Growing raspberries raises many controversial issues. Careless gardeners consider this plant so unpretentious that it allows it to grow literally as a weed. Caring owners, on the contrary, care about the issues of care, in particular, spring feeding. Do I need fertilizer raspberries in spring? How to feed the raspberries in the spring? What types of fertilizers to use, and in what quantity? It all depends on the conditions in which the crimson bushes grow, on their age and the type of soil. Naturally, the more fertile the soil, the better the crop you can collect.
Raspberry, really, is not among the too whimsical and demanding to care plants. But you can count on a good harvest only in one case: with a good feeding of the plantation.Tip! Fertilizers must be applied three times throughout the year: in spring, in summer (when the berries begin to ripen) and in the autumn period, when the formation of fruit buds takes place.
By the way, the last feeding of bushes is an investment in the next harvest.
Before and after landing
In order to get more berries in the first year after planting, it is necessary to feed them before planting the bushes. Novice gardeners are wondering: at what time is it best to plant raspberry bushes, in the fall or spring? In principle, both options have the right to life. The optimal time for planting depends on the region.
Autumn planting of bushes is preferable for the southern regions with mild winters. After the autumn planting, the seedlings safely overwinter, and in the spring the plants begin to grow vigorously.
For the Central zone and the northern regions, planting of seedlings in the spring is desirable, since the risk of freezing is large enough (especially if the winter is frosty and snowless), and spring bushes will take root without problems. The same applies to varieties with low winter hardiness (for example, black raspberry).
Preparation of beds
Site preparation for raspberry bushes begins with cleaning the soil from plant residues and carefully digging up (the depth of digging is 25-30 cm). It is necessary to take into account that raspberries are growing rapidly, therefore, the initially applied feeding may not be enough later.Tip! To avoid “starvation” of plants, fertilizers are applied around the perimeter of the site in advance, even during digging.
How to feed the plants depends on the preferences of the gardener and on his capabilities. Mineral substances and organic can be used as fertilizers. You can combine different types of fertilizers.
Here are a few options for complex dressings based on 1 square meter of land:
- Humus (6 kg), mineral mixtures with phosphates (80 g), potash fertilizers (25 g).
- A mixture of peat and compost (10-liter bucket), half a half liter cans of superphosphate and potassium salt.
If the land on the plot is fertile and was first used for growing garden plants, then a special top dressing of raspberries is not needed during spring planting. It is quite enough to use as fertilizer when digging up the soil of wood ash (1/2 kg per 1 "square"). The taste of the berries will be much better.
How to feed raspberries when planting
When rooting raspberries require a lot of nutrients, so fertilizing when planting raspberries need to be made directly into the hole.
Such fertilizers are added to each well.
- 2 tablespoons of superphosphate.
- A mixture of compost and humus, at the rate of 3.5-4 kg per square meter of land.
- Potassium salt (can be replaced with wood ash) - 2 tablespoons.
If the soil has an acidic reaction, then in addition to the specified list of fertilizers, 1 cup of hydrated lime should be added to the well.
Before adding fertilizer when planting in the hole, they need to be mixed with the soil. After the bushes have been planted, the ground around them should be mulched, using:
- Dry humus.
The first feeding raspberries
Proper feeding of bushes in the springtime is one of the main procedures that give the key to the abundant harvest of tasty and healthy berries. Fertilization in spring is April.
Before feeding the raspberry bushes, some preparation is required:
- Remove the branches, frozen during the winter.
- Collect the attacker with autumn foliage.
- If weeds have appeared, we must hand weed them before fertilizing the raspberries. Care must be taken not to damage the roots of the bushes.
- If the soil is well moistened, then in April nitrogen fertilizers should be applied as a first feed. The amount of fertilizer is about 80 g per 1 "square" of the bed.
- Peat, compost or rotted manure are used as mulch for bushes. This protects the soil from drying out. Manure attracts earthworms, which loosen the soil, providing air flow to the roots.
Spring dressing with organic
The use of organic fertilizers in the spring is an effective and environmentally friendly way of feeding.
It is possible to fertilize raspberries in spring in such ways:
- Dung diluted in water in a ratio of 1:10.
