Overgrown Mint Garden Management and Maintenance

Mint gardens can quickly become overgrown, but with the right management and maintenance, you can keep them under control.

Regular pruning is essential to prevent mint from spreading too far. Prune your mint plants every 1-2 weeks during the growing season to maintain their shape and prevent them from flowering.

Cutting back the stems to about 1 inch from the soil surface will encourage new growth and prevent the plant from becoming leggy. This will also help to promote a bushy shape and prevent the mint from taking over your entire garden.

Overwatering is a common mistake that can lead to mint becoming overgrown, so make sure to water your mint plants sparingly. Mint prefers moist soil, but it's better to err on the side of caution and underwater than to overwater and risk root rot.
