Top dressing of seedlings - when and how to apply fertilizers, their composition


Many indoor plant lovers grow their pets themselves, because it is not always possible to find the right houseplant in the store. In addition, buying flower seeds will be much cheaper than an adult plant. But all this is not so important. The main thing is what a fascinating process it is - growing an indoor flower! And what a pity it is when the seedlings of a flower die. Having lost my seedlings of indoor plants several times, I decided to approach the issue of growing it more responsibly. As it turned out, during cultivation is of great importance proper feeding of seedlings.

What elements are needed to feed seedlings

If the condition of the plant does not cause alarm, you can use universal fertilizers for feeding. Actually, the main elements that are necessary for the growth and development of a plant are nitrogen, phosphorus and potassium. It is good to feed young seedlings with a mixture with a predominance of nitrogen salts.

But there are situations when you need to know which microelements your seedlings lack. This can be understood by her appearance.

Lack of nitrogen leads to a slowdown in plant growth, the leaves become small and pale. The stems of such a plant are thin, weakly branching.

Lack of phosphorus. Plant growth is significantly delayed. Plants become weak, leaves turn yellow at the edges and fall off. Disease resistance and cold hardiness of seedlings are reduced.

Lack of potassium. In addition, the growth of plants slows down, their resistance to fungal diseases decreases. The edges and tops of the leaves turn brown and die off.

Lack of calcium leads to the death of young leaves and tops of the stems, weakening the growth and development of roots. First, young leaves acquire a light color, then light yellow spots appear on them. The edges of the leaves bend down and they fall off.

Lack of magnesium. The leaves of the plant become "marble", spotty, turn pale between the veins. Gradually they turn yellow, curl and fall off. The growth and development of the plant slows down.

A lack of boron leads to a stop in the growth of stems, roots, and the death of the apical point of growth. Young leaves become dark in color, their edges are bent down. The shoots of the plant become brittle.

For feeding with nitrogen, ammonium, salts of nitric and nitrous acids are used. With a shortage of potassium, potassium nitric and phosphate is used. The plant can obtain the required phosphorus from mixtures containing phosphoric acid salts or superphosphate.

Basic feeding rules

Having correctly chosen the necessary fertilizer, you still need to competently feed the seedlings. Let's learn how to do it competently.

It is recommended to feed seedlings every 7-10 days. Seedlings are fed only during the growth period. Plants that are not yet rooted should not be fed.

It is best to feed early in the morning on a sunny day, but never feed the plants in hot weather. It is very important that the fertilizer does not get on the leaves and stems, as this can burn the plant.

To feed seedlings, you should take fertilizer with a reduced concentration. Commercially available mixtures are used as top dressing. The bags indicate for which plants and in what quantities they are needed.

A few hours before feeding, the seedlings are well watered. This protects the roots from scalding and contributes to the uniform saturation of the entire clod of earth with the fertilizer. But remember that over-fertilization is detrimental to plant development.

Also, I learned that it is very good to alternate fertilizing with mineral fertilizers and biofertilizers with growth stimulants based on humic acids.

As you can see it is not at all difficult to make the correct feeding of the seedlings... A competent approach, a little work - and your reward will be a beautiful houseplant grown by your own hands.

How to feed fruit trees and shrubs in spring

Top dressing of trees and shrubs in spring is the most important stage of care, on which the decorative qualities of plants, their growth and the amount of harvest depend. Perennial plants greatly deplete the soil, because from year to year they require nutrition. That is why it is important to fertilize the garden with special means several times a season. Adequate nutrition is the key to abundant flowering, dense ovary and a generous harvest. In addition, regular feeding minimizes the risk of infection of trees and shrubs and is responsible for their health. For the first time a year, the garden is fertilized in early spring, then fertilizing is continued at regular intervals.

An approximate fertilization calendar for fruit and berry crops will be offered in this article. Here you can find out about the rates of fertilization, find recommendations on how to better feed certain fruit trees and shrubs in the spring.

The choice of fertilizer for seedlings

Fertilizer release form for seedlings

Nothing more effective and more convenient than liquid feeding has not yet been invented for seedlings. Therefore, we choose either liquid or instant granules, tablets, powders. We are interested in precisely those fertilizers that are specially produced for liquid fertilizing and are not applied in dry form. If it is a powder or granules, then their consumption is small, and they are produced in small sachets.

Fertilizer composition: what should be in fertilizer for seedlings

Fertilizer for seedlings must include: nitrogen (N), potassium (K), phosphorus (P or P2O5), meso- and microelements (magnesium, iron, boron, zinc and others).

Trace elements are needed in chelated, not sulfate form. Sulfates are not suitable for feeding seedlings: in solution, they decompose into ions with an electric charge and therefore are easily bound by soil particles. Firstly, this makes them less accessible to plants, and secondly, accumulating in a small volume of soil, metal ions from useful elements turn into poison. The manufacturer does not always indicate the form of trace elements on the package, but usually chelates are still added to the fertilizer. If there is no exact information, just in case, make sure at least that the packaging does not have the word "sulfate" or chemical formulas ending with "SO4".

