NOS nitrogen stabilization system is fully incorporated to ensure that every dollar you invest in nutrition is maximized.

Q&A

What setting do i use with a Scotts rotary spreader?: 5-5.5 will apply 4-5 lbs per 1,000 sqft. You can view spreader settings here: https://lawnsynergy.com/pages/spreader-settings

Have 18 34 12 lesson it’s July 28 can I apply on lawn: Yes, you sure can!
Hello. I just purchased a bag of Lesco Starter Fertilizer 18-24-12 with OPTI45. Application is 4.2 lbs per 1,000 square feet. Could I put this down every 30 days? or 45 days?: Every 45 days would be ideal if you have a phosphorus deficiency. Please perform a soil test first.
Can this be used in conjunction with lawn synergy muriate of potash and triple super phosphate?: It’s going to be an excessive amount of potassium and phosphorus. Suggest waiting about 6 weeks before applying more.
