How and what to feed remontant raspberries in July

Remontant raspberry varieties are becoming more and more popular every year. Summer residents are attracted by the yield, the ability of shrubs to bear fruit several times a season, and the variety of varieties. Caring for remontant raspberries differs in many ways from caring for ordinary raspberries, especially when it comes to fertilizing. In this article we will look in detail at how to fertilize shrubs in order to get a tasty harvest.

What feeding does remontant raspberry need in July?

Varieties of remontant raspberries bear fruit several times a year, so shrub care gardeners pay special attention. In July, most varieties The fruiting period begins - raspberries need mineral fertilizers (potassium, nitrogen, phosphorus).

They are applied by root and foliar methods. Mineral fertilizers stimulate fruiting, improve the quality of fruits, and serve as a preventative against diseases and pests.

Symptoms of deficiency

You can determine which microelements raspberries lack by their appearance. When there is a deficiency of substances, spots and dots appear on the bushes, shoots dry out, leaves curl and fall off:

• light green wilted leaves indicate a lack of nitrogen;
• curly and darkened - raspberries lack potassium;
• thin and brittle shoots - phosphorus deficiency;
• yellowness of leaves and small brown dots - lack of boron;
• a change in the color of the veins on the leaves indicates iron deficiency;
• deformation of berries and discoloration of leaves - lack of manganese.

A deficiency of microelements is dangerous because raspberries' immunity is weakened, and the plant is more susceptible to diseases and insect pests. Many gardeners think that raspberries are an unpretentious plant that does not need feeding. This is a misconception, especially when it comes to remontant varieties.

Deadlines for fertilizing in July

The timing of fertilization depends on fruiting. Feeding raspberries 2-3 weeks before picking berries. For example, if raspberries bear fruit after July 20, then fertilizers are applied at the beginning of the month. Warm and windless days are chosen for the procedure. The right time is morning or evening.

It is not recommended to fertilize raspberries in hot weather - sunburn is possible.

Favorable days

Some summer residents, when choosing the date of fertilizers, rely on the lunar calendar. In 2020, July 1-3, 9-11 are chosen for organic fertilizing, and July 24-26, 28-30 for mineral fertilizing..

It is believed that on these days, fertilizing will be better absorbed by the plant and will give good results. Do not fertilize raspberries on July 15-17.

How to feed remontant raspberries in July

Mineral, organic and folk remedies are used for feeding. When applying them, it is important to observe the dosage and precautions.

Organic fertilizers

Organic fertilizers increase the resistance of remontant raspberries to diseases and pests and stimulate fruiting. They also nourish the soil, so they are especially necessary in regions with weak and poor soil. The first organic fertilizing is carried out in the spring, the second - at the end of July or beginning of August.

Fertilizer options:

1. Infusion of rotted manure. 5 kg of horse or cow manure is placed in a deep container and filled with 15 liters of water. Place in a dark place for a week, stirring occasionally.Then dilute with water in a ratio of 1:10. Apply under the bush early in the morning, per 1 square meter. m takes about 10 liters of solution. Fresh manure is not used - it provokes chemical burns of the roots.
   

   Herbal infusion
2. Herbal infusion. The advantages of fertilizer are not only efficiency, but also availability. For preparation, use fresh nettle and chamomile. 1 kg of grass is crushed and 4 liters of water are poured. Stir and leave in the sun for 5 days. The resulting infusion is diluted with water in a ratio of 1:5. The product is used for irrigation.
3. Infusion of chicken manure. 1 liter of litter is diluted in 30 liters of water and left for 3-4 days. Fertilizing enriches the soil with nitrogen, magnesium, calcium, zinc, and strengthens the plant’s immunity. Apply fertilizer to moist soil, avoiding contact with leaves and shoots.

Before fertilizing, weeds are removed from the ground - they take away nutrients from the raspberries.

Weeds are pulled out by hand so as not to damage the raspberry root system - it is located close to the soil surface. It will be useful to loosen the soil to a depth of 5 cm so that the fertilizer penetrates to the roots.

Mineral fertilizers

Mineral fertilizers are responsible for the taste and presentation of berries. Urea is used for feeding - per 1 sq. m requires 10 g of substance. Urea enriches the soil with nitrogen and stimulates the development of shoots. Ammonium sulfate is also useful - per 1 sq. m leaves th st. l. Mineral fertilizers are not combined with each other; this can lead to an excess of microelements.

A convenient way to add mineral supplements is to use ready-made complex preparations. They contain microelements that are balanced according to your needs. remontant raspberries.

Effective fertilizers - “Zdraven”, “Kemira”, “Gumi-Omi”. They increase productivity, stimulate raspberry resistance to frost, and the berries grow large and sweet. Ready-made fertilizers are sold in liquid, dry, and granular forms. When applying, it is recommended to carefully read the preparation instructions and safety rules.

