Tomatoes will not say directly what they lack, but they can send very legible signals. Just watch the plants carefully and react to them accordingly to enjoy a heavy, healthy yield for many weeks.
Tomatoes on hot days can temporarily wither because of strong sunlight. However, if their leaves do not rise even in the evening, it is a sign that the plant has stopped doing. The reason may be too dry earth, overheating roots or disorders in taking nutrients. In this situation, it is worth watering the plants in the morning or eveningavoiding soaking leaves. It will also be helpful to mulch the ground, which will stop moisture and protect the roots from peat. Tomatoes like heat, but temperatures exceeding 30 degrees Celsius are too much for them. Large then it costs to fight the effects of overheating and you must help them.
Cracked tomatoes are a common view after rapid changes in humidity. It happens sometimes after abundant watering after a long drought. The fruit skin does not keep up with a rapid growth of the pulp. To prevent this, water should be watered regularly, smaller portions. In turn, the drying of tomato flowers can be the result of overheating or lack of dust. In crops under cover, it is worth shaking them every few days to help pollen move. Drating flowers may also result from prolonged drought or fertilizer deficiencies. Tomatoes should always have moist soil, so water them every two days in hot weather.

If the tomato does not tie the fruit despite the flowering, it may be too high nitrogen concentration in the soil. The plant then “goes into the leaf”, but not in crop. You need a correction of fertilization of less nitrogen, and more potassium and phosphorus. Pale green leaves with yellow discoloration are a symptom of magnesium or iron deficiency. In this case, it is worth reaching for foliar spraying with microelements or natural preparations, such as a manure of comfrey or spraying of wood ash.

The bottom leaves of tomatoes yellowing with time are nothing disturbing. This is due to the aging of the plant. All you have to do then is to break them so that they do not constitute a load and a seed of diseases for the plant. However, if, despite watering and fertilizing, the tomato leaves turn yellow and browning, a sign that they were attacked by fungal diseases. This happens often if we forget about crop rotation. Disease pathogens are found in the soil and get into the plant through the root system. They inhibit the flow of nutrients. Unfortunately, this situation is irreversible. There is no way to save infected tomatoes. All you can do is break out infected plants so that the diseases do not move to other copies. Do not throw their leftovers to the compost, but get rid of them from the garden.
