Top dressing of roses in spring for flowering is carried out several times - after the snow melts, then during the blooming of the first flowers and before the formation of buds. For this, organic, mineral and complex compounds are used. It is desirable to alternate them, but the dosage cannot be violated.

Why do you need to fertilize roses in spring

Spring feeding of roses with organic, complex and mineral fertilizers is very important. During this period, the plants come out of dormancy and begin to gain green mass. To speed up this process, in the spring, the soil must be enriched with useful microelements that perform important functions:

  1. Nitrogen is part of the proteins that ensure rapid cell division and plant development. It is nitrogen that promotes growth processes, therefore it is a vital element for roses and other crops.
  2. Phosphorus promotes lush and abundant flowering, the formation of peduncles, buds and petals.
  3. Potassium provides plant immunity to adverse weather conditions, diseases and pests. This element also regulates the exchange of water in the tissues of the rose.
  4. Magnesium is another essential trace mineral found in many spring rose fertilizers. It ensures the normal formation of flower buds.

Timely fertilization creates conditions for lush flowering and increases plant immunity

In the spring, roses in the garden should be fed with nitrogen and phosphorus compounds. After winter, the plants are weakened, and the soil needs to be restored. Many useful compounds are washed out in spring by melt water. The soil is getting poorer.

Terms of spring fertilization of roses

Fertilizing roses in the country after winter begins in the spring, namely in March or April. The exact time depends on the weather conditions in the region.

Important! It is necessary to wait until the snow completely melts so that the melt water is absorbed, and the soil has time to dry out a little.

Otherwise, the fertilizer will wash away, and you will have to re-fertilize the roses.

The main terms of introduction by region:

  • south - end of March;
  • middle band - early April;
  • Northwest - middle of the month;
  • Urals, Siberia, the Far East - before the May holidays.

Fertilizers are applied several times (depending on the type and variety of roses):

  1. The first top dressing is immediately after the snow melts or when planting.
  2. The second is when the first leaves begin to bloom.
  3. Then they are fed every two weeks until the buds begin to form, after which the procedure is stopped until summer.

Important! It is better to apply spring fertilizer for roses on a warm day, when the air has time to warm up to + 7–8 ° C. If the weather is cool, then it is advisable to postpone feeding.

The first fertilization is applied at the end of March or at the beginning of April.

Rules for feeding roses

Nutrient mixtures can be applied both root and foliar. In the first case, the resulting solution is poured directly under the root, without touching the green part of the plant. An alternative option is to seal the complex fertilizer granules into the trunk circle. In the second case, the liquid is poured into a spray container and the stems and leaves of the rose are sprayed.

Foliar dressing

You can feed roses in the spring after winter by foliar method. In this case, beneficial substances immediately enter the plant through the surface of the leaves and stems. They are absorbed much faster and have an effect after a few days. The timing and composition of fertilizers for roses in this case will be the same as with the root method. Procedure rules:

  1. The concentration is always reduced by at least 2 times compared to root application. Too concentrated a solution will burn the leaves, which will negatively affect the roses.
  2. Spraying roses in spring is carried out only in warm, dry and calm weather. Otherwise, useful components will be washed away along with sediments.
  3. It is advisable to start spraying early in the morning or late in the evening so that the sun's rays do not burn the green part of the rose.
  4. It is necessary to feed roses by foliar method not in early spring, but 2-3 weeks later than the standard period. The air should warm up to 12-15 ° C. Plants by this time will form young leaves, through the surface of which substances will pass into the tissues.
  5. If using organic mixtures, it is important to filter the solution through a fine sieve or cheesecloth to remove large particles.

Fertilizing at the root

You can apply root fertilizers under roses in spring in two ways:

  1. Dilute the solution and water the plant at the root.
  2. Spread granules (for example, azofoski) in the trunk circle or cover up wood ash together with the soil.

In the first case, the dry drug is dissolved in water, observing the dosage and safety rules, after which watering is carried out directly under the root, without getting on the green parts of the plant. First, you need to make a small depression in the trunk circle, which is especially important if the rose grows on a hill. Weather conditions and time do not really matter, the main thing is that the day is without rain.

In the second case, it is necessary to make an annular groove around the central shoot, for example, within a radius of 15 cm, then lay the granules and cover them with earth. Another way is to embed fertilizer directly into the planting hole (when planting).

Granular substances are scattered in the trunk circle, observing the dosage

How and how to feed roses in spring for lush flowering in the open field

Gardeners use organic, mineral, complex fertilizers, as well as folk remedies. The composition of feeding roses in spring for flowering may be different. It is not necessary to apply all mixtures at once. You can choose only 2-3 options and apply them in accordance with the instructions.

Organic fertilizers

Organic fertilizers are absorbed by plants much slower than mineral fertilizers, since they go through a long stage of processing by soil bacteria. However, these dressings work for a long time. They perfectly enrich the composition of the soil due to the active reproduction of beneficial microorganisms.


This compound is highly soluble in water and is largely absorbed by roses. It does not cause burns and gives relatively quick results. Therefore, experienced and novice growers often choose urea (carbamide) as the first feeding of roses in early spring. It contributes to the rapid growth of green mass, and also protects plants from the negative effects of recurrent frosts. Dosage - 15 g per 1 m2.

Chicken infusion

For cooking, take chicken manure and dilute with water in a ratio of 1:20. Then it is infused for 5-7 days, after which it is diluted 3 times more and watering is started.

Important! If chicken manure is old, it can be used in a more concentrated form - diluted with water in a ratio of 1:10, and then - 1: 2.

