How to feed raspberries during the ripening of berries, flowering and fruiting

Raspberry bushes bear fruit well even with little care. However, without a sufficient amount of nutrients, the fruiting of the crop may deteriorate. Therefore, before planting bushes in the garden, you need to figure out how you can feed raspberries during the ripening of berries.

Symptoms of nutrient deficiency

Lack of one or another nutrient is accompanied by pronounced symptoms. It is recommended that you familiarize yourself with common signs of nutritional deficiencies.

Nitrogen

Some gardeners forget to fertilize raspberry seedlings with nitrogen fertilizers. The main symptoms of a lack of this substance include:

• delayed development of planted seedlings;
• each leaf is covered with brown or yellowish spots;
• deteriorating yields;
• chlorosis leaf plate.

Phosphorus

Each large bush that has begun to bear fruit must be periodically fertilized with phosphorus compounds. If this is not done, the surface of the leaves will turn blue, purple or red. The development of the root system will also worsen, which will lead to a deterioration in fruit growth. In some bushes that lack phosphorus, stems and flowers are deformed.

Potassium

Complex feeding composition must necessarily contain potassium components.If there is too little potassium in the soil, the raspberry leaves will gradually turn yellow. Also, a potassium deficiency negatively affects fruiting and impairs the taste of ripe berries.

Magnesium

Every agronomist knows that raspberry bushes need magnesium fertilizers. Without magnesium, leaf necrosis develops, accompanied by yellowing and death of the leaves. Also, due to the lack of magnesium, the ripening of the crop slows down.

Calcium

Experienced gardeners recommend periodically feeding planted bushes with calcium fertilizers. In plants that lack calcium, young leaves sag and wither. Fruit spotting and poor yields indicate calcium deficiency.

Copper

In order for raspberries to grow and bear fruit normally, it is recommended to add more copper sulfate to the soil. Due to the lack of copper, young foliage brightens, and the old one becomes covered with yellow spots.Plants that are rarely fertilized with copper fertilizers are poorly protected from fungal diseases.

What kind of fertilizer do raspberries like

In order to harvest a tasty and juicy harvest in the future, you need to figure out what fertilizers raspberry bushes need.

Mineral fertilizers

Most often in the summer, a plot with berries is fertilized with mineral top dressing. Gardeners advise adding fertilizer mixtures in July, when the berries begin to ripen.

People who want a sweet harvest should add more potassium s alt with superphosphate to the soil. Such top dressing will save the fruit from a sour taste. Also, wood ash is introduced into the soil, which contains elements that promote the growth of planted bushes. 200-300 grams of wood ash is consumed per square meter.

Organic top dressing

Spring is the right time to use organics. It contains most of the trace elements that can accelerate the growth of shrubs and improve their fruiting.

Among the most effective organic supplements are:

• Decomposed manure. Feed mixtures prepared from manure enhance the immunity of seedlings and warm the root system. In order for top dressing to give a positive result, each bush is fed with six kilograms of manure.
• Compost. Composting is carried out to disinfect the soil and saturate it with nutrients. Rotten vegetable waste and fallen leaves are used to make compost.

Nitrogen fertilizers

If the remontant raspberry bush suffers from a lack of nitrogen, the plants are fertilized with nitrogen-containing dressings. Common nitrogen supplements include:

• Bird droppings. People who have been growing raspberries for many years are advised to regularly fertilize them with bird droppings. At the same time, they should not be used too often, since top dressing from the litter has an increased level of toxicity.
• Amide compounds. Calcium cyanamide, urea or formaldehyde are used to saturate the soil with nitrogen.

Folk recipes

Before you start fertilizing raspberry seedlings, you need to familiarize yourself with the recipes for preparing feed mixtures.

Ash

June is a good month for applying mixtures made from wood ash. Such fertilizers are used when plants lack phosphorus or potassium.

To make a feeding liquid, 250 grams of ash is poured into a bucket of water. Then everything is thoroughly mixed and filtered with gauze. It is necessary to water the seedlings with diluted ash 3-4 times a month. In this case, the solution must be carefully poured under the root so that it does not fall on the leaf plate and stems.

Potato Peels

When raspberry fruit set slows down, it is recommended to use formulations made from potato skins.

Before preparing top dressing, all potato peels will have to be dried. To do this, they are laid out on a heated battery or placed in the oven for 1-2 minutes. Then the dried potato skins are placed in a wooden barrel and filled with cold water. Potato peel is soaked for 3-4 days, after which it can be abundantly poured over the bushes.

Yeast

Some gardeners use yeast as fertilizer. To prepare a yeast feed composition, use:

• Yeast powder. When creating a means for watering bushes, 150 grams of powder are poured into ten liters of heated liquid. After 20-30 minutes, the resulting mass is mixed with 40-50 liters of water and infused for 3-4 hours.
• Raw yeast. This recipe is used when the raspberries start to grow slowly. A kilogram of the product is mixed with 7-8 liters of water and left to ferment for 10-11 hours. After that, the starter is added to a 50-liter barrel of water.

