Self-fertility and the need for pollinators

Landing
Autumn planting for this variety is best suited. Such a moment is especially important for regions where it is warm for a long time in autumn.The spring planting must be completed before the juices begin to move and the buds swell. Openwork currant does not like lowlands. It is important to make sure that the soil is fertile, has a neutral or slightly acidic reaction.

Water the currants systematically and with plenty of water. Having irrigated it, the soil is loosened. You can loosen the soil even through mulch. When spring comes, the bushes are fed with complex fertilizers based on nitrogen. If a large number of ovaries are formed, and the branches begin to bend under the weight of the berries, you will have to put up supports.
