Product specification of young blackberry plants
Overwintered green plants are the quickest way to produce a full crop. These are micro-propagated, virus-free plants thinned out in the greenhouse, hardened off in the open air and overwintered in the chiller. There are 60 plants in each plant culture tray. The best time to plant is in April. In optimum conditions, the plants can put out 3 - 5 roots, even in their first year, and can reach a height of up to two metres. They achieve close to their full yield even in the year after they are planted.
Virus-free green plants propagated in the year of planting. The plants are cultivated in 60-plant cultivation trays and hardened step by step before delivery . They are approx. 10 -15cm high. Planting should take place from the end of August to the end of September. After that, there is a risk of winter damage. Later planting is also possible in sheltered locations.
In blackberries, the harvest period can be restricted in a similar way to strawberries by the use of "Long Canes".Long Canes are cultivated in 3.5 -4.5l pots in the preceding year. Two roots are usually cultivated per pot, at a height of 1.60 to 1.80 m. In winter, these plants are stored and cooled to -1.5 °C. In the following year, they can be taken out of the cold store at the required time and then planted. Fruit will start to be harvested from 70 to 90 days after planting, depending on the date of planting.
Other varieties can be supplied if they are pre-ordered in good time.
Description of varieties
Growth site requirements
Blackberries do not require any particular type of soil, but they do prefer medium-heavy soil that drains well and is slightly acidic. They do not tolerate compact and soggy soils. They thrive in sunny spots sheltered from the wind. How susceptible they are to frost depends on the variety and growth site. When planted in a favourable site (sunny, sheltered from the wind), blackberries can be cultivated at up to 800 m above sea level. In very low temperatures and areas prone to late frost, winter protection for the plants is recommended.
The plants must be placed deep enough in the ground so that the upper rim of the root ball is covered with 2 cm of earth.
Before planting, make sure the root balls have been thoroughly soaked. Once planted, make sure the area around the roots remains sufficiently moist, particularly during the initial growth phase.
The use of plastic film increases the risk of vole infestation. Take preventive action in good time!