Kora

A good feeding composition can be prepared from rotted twigs and tree bark. Most often, gardeners choose autumn to add such dressings, since during this period raspberries often lack nutrients.

To fertilize the soil, a mulch layer from the bark of coniferous trees is laid out near each shrub. The laid wood is removed in early spring, when the snow melts.

Chicken manure

The end of spring is the time when plants need nitrogen supplements. So that the berry does not need nitrogen, feeding compounds from chicken manure are regularly added to the soil. The main advice to follow when using fertilizer is not to add fresh manure. It must be mixed with water so that the composition does not damage the bushes. To do this, add 200-350 grams of litter to a ten-liter container with water.

Ways to feed bushes

Before you start planting raspberries, you need to familiarize yourself with the basic methods of fertilizing. Feeding raspberries during flowering and fruiting is carried out in two main ways.

Foliar

Gardeners recommend foliar feeding of shrubs so that they quickly appear ovaries and ripen berries. When using this technique, the plant will absorb the nutrients not only by the horse system, but also by the leaves.

As foliar fertilizers, mixtures prepared on the basis of boric acid, copper sulphate or superphosphate are used. From time to time, the bushes are sprayed with a composition of wood ash.

Under the root

Summer is the period when raspberries finish flowering and the period of berry ripening begins. In order for the plant to always have enough nutrients, in the summer part of the fertilizer is applied under the root.The first top dressing is added in a complex to the soil in June. For this, liquid mixtures are prepared, which include potassium sulfate, superphosphate and urea.

Recommended timing of fertilization (table)

To figure out when to feed the berries in the summer or autumn, you need to familiarize yourself with the exact timing of adding dressing compositions.

Spring

Most gardeners advise using mineral and organic fertilizers in the spring. The spring fertilizing schedule begins when the weather gets warmer and the snow completely melts.

What to consider when feeding raspberries

To ensure proper care for raspberries, you need to familiarize yourself with the features of top dressing at various stages of growing bushes.

During flowering

When the bushes begin to bloom, they must be heavily fertilized, as this results in an increase in yield.It is necessary to use a mixture that consists of 200 grams of mullein, 150 grams of ash with urea and ten liters of water. All ingredients are mixed, after which each bush is watered with the composition.

During the fruiting period

In order for the fruit to ripen faster and be larger, it is necessary to feed the seedlings until the end of fruiting. When the pouring of raspberries begins, slurry is applied. It is mixed with warm water in a ratio of one to four.

To increase the efficiency of the mixture, you can add ash with superphosphate and urea to it. The fertilizer is poured into shallow grooves made near each bush.

After suffering illnesses

Any disease causes the bushes to weaken and gradually dry out. Therefore, it is recommended to saturate the area where the berries are grown with top dressings.

Mullein and potassium-phosphorus compounds are used to restore immunity. Also, manure is added to the ground in the amount of 5-8 kilograms per square meter.

After harvest

When the collection of ripe raspberry berries is over, a small top dressing of the bushes is carried out. Before the beginning of autumn, citric acid is used as a fertilizer. Gardeners also advise adding 1-2 kilograms of rotted compost for each bush. To protect the root system from the autumn cold, the soil is mulched with a peat layer 8-10 centimeters in height.

What to feed if the leaves turn yellow

When the bushes get sick or attacked by a pest, the leaves begin to turn yellow. You can get rid of yellowing with the help of fungicidal agents, which include Topaz, Hom and Fitosporin. In the spring, plants are treated with Bordeaux mixture or ammonium sulfate solution.

To increase the yield

If raspberries bring a small crop, you need to think about improving its yield. Some people think that only transplanting helps to improve fruiting, but this is not so. You can increase the yield with some top dressing.

Experienced gardeners recommend feeding shrubs more often with chicken manure mixed with manure and compost.

After transplant

After replanting, bushes weaken and therefore need to be fed. In order for the plant to have enough nitrogen, potassium and phosphorus, compost is added to the soil. You can also use ammonia mixed with water and manure, or a boric compound.

Features of fertilizing remontant and grafted raspberries

Now a lot of gardeners grow grafted or remontant raspberries on plots. Feeding such plants is carried out in the autumn, before the cold snap. Urea is added to the soil with fresh manure, which in winter will warm the root system and protect it from freezing.

If there is no manure, mineral supplements, bird droppings or s altpeter are used instead. All these components will saturate the soil with the elements that are needed for the normal development of raspberry seedlings.

In the spring they use herbal infusions mixed with phosphorus-potassium mixtures. These substances contribute to the formation of fruit buds.

Conclusion

It is difficult to find a gardener who does not like to grow raspberry bushes in the garden. Before planting such berries, you need to familiarize yourself with the main types of fertilizers that are used when feeding planted raspberries.
