If you want an early crop, sow the seed of a hardy variety outdoors the previous autumn. Or you can sow seed from early spring onwards.
You can also sow the seed under cover, making sure you harden the seedlings off before planting them out. Aim for a series of small, successional sowings of eight to 12 seeds.
Sow individually at a depth of 5cm (2in), around 23cm (9in) apart. They take nine to ten weeks to mature.

Potato Pete Posted at 07:29 on Sat, 10/18/2008Blackfly are a common problem with broad beans, though even heavily infested plants will still produce an adequate crop of beans in my experience. Blackfly and other aphids are easily controlled using a soap- or fatty acid-based organic
insecticide, or you can make your own by diluting some washing-up liquid in a sprayer. Pinching out the tips of the plants is also supposed to help control blackfly, but I haven't personally found that it makes much of a difference.

Gra Posted at 15:41 on Fri, 01/15/2010Growing nasturiums nearby will attract the blackfly away from your broad beans. We suffer far, far less problems with blackfly than our neighbours and they are edible, attractive and also cabbage white butterflies prefer them to brassicas.
Only problem is that they are self-seeding and unless hoed off when small can overrun the place.
