To grow tomatoes in greenhouses is much more difficult than in the open ground. Grades are very demanding of care, it is necessary to closely monitor the temperature and humidity. Accordingly, we must remember the main signs of "tomato" ailments.
Tomatoes growing in a greenhouse and in the open ground can be twisted. Twisting occurs for various reasons.
May curl up "boat". This happens from overheating and low humidity. It is necessary to frequently watered, sprayed on the foliage Immunotsitofitom, airing teplichku.
Something similar happens in poor root development and an excess of phosphorus. Treat as needed.
Leaves may curl at the top, "in a ram's horn." This happens when the plants "zhiruyut". Tomatoes will leave in the tops due to the excess nitrogen. Perhaps the reason - in the high humidity and the addition of fresh manure, but not humus.
When twisted in the daytime and at night straightened - blame the overheating, it is necessary to arrange ventilation of the greenhouse during the day. If not - it is in an excess of nitrogen, stop watering for a week; teplichku not ventilate to temperature readings increased.
If the leaves are not twisted, but are directed upwards at a right angle - it is also not good. This happens when the ground is too dry and hot in the greenhouse, and it is not aired. Culture will be bad fruit, showering flowers, ovary and small fruits.
What is the treatment?
The need for timely watering and airing!
When the fruit in a large brush and ripe, and on the other - are small and do not grow, remove the tomatoes from the first brush, a week does not remove the leaves and stepchildren. It also requires a decrease in temperature of up to sixteen or eighteen degrees Celsius. If this is not done, the upper tomatoes are quite small.
Tomatoes with edges - a sign of sorts. It can be exacerbated when the temperature readings in teplichke and outdoor low. You can change the grade or increase the temperature, tempering seedlings.
Cracks on tomatoes. Many and uneven watering, for example - at first did not water a long time, then poured, tomatoes and cracked. Perhaps the reason is high humidity.
Double flowers - "Sunflowers". When fused 2-3 and more flowers. These flowers are the varieties with large fruits. Tomatoes grow big, but ribbed curves. Sunflower can be formed only on the first brush. Remove them.
Spots on tomatoes - palely green, yellow. Where spots - kozhurki becomes solid. Perhaps it burns from the sun when the sun is too warm flank pomidoriny or do not have enough potassium. Potassium can help to fertilize; Ventilate the greenhouse and lower the temperature in it.
Burn from the sun is characterized by the fact that tomatoes are formed whitish, as if fading spots. Get help to fertilize with nitrogen before flowering period.
Small, underdeveloped or hollow tomatoes. Poorly pollinated. In greenhouses burns can occur often due to their lack of wind. Every day it is necessary to shake the trellis. In an open ground - due to the hot temperatures (greater than thirty-four degrees Celsius). Pour culture to refresh.
