Deadlines
Jumbo blackberries can be rooted in the ground during 2 seasons. In spring, bushes are planted when the heated layer of soil reaches 40 centimeters. If the autumn period is chosen for planting, then all work is advised to be completed half a month before the onset of the first frost.

Selected seedlings are kept in biogrowth stimulants before being placed in the ground. Many gardeners use Kornevin for these purposes. This method of preparation will help the plant more easily survive entering new conditions.
Planting scheme
The compact size of Jumbo blackberries allows plants to be planted more densely than other varieties. Shrubs are placed a meter apart from each other, and sometimes the distance is reduced to 70 centimeters. About 2 meters are left between the rows.
Drainage made of crushed brick or gravel is placed at the bottom of the hole. And then the fertile layer is covered. Ash, manure and phosphate fertilizers are added to garden soil. It is important to ensure regular watering and not allow the soil to dry out.
