How we try green beans

We grew green beans and recorded when the first flowers appeared on each of our varieties. And when they started making beans, we picked the beans, weighed them, and gave them a weekly grade. We also appreciate how easy the beans were to pick.

When to sow

Avoid excess beans

Beans produce plenty of grains. In order not to get overwhelmed, the trick is to grow the right number of plants for your needs. By doing Which? Garðablað In the experiment, most varieties produced at least 0.5 kg per plant and our Best Buy wild beans produced up to 1 kg per plant in one season. One wigwam of dozens of plants would be enough for a small home.

How do climbing beans and peas relate to each other?

When climbing, beans are a little sweeter and juicier than Runner beansThe real difference is that they are not that strong or narrow. Most of the strains we tested gave wireless soft beans, even though they were quite large on the plant. Our best buy will also yield great results. Crossed beans and peas do not require pollination and are therefore more reliable than Runner beans


Green beans need warm soil and are very sensitive to frost. Start with seeds in the greenhouse in late April to May using a measuring tray or small pots filled with Best Buy compost to sow seeds


Wait until the chances of frost have passed (late May to June) to sow directly into the ground. Sown about 1.5 cm deep in double rows at 15 cm intervals. Sow one at a time to prolong the harvest.

Take care of your plants

To provide support for climbing beans

Use bamboo poles that are at least six feet high and firmly pressed into the ground. You see all sorts of imaginative structure in the allocations, but when what? While working in the garden, we tried bean supports and found that the three best methods were: wigwam, X-frame and A-frame.

A wigwam is quick and easy to set up. It also has a neat, tight shape that takes up little space.

The X-frame is made of two bamboo poles glued at a 45 degree angle to the floor, crossed in the middle and tied in the middle. This is reinforced with a horizontal bar located where the bar intersects. The beans are easy to pick as they hang from the outer edge of the carrier.

A-frame is very strong, easy to assemble and disassemble and is good in the fight against weeds.


Hardening of the plants began in the greenhouse before they were planted outdoors after the last frost (mid-May to early June, depending on where they live). There were 6 inches left between the plants. If late frosts are expected after planting, protect the plants with a layer of garden chips.

Most dwarf green beans need no support, but in exposed areas or when the plants seem a little elongated, a few twigs or sticks and a string will do the job.

to water

Water well during dry periods; Covering the soil with mulch from used fungal or garden mass keeps the moisture and the weeds will remain.

How and when to harvest

Harvest in: July to October

Choose when the beans are 4 to 5 inches long and before they show signs of sowing. It is best to cut the beans with scissors or pinch them between the finger and thumb. If you pull on the beans, there is a risk that you will dig up the whole plant if it is a dwarf variety. Do not let the pods age on climbing beans unless you want to save seeds. Regular harvesting encourages the plants to produce a lot of beans.

If you are looking to save seeds, especially if you are growing an open pollinated variety, leave the beans on some plants and let them dry until the beans rattle in the pods before collecting them.

Common growth problems

Yellow plants

Planting too early at low temperatures causes the bean plants to turn yellow and not thrive. The best advice is to look back at the right time and start over.

Black bow

Blackfly is the most common pest and it damages plants by sucking up their juice. Crush these insects or spray them with organic insecticide.
