The green bean (Phaseolus vulgaris) is an annual plant of the family Fabaceae very easy to grow and produces abundantly. The ideal is therefore tostagger the seedlings to take advantage of staggered harvests. Review of details on the cultivation of green beans, a star of the vegetable garden without special requirements.
Sow the green bean
To sow this chilly, we must wait until the risk of frost is no longer to be feared and the earth has been sufficiently warmed by the spring sun so that it reaches a temperature of 10 to 12 ° C. Gardeners accustomed to growing green beans agree that the signal is given when the hawthorn blooms. In any case, you should know that the sowing period is between May and August, seed germination does not begin until the mercury is at least 16 ° C.
To speed up the emergence of green beans, there is a trick. It consists of leaving the seeds in the refrigerator for two to three months. before sowing time. After this time, the cold seeds should be placed in hot soil immediately. In this way, in a short week the young plants emerge from the ground whereas in normal times, they need a fortnight.
Used for many plant species, this procedure is called the cold lamination. It allows the seeds to be immersed in a state of dormancy for a period equivalent to a season, and this process ultimately only artificially reproduces winter conditions. It is then the heat, humidity and light that trigger germination. Some varieties are satisfied with a cold stratification of only two weeks.
Many gardeners simply place their bean seeds in the refrigerator for 15 to 21 days and then sow them immediately.
Sow in the ground
For some seedlings in pockets, we dig basins in the earth, 3 cm deep, and we deposit about 6 seeds which is then covered with a very thin layer of good soil. Care is taken to separate the pockets of about thirty centimeters from each other.
The semi online first requires the use of a serfouette (sometimes called the shelf) to perform the tracing of a furrow. We sow there one seed every 5 or 6 cm then we cover with a film of earth. You must have a very light hand because the seeds of green beans should not be buried much.
As soon as the seedlings have formed two leaves, it is necessary butter green beans. This consists of bringing earth to the foot of each plant.
Growing green beans
The green bean likes it in a well-drained soil But fresh and furniture. He can however be satisfied with a good garden soil, that is to say a topsoil. He likes sunny exposures because he is sensitive to cold.
It should be noted that fertilization is unnecessary for this vegetable. No need to add fertilizer during cultivation.
If you’re in a hurry, or just don’t want to take care of the seedlings, you can buy green bean plants in the garden center. Sold in buckets, they are ready to be transplanted, but it is not necessary to wait to put them in the ground.
Better do not sow all your seeds on the same day but rather space the seedlings in time and plant only a small amount of seeds at a time. This prevents all the beans from having to be harvested at the same time. If you want to enjoy fresh green beans throughout the summer, the seedling offset is really essential.
Caring for green beans
You don’t need to have extensive experience in this area to succeed in growing beans. It is also a real pleasure for novice gardeners who can produce their own green beans without complicating their lives.
Staking is only required for varieties of green beans with climbing habit, row beans, which can reach 5 meters in height. Makeshift stakes are quite suitable, such as a few straight bamboo branches, for example, or even a hazelnut tree. Care must be taken to install stakes before sowing.
You don’t have to spend your life with the hose or the watering can in your hand, because green beans are happy with fresh soil. He has not no need for a large amount of water. However, in summer, when the temperatures are high enough, it is necessary to water enough but without drowning the plants and taking care of do not wet the leaves. Watering at the neck is perfect for depositing water only at the foot of the plants.
Parasites and diseases
In the vegetable gardens of amateur gardeners, the green bean does not come under the onslaught ofno parasite in particular and is not susceptible to any disease because it is not cultivated intensively. The problem is different in green bean plantations as far as the eye can see where the seedling maggot can wreak havoc along with some fungal diseases.
It is best not to grow green beans in the same place every year. The ideal is to let pass at least two years during which it is possible to plant leeks, garlic, spring onion, onion, then the following year spinach, various varieties of salads and other leafy vegetables.
Harvest the green beans
Green beans offer very good yields. But they must be harvested as soon as they are good to eat. Some do not wait, having to be picked every two days, as is the case with fillet beans. The slightest delay is final: they take the lead! As for string beans and snap-it-all varieties, picking every 5 days is quite sufficient.
The ideal way to enjoy tasty and tender products is to consume them as the harvest progresses because they can only be kept for a very short time in the vegetable compartment of the refrigerator, three days at most. If the crops are more abundant than the needs of the family, then consider canning green beans. Their jaring requires sterilization for 90 minutes. You can also freeze raw green beans, which is amazingly simple.
