Rules for planting tomatoes
Tomato bushes of indeterminate type are enforced in the formation and tying. The cultivation of the variety "Japanese crab" involves the formation of a tomato bush in one or two stems with conducting pinching and tying (in conditions of proper agricultural technology and pinching, a tall variety is less susceptible to various diseases, including late blight).
One of the most important measures in the cultivation of large-fruited tomato Japanese crab is the timely and proper stepsonovki:
- when removing the stepson, you need to leave a small "stump", the length of which will be about a centimeter, which will prevent the rapid formation of a new additional shoot;
- the herding procedure is recommended in the morning, without simultaneously removing more than three to four additional shoots;
- to prevent damage to the tomato bush by a fungal infection, stepchildren should be broken off manually, and not trimmed with scissors or garden tools;
How to pinch tomatoes
- the most intensive development of stepsons is formed over the first flower brush, so it is very important to carry out their timely removal;
- in the process of pinching, it is advisable to remove the lower leaves in contact with the soil on tomato bushes;
- regular removal of stepchildren improves the illumination and purge of the tomato bush, which allows to accelerate the ripening of the fruit and reduces the risk of infection by a fungal or bacterial infection;
- pinching of the main stem on tall tomato plants is required to be carried out without fail, so that the fruits that are set have time to ripen before the onset of severe cold weather.
Of course, the variety with fruits of an amazing shape resembling a crab claw, and with very fleshy tasty pulp will not leave indifferent fans of large-fruited salad varieties and, subject to the cultivation technology, will allow to obtain high yields with minimal labor.
