You can grow different berries such as blackberries, raspberries, blueberries, josta berries, currants red or white, but also grapes and kiwis are berries. I like them all, in yogurt or to make juice or syrup, but this year I'm going to fill the Rumtopf with them. The recipe for this will follow as soon as the rumtopf is full and I can tell you how delicious it turned out!
The currant bushes essentially require little care. In a dry spring you have to give enough water, but that goes without saying.
Every year I give them a handful of lava flour and some Mycorrizha powder, these are fungi that live with the plants roots and help them absorb nutrients.
A grape and a kiwi both have approximately the same pruning method. This is pruning back in May to the sixth leaf and pruning all side branches back to the third leaf. So all the power can go to developing good fruits. Never prune in winter!
A currant, on the other hand, is always pruned in winter when all the leaves have been removed and it is not freezing. Cut away all low-growing branches and thin out the wood so that light returns to the heart of the plant. Don't be afraid to prune because the better you prune the more fruit you will have next year. Take a look at the following video by Frank Anrijs, the author of the book Permaculture principles in the natural vegetable garden. (A few more books available to order)
The blueberry is an exception, but all berries grow on all soils, but loam is the favourite. heavy clay soil can be worked with lava grit, this ensures that the soil becomes looser and you immediately add minerals, making your berries even healthier.
As mentioned, blueberries are an exception to this, they only want to grow well in an acidic soil such as hydrangea soil.
finally one more look at my budding peaches, this will be her first year fruiting outside there are 5 of these pretty boys hanging in there. These will taste good in the rumtopf Hhmm!
