The slow-release granules dissolve gradually, reducing the need for frequent applications while helping maintain consistent nutrient levels in garden beds, lawns and potted plants.

Because nutrients release over time, it’s best used at the start of the active growing season or as a maintenance feeding during warm months. Avoid applying during drought stress or when grass is dormant to prevent waste and runoff.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUse in spring at green-up or midsummer for maintenance\u003c\/li\u003e\n\u003cli\u003eFeeds for up to 8 weeks per application\u003c\/li\u003e\n\u003cli\u003eEven granules distribute nutrients consistently across the lawn\u003c\/li\u003e\n\u003cli\u003eCompatible with common turf varieties like St. Augustine\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use it on vegetables, flowers and potted plants?\u003c\/h3\u003e\n\u003cp\u003eYes—this balanced N-P-K ratio makes it versatile for many garden crops and ornamentals.