Folk remedies

Folk remedies cannot replace mineral or organic fertilizers. Summer residents use them as a supplement. Such products prevent the development of diseases and pests and are harmless to human health and the environment:

1. Wood infusion ash. Pour 100 g of ash into 10 liters of water and stir. Without waiting for it to settle, water the bush. It is recommended to use fresh ash obtained from the combustion of birch or pine firewood. The infusion is rich in macro- and microelements, normalizes soil acidity, and makes the soil more nutritious.
   

   Onion peel infusion
2. Banana peel infusion. 10 pieces. soak in 10 liters of water and leave for a week in a warm place. Pour the infusion over the raspberries at the root, after loosening the soil. The infusion is rich in potassium, which increases the frost resistance of raspberries and prepares the plant for autumn.
3. Infusion of onion peels and laundry soap. Pour 50 g of husk into 8 liters of warm water and leave for 3 days. Before watering, add 50 g of grated laundry soap and apply under the root. An infusion of onion peels protects raspberries from insect pests.

How to apply fertilizer correctly

There are root and foliar feedings. The first ones are applied at the root using a dry or liquid method, the second ones are sprayed on the shoots and leaves.

Root method

Root fertilizers are applied into grooves dug in a circle at a distance of 0.5 m from the bush. One plant requires 3-4 grooves. Fertilizers are better dissolved and absorbed in a liquid medium, so before the procedure, raspberries are watered generously with warm water.

The optimal air temperature is from +10°C to +25°C. At high temperatures, fertilizing is not absorbed and causes plant burns. If dry fertilizer is applied to the roots, then it is not just scattered near the raspberries, but covered with your hands. When applied superficially, microelements do not have the desired effect.

Foliar method

Foliar fertilizers are aimed at replenishing micronutrient deficiencies and protecting raspberries from diseases and pests. Spray raspberries in the morning or evening; the weather should be dry and windless.

Summer residents recommend processing the leaf on both sides and carefully lifting the shoots with your hands. For spraying, use a spray bottle. Before pouring the product, it is treated with a solution of potassium permanganate. After each use, the spray bottle is washed and re-disinfected.

Attention! For successful fruiting, summer residents alternate foliar and root fertilizers. The interval between procedures is 10-14 days.

Feeding during flowering/fruiting

During flowering remontant raspberry needs complex feeding. They influence both the development of shoots and fruit set. Summer residents use Bona Forte berry fertilizer. It contains nitrogen, phosphorus, potassium, sulfur, zinc, molybdenum, copper. Dilute 2 tbsp in 10 liters of water. l. and mix. Apply by root method at the rate of 3-5 liters per 1 square meter. m. The fertilizer is sold in granules, is easily absorbed by raspberries of any age, and quickly dissolves in water.

During fruiting, double superphosphate is added - 15 substances per 1 square meter. m. A folk remedy, a yeast solution, will help supplement the effect of fertilizing.Dissolve 10 g of dry yeast, 5 tbsp in 10 liters of water. l. Sahara. The ingredients are stirred and left for 2 hours. The infusion is diluted with water at the rate of 1:5. The solution is applied into the grooves - 7 liters per bush. A boric solution will also help increase the yield of raspberries - 2 g of powdered boric acid is diluted in 10 liters of water.

Advice from experienced gardeners

To ensure that feeding remontant raspberries in the summer is effective, experienced summer residents share their recommendations and advice:

1. Before fertilizing, gardeners prune shoots older than 3 years. They require a lot of nutrition, but produce few berries. It is recommended to leave only one- and two-year-old shoots. Prune raspberries according to the standard pattern using garden pruners.
2. If it is not possible to feed the raspberries in July, the procedure is postponed to the end of June. The main thing is that the weather is suitable.
3. Do not water the plant with liquid fertilizers on dry soil. Such fertilizing will burn the soil and have a bad effect on yields.
4. If you don’t have scales at hand, a matchbox will help determine the accuracy of fertilizer application. It includes 13 g of urea or 10 g of wood ash, 17 g of ammonium nitrate or 22 g of viburnum salt.
5. Prepare infusions in clean and disinfected containers. Place out of the reach of children.

Conclusion

For summer feeding of remontant raspberries, mineral, organic and folk remedies are used. Mineral fertilizers include urea, ammonium sulfate, and complex preparations. From organic - infusion of mullein, herbs or chicken droppings.

Among the folk remedies, an infusion of banana peel, yeast or ash is noted. Apply fertilizers to moist and weed-free soil. Before the procedure, gardeners recommend pre-watering the soil and cutting off shoots older than 3 years.