Chicken infusion is a great source of nitrogen and other nutrients

Cow infusion (mullein)

A solution of manure is also prepared by diluting with water in a ratio of 1:10. Then they insist for one week (preferably in the shade). Then again it is diluted 2 times and the rose bushes are watered.

Mineral fertilizers

Inorganic compounds dissolve well in water and are quickly absorbed by plants. They are often used in the spring. The most popular mineral fertilizers: ammonium nitrate, superphosphate, potassium salt.

Ammonium nitrate

This is the first spring feeding, which is characterized by a high concentration of nitrogen, which allows the plant to quickly exit the period of winter dormancy. Application rate - no more than 25 g per 10 liters. This volume is enough for processing 1 m2 or 1 adult bush.


Introduce before the beginning of the formation of buds. If the superphosphate is double, it is used in the amount of 7-8 g per plant, if simple - 15-16 g. Usually this composition is combined with potassium salt.

Potassium salt

This is potassium chloride, i.e. potassium chloride, which is extracted from a mineral called sylvin. Contains up to 20% sodium chloride (table salt) and up to 3% magnesium chloride. Application rate - no more than 20 g per 1 plant.

Ready complex fertilizers

Fertilizing roses in spring for better flowering can be done with ready-made formulations, which contain all the necessary elements (nitrogen, phosphorus and potassium). These include the following drugs:

  1. Azofoska - this fertilizer for roses, which is applied in spring, also has another name: nitroammofoska. Mixture composition: nitrogen (N), phosphorus (P) and potassium (K). The ratio depends on the type of fertilizer. It is applied in the spring in April or early June before the first blooming of the buds. Norm - 30-40 g per 1 m2.
  2. Ammofoska - the composition also contains nitrogen, potassium and phosphorus in the same ratio. Along with them, there are other trace elements in the mixture - sulfur and magnesium. Norm - 3-4 g per 1 m2.
  3. Potassium nitrate - a composition with a maximum content of potassium and nitrogen (up to 99.8%). Stimulates the development of the rose and helps to strengthen its immunity. Dosage in spring - 15 g per 1 m2.
  4. "Biomaster" - along with nitrogen, phosphorus and potassium, humates are present in the composition of this fertilizer for roses. These are organic salts that help to strengthen the immune system, lush flowering and rapid plant growth. The dosage is about the same - 15-20 g per 1 m2.

Azofoska and other complex fertilizers contain all the essential macronutrients for a rose

Folk remedies

Even if there is no ready-made composition at hand, you can make it yourself. For example, ordinary weeds or ash left after burning wood and branches are suitable for this.

Green manure

If weeds have already appeared on the site, they can be mowed at the root (before the formation of seeds), chopped into small pieces, tamped and filled with water in a ratio of 1: 1. The mixture is infused in the shade for 7-10 days, after which it is filtered and diluted 10 times.

Wood ash

The composition obtained from burning firewood, branches, tops and other plant residues contains:

  • phosphorus;
  • potassium;
  • calcium;
  • chlorine;
  • magnesium;
  • sulfur;
  • sodium;
  • silicon.

Therefore, wood ash is widely used as fertilizer in spring, summer and even autumn. It is sealed when planting - 50-70 g per well or when digging up the soil - 200 g per 1 m2... Also, ash can be diluted in a bucket of water (30 g per 10 l) and applied in the spring by root method.


Another effective top dressing that stimulates the growth of beneficial bacteria in the soil. It is introduced in the spring by dissolving 20 g of dry or ordinary yeast in 2 liters of warm water along with 2 tbsp. l. Sahara. The mixture is infused overnight, after which it is diluted with water 10 times.

Onion peel

In the spring it serves not only as a top dressing, but also as an effective means of protecting against pests. Dry husks are collected from the onion, crushed, 100 g are measured and 2 liters of water are poured, allowed to boil for 15 minutes. After that, it is diluted 5 times, i.e. bring the total volume to 10 liters, filter and water the flowers.

Onion peel decoction protects roses from pests


Feeding flowers in spring is a mandatory procedure. However, it must be carried out with caution - sometimes excessive feeding leads to the opposite effect. Therefore, it is worth paying attention to a few simple rules for spring processing and fertilization for roses:

  1. It is important to water the soil well before root dressing, as the concentrated formulation can burn the roots. This is especially important in the case of pellets that are embedded in the trunk circle.
  2. It is important to have time to give fertilizing for roses in the spring. Wait until the snow melts completely and the air warms up to 8–10 ° C and above during the day. It is undesirable to fertilize plants during flowering.
  3. Young roses do not need feeding during the first year. Fertilizers are desirable to close up even when digging up the soil in the fall, for example, add humus in the amount of 3-7 kg per 1 m2 (depending on the natural level of fertility).
  4. When preparing a solution, one should be guided by the amount that can be spent at a time. Liquid cannot be stored for a long time. If we are talking about foliar feeding, then the solution should only be fresh.
  5. In the spring, nitrogen compounds are necessarily used. Inorganic nitrogen (for example, ammonium nitrate) is more suitable for pruned adult roses, while organic nitrogen (urea) is more suitable for young shrubs under the age of 4-5 years.
  6. Fertilizers should be alternated.


Feeding roses in spring for flowering is quite simple. The main condition is to carefully observe the terms and rates of application. In the spring, it is enough to feed the roses 2 times with the root method and carry out 1 foliar treatment. This will ensure rapid growth and lush flowering of the plant.
