For established landscapes, broadcast evenly around drip line and incorporate lightly into top 1-2 inches of soil or mulch. Water deeply after application to move nutrients into root zone. For container plants, reduce rates by 25-30% to account for limited soil volume and increased leaching. Reapply in fall for evergreens and plants with extended growing seasons in zones 8-10. Avoid application during drought stress - water plants thoroughly before fertilizing. For newly planted specimens, wait 2-3 weeks after planting to allow root establishment before first application. Combine with Root Booster at planting for accelerated establishment, then follow with SR-18-5-10 for long-term nutrition.\u003c\/p\u003e\n\u003ch3\u003ePro Tips for Maximum Results\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eApply in early spring for season-long feeding - one application handles the entire growing season\u003c\/li\u003e\n\u003cli\u003eWater thoroughly after application to activate controlled-release coating and move nutrients into root zone\u003c\/li\u003e\n\u003cli\u003eSpread evenly around drip line, never pile against stems or trunks to prevent burning\u003c\/li\u003e\n\u003cli\u003eBury under mulch if you have pets or children for safety - it works just as well underground\u003c\/li\u003e\n\u003cli\u003eChoose the 4-Pack Bundle (Gardener's Special) or 8-Pack Bundle (Landscape Pro) for maximum savings on larger projects\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is 18-5-10 fertilizer used for?\u003c\/strong\u003e\u003cbr\u003eIt's a balanced NPK fertilizer formulated to support steady vegetative growth, strong roots, and overall plant vigor. It's commonly used as a long-lasting plant fertilizer for shrubs, landscape plants, trees, perennials, and ornamentals. The 18-5-10 ratio provides optimal nitrogen for foliage growth, phosphorus for root development, and potassium for overall health and disease resistance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow long does SR-18-5-10 fertilizer last?\u003c\/strong\u003e\u003cbr\u003eAs a controlled-release fertilizer, it provides plant nutrition for up to 10 months depending on weather, watering frequency, and plant demand. The timed-release technology delivers nutrients gradually instead of all at once, reducing the need for frequent reapplication during the growing season. One spring application typically feeds plants through fall.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan SR-18-5-10 be used as controlled-release fertilizer for trees?\u003c\/strong\u003e\u003cbr\u003eYes, it works excellently as controlled-release fertilizer for trees when applied evenly around the drip line. Keep granules 4-6 inches away from the trunk and spread evenly rather than concentrating in one spot to prevent damage. Water after application to help move nutrients into the root zone where trees can access them.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill this burn my plants?\u003c\/strong\u003e\u003cbr\u003eNo, when applied correctly. The controlled-release coating prevents nutrient dumping that causes burning with fast-release fertilizers. As long as you spread it around the drip line (not piled against stems) and water after application, SR-18-5-10 is extremely safe and won't burn plants.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much does one bag cover?\u003c\/strong\u003e\u003cbr\u003eThe 1 lb bag (16 oz) feeds approximately 32 one-gallon plants, 6-8 two-to-three-gallon plants, or 3-4 five-to-seven-gallon plants.

This ensures plants receive nutrients during their active growing season. In zones 8-10 with extended growing seasons, you can make a second application in fall for evergreens and plants that grow year-round.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I use this on vegetables?\u003c\/strong\u003e\u003cbr\u003eWhile SR-18-5-10 works on vegetables, it's formulated specifically for ornamental shrubs, trees, and landscape plants.

If you have small children or pets, simply bury the granules under soil or mulch after application - it works just as effectively underground and eliminates access concerns.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is this better than liquid fertilizer?\u003c\/strong\u003e\u003cbr\u003eSR-18-5-10 feeds for up to 10 months from one application, while liquid fertilizers require reapplication every 1-2 weeks.
