- Have 18 34 12 lesson it’s July 28 can I apply on lawn

- 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.
