Grow green beans in pots

Green beans are a legume tasty and with excellent nutritional characteristics, food rich in proteins, minerals and vitamins. We are used to considering them as a vegetable in its own right from the botanical point of view, it is in all respects beans, even if it is a particular variety of the "mangiatutto" type.

We have already talked about the cultivation of green beans in the field, but you don't necessarily need to have a piece of land available: you can easily grow this plant on your own balcony, directly in pot. Let's now go into how to do it in the best way and while remaining within the perspective of organic farming.

Green beans and beans are as we have said the same leguminous plant, the phaseolus vulgaris, a very resistant crop, provided that it is not subjected to large changes in temperature and that it does not suffer frosts. What characterizes the green beans is the fact that they have smaller seeds than the classic beans and a tender pod, also edible and pleasant to eat. The green bean is then collected and cooked in its entirety instead of shelling the seeds.

Choose the type of plant

To put green beans on the balcony, first of all we need to choose the type of plant we want to sow, they count different varieties of this legume, characterized by different sizes and also colors of the pod. The main difference, however, which interests us primarily for the purpose of choice, is that of dwarf and climbing beans.

  • THE dwarf green beans complete their crop cycle in less than 60 days and they do not need supports and tutors for growth, which occurs mostly superficially to the ground.
  • The climbing green bean instead it needs to 90 days from sowing to harvest and needs stakes, it is also characterized by its much higher productivity than the dwarf variety.

So if we have more time and more space (a slightly larger pot, vertical space for the supports) we can opt for creepers, while for a simple and less demanding cultivation, even on the balcony, we will opt for the dwarf variety. In any case, the green bean, whatever it is, remains a good choice for the balcony garden.

Suitable location and period of cultivation

What we have seen for the pot cultivation of the bean also applies to the green bean: these are plants that love balance, so in order not to compromise the harvest and growth, we will avoid both frosts and extreme heat. The best time to grow them in pots is from March until June, we will also be able to sow several plants a few weeks apart so as to have a staggered crop available.

The green bean plant it needs sun, therefore we prefer a position well exposed and perhaps protected from the cold north winds. If the summer is particularly hot, it will be good to protect the plant with shading sheets that cover it from the sun during the hours when it is higher.

The cultivation of the green bean is similar to that of the pot bean, which we have already talked about in Orto Da Coltivare.

Choose the right pot and soil

There choice of vase will determine the success of our cultivation, we prefer a pot of at least 35-40 cm in diameter and sufficiently deep.
At the base of the pot we place pebbles, gravel or shards to facilitate the drainage of the water, then fill it with simple universal soil, perhaps enriched with a little homemade compost.

If you want to further enrich the soil you can put a sprinkling of wood ash, being careful to use it as necessary, so as not to tire the plant and have effects opposite to those desired.

Sow the green bean

The best way to sow green beans is directly on the ground, making a small 2-3 cm hole in the center of the pot, next to which we will place our eventual support on which to make the plant climb.

A good technique can beimmersion of the seed in warm water for a whole day and then place it in the ground, but not covering it too much: as the peasants sayings remind us that the bean must hear the bells. Depending on our choice on the type of plant, we will have our harvest from 50 to 90 days from sowing, a good idea is sowing climbing plants every 20 days.

Plant tutors

Fantasy is the only limit in choosing the best support for our green bean plants, we can use from bamboo canes to simple poles plastic or wood or choose networks.

Since these are potted crops, ideal for our terraces or balconies, we could choose to place the legumes near the railings and not use external stakes.

Irrigation and adversity

The green bean plant does not require excessive water, but it is very important constancy and verify that the soil is always kept humid. Water stagnations, on the other hand, can weaken the green bean and should be avoided as much as frosts, since environmental factors together with the quality of the soil could allow some problems and disturbances such as mold or rust.

For plants as well as for humans, the idea must prevail that prevention it is the way forward, creating favorable conditions for health rather than having to intervene with a posteriori treatments.
