Autumn feeding raspberries


The period of fruiting pulls out a large amount of nutrients from raspberry bushes. If you do not take any measures to restore the balance of the soil, then in the coming year, the growth of bushes and fruit bearing berries will deteriorate significantly. In view of this, autumn dressing of raspberries is a mandatory event for every gardener.

This article will discuss what kind of fertilizer is needed and which cannot be applied to the soil when growing raspberries in the fall. You will also learn what kind of care this plant needs before the onset of winter cold.

Nitrogen. Do I need to make it into the ground in the fall

Before the raspberry is fed in the fall, weed plants are removed from the row spacing. Then it is necessary to dig the ground between the rows to a depth of about 15 cm, and in the rows between raspberry bushes - 8 cm deep.

Once in 3 years before digging in the aisle make manure at the rate of 4 kg per 1 m2. Nitrogen fertilizers stimulate the growth of shoots, which prevents their maturation. As a consequence, reduced winter hardiness raspberry. Some gardeners, on the basis of this, come to the wrong conclusion, which is that at the end of summer it is impossible to add nitrogen to the soil.

However, starting in August, perennial plants, including raspberries, begin secondary root growth. During such a period it is very important that there is enough nitrogen in the soil. It is usually not necessary to feed bushes specifically with this trace element, as there is still a sufficient amount of soil in the soil, provided that it was fertilized in summer. In addition, during this period the plants redistribute the nitrogen produced in summer, which was deposited in the leaves and shoots.

What fertilizers are best suited for autumn feeding

Gardeners and gardeners prefer to apply organic matter as a fertilizer for raspberries. Among the organic feeding:

  • Compost.
  • Ash.
  • Manure.
  • Siderata.
  • Bird droppings.
  • Peat.

Consider each of these fertilizers separately.

Compost. Its features and benefits

If you properly prepare the compost, then its efficiency may be higher than with manure fertilizer. Sufficiently rotted compost saturates the soil with nutrients. In addition, it kills pathogens that may well settle in the ground during the growing season of raspberries.

To prepare high-quality compost, you need to throw into the pit:

  1. Sawdust.
  2. Kitchen waste (vegetables, tea leaves, fruits, coffee grounds and cereals).
  3. Hay and straw.
  4. Cut grass.
  5. Thin stems and branches of garden trees and bushes.
  6. Seaweed.
  7. Recycled wood, previously passed through a garden shredder.
  8. Ground weeds.
  9. Rotted leaves and other garden waste.
  10. Dead manure
  11. Natural materials such as paper and fabric.
  12. Cut grass.
A warning! It is important that weed seeds do not fall into the compost pit.

Manure - natural organic fertilizer

To feed raspberries should use rotted manure. It will not only serve the bushes as a fertilizer, but also protect the roots of the bushes from the cold, as it has good thermal insulation properties. How to use manure to fertilize raspberries in the fall, has already been mentioned in the article above.

Manure is very useful for raspberries as it contributes to the rapid growth of bushes in early spring. It saturates the soil with all the microelements necessary for raspberries.

Ash as fertilizer for raspberries

After harvesting under the raspberry bushes can scatter the ashes. This fertilizer is rich in potassium, which, when accumulated in tissues, yields a harvest of sweet berries. In addition, in the ashes there is lime, which acts as a neutralizer of acidity in the soil, which raspberries do not like very much. Best for raspberry leaf fertilizer from burnt grass, wood and straw.

Important! Ash obtained by burning small branches and twigs, has in its composition more nutrients than the one obtained by burning old stumps and trunks.

Bird droppings

This organic fertilizer is the most concentrated. In view of this, it can only be used in diluted form. The most suitable for fertilizing raspberries is chicken droppings. Bred it in a ratio of 1:20. It is important to distribute the fertilizer evenly.

A warning! If you make a stronger concentrate than 1:20, then the roots of plants can get serious burns, because of which they will not only get sick, but even die. Therefore, use bird droppings should be very careful.

Peat, as a dressing for raspberries

In peat there are not so many useful substances as in other types of organic fertilizers, however, its introduction into the soil of raspberry does very well affect the bushes. The fact is that it is peat that improves the soil structure. It is often used as mulch.

The soil into which the peat has been introduced becomes looser, thanks to which the roots are provided with good oxygen exchange. Peat is often used as part of peat compost.

Use of siderats

Siderats are planted between the rows of plants, which in the autumn serve as an excellent feeding for raspberries. They are sown in late July or early August. Clover, mustard and vetch can serve as siderats. After harvesting, the aisles are mowed and dug along with the ground. So, the green mass in the spring rot, enriching the soil with all the necessary microelements for the full development of raspberry bushes.

Mineral fertilizers

If you are unable to apply organic matter to the soil, you can replace it with mineral fertilizers containing potassium, phosphorus and nitrogen. If we talk about nitrogen-containing fertilizers, they are made in the spring and early summer. In this case, you will need ammonium nitrate per 1 m2 - 13 g of fertilizer. You can also fertilize raspberry urea in the proportion of 9 g per 1 m2.

In autumn, the soil raspberry needs potash fertilizers. At the same time in their composition should not contain chlorine. Potassium sulphate can be used as a feed at the rate of 25 g of fertilizer per 1 m.2. Potash fertilizer application increases raspberry frost resistance.

In addition to the above mentioned fertilizers, monophosphate and monopotassium phosphate can be applied to the soil. These drugs are soluble and absorbed by raspberry completely, without residue. However, the fertilizer should be buried in the soil, closer to the roots of the plants. At the bush will need 40 g of funds. Calimagnese is another potassium-containing drug. It also contains magnesium. The tool is not very concentrated, so its dose can be increased by 2 times.

Mulching as a means of protection from frost

To make the fertilizer brought maximum benefit to the bushes, the roots must be covered before hibernation. This is due to the fact that the land cleared of weeds dries out faster and does not protect the root system from freezing.

Important! The amount of moisture affects the formation of flower buds and the winter hardiness of the raspberry.

As a covering material, sawdust, peat and mowed grass are often used. If you live in a harsh climate, the bushes can also be bent down and covered with non-woven material to protect them from the fierce cold. This is especially important if there is little rainfall in your area in winter. Of course, covering material should be fixed, for example, with stones.

Fertilizing and preparing raspberries for wintering is an important stage in the cultivation of this useful and very tasty berry. Such activities do not require any special skills, so even an inexperienced gardener can handle them. Having spent several hours in the fall on raspberry care, you will get a bountiful harvest next season.
