About fertilizers for flowers on the Internet there is a lot of different information. In principle, now and in stores there are a lot of different ready-made complex and specialized mixtures. Which one you need, choose, focusing on the symptoms described in the article "When to fertilize flowers." And if you just want to feed a flower, just buy a complex fertilizer (either nitrogen-containing or phosphorus - depending on the needs of the flower).
How to fertilize flowers
So what to fertilize flowers with ? For example, complex mineral fertilizers contain not one, but several trace elements: nitrogen, phosphorus, potassium and other elements. Depending on what kind of plants they are intended elements are contained in different proportions. For decorative deciduous - more nitrogen, for decorative flowering - phosphorus.
Most often, mineral fertilizers are sold in concentrated liquid form. Make them into the ground only in diluted form. The proportions are individual for each fertilizer and are indicated on the package.
If you prepare fertilizers yourself, then potassium sulfate, potassium chloride or potassium salt in dilution with water (1.5 g per 1 liter of water) is used to feed potassium. We obtain nitrogen fertilizers from urea , ammonium nitrate or ammonium sulfate (1 g per liter of water). Phosphate fertilizers are made from dry superphosphate (1 part per 30 parts of soil or 6 g per 1 liter of water).
Home and folk dressing
No matter how much it appears in the stores of finished fertilizers, there are staunch adherents of fertilizing plants with folk remedies.
So, in my opinion, the most effective fertilizer is wood ash. Before planting it is mixed with soil in a proportion of 1:50 (1 ash, 50 soil). Also do liquid top dressing: 25 g of ash (about 3 tablespoons) per 1 liter of water. Insist a week, and then water.
Another type of top dressing and soil disinfection at the same time - a weak solution of potassium permanganate - is rarely used 1-2 times a year.
Also many who apply organic fertilizers. This is an infusion of bird droppings, manure, humus. These fertilizers are infused with water. Cow dung 1:10, bird 1:25.
There are still such types of home fertilizers - water after thawing meat and crushed egg shells. They have the right to life. But you need to make sure that unnecessary bacteria and insects are not found in the soil - since these fertilizers are a nutrient medium not only for plants, but also for microbes.
The plant needs to be fertilized. But not always. When is it impossible to fertilize a flower ?
If the plant is sick, if you have recently planted or transplanted it, if the plant is young. It is also not recommended to feed flowers in hot weather - fertilizer can burn the root system. Also, if the earthen lump has dried up, first you need to water the flower well, and only then (after a few hours) make top dressing.
For young plants, the concentration of fertilizer is lower than for adults.
And most importantly, you need to remember that it is better to underfeed the plant than to overfeed.
