The answer to 'stone walkway not growing' is that there can be several common causes, including poor soil preparation, lack of sunlight, and improper drainage. Symptoms may include moss growth, uneven settling, and sparse or patchy vegetation. Solutions can range from simple maintenance to more extensive repairs, depending on the underlying issue.
If the walkway was not properly prepared before installation, with a solid base and well-draining soil, the stones may sink or shift over time, creating an uneven surface that inhibits plant growth. Similarly, if the area doesn't receive enough sunlight, certain plants may struggle to thrive. Improper drainage can also lead to pooling water that drowns out desired vegetation.