Fertilizer dosage for seedlings

Be sure to see how the grower recommends applying fertilizer to seedlings. General rule: the concentration should be 2 times lower than when feeding plants in the garden. If the same doses are recommended, this should be alarming - it is possible that the fertilizer is obviously a dummy, from which there will be neither harm nor benefit.

Depending on the composition of the fertilizer, its consumption may vary, but on average for seedlings it is approximately 7-10 g (tablespoon) of dry fertilizer per 10 liters of water. For liquid fertilizers, it is more difficult to check how adequate the manufacturer's recommended application rate is.

Fertika Universal-2 Spring Summer: application and application rates

For those who have never used the universal mineral fertilizer Fertika garden and vegetable garden Spring Summer, we will describe in detail how to apply it. Read the application rates carefully to avoid overdosing.

When to apply

We advise you to carefully read when to introduce into the soil and feed vegetables, flowers, berry bushes, fruit trees with granular fertilizer Fertika Universal JSC Spring Summer:

  1. Mix with the earth during the digging of the soil in the garden in the spring the whole norm of granules... You will not need to feed the plants more during the season.
  2. Mix with soil and sprinkle granules into furrows or holes before sowing seeds or planting seedlings... We advise you to use half the dose, and divide the remaining part in half for feeding in the summer. Feed the first time two weeks after planting seedlings or seedlings, and then after another 2 weeks.
  3. If the granules were not introduced into the soil during digging, during sowing or planting seedlings, divide the fertilizer dose by 3 times... That is, scatter a third of the norm and mix with the ground about two to three weeks after germination or planting of seedlings, and then two more times every 2 weeks.
  4. Perennials, shrubs and trees are best fed in that the nutrients begin to take effect as early as possible.
  5. Plants that grow in the garden and vegetable garden on poor soil, the universal Fertik is fed 2 times per season. The first time in the spring, the full dose is applied, and the second time in the summer - half of the norm indicated for a particular culture.
  6. In the rainy season it is recommended to add half of the pellet norm in the summer, as the nutrients are washed out.

Instructions for use

The granules of the universal Fertika for the garden and vegetable garden are not dissolved in water. They are dug up in the spring together with the ground or scattered in the aisles of vegetables, greenery, flowers and along the near-trunk circle of shrubs and trees. Then it is mixed with soil.

In the beds between the rows of vegetable, green, flower crops, we recommend mixing the granules with the ground using a caparula. For mixing with soil in the trunk circle, it is better to take a rake or a small shovel. Perform the procedure carefully so as not to damage the roots.

Application rates of Fertik Universal-2 granules in tablespoons

On the package with Fertika Universal-2 fertilizer Spring Summer, the application rate per square meter is written in grams. This is not very convenient. We will write how many tablespoons of granules should be scattered per 1 sq. M. beds or trunk circle. Based on the calculation that one spoon without a top contains 17 grams of granular fertilizer.

For one square meter you will need:

  • 2.5-3.5 tablespoons for feeding raspberries, any currants and other berry bushes
  • 1 tbsp. add a spoon with a slide between the strawberry bushes
  • 4-5 st. l. scatter granules over the near-trunk circle of mature fruit-bearing trees and 2 times less around young trees
  • Stir 4-5.5 tablespoons of granules with soil in flower beds with annual, perennial flowers and roses
  • 3.5-4.5 st. l. - for feeding sweet peppers, tomatoes, potatoes
  • 4.5-5.5 spoons - for growing greens and legumes
  • 5.5 - 6 tablespoons per 1 sq. m. will be needed for feeding onions and root crops (beets, carrots, turnips)
  • from 6 to 9 tbsp. l. apply to grow cabbage, cucumber, pumpkin, melons, celery, rhubarb and grass on lawns.

According to the reviews of many gardeners and gardeners, the granular mineral fertilizer Fertika Universal-2 JSC Spring Summer is very good. It is the best suited for feeding any plants in the garden and vegetable garden in the spring and summer. After using it, you will not have to think about how to fertilize vegetables, flowers, shrubs and trees so that they grow well and give a crop.

Mineral fertilizers for vegetable seedlings

As the name implies, mineral fertilizers consist of the substances necessary for the plant - nitrogen, phosphorus and calcium. Most often, the required element is contained in one fertilizer, although you can also find top dressing with the necessary doses of nutrients - complex fertilizers for seedlings... What fertilizers are considered mineral?

