One of the easiest and highest yielding vegetable crops to grow are runner beans. You may not need all these 5 tips to do well but here goes:

1. I keep some bean seeds from last years crop but a new packet of seeds will germinate in May for planting out as soon as the danger of frost has gone. Alternatively buy plug plants for June delivery. Pests may eat seeds sown direct so I start each seed in a small pot.
2. Give the young plant something to climb and twine up. A 6′ cane and some wide spaced netting will do.
3. There should be no more problems before you get a crop but beans are heavy feeders and drinkers so a rich, moisture retentive soil will help and so will a good drink in dry weather.
4. Flowers, red or white are insect pollinated so do not need to be sprayed with water (an old folks tale).
5. Pick the bean pods when young and pliable. When they get a bigger bean in the pod they will stop producing new pods. Otherwise the plants will produce until October or so.
