Petunia is a popular indoor and garden plant. It is unpretentious and looks very nice in the garden on a bed and on a balcony in a pot. But it happens that petunia does not bloom. Why this happens, what to do - let's talk about it later.
Pot
The most common problems with flowering occur in flowers in pots. And the simplest explanation for this is the lack of strength to grow. This plant has a strong and extensive root system, and it needs a large amount of land for normal growth. 
For the cultivation of a single flower optimally suitable capacity of about 5-8 liters. And the distance between the pots should be decent - so that the flowers do not overwhelm each other.
Did you know? Petunia belongs to the family Solanaceae, that is, is a relative of tomatoes and potatoes.If the petunia grows on the balcony and there is no possibility to put a large capacity for it, then there is the option of growing with pruning and replanting.
To do this, after the end of the first wave of flowering, petunia is taken from the pot, the roots are cut, the stem is cut to one third and planted in a new ground. 
Best of all - in a new big pot. But if the size of the roots allows, then you can leave it in the old. Watered and sprayed with growth enhancers (Epin, Zircon). It will be good to add nitrogen fertilizers for the growth of green mass, and before flowering - potash and phosphate.
It will be useful for you to learn how to feed petunia for abundant flowering.Thanks to this procedure, the petunia will bloom a second time and its bloom will last until October.
Watering
Another answer to the question of why petunia does not bloom is dry ground, and this is due to improper watering. 
Young flowers should be watered rarely; they do not like abundant moisture. For adult plants, abundant but not frequent watering is beneficial. Therefore, it may be possible that your plants do not get enough moisture (or vice versa, a lot of moisture), so they refuse to bloom.
Important! If you do not have the opportunity to regularly water the flowers - dig a plastic water bottle near them. One such "auto drinker" is enough for 6-7 days.
Top dressing
Petunia may also lack fertilizer for flowering.
These flowers love feeding and respond well to them. For active growth, use nitrogen, and potassium and phosphorus - this is just what you need to fertilize the petunias, and then water them so that they bloom profusely. The scheme is as follows:
- watering;
- root dressing;
- watering;
- top dressing on leaves.
Important! The complex must include iron. This element will prevent the development of chlorosis.
Lighting
Petunias love fresh air and sunshine. Therefore, it is difficult to get a good flowering at home. 
Pick a place to grow flowers so that they receive plenty of heat and light. For example, it may be a balcony or a flower bed facing south. The optimum temperature for them is 23-25 ° C. If it is cold at night, the pots should be brought into the house.

Shaping and trimming
Problems with flowering may also be due to the untimely cleansing of plants from old shoots and peduncles. 
Watch this. Remove old shoots. Fade flower stalks remove immediately after withering. Leaving the old flowers, you provoke the development of seeds, and the plant will throw all the forces on the formation of seed pods.
Cleaning fallen and wilted foliage in the lower part of flowers will save them from the development of diseases and the appearance of pests.
Did you know? If a young flower is removed to the top (growth point), then this will give an impetus to the development of the plant in width, not up.
As you can see, the main reasons for the lack of flowering are pretty simple. And everything is in a small amount of attention and care. Do not let everything take its course, be attentive to your pets - and they will answer you with their beautiful flowers.
