French Beans, the dwarf types, grow extremely well in raised beds, far better than they do in open ground. The reasons are simple. French Beans prefer a light, open and well dug soil with lots of warmth. The soil in a raise bed fits these conditions far better than the open ground. The soil itself is ideal and being raised it retains heat very well.


RECOMMENDED VARIETIES OF FRENCH BEANS FOR RAISED BEDS
Always choose dwarf varieties, not the climbing varieties. Aside from that the particular variety is a matter of choice. this year we have chosen Nomad, a variety which reaches about 45cm / 18in high and produces a good crop of tasty French Beans, they also have good disease resistance.

There are however lots of excellent varieties available. some with purple pods such as Purple Teepee. The colour is something of a novelty however because the pods colour to green when they are cooked.

WHEN TO SOW FRENCH BEANS
If you are sowing directly in the soil then sow French beans when all danger of frost has passed. French Beans are destroyed by frost and the beans themselves will rot in the ground if they do not germinate very quickly. The average date to safely sow French Beans in the UK (for example Birmingham) is early to mid May. If you live in a warmer part of the country sow a couple of weeks of earlier or later if you live in a cool part of the country.

You can easily get a two week start though by sowing French Beans in 7cm / 3in pots in late April and keep them on a window sill. They will germinate after week and be ready to transplant into the raised bed in early to mid May. French Beans transplant very well.

Because French Beans are so productive it is very likely that you will end up with too many of them. So we suggest sowing some in pots in late April and then some more in the open ground during mid to late May. that will extend the cropping period considerably.

HOW TO SOW FRENCH BEANS
It's simplicity itself. If sowing the beans in pots first, simply fill the pot with general multi purpose compost make a little hole in the top of the compost and place two beans in the hole. It doesn't matter at all what way up the beans are placed. Cover the beans with compost so that they are 2cm / 1in covered and water them well. Place them in a frost free and light position in the house but not in direct sunlight. A windowsill is ideal.

As soon as the French Bean seedlings appear, pull out the weakest growing one and throw it away leaving just one strong growing French Bean plant.

Two to three weeks after sowing the beans they will be ready for planting out but only do this when all danger of frost has passed. Make a hole in the raised bed slightly larger than the size as the pot, turn the seedling and compost out of the pot and place in the hole. Gently firm soil around the seedling and then water well.

Sowing French Beans directly in the raised bed is simple as well. With a trowel or pencil, draw a line in the soil about 4cm / 1½ deep and place two beans in the line every 15cm / 6in and cover them with soil. Water well and wait for germination which will take around 10 days depending on the temperature.

When you sow the French Beans directly in the soil scatter some blood, fish and bone fertiliser over the soil and gently work it into the surface. Do the same when you transplant pot grown ones.

CARE OF FRENCH BEANS

French Bean seedling

The first consideration is frost. If your French Beans are threatened by a late frost cover them with horticultural fleece or even newspaper over night.

Water is the main requirement of French Beans especially in a raised bed. Don't let the compost dry out and water frequently as explained here. Feeding with a general purpose liquid fertiliser as explained by clicking here will be more than enough for French Beans.

Pests are few as far as French Beans are concerned. Birds do sometimes peck out the very young seedlings and because the soil in a raised bed is loose, the birds can easily remove the whole seedling. If this is a problem in your area then cover the raised bed with horticultural fleece until the plants are 10cm / 4in high.

Slugs may also be a problem when the seedlings first emerge and the weather conditions are damp. With a raised bed it's easiest to cover the new seedlings with horticultural fleece for a week or two until they get tall enough to be of no interest to the slugs.

Dwarf French Beans will support themselves in many conditions but some support will minimise damage from winds and help to support the pods off the ground. Twigs about 45cm / 18in high are ideal for light support. The plants will simply grow into and around the supports.

HARVEST FRENCH BEANS
Harvest French Beans by cutting off the pods with scissors or a knife. If you try and pull the pods off there is a real danger that the whole plants will be damaged.

Harvest frequently because leaving the pods on the plant too long will stop it cropping.

French beans will store in the fridge for three of four days. Many people freeze them but personally we don't like French beans after they have been frozen, the texture changes significantly. Give excess beans away to friends and family or freeze them for inclusion in soups.
