Even if you are a beginner in gardening, then you, of course, still know about the great importance in agriculture of fertilizing and fertilizing. They enrich the soil with nutrients that are vital for good growth and development of plants.
If we talk about raspberries , then for her feeding is a pledge of abundant fruiting. Fertilize raspberry mainly in autumn, after the last harvest in this season is removed. Autumnal feeding, firstly, will allow to properly prepare the plant for winter, and secondly, give raspberry a push to increase yields for the next season. Therefore, if you are still not sure whether to feed raspberries in the fall, be aware - this is more than advisable.
So, let's find out what fertilizers can feed the raspberries in the fall.
How to feed raspberries after pruning?
Autumnal fertilizing is usually carried out after the raspberry is cut off, and the soil under it is dug up. They include the application of the following fertilizers:
- Bird (in particular - chicken) litter is considered one of the best types of fertilizers for raspberries. Litter in liquid form should be distributed throughout the soil of raspberries in autumn, after pruning shoots.
- The manure is brought in before digging in order to mix it with the soil. In this case, the substance besides the nutrient base will also become a good winter shelter for the roots of the plant. Experienced gardeners recommend to introduce manure in an amount not less than 4-6 kg per square meter, but it should be done no more often than every 3 years. Manure is usually alternated in years with other types of fertilizing.
- One of the options for feeding raspberries in autumn, if there is no manure, is compost . In order to get a good fertilizer by autumn, it is necessary to accumulate plant waste (foliage, corn cobs, weeds, weeds, tops, etc.) in special compost boxes throughout the summer. Lashing, organic becomes a good fertilizer.
- Sometimes in the raspberry plant the siderates - mustard, blue lupine, vicoes. Planted them in June, and under winter, they are embedded in the soil. Rotting there, by spring the greens of the siderates will enrich the soil in the raspberry with nutrients.
- Increase the productivity will help and the introduction of peat , which improves the structure of the soil in raspberry. However, do not overdo it with peat: it is better to combine it with other types of fertilizers.
- Mineral fertilizers (potassium salt or superphosphates) should be applied in a ratio of 40 or 60 g per raspberry bush. To do this, make grooves in the aisles at a distance of at least 30 cm from the bushes.
As for nitrogen fertilizers, they should not be used in autumn. They provoke a rapid growth of the plant, which after trimming should enter into a period of rest, and this, in turn, can lead to negative consequences, such as raspberry frost in the winter.
Planning, rather than feed raspberries in autumn after pruning, pay attention to the appearance of plants. He will tell you what kind of nutrients currently lacking soil in your raspberries:
- a lack of iron will tell the yellowish color of the leaves with green veins;
- deficiency of magnesium leads to poor growth and yellowing of the leaves from the center to the edge;
- if there is little phosphorus, the raspberry shoots will be weak and thin;
- with a lack of potassium, the foliage will be brown and as if burned around the edges, and the plant itself does not tolerate winter well;
- if the leaves of raspberry are small, yellowish tinge - perhaps, it lacks nitrogen. But with its overabundance, shoots and leaves, on the contrary, go into growth, but immature berries crumble, and the level of fruiting is reduced.