  • Ammonia sulfur, urea, ammonium sulphate, ammonia water - contain nitrogen.
  • Superphosphate - contains phosphorus
  • Potassium chloride, potassium salt - contains potassium

By the way, the content of the necessary elements in these fertilizers, as a rule, does not exceed 40%. The fact is that the substances needed by plants are already contained in the soil, but they can be washed out with rains. Therefore, feeding plants with such substances is vital. The main advantages of mineral fertilizers are as follows:

  • Improves soil fertility
  • Forms humus

At the same time, it is important to strictly monitor the dosage of drugs, otherwise, instead of improving plant growth, you can get an unexpected result. By the way, this view fertilizers for flower seedlings recommended as the most effective. Fertilizers of mineral origin are often mixed with organic ones. So, you can add Eurostim fertilizing - it consists of natural antidotes, trace elements and humic acids, and works well in the autumn. The organo-mineral fertilizer "Dobrodiy", which includes all the substances necessary for the full development of plants, has also proven itself well.

Organic fertilizers for vegetable seedlings

Unlike mineral fertilizers, which have gained not very good fame due to agronomists' fears about the "unnaturalness" of the grown plants, liquid fertilizers for seedlings have always enjoyed great success. Organic fertilizing is represented by three types of fertilizers: manure, droppings and compost. All these substances are of natural origin and have the best effect on the development of plants. Moreover, this is exactly what fertilizer for seedlings at home is the least expensive, so that farmers with even a small number of animals and their own yard can always use the waste to feed the plants. Unlike mineral fertilizers, organic matter contains a larger complex of elements necessary for the plant - in addition to potassium, phosphorus and nitrogen, such fertilizers also contain copper, boron, manganese, cobalt and other minerals. Let's consider the main advantages of using different types of organic feeding.

How to understand that plants need ash

The three main beneficial components of ash are calcium, potassium and magnesium. The use of ash in the garden is justified only in the case of a lack of these substances in the soil, because excess fertilizer applied without measure can harm the plants. How to track it down?

Signs of a lack of batteries
Potassium deformation and chlorosis (depigmentation) of leaves, dropping of flowers, ovaries and buds, dark spots on fruits, dying off of the upper part of the shoots and cessation of plant growth
Calcium and magnesium leaves wither, curl up into a tube, their edges dry out, roses stop smelling
Signs of excess batteries
Potassium sharp discoloration to pale green, and then loss of foliage, browning of the flesh of pears and apples
Calcium loss of leaves, death of shoots, overgrowth of leaf rosettes, chlorosis
Magnesium dying off of roots and, as a consequence, the inability to absorb calcium

Top dressing of a flower garden in spring

Caring for perennial flowers in spring begins as soon as the snow melts in the flower beds. After the traditional harvesting of plant residues, it is worth taking care of those who will delight you with flowering all season or some period of it.

Bulbous plants (muscari, hyacinths, crocuses, tulips, iridodictiums, etc.) are usually the first to wake up in the garden. Although it may seem that they have accumulated everything they need for full flowering over the past season, it is worth feeding them so that next year they will also enjoy lush buds.

Feeding of primroses is carried out together with loosening and mulching, choosing complex mineral fertilizers for this. Application rates depend on the variety of colors.

Flower Fertilizer Application rates Terms of introduction
Hyacinths Nitrophoska and urea 2 tbsp for 1 sq.m After sprouting
Crocuses Potassium sulfate and superphosphate 20 g per 1 sq. After the leaves sprout
Muscari Urea, superphosphate, potassium sulfate 5 g of each substance per 10 l of water After the buds appear
Tulips Kemira Universal, Kemira Flower 1 tbsp for 10 liters of water After emergence and after the appearance of the third leaf
Daffodils Nitroammofoska 30 g per 1 sq. M The first time - after germination, the second - after the appearance of the peduncle
Primroses Kemira Universal, Kemira Flower 1 tbsp for 10 liters of water After bud formation

Many gardeners are also wondering how to feed roses in the garden in spring.It is worth remembering that roses need phosphorus for abundant flowering, but they just cannot do it. Young bushes growing branches and greenery prefer organic feeding. For them, spring application of humus or a weak solution of manure, chicken droppings, infusion of weeds will be optimal. In order not to burn the plants, fresh droppings must be diluted 1:20, left for 5 days, diluted again 1: 3, and only after watering. Overripe manure can be diluted 1:10, insisted for a week, then diluted 1: 2 and used.

Adult rose bushes prefer ammonium nitrate to organic matter. It is scattered over the flowerbed immediately after the snow melts at the rate of 20-30 g per 1 sq. M. May also stimulates flowering, prepared from 10 g of superphosphate and 10 g of potassium sulfate per 10 liters of water.

Fertilizer for other garden flowers in the spring can be selected universal. Complex mineral fertilizers, capable of saturating the soil in a flower garden with the required amount of nitrogen, phosphorus, potassium and trace elements, will cope with this task best of all. You can give preference to solutions prepared on the basis of Kemira, Agricola-Aqua, etc.

In addition, you can saturate the soil in stages, first adding nitrogen fertilizer (ammonium nitrate, urea or urea) under the flowers, and adding the remaining necessary components as the plants grow.

All plants on your site are different, but each of them requires spring feeding for a good, active season. Do not deprive any corner of timely care and enjoy the results throughout the warm period.
