The most popular methods for blueberries are propagation using sinkers and cuttings. You will soon have turned a blueberry bush into many blueberry bushes and you can enjoy a rich harvest. We introduce you to how you proceed with the propagation and what else you have to consider.

Propagate blueberries by lowering

The propagation via subsidence can take place during the growing season. For this purpose, longer, young shoots are pressed down near the ground and covered with soil. The tip of the shoot should protrude from the ground. So that the shoot does not bend back up, you should also anchor it with a hook or simply weigh it down with a stone. When the blueberry’s sinker has developed enough roots after a few months, you can separate it from the mother plant and transplant it.

Propagate blueberries with cuttings

Propagation by leafy shoots is a very simple and popular method for blueberries. In August, cut vigorous annual shoots into pieces about 10 cm long and remove the lower leaves so that only the top two or three leaves remain. Then the cuttings are placed deep in a pot with a loose, acidic substrate and poured abundantly. It is best to place the pots in a bright, warm place. In the first few weeks after plugging, the pots can be covered with cling film to prevent the substrate from drying out.

As soon as the plucking test (pulling gently on the cutting) shows that there are new roots, you can remove the foil. When the cuttings have formed enough roots, they can be transferred to a larger planter, in which they are usually wintered cold (down to -5 ° C). In spring, the plants then begin to sprout and can be planted outdoors from June.

Propagate blueberries by sowing

In principle, it would be possible to propagate blueberries via seeds. However, it is of little importance in gardening practice. Cultivated blueberries ( Vaccinium corymbosum ) were bred to develop as few kernels as possible. The fruits of wild blueberry bushes ( Vaccinium myrtillus ) are more likely to be found.
