There is a lot of different information about fertilizers for flowers on the Internet. In principle, now and in stores there are a lot of various ready-made complex and specialized mixtures. Which one you need, choose based on the symptoms described in the article "When to fertilize flowers." And if you just want to feed a flower, it is enough to buy a complex fertilizer (either nitrogen-containing or phosphorous, depending on the needs of the flower).

How to fertilize flowers

So how to fertilize flowers? For example, complex mineral fertilizers contain not one, but several microelements: nitrogen, phosphorus, potassium and other elements. Depending on the type of plant for which they are intended, the elements are contained in different proportions. For decorative leafy plants - more nitrogen, for decorative flowering plants - phosphorus.

Most often, mineral fertilizers are sold in concentrated liquid form. It is necessary to bring them into the ground only in a 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 diluted with water (1.5 g per 1 liter of water) are used for feeding with potassium. Nitrogen fertilizers are obtained 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 dressings

No matter how many ready-made fertilizers appear in stores, there are persistent adherents of plant feeding with folk remedies.

So, the most effective fertilizer, in my opinion, is wood ash fertilizer. Before planting, it is mixed with soil in a ratio of 1:50 (1 ash, 50 soil). They also make a liquid top dressing: 25 g of ash (about 3 tablespoons) per 1 liter of water. Infuse for a week and then water.

Another type of top dressing and at the same time disinfection of the soil - a weak solution of potassium permanganate - is rarely used 1-2 times a year.

Also, many people use organic fertilizers. This is an infusion of bird droppings, manure, humus. These fertilizers are infused with water. Cow dung 1:10, poultry 1:25.

There are also such types of home fertilizers - water after defrosting meat and crushed eggshells. They have the right to live. But you need to make sure that unnecessary bacteria and insects do not get in the soil - since these fertilizers are a breeding ground not only for plants, but also for microbes.

Special reservations

The plant needs to be fertilized. But not always. When you can't fertilize a flower?

If the plant is sick, in case you recently planted it 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) apply top dressing.

For young plants, the fertilizer concentration is lower than for adults.

And most importantly, you need to remember that it is better to underfeed the plant than overfeed.

How and how to fertilize potatoes in spring, when planting in a hole, in summer and autumn, rules for preparing a potato bed

Fertilizers for potatoes when planted in a hole to increase the yield, we will consider which ones are better to apply in the spring and autumn to the soil in this article, because potatoes practically do not need additional fertilizers during the growing season.

Most of all, potatoes need fertilization during planting. The main substances are laid when planting tubers in the hole.

When to feed peppers

Pepper seedlings need nutrients from the start of growth for successful growth. It absorbs them through the soil.

Some gardeners prepare or acquire soil with all the nutrients and do not feed the seedlings. Others believe that it is impossible to grow healthy seedlings without additional fertilization.

Interesting! If you choose in advance the correct soil for seedlings of peppers and dive it into the soil saturated with nutrients, then fertilizing can be omitted until planting in a permanent place.

Many gardeners apply fertilizer if the seedlings look unhealthy, develop poorly, or stagnate.

A single application of fertilizer is recommended when there is a shortage of a certain nutrient.

There are 3 main components necessary for the full development of plants: nitrogen, phosphorus and potassium. They are all very important. With a lack of them, plants slow down growth, the leaves turn pale and a depressing appearance is observed. Therefore, you first need to determine which component is missing.

Table of Top Signs of Nutrient Deficiency

Important! The main thing is to add nutrients in the recommended dosages and not increase them.

Usually, to replenish the missing component, 1 additional feeding is carried out. With an overabundance of an element, you can harm the plant, which will negatively affect its health.

Advice! Substances are absorbed most quickly during foliar feeding.

Fertilizers for phlox

The composition of the substances with which you need to feed it depends on the stage of development of the culture. The phlox growing season consists of several stages:

  • height
  • development
  • bud formation
  • end of flowering
  • ripening of the seed pod.

For each phase of growth, you need to select the appropriate type of fertilizer:

  1. Organic. Natural nutrients containing nitrogen, thanks to which phlox grows well. Organic matter should be applied abundantly in the spring, and later, at the time of butanization, its amount is reduced.
  2. Mineral compositions. Chemicals that the plant needs during the summer and fall months. In the spring, urea can be used from minerals.
  3. Root dressing. The most effective care method used throughout the year. When organic matter and minerals are applied under the root of the bushes in a liquid or dry state. It is advisable to use these mixtures in early spring or during the autumn feeding of phlox and preparation for winter.
  4. Foliar dressing. Spraying bushes with nutrient compounds. The best time to spend is early June and late July.
  5. Folk remedies. In spring, wood ash is used, nettle infusion is used as an alternative to nitrogen sources, and bone meal is used instead of phosphorus preparations.

Fresh manure does not need to be applied under the plants, this can lead to rot and fungal diseases

What fertilizers do phloxes like?

Before feeding a crop, it is important to pay attention to the planting site. Plants planted in clay or infertile soil, in addition to complex fertilizers, like the introduction of humus, sand, peat into the ground.

