Petunia is a beautifully flowering plant that is often found in gardens, front gardens, balconies and windowsills. She decorates the walls of buildings, planted in vertical beds and flower beds, in flowerpots and pots.

Many budding gardeners grow petunias. Yes, it only happens that instead of an airy beautiful colored cloud, a small stalk with a couple of flowers sticks out. And here it is worth considering why petunia does not bloom. How to feed petunia at home? How to prolong the flowering of petunias? What top dressing should I use for flowering petunias?

Top dressing is, of course, wonderful, but first of all we must remember that it is necessary to surround the plant with care, choose the right place with good lighting and ensure timely watering. Only if the growing conditions are observed will fertilizers be beneficial. Don't forget the golden rules:

  • It is better to under-supply than to pass.
  • During a certain period of the growing season, the plant needs specific substances, therefore there are no universal dressings.

Fertilizer types for petunias

Petunias need fertilizers throughout the season, which are divided into two categories:

  • basic;
  • additional.

Basic, also called, compulsory feeding include:

  1. Nitrogenous substances. Nitrogen is needed for better leaf formation. It must be introduced at the beginning of plant formation and shoot growth.
  2. Phosphorus-containing substances. Without phosphorus, it is impossible to build up the root system, as well as the formation of flowers, therefore such fertilizers are applied later than nitrogenous ones.
  3. Potassium supplements. Without potassium, there will be no lush flowering of plants.

Additional dressings include those that increase seed germination, protect against fungal diseases, and, thanks to vitamin supplements, improve the condition of petunias.

Important! When growing petunias on a balcony in a container using soil rich in nitrogen, potassium and phosphorus, special fertilizers can be omitted. It is possible that the plants will have enough of their content in the soil.

When to fertilize

It is important to carefully choose a scheme for applying dressings, while observing the growth of plants and the type of flower development.

  • Potassium nitrate is used to make the plant grow strong and healthy.
  • For better formation of shoots and flowers, fertilizers are used, in which the ratio of nitrogen and phosphorus is 2k1 ("Flower").
  • Phosphorus-containing drugs are useful after a pick (Monophosphate or Crystalon).
  • From the beginning of July, nitrogen is added again (10 g of urea per 10 l of water). You can also use a diluted mullein infusion.

How to feed when landing

How to feed hydrangea for abundant flowering

The first time you need to fertilize petunia before sowing seeds. You can add special dry granules to the soil so that when watering they dissolve and give up their nutrients. But, using this method, it is easy to make a mistake, perhaps there was enough of this or that substance in the soil, and with an uncontrolled intake, there will be an excess of some trace elements or a lack of others.

Important! Pelleted seeds purchased in specialized stores do not need stimulants. But it is useful to treat lagging seedlings with succinic acid.

Succinic acid is a good fertilizer.It is poured with a solution on the dried soil in which the seeds were planted. This top dressing will be a good stimulant, and also the formation of buds will increase with its application.

We must be prepared for the fact that petunias will have to be fed for lush flowering throughout the season.

After about two and a half weeks, the first balanced fertilizing with nitrogen-containing fertilizers is made for better leaf growth. Also at this time it is necessary to treat petunias with a solution of fungicides to prevent fungal diseases. Potassium permanganate can perfectly replace fungicide.

Top dressing when diving

After another couple of weeks, the seedlings are dived and planted in separate pots. At this time, the plant receives severe stress. To facilitate adaptation to a new environment, it must be watered with yellow crystal, the solution of which has a positive effect on the growth of the root system, thereby the seedlings will take root faster and better in a new place.

Mineral fertilizer

Exactly the same feeding is done when petunias are planted in open ground.

How to feed petunia for abundant flowering

And now, the seedlings are planted outside, the bushes have collected a sufficient number of leaves, it is time to apply fertilizers for better flower formation. These can be:

  • Plantom S;
  • Pink crystal;
  • Boron;
  • Scots.

These fertilizers increase the formation of new flower buds and accelerate the onset of flowering.

