If you have been growing fruit trees for some time , surely you have had very good harvests and others that have been rather poor . A small change in the crop can assure us that the production is going to be excellent, or on the contrary very bad.
It is a phenomenon known as vecería , and unfortunately practically all species of fruit trees can be affected.
- 1 What are the causes of vecería?
- 2 Can it be controlled?
What are the causes of vecería?
The vecería is a phenomenon that occurs because the plant, or some part of it, has lacked or has had something left over. Thus, the causes are the following :
- The tree has run out of reserves during the ripening of the fruits, therefore it will not be able to spend as much energy as it should on flowering.
- The fruits compete with the vegetative tips for nutrients; so that the development of the former is limited.
- Floral initiation, which normally occurs the year before flowering, interferes with tree growth.
It can be controlled?
Fortunately, yes, although it will depend on the species, variety, climate and location, among other factors, whether good results are achieved in that season or in the following ones. What is done is the following:
- Thinning of fruits : at the beginning of the development of the fruits, some of them or fruitful branches are removed. In this way, those that remain can mature without any problem.
- Striped : it is done mainly in citrus. It is a practice that consists of making a cut in the bark of the tree to temporarily prevent the descent of elaborated sap to the roots. This ensures that the growth of the fruits is optimal.
The vecería is a phenomenon that affects a wide variety of fruit trees: olive trees, acorn trees, citrus (lemon, orange, mandarin, etc.), among others. But as we have seen, with two simple methods it can be controlled
