Blackberry is a relatively nutritious fruit that is grown in most parts of the country.
There are many varieties of blackberries, and we need to choose the ones that are resistant to diseases and easy to cultivate. So how to care for blackberry bushes?
It is possible to increase the yield and at the same time reduce the cost of cultivation. So if you want to achieve high yields of blackberries, how do we do it? This article is with you to find out.
IMPROVING THE SOIL
We have to improve the soil, which consists of the following three main measures.
DEEP TILLING TO IMPROVE THE SOIL
The root system of blackberry is sensitive, so the soil layer should be well aerated to facilitate survival.
If the soil has a high organic matter content, it is conducive to nutrient absorption. Depending on the soil, we have to take different measures to improve the soil properties when the blackberry is not yet in the garden.
If it is in barren mountainous and hilly areas, then we have to open the soil and apply sufficient organic fertilizer, such as crop straw, leaves, dead grass, etc., in the ditch.
These organic fertilizers should be mixed with the soil, and then transplant the blackberry seedlings after a period of deep tillage and idleness, so that the survival rate is higher.
MID-TILLAGE AND WEEDING
After the site of the orchard is determined, we have to weed it regularly in the first and second years.
The main purpose of weeding is to increase the permeability of the soil and to remove insects, the number of weeding is 6 to 8 times.
After three years, when the blackberry orchard is basically established, then we can reduce the number of weeding.
But to turn the soil in a timely manner, the purpose of this is to make the soil temperature up and eliminate weeds.
USE THE TECHNIQUE OF MULCHING
The blackberry planting process does not tolerate high temperatures, so we better in the spring when the climate warms up, the temperature is too high to hurt the seedlings.
So we have to put straw and stalks on top of the soil, which can increase the humidity of the soil and prevent the moisture from evaporating too fast.
FERTILIZATION OF BLACKBERRIES
Fertilization of blackberries is based on crop fertilizers and other fertilizers containing chemical elements.
This is because chemical fertilizers have to be converted in order to be absorbed by the plant, while there are organic fertilizers inside the crop that can be absorbed directly. But chemical fertilizers can single-handedly supplement the nutrients that the plant lacks, and are also more than indispensable.
With the joint action of both, this way we can maintain and increase soil fertility, improve soil structure, and increase soil permeability.
We should avoid putting harmful substances in the fertilizer, which will not only not protect the plant and increase the nutrients but also may cause soil pollution.
- Apply basic fertilizer in autumn and winter.
In general, we choose to apply basic fertilizer in winter. To use high-temperature fermentation or organic fertilizer after decomposition.
In addition to this, a small amount of chemical fertilizer is also required. The main method of fertilization is to use the method of digging ditches or the method of fertilizing the whole garden.
- Fertilization during the growth of blackberry.
During the growth period, we need to fertilize depending on the growth of the seedlings. If the plants in the orchard are growing more vigorously, then we mainly fertilize.
Fertilizers with phosphorus and potassium are the main types of fertilizers. But if the growth is poor, we will mainly use fertilizers with nitrogen.
This is because nitrogen fertilizers help the plant to absorb nutrients and promote the growth of branches and leaves.
WATER CHANGES AND DRAINAGE OF THE ORCHARD
In general, before the plants sprout and during the period when the shoots are growing, the seedlings are growing vigorously and need a lot of water.
Then it is necessary to water more during this period, from March to April. During the period from flowering to fruit expansion, watering should be mixed with fertilizer to increase the fruit area and improve the taste of the fruit.
During the fruit ripening period, because of the high temperature, we need to increase the frequency of watering the orchard to maintain the water content in the soil.
If we talk about low-lying areas, the accumulation of water damage can occur due to excessive rain in spring.
Because the fragile root system of blackberry is very intolerant to waterlogging, the amount of rain, the soil inside the low oxygen content, poor respiration will lead to blackberry root rot, so we must do a good job of drainage in a timely manner.
