Avoid all weed control products that contain fertilizers. The fertilizers in these products are designed to release slowly with several watering cycles. If you have a fertigation system injecting/proportioning fertilizer into your irrigation water, the result can be severe burning of your landscape. Fertile Earth, Fertigator, and EZ FLO all recommend using bio stimulants/organic supplements regularly with your fertigation system. Fertile earth and Fertigator have these already blended into their formulations. These supplements will act as a catalyst for the fertilizer in your weed control and force it to release immediately burning the landscape.

The best method for weed control is landscape fabric combined with drip irrigation in your planter beds. The lawn will get stronger each year as the root system develops and chokes out the weeds. Start each year off with a low "N" high "P" & "K" formulation to get the best results.
