Planttype’s walnut and basswood ply markers are more than just labels — they’re designed to nourish your garden. Each marker is carefully soaked and dried three times in our unique nutrient-rich solutions, ensuring the wood absorbs and stores nourishment deep within its structure. Once placed in the soil, the markers act as slow-release spikes, gradually delivering essential nutrients every time you water. This helps strengthen root growth, improve soil health, and support thriving plants without the need for synthetic fertilisers.
