Weeds Invading Containers and Planters
When potted herbs or ornamental planters show weeds poking through drainage holes, it means your soil mix is already contaminated. Those weeds compete with container plants, which have limited soil volume to share.
I refresh my container media annually and hand-pick any stray seedlings at the first sign. Knowing my basil or petunias aren’t battling crabgrass roots makes me beam with pride at my pot displays!
