Start with high-quality, well-draining soil that provides nutrients to your plants. Use potting mix or a soil blend designed for containers to ensure that the soil stays loose and airy.
Planter boxes should have drainage holes to prevent water from accumulating at the bottom, which can lead to root rot. If your box doesn’t have built-in drainage, consider adding a layer of gravel.
Planter boxes are more exposed to environmental factors than in-ground plants. In hot weather, consider placing your planter box in a shaded area to prevent the soil from drying out too quickly.
To prevent mold, algae, or pest infestations, clean the planter box between planting seasons. Empty the box, scrub it with a mild soap solution, and rinse thoroughly to remove any residue or build-up.
For wooden planter boxes, inspect them regularly for signs of rot or weather damage, especially if they are exposed to the elements. Applying a sealant can prolong the life of the box.