Also petunias respond with good flowering to:

  • Garden of Miracles;
  • Master;
  • Kemira Lux;
  • Uniflor Bud.

    Uniflor bud

These solutions are intended for root feeding. For foliar top dressing, you can use the drug Plantofol, which needs to be sprayed with a flower bush.

If the flowers grow on poor soil, the following fertilizers can be applied:

  • Carbide;
  • Urea;
  • Potassium humate;
  • Magnesium;
  • Potassium or ammonium nitrate.

How can you fertilize petunia for abundant flowering:

  • Kemira Lux, containing all macr-o and microelements required for plants. Their ratio is optimally balanced and has an easily accessible form for plants. After using this drug, the formation of buds and the growth of new shoots are improved. Flowers, having blossomed, will bloom longer. Moreover, the color of leaves and buds will be brighter and more saturated. It also increases the resistance of petunias to disease.

    Kemira Lux

  • Agricola 7 is a special fertilizer that is used for flowers. It contains 20% nitrogen, which has a beneficial effect on plant growth, 10% phosphorus, for better flower formation. It can be used not only for root feeding, but also for foliar feeding too. With this method of processing, all useful substances are easily absorbed by the plant - leaves and shoots, due to which the result will be faster than from root feeding.

Important! When preparing the solution, attention must be paid to ensure that the dry substance is completely dissolved in water. Otherwise, the plant may get burned.

It is customary to use any of these fertilizers once a week, but experienced flower growers recommend applying them in 2-3 days, and some generally say that they "feed" their petunias in this way with each watering, only you need to make a weaker solution, weaker than usual in 3-4 times. Although, as you know, how many people, so many opinions. You need to choose the best option yourself and monitor the condition of the flowers.

Important! It must be remembered that the amount of fertilizer should "grow" with the plant. That is, the older the petunia, the more fertilizer it needs. During flowering, the plant requires 2 times more feeding than during the period of growing leaves.

Folk remedies

Feeding with yeast

How to feed gladioli for abundant flowering

The people have a saying "It grows by leaps and bounds." There is a grain of truth in this expression. Gardeners use yeast mash to feed various berry and vegetable and flower crops, including petunias. Feeding from yeast stimulates plant growth well, strengthens them. You can water the plant with a mash, or you can fertilize it on a leaf.If foliar dressing is used, the solution must be made to a lower concentration.

Feeding chicken droppings

The nutrients (nitrogen-potash) found in chicken manure are very important for petunias. It is best to apply a manure solution when planting seedlings in the ground.

Lemon acid

With the help of citric acid, you can remove yellowness from the leaves. For this, 10 g of acid is dissolved in 10 l of water. The plant is treated with this solution from a spray bottle.

Lemon acid

Ash

Another folk remedy for adding potassium and phosphorus. In addition, ash fights some diseases.

How to prolong the flowering of petunias

How to feed dahlias for abundant flowering

At the end of August, many flowers that have bloomed all summer are already slowly reducing the abundance of flowering. But petunia, with proper care, can bloom for a long time (up to the very frost) and delight with its beauty. To do this, she needs to provide enough sunlight and good watering. In order for these flowers to bush more strongly, it is necessary to regularly pinch the upper shoot. In this case, there will be even more side shoots and, accordingly, flowers. You can generally rejuvenate the bush a couple of times in a season, cutting it off strongly. After pruning, it is useful to fertilize the plant with herbal infusion for faster growth of greenery.

Important! If, from the moment of planting, regular fertilizing of the plant has been carried out, you cannot stop. If you stop fertilizing, flowering will decrease.

It is necessary to constantly remove faded flowers. If you leave the seed pods, the plant spends all its energy on ripening the seeds, flowering in this case will be poor. You need to properly care for the petunia. Water, fertilize, pinch it in time. And then it will bloom very magnificently and will bloom all summer and autumn.

Having studied the tips on what petunia is fed with, it will not be difficult to achieve abundant flowering, pleasing to the eye.
