Can I grow blackberries in an EarthBox?Updated a year ago

Yes, you can grow blackberries in an EarthBox. We recommend growing them in the EarthBox Original. If you choose a thornless trailing type of blackberry plant, it will need to be trellised, which our 7’ Staking System can take care of. If you opt for an erect variety, it may not require any added support.

Blackberry plants do best with a balanced fertilizer, such as our 7-7-7 Plant Food. Avoid fertilizers that have an increased nitrogen (N) percentage to prevent overgrowth of foliage. Since blackberries prefer a neutral or mildly acidic growing environment, always add dolomite to help reduce the natural acidity of the peat-based growing medium. 

Some thornless trailing varieties that do well include “Chester,” “Natchez,” and “Triple Crown.” Also, the thornless erect varieties of berry that do not require trellising and staking are ideal for container-grown blackberries. Amongst those are: “Arapaho,” “Kiowa,” and “Ouachita.”
