The main pros and cons of Black Diamond blackberries
Growing a plant
In order for a crop to develop normally and bear fruit well, it needs to be properly cared for.
Deadlines
It is permissible to plant the crop in spring and autumn. It is best to carry out planting work in early March. In the fall, this should be done before the first cold weather. In this case, it is recommended to shorten the cuttings to 25 centimeters.
Selecting a location
Blackberries require a well-lit place to plant. When grown in the shade, the plant will not produce a good harvest. It is not recommended to plant blackberries near raspberries. Such placement of crops increases the risk of developing pathologies. In addition, it is advisable to change the site every 7 years.
Before planting, it is recommended to clear the bed of weeds and dig it up. Then you should make holes 50 centimeters deep. The gap between the bushes should be 100-120 centimeters. In each hole you need to add 50 grams of potassium sulfate, 5-6 kilograms of humus, 100 grams of superphosphate.
Preparation of planting material
For planting, it is worth using seedlings with closed roots. In this case, the roots must be moistened. It is recommended to buy seedlings from a nursery or from trusted gardeners. Bushes should include 2 stems and 1 live bud.
Planting scheme
Plants must be planted in rows, the distance between which should be 2 meters. There is no need to reduce this distance. As the blackberry grows, it will require free space.
Fences, walls or other vertical structures should be located at least 1 meter away from bushes.
Subtleties of crop care
In order for the plant to develop normally, it requires proper care. It is important to follow a number of recommendations.
Watering
For watering, you should use a drip system or irrigate the soil 2-3 times a week. To avoid waterlogging of the soil, it must be systematically loosened.
Fertilizers
In the first year of bush development, it is necessary to use fertilizers and mulch the soil. To increase yield parameters, it is recommended to use organic products and compost fertilizers. Apply 5 kilograms of fertilizer per 1 square meter. At the initial stage of crop ripening, it is worth using potassium compounds.
Wintering
The variety is resistant to frost and can withstand temperatures of -27-29 degrees. However, in winter it is better to cover blackberries. This can be done with humus, straw, spruce branches, and sawdust. It is also acceptable to use cardboard, film, and hay.

- Raspberry and spider mites. For prevention, you should use Karbofos. Actellik and Fufanon help fight parasites.
- Stem raspberry gall midge. In this case, the stems become covered with swellings. “Karate” and “Calypso” will help eliminate parasites.
- Stem fly. Parasites feed on young shoots of bushes. To combat them, Actellik and Karbofos are used.
The most common diseases of blackberry bushes include:
- Gray rot. The pathology affects flowers and fruits. “Switch” and “Teldor” will help you cope with it.