From organic matter, flowers are well perceived:

  • slurry diluted with water in a ratio of 3:20
  • mullein in a rotted state, infused (1/3 of the substrate per 10 liters of water) and diluted 1: 3
  • bird manure, 1000 g per 10 liters.

Of the minerals, it is better to feed phlox:

  1. Crystalline urea, phosphorus, potassium, ammonium nitrate - can be applied only in spring.
  2. Potassium salt and potassium sulfate are indispensable in summer.
  3. Superphosphate - can be fed both in the spring and at the stage of fertilizing phlox for the winter.

Among folk remedies, it is better to give preference to wood ash, infusion of weeds, bone meal.

Wood ash will effectively protect phloxes from harmful insects

Signs of nutritional deficiencies

If phloxes lag behind in development, bloom poorly, shed their foliage ahead of time, it means that they lack nutrients. In this situation, it is important to correctly identify and eliminate the cause of the deterioration. The main signs of a lack of elements are:

  • phosphorus - late bloom, dull leaves of a dark green hue
  • potassium - poor flowering, pale color
  • nitrogen - developmental delay, pale leaves
  • iron - yellowing of foliage in spring and summer
  • copper - slow development, brown spots on the leaves
  • magnesium - falling of leaf plates.

Feeding technology

It is necessary to apply fertilizers in liquid or dry form in compliance with several rules. The soil must be well moistened. Otherwise, water with nutrients will either stay on the surface or be immediately removed by drainage. In order for the plant to assimilate the feeding through the roots, an even distribution of the entire mass over the soil is necessary.

When watering at the root, do not direct the stream of water directly to the stem. Active substances, even in small concentrations, can cause burns. Better to irrigate the land around. The root system of the cucumber is buried and branched, so all substances will enter the plant even in this case. Also, do not spray on the leaves those substances that are intended only for root application.

Fertilizers must not be applied before the first shoots appear. Even if seedlings are rare, too late, feeding will not speed up the process. It will be useless, but it can also damage the youngest processes that have not yet made their way to the surface.

All fertilizers to improve the soil must be applied when transplanting seedlings or before sowing. Deep loosening is unacceptable, this will cause damage to the roots. They use surface fertilizers that are similar to mulch in their properties. When watering, they will give nutrients to the soil and plant.

How and why to feed the plants on the site in August?

All plants on the site can be divided into several groups - vegetables, fruit trees, berry crops and shrubs. I would like to talk about fertilization in each direction separately.

  1. Fertilization of vegetable crops.Vegetables are annual plants that there is nothing to fertilize after harvest, which is why it is worth taking care of the soil where certain crops grew. Of course, if you have already successfully dug up the potatoes, then you can safely begin to dig up the area and apply fertilizers. Best of all is organic. It should be brought in during the autumn digging. Many experts are sure that early digging will help to better assimilate all the components and overheat in the soil, thereby saturating it as much as possible. But there is also an opposite weighty opinion that it is too early to dig up the plot in August, because the land will more than once get saturated with rains and turn into a paradise for weeds, and if the soil has also been fertilized, then by November only a clogged field of weeds will remain from your plot, which will have to dig up again. How to act is your business.
  2. Berry crops and shrubs.First of all, I would like to focus on strawberries. After all, it is she who should definitely be fed in August. A small digression, strawberries should be completely cut off after fruiting is complete, so that the old foliage affected by various diseases does not infect the soil, and new young bushes will fully form in August, so a young plant should be fed, and not old bushes. If you feed young shoots with nitrogen, then your foliage will grow much more before the first frost than in the season, and the harvest next season will be minimal. It is phosphorus and potassium that are responsible for fruiting, so the emphasis should be on these components. Also, we must not forget that potassium is responsible for the sweetness of the berries, so strawberries, just like raspberries, are recommended to be fed with potassium in August. Currants, gooseberries, raspberries need August feeding. As for the grapes, this procedure should be carried out after the completion of fruiting. If young varieties have already successfully hatched by August, they should also be fertilized.
  3. Fruit trees.Many are sure that trees are not vegetables, so why fertilize them, they say, there is no need for such procedures. It's a delusion. Everyone should saturate plants with useful components. Trees are no exception. Popular fruit trees - plums, pears and apple trees - enrich the fruits with sugar as much as possible in August, so potash complexes will be used in a timely manner. The rest of the fruit trees can be fed with organic matter or mineral complexes, where potassium and phosphorus prevail in percentage.


When making your own fertilizer, remember that orchids require more nitrogen than other houseplants. The substrate usually consists of bark. The bark is home to bacteria that consume a lot of nitrogen from fertilizers, leaving little for the flower itself. Therefore, the fertilizing agent should compensate for this.

Nitrogen must not be derived from urea. Fertilizers containing urea are suitable for common indoor plants with roots in the soil because urea is slowly broken down by bacteria in the soil, releasing nitrogen for the plants. Orchids are not grown in soil, urea is not destroyed, so nitrogen remains inaccessible to the plant.
