There are many lawns currently in the spring green up phase that show streaks and patches of yellow turf. This is a common issue in North Florida when applications of nitrogen fertilizer are made before the recommended time of April 15. When turf is fertilized with nitrogen too early in the season it causes growth. Unfortunately, minor nutrients such as iron are not easily absorbed in cooler soils and therefore many lawns have yellow patches.

The easy solution to prevent this yellowing is to not apply nitrogen fertilizer before April 15. You are not getting your grass off to a good start by fertilizing earlier than this date. Research also shows that nitrogen applied before April 15 is often lost through leaching, leading to possible water pollution.

Patience is the key with lawn fertilization in the Spring.
