Any protection you can offer will help - mini plastic and fleece tunnels are an easy modern alternative to traditional cloches. Often just keeping cold winds off your plants is all that is needed to give you a really successful crop.

ORIENTAL GREENS - milder greens for salads, or tasty mustard greens
There are a whole range of remarkably cold hardy oriental greens. They are ideal to keep your plot going through the depths of winter, particularly jf you don't have the space or time for traditional winter veg like brussels.

Many are good both in salads and cooked - try Pak Choi, Mizuna, 'Pe Tsai' Chinese Cabbage, Mibuna, Tatsoi and Mispoona, all of which can be sown from the end of June through to end September (you can keep on sowing through into the winter if you have a polytunnel or greenhouse)

Mustard greens are even more hardy than the milder greens - which means that they will keep on growing new leaves even in the worst of weather. Raw they are spicy - so although its nice to put small quantities raw in salads, they're mostly used cooked. When you cook them the heat disappears, leaving a rich, full flavour, with just a little spicy zing. They are especially useful because they grow so well in cooler weather.

Bunching Onions are MUCH easier to grow from seed than normal onions. They're really quick and useful, providing lots of greenstuff early in the Spring Gap when there's not much else available. Sow them after midsummer for a winter/spring crop

Not everyone realises that Fennel is best sown after midsummer as its much less likely to bolt than if its sown in spring. Sow up to the middle of August. The plants will stand up to Christmas or beyond in milder areas.

Kales are great for baby leaves (salads & cooked) in autumn, and then left to overwinter for delicious greens through to the following April.
You can sow kale 2 ways:
1) in autumn in a tunnel - for tender baby leaves. We particularly recommend Nero de Toscana for this use, although all the kales will do well.
2) outdoors before early August - for hardy overwintering plants. Try Red Ursa for a very good hardy variety that also makes delicious flowering shoots in spring

Winter lettuce are particularly cold-hardy, selected for sowing after mid-summer, for harvest in autumn - and with a bit of protection, on into winter. Ideal if you have a polytunnel and want winter salads - or outdoors under a cloche or mini-tunnel. Try Winter Marvel which can be sown right through into November.
Also keep on successional sowing summer lettuce varieties in July - August to give you a wide range of salads in Autumn.

Land Cress (Barbarea verna) is great in salads but can also be eaten cooked as 'creasy greens' or as a pretty much identical substitute for watercress in soup. It is sown in autumn & grown over winter, its a great addition to winter salads!
Also try 'Bianca Riccia da Taglio' Salad Endive, which is hardier than lettuce, and has pretty pale green leaves with a good non-bitter flavour, it can be sown spring, summer or autumn.
And don't forget plenty of mizuna, chinese cabbage and mispoona, which will give you endless delicious salads through the worst of the winter

These are a fantastic root vegetable that everyone should try. They bear no resemblance to a breakfast radish, this is a large root - tennis ball sized and upwards - which you use in soups, stews and stir-fries. They are also great eaten raw grated or sliced finely into salads, with a mild zing to them. Try Weiner Runder Kohlschwarzer which is delicious in a stir fry, or used like a swede or turnip in soups and stews. We find them less fussy than either of those two vegetables, and sow them from July to Sept, for pulling all winter.

Beetroot are ideal for sowing outdoors or in a tunnel in July and August for pulling as tender baby beet in autumn.
Also, don't forget that you can store your main crop of beetroot for winter use by pulling in autumn, twisting off the leaves, and packing into dry sawdust. Make sure that the roots don't touch, and they should store through until well into the new year.

Sow our quick headingbroccoli outdoors in midsummer for autumn harvest, or as long as the winter is not too severe, it can be sown in late August or September in an unheated greenhouse or polytunnel, to give you a very early crop at the start of the following year.

Broccoli Raab is related to turnip - but is grown like broccoli & produces delicious sprouts like a slightly spicy flavoured sprouting broccoli.
Thinnings are also excellent in salads or stirfries. Sow mid to late summer for harvest just 40 days later - so great in late summer & autumn when ordinary broccoli isn't available.

Sow ‘Precoce de Louviers’ Spring Cabbage in late August or September, and you'll get nice fresh cabbage very early the following spring.

Carry on sowing carrots in July and August to pull as tender carrots in autumn. We recommend 'Giant Red' Dark Orange Carrot as the best for summer sowing. The vigour and flavour of this Italian variety are terrific.

Sow leaf beet and chard up until end July for a seemingly endless supply of greens in autumn and into next spring.

Also try ‘Rapa Senza Testa’ Turnip Greens for an excellect quick growing green vegetable. Ready about 4 weeks from sowing, it makes mild green leaves that have a wonderfully buttery flavour when cooked, and are also nice and mild if used raw in salads.

Successional sow Coriander until the end of July for a continual supply of fresh leaves. Parsley can also be sown up to midsummer and will stand through intot he winter with a bit of protection.

Sow round seeded varieties in September and October for an extra-early crop in spring, or from January onwards. Try Hatif d'Annonay as a dwarf variety, or Amelioree d'Auvergne if you prefer a climbing pea.

Sow turnips from mid June through to end July for pulling through the autumn and into the winter for all those lovely winter stews. Or cook them as my mum does, braised in the oven and served with a roast leg of lamb - delicious!

Sow swedes from early June until mid July for harvest in November/December - they will also store well in a cool place until well after Christmas. Excellent as an addition to winter vegetable soups (including the traditional Welsh cawl), roasted around the joint, or mashed with loads of butter and some ground black pepper.
