A well-draining, all-purpose potting mix will do for container-grown borage.

To prevent the disease, confirm the plant has sufficient air circulation and that they are properly watered.

Borage will mature about eight weeks after planting.

Borage is an annual, completing its life cycle in one growing season.

It does, however, self-seed very readily, so it may appear to be perennial.

Borage plants don’t suffer from a lot of issues.

They may respond poorly to underwatering, overwatering, or temperature fluctuations.
