How to prevent weed growth through gaps in concrete outdoor tree boxes?
Weeds growing through gaps in concrete outdoor tree boxes can be unsightly and difficult to manage. Fortunately, there are several effective methods to prevent this issue. First, ensure the gaps are properly sealed using a high-quality concrete caulk or expandable foam. This creates a barrier that blocks weed seeds from taking root. Another approach is to install landscape fabric beneath the tree box before filling it with soil, which inhibits weed growth while allowing water drainage. Regularly applying a natural weed suppressant like corn gluten meal can also help. For long-term prevention, consider using a thick layer of mulch or gravel to cover the soil surface, reducing sunlight exposure and discouraging weed germination. Combining these strategies will keep your tree boxes weed-free and low-maintenance.
