Compatibility Analysis

The short answer is: yes, you can plant cabbage, sweet potatoes, and oregano together, but with some considerations. These plants have different growth requirements and characteristics, which can be complementary if managed properly.

Cabbage is a cool-season crop that thrives in full sun with well-drained, fertile soil. Sweet potatoes, on the other hand, prefer warmer temperatures and are more tolerant of varying soil conditions.
