Blackcurrants prefer a rich, well-drained soil that is slightly acidic. It is important that the soil is well aerated to promote healthy root development.
The ideal pH for blackcurrants is between 6 and 6.5. If the soil is too alkaline, adding peat or compost can help acidify it.
Before planting, amend the soil with compost or well-decomposed manure to improve soil structure and provide necessary nutrients.
Planting
Plant blackcurrants in early spring or autumn in a sunny or partially shaded spot. Make sure to space the plants about 1 to 1.5 meters apart.
When planting, bury the roots up to the crown of the plant and water thoroughly to encourage rooting.
Ensure good air circulation by spacing blackcurrant plants 1 to 1.5 meters apart in rows.
Watering
Blackcurrants need regular watering, especially during the growing season. Water the plants to keep the soil moist but not waterlogged.
Avoid over-watering in winter to prevent excess moisture that could lead to root rot.
Apply mulch around the roots to help retain moisture and protect the roots during dry spells.
Pruning
Pruning blackcurrants is important for optimal fruit production. Remove dead branches and old growth in early spring.
For strong growth and high-quality fruit, prune branches above a bud using a sharp pair of pruning shears.
Fertilizer
Feed blackcurrant plants with a balanced fertilizer in early spring to promote healthy growth.
Supplement with a potassium-rich fertilizer at the beginning of the fruiting season for better fruit production.
Harvesting
Blackcurrants are ready for harvest when they are fully ripe and have a deep black color. Do not let them over-ripen as they may fall off.
To harvest, gently pull the clusters and pick them in stages. You can store the berries in a cool place for a few days or freeze them for later use.
