GardenPRO Shrub & Evergreen 18-6-12 Slow Release is a controlled release fertilizer for shrubs and evergreen plants, made for long-lasting, slow release garden nutrition.
This shrub and evergreen fertilizer is built around an 8–9 month formula that continuously nourishes plantings over an extended period. It’s a practical choice when you want steady, season-spanning support from one slow release product that’s specifically positioned for shrubs and evergreen plants.
Because it’s a controlled release fertilizer, GardenPRO Shrub & Evergreen is designed to deliver nutrients gradually over time rather than all at once. That slow release approach fits established landscape beds and foundation plantings where consistent nourishment matters, helping keep growth supported through the main growing season without constant attention. The product is also tied to spring timing, making it easy to plan your seasonal maintenance around a single, long-release window.
For shoppers who like clear, scannable facts, the formula is identified as 18-6-12, and the product is explicitly categorized as a slow release, controlled release fertilizer for shrubs and evergreen plants. If you’re maintaining hedges, mixed shrub borders, or evergreen-focused plantings, this is a straightforward fit when your priority is long-duration nutrition from a purpose-built shrub and evergreen fertilizer.
This is a good fit for gardeners and landscapers looking for a GardenPRO controlled release fertilizer that’s specifically aimed at shrubs and evergreen plants and designed around an 8–9 month slow release cycle.
Apply in spring for season-long, slow-release nutrition.
