Should You Mulch Your Garden?

By David AllenApril 7, 2026

Mulching your garden is a common practice among gardeners, but the question remains: should you put mulch on top of your garden? The short answer is yes, but with some considerations. Let's delve into the benefits, types, and application methods of mulch to help you make an informed decision.

Mulch serves multiple purposes in your garden. It helps retain soil moisture, suppresses weeds, regulates soil temperature, and improves soil health over time. But not all gardens benefit equally from mulching. For instance, some plants prefer bare soil or require specific mulching techniques. So, it's essential to understand your garden's needs before applying mulch.
