Why doesn't petunia bloom?
Petunia is one of the most popular flowers; they are grown both at home and in gardens at their summer cottages. Usually, petunia does not require much attention from the gardener, but this does not mean at all that you can not take care of the flower at all. And if it so happens that your petunia does not bloom, then at some point you made a mistake and violated the rules of agricultural technology. After reading this article, you can definitely answer the question "why does not petunia bloom?"
Why doesn't petunia bloom on the balcony? Pot size is one of the common reasons
Most often, flowering is delayed in indoor petunias that grow in pots. And this is due to the fact that the plant is simply cramped and lacks nutrients. Petunias have fairly strong roots and require a lot of space and ample soil.
Most likely you purchased small seedlings in pots with a diameter of 10-12 cm. And since petunia grows quite quickly, a pot with a volume of at least five liters will be most suitable for it.
In addition, the pots do not need to be placed close to each other, since in this case the plants do not have enough air and again it becomes cramped. If you are growing petunia in balcony boxesx and you do not have the opportunity to increase her "living space", then after the first wave of flowering, you can carefully cut the roots of the plant, cut the stem by about one third and plant in the same container, but in new soil.
After that, pour over with a growth stimulant. You can feed with nitrogen fertilizers for the speedy regrowth of foliage. And after a while, phosphorus and potassium for the best flowering. After this procedure, your petunia will bloom until the first frost.
Wrong watering regime
Too dry or, conversely, waterlogged soil can also delay flowering. Young petunia should be watered little by little, just enough to moisten the earthen lump. Older plants also need to be watered infrequently, but abundantly enough.
At home, it is possible to keep track of indoor petunias and adjust the watering regime. But in the country, where many of us come only for the weekend, you can install a homemade irrigation system.
To do this, dig in a 1.5-2-liter plastic bottle with the neck down next to the petunia bush, after cutting off the bottom of it, and fill it with water. The moisture will gradually go into the ground, and your plants will be absolutely comfortable.
Why petunia does not bloom: reasons. Lack of nutrients in the soil
Another reason for the delay in flowering may be a lack of nutrients, in particular potassium and phosphorus. Petunia, like any other plant, responds well to feeding. By the time of flowering, nitrogen-containing fertilizers can already be abandoned, giving preference to potassium-phosphorus fertilizers.
It is necessary to carry out top dressing as follows: water the soil a little, then water it under the root of the plant with a nutrient solution, and water it again with plain water. After that, you can additionally carry out foliar dressing by spraying the plants with preparations to improve the flowering of Agricola or Kemira Lux.
When choosing a fertilizer for your petunias, make sure that it also includes iron. This will protect the plants from the development of chlorosis (metabolic disorders in which the leaves turn yellow).
Lack of sunlight
All plants need adequate lighting for proper metabolism.But at the same time, some of them can grow in partial shade, and some in full shade. But petunia is not one of them, this plant loves the sun.
Lack of sufficient sunlight can also negatively affect flowering. If you are planting petunias in your garden, try to choose a sunny spot. If you grow them at home, then place the pot on the lightest windowsill.
The ideal air temperature for the comfortable growth of petunias is + 22 ... + 26 degrees. If petunia lives on your balcony and the nights become cold, then it is better to bring it into the house at night, so you will prolong the flowering.
Why doesn't petunia bloom? We form the bush correctly
In this case, we are not talking about giving the bush a certain shape, but only about timely sanitary pruning. You should remove any faded buds as soon as they begin to wither. If this is not done, then the bush directs all its forces to the maturation of the seeds and stops forming new buds.
If you plan to collect seeds to plant next year, then you can do this in the fall and it will be enough to leave 1-2 seed pods. Also, the timely removal of withered or dried leaves will facilitate the life of the plant and reduce the risk of developing any diseases.
If you pinch the top of a young petunia in a timely manner, then it will begin to grow wider, respectively, the flowering will be more abundant.
If you follow all the rules of agricultural technology, then most likely there will be no problems with the lack of petunia flowering. Petunia is very unpretentious, plant care in this case is reduced to almost a minimum. Pay attention to the plants and they will reward you with lush flowering.
