As dedicated horticulturists, we prioritise the use of environmentally responsible and, whenever feasible, organic fertilisers. Our selections are not only kind to the environment but are also formulated to be safe for children and pets to walk on post-application. That said, while they're safe to walk on, no lawn care product is safe for ingestion, so care must be given to ensure pets do not eat the granules or grass until at least the lawn has been fully watered in (by rain or by you) and fully absorbed.
