When planting seedlings or cuttings, leave approximately one meter distance between each plant. Bury them to a depth of between 5 and 10 cm, according to the size of the cutting.

Blueberry plants grow best when they have plenty of room to spread their runners.

4. Water frequently

Make sure that the soil is always moist, but without producing puddles.

5. Fertilize the soil

Fertilize frequently to stimulate stolon growth.

For the first year after planting, fertilize your blueberry bed with a fertilizer containinghigh nitrogen content.

Fertilize the soil three times: at the start of growth, during flowering, and when berries start to form.

After the first year, it will be necessary to reduce the nitrogen supply so that they stop expanding and take root and form upright plants.

Every two years, starting from the second year of age, it is recommended to cover the soil with a thin layer of sand, about 1 cm. This will help root the runners and prevent weeds.

6. Prune runners

Beginning in the third year of growth, blueberry plants will need to be pruned in the spring to control runners and encourage the development of upright plants.
