1. Plant mint at the right time

Plant mint after last spring frost date. The ideal soil temperature for planting mint is 55°F-70°F. Mint often dies back in cold-winter climates, but underground roots survive and the mint comes back in the spring.

In the low desert of Arizona, plant mint transplants from February to April and again from October to November.

Keep mint contained by growing in its own container or in a bed with different varieties of mint grown together.
