Since the blackcurrant bushes can be kept relatively small or cultivated as a high strain, the blackcurrant is also suitable for a bucket planting on the balcony or terrace, if there is no garden. For the implementation of a sufficiently large bucket is needed because the berry is a Flachwurzler, it needs plenty of space on all sides. Since waterlogging in the pot is the main reason, drainage above the drain hole made of potsherds or gravel must be created. Ideally, plant fleece is added to this so that soil can not clog the drainage. Then a part of the prepared soil is filled. Garden soil should be mixed with compost, sand and loam, alternatively, if not available, normal potting soil for mixed crops from the trade. Then proceed as follows:
- remove small plant from the pot
- Water rootballs well and use
- fill up remaining soil
- Press lightly and pour
- put in a sunny place
- In winter, the bucket must be protected from frost
- cover with plant fleece or rice mats
- Give mulch to the earth
- Put the pot on styrofoam or a thick wooden board
Tip: Although the blackcurrant does not necessarily have to be repotted, it should still be offered about every two to three years of fresh soil.
Substrate & soilCurrants, including blacks, like it equally moist. However, waterlogging should be avoided here, because the soil at the site should not be too wet either. Otherwise, the shrub needs the following substrate to make as many delicious berries as possible:
- a mixture of garden soil, compost sand and clay is ideal
- Mulch scattered all around preserves moisture
FertilizeThe blackcurrants are usually fertilized twice a year, once in the spring before budding, the second time in autumn after harvest. Ideal is the use of compost, as it is a natural fertilizer that is always better for plants whose fruits are consumed. Mineral fertilizer can easily falsify the taste, even this is not quite as healthy for the human body in a larger intake of the fruit. Therefore, it is quite sufficient if the shrubs are fertilized with compost. On more fertilizer inputs over the summer can also be dispensed with.
- it is dry and hot, pour every day
- ideal in the early morning or late evening hours
- just pour on the roots, not on the bushes
- in spring and autumn the rain is enough
- Pour potted plants in the rain, too
- Natural rainwater often does not reach the pot
multiplyThe blackcurrant, as well as its red and white sisters, can be propagated by cuttings. Therefore, if there is a very tasty variety in the garden, then it can easily be pulled further shrubs, the yield is even greater. In the propagation by cuttings is ideally proceeded as follows:
- The ideal time is the late autumn
- Choose the shrub with the highest and tastiest yield
- cut off healthy, one-year-old shoots
- Use a sharp knife for this
- cut the shoots into equal pieces
- about 20 to 30 cm long
- Cut the lower side diagonally
- can be put into a breeding bed with loose soil
- insert each cuttings at a distance of 10 cm
- Insert about 15 cm deep
Tip: If you do not have a nursery bed, you can also put the cuttings in individual small pots filled with seedling soil.
overwinterThe blackcurrant is absolutely hardy and requires cultivating in the field, no winter protection.
To cutThe blackcurrant must be cut regularly every year in autumn after harvest, with the first cut already being made directly after planting in the fall. But the black fruit definitely needs a different cut than is usual with the red and white varieties. Because Ribes nigrum bears the fruit on the one-year, long shoots that grow on the side. But this way the shrubs can be kept in shape very well by a wrap around:
- remove all weak shoots at the base and main branches
- remove the oldest shoots directly from the base
- leave new shoots from the base
- In spring, the main branches are cut
- for this purpose over the second or third side shoots caps
Cut high stemSome gardeners prefer the blackcurrant as a high strain. These can already be purchased in a well-stocked trade. Berries cultivated in a bucket are often planted as a high stem, as they do not need as much space as a shrub. Unfortunately, this is often at the expense of the profitable harvest. Nevertheless, a tree trunk is also an eye-catcher in the field and should be cut as follows:
- remove all weak shoots
- all shoots that do not grow outward in the crown
- Shorten the crown around
- Remove oldest main drives in the middle
- leave new shoots
- several shrubs together close together
- Always keep the soil evenly moist
- Several different varieties next to each other influence the pollination
- even if self-fertile, more flowers are pollinated
- Night frosts are expected to cover overnight with plant fleece
DiseasesThe blackcurrant is prone to red pustule disease. This causes infected branches to die off, showing orange-red spots on the dead wood. If the berry bush is affected by this disease, only a strong pruning helps to the base. The leaf fall disease is very common in Ribes nigrum. This is a fungus that causes the leaves to drop prematurely. Against this fungicides can be used. Especially in very humid summers, these diseases can be seen.
Tip: And the location should also be inspected in such a case. If the shrubs are close to conifers, this may also be the cause, because these are carriers and hosts of various fungal diseases and thus also favor a black currant infestation.
pestsIn the case of the pests, especially spider mites, scale insects, gall mites and aphids should be mentioned. If one or the other infestation becomes visible, insecticides can be used. If you do not want a chemical club, you can try to use a dishwashing liquid-water-vinegar mixture or a self-prepared nettle colander against the annoying pests.
The blackcurrant with its many tasty varieties is a robust berry fruit that should not be missing in any garden. Because not only the fresh fruits are delicious to enjoy, they can also be processed quickly and easily to many treats. If you want to enjoy the delicious berries throughout the year, from early summer to autumn, plant different varieties. Because there are early, mid-early and late shrubs. If these are all grown together in a garden, a longer harvest can be expected. Otherwise, the care of the robust blackcurrant is not much to pay attention to, because it is quite undemanding and needs in the winter in the field also no protection.Only for the cut in the fall a little time should be spent, so that next year again a rich harvest is guaranteed.
