- locations that receive morning sun and afternoon shade
- Blackcurrants do not grow well with other plants
- Blackcurrant can be planted twice a year, in autumn and with sufficient watering, can be also in early spring. The plants are slightly deeper than they grew in their nursery pots.
- Blackcurrant planting machine DARIA: is designed for easy and fast planting of blackcurrant seedlings. (Watch Video)
- Space between plants: 50 cm to 70 cm
- Space between rows: 3.3 m to 4 m
- Space at the end of the row to the fence: 6 m

Why and when to prune blackcurrant bushes?
The goal of pruning is to grow the side shoots, which will bear fruit the next year. There must always be enough young main shoots because after about a few years shoots only form isolated side shoots with a few small fruits. In addition, it is an important step in preparations for a fast and efficient harvest of berry bushes with mechanical harvesters to give the bush its bushy shape as the fruit-bearing side shoots are formed.
Cut out a quarter of the branches each year, aiming to remove old non-productive, weak growth, and low-lying branches. With the berry pruning machine FORMER is able to cut the lower branches to stimulate strong growth from or near the base, remove weak shoots, and any dead wood.
Blackcurrant pruning can be done after harvest time during autumn and early spring. Prune sprawling branches laden with fruit for easy picking. (Watch Video for blackcurrant min 01:07)
Weed Control in Organic Blackcurrant Plantations:
For Organic Blackcurrant Shrubs:
We offer a full line of mechanical and hydraulic hoeing machines to control-weed in blackcurrant plantations for both young and mature bushes. The weeders are designed mainly for berry plantations, and they have been upgraded continuously to achieve the highest and efficient performance.
Weed Control in Conventional Blackcurrant Plantations:
For Non-Organic Blackcurrant Shrubs: The herbicide strip sprayer for blackcurrant bushes TEKLA is designed to reach the weeds growing under blackcurrant. A special design of the sprayer modules enables spraying as close to a bush as possible and the use of protective curtains and ejector nozzles protects against spraying branches and shrubs
When to Harvest Blackcurrants?
Harvesting Blackcurrants starts early summer onwards, it’s related to weather conditions, and depending on the variety. The way to know they are ready to harvest when they are dark and shiny. Try to harvest blackcurrants during dry time and avoid harvesting during wet time as they may go mouldy.
How To Harvest Blackcurrants?
The mechanical harvest in blackcurrant plantations can reduce costs by 80% and improve labor productivity.
For harvesting blackcurrants, we offer a full line of blackcurrant harvesters. One of the best-known blackcurrant harvesters in Europe is the half-row berry harvester JAREK 5. Our Blackcurrant harvesters have been operating for several decades, we have sold more than 1500 harvesters under the name of JAREK for different types of berries. It’s highly recommended for plantation from 1 ha to 15 ha.
Above 15 ha, we recommend the berry harvester OSKAR A01 a pull-type for collecting currants from the whole row. For plantations above 30 ha, we recommend the self-propelled blackcurrant harvester OSKAR 4WD.
- We guarantee a harvest accuracy from 95% to 99% and the amount of impurities does not exceed 1% as the best result achieved so far in the market due to the feature of the modular design.
- Picking currants from both high and low shrubs.
- No damage of shrubs due to design technology that has been used in the harvester.
- Fruits for fresh market.
