Can bark mulch be used in vegetable gardens

Bark mulch often evokes images of ornamental borders, yet it can play a valuable role in a vegetable garden when applied judiciously. The chips form a porous quilt that suppresses weeds, slows evaporation, and softens the impact of heavy rain. Their slow decomposition adds organic matter without sudden nutrient surges.

Timing matters. Wait until the soil has warmed in late spring, then spread a layer about five centimetres deep between rows, keeping stems clear. This barrier holds moisture during summer droughts and keeps mud from splashing onto lettuces and tomatoes, reducing the spread of soil-borne diseases.

Because bark is carbon-rich, microbes may draw nitrogen from the soil surface as they break it down. Counter this by incorporating well-rotted compost or a light organic feed before mulching. Shallow-rooted crops like carrots appreciate the steady moisture, whereas hungry courgettes will enjoy the extra feed.

Choose small to medium chips rather than large nuggets; they knit together yet remain easy to fork aside at planting time. Screened pine or mixed conifer bark from AHS LTD fits the bill, free of contaminants and evenly graded. With thoughtful application, bark mulch can protect vegetables, boost soil health, and reduce upkeep throughout the growing season successfully.