- Aqueous solution of bird droppings in the ratio of 1:20.
As mulch under raspberry bushes, you can apply bone meal.
Kemira uses good results (3 tablespoons per 10-liter bucket of water). For feeding 1 bush enough liter jars of solution.
Oddly enough, but as an organic fertilizer you can use weeds, or rather, an infusion of them. Comfrey and nettle are the most desirable option because they are rich in potassium and nitrogen.
Herbal infusion is prepared in this way. Pour 1 kg of the mixture of herbs with 10 liters of water and leave for 10 days, periodically stirring the mass. Adding a small amount of plants such as valerian or lemon balm improves the smell of top dressing. The resulting fertilizers for raspberries, dilute with water in a ratio of 1:10 - 1:15 and water the raspberry bushes at the rate of 2 liters per 1 bush.
Here are some top dressing tips from experienced gardeners:
- The best time to apply organic supplements is an overcast day.
- If the soil is dry, then you need to water the bushes before you feed.
- Do not allow the solution of organic matter on the leaves or stems.
- Prepare organic solutions for feeding in an open container. Fermentation processes are possible only with free access to air.
If you did everything correctly, then the harvest will turn out well: the berries will be large and sweet.
An important rule: overfeeding a plant is worse than underfeeding.
The cow and especially bird droppings are highly concentrated, so overfeeding can lead to undesirable consequences, including the death of plants.
Spring feeding with inorganic fertilizers
Potash, nitrogen salts and phosphates are necessarily necessary for the normal development of the plant. Sometimes potash fertilizers are replaced by ashes. Wood ash is beneficial in all respects. It is economically spent, does not contain harmful substances. The amount of ash per square meter of beds is about 150 g. It is possible to add ash in a dry form or mixed in water. In addition, ash neutralizes overly acidic soils.
Mineral fertilizers useful to feed the old bushes, before you begin to loosen the earth. Of the finished mineral mixtures, Azofosk, Kemira and Ekofosk have proven themselves the best. Mixes we breed according to the instruction, and then we feed up bushes.
As the first feeding, if there is no ready mix, you can use ammonium sulfate (15 g per square meter). Fertilizer is scattered under the plant, not dissolving in water.
From about the age of four, raspberries are fed with a mixture of mineral fertilizers and organic matter. Consumption per 1 square meter is.
- Potassium salt - 3 g.
- Nitrogen fertilizers - 3 g.
- Phosphates - 3 g.
- Humus - 1.5 kg.
Excellent as an integrated fertilizer and urea. On a ten-liter bucket there is 1 shovel of humus and a matchbox of urea. Top dressing is so strong and useful that it is enough for the entire growing season. It is even more useful to combine the use of the mixture with urea with mulching with sawdust, chopped straw or dry rotted manure.
If organic is not, then this recipe will do.
- Potash fertilizers - 40 g.
- Superphosphate - 60 g.
- Ammonium nitrate - 30 g.
These ingredients must be diluted before feeding in 10 liters of water.
Do not use potassium chloride for feeding raspberries: this substance can damage shrubs. And superphosphate is useful because it contains many useful elements: sulfur, magnesium and potassium.
We evaluate the appearance of the plant
According to experienced gardeners, the appearance of the plants helps to choose the best option for feeding. The appearance of crimson bushes can be judged on which substances it lacks, and which, on the contrary, too much.
- Nitrogen deficiency. The foliage on the bushes is small, faded.
- Large amount of nitrogen. Shoots and foliage grow too intensely, have a dark shade. The berries are showered immature, the harvest is significantly reduced.
- Not enough potassium. The foliage is colored at the edges in a brown color, resembles a scorched. Plants tolerate winter cold.
- Phosphorus deficiency. Bush gives weak shoots.
- Not enough magnesium. Bushes grow poorly, the leaves turn yellow from the center to the edges.
- Iron deficiency. The color of the leaves is unnaturally yellowish, with veins of green.
Spring feeding and subsequent fertilization throughout the year will allow you to get a good harvest of tasty and aromatic berries. Having identified signs of nutritional deficiencies in the plant's appearance, you can correct the situation, select suitable fertilizers and make the development of the plant more intense. Berries will be more aromatic, large and tasty.
