Osmocote Smart-Release Plant Food Plus 2lb
by Osmocote
Osmocote's Smart-Release Plant Food Plus is the gold-standard slow-release granular fertilizer for container plants, with a unique resin coating on each granule that controls nutrient release over 6 months based on soil temperature. The 15-9-12 NPK formula (with 11 essential micro and macronutrients) feeds plants at a calibrated rate — warmer temperatures accelerate release when plants are actively growing, and cool temperatures slow it when plants are dormant. One tablespoon per gallon of container volume is the standard dose.

- 6-month feeding window eliminates frequent fertilizing
- 11 essential nutrients including micronutrients often missing in basic fertilizers

Worth Knowing

"Osmocote Plus is the single most recommended fertilizer among professional container growers for good reason — the temperature-controlled release mechanism is genuinely clever engineering. For someone who wants consistent plant health without weekly feeding schedules, a spring application at potting time will carry most plants through the growing season. The only caveat is that resin coatings are an environmental concern; use liquid fertilizer for small, easily-monitored container quantities."
