I applied a 32/5/8 50%scu plus iron in early July. Then the nasty drought set in. Now, since the rains have returned, the lawns are very green and growing so fast that they need to be cut every 3-5 days. I believe the fert is just now begining its release cycle. I have not been there for 2 months and the weeds are really growing like mad. I need to treat. I decided to apply weed control and CHELATED IRON at 2 oz/1000. My customers are extremely pleased with the treatment. I am aware that the color will not last as long as fert, but most every lawn is GREEN right now. Even the ones that are not fertilized. I am seriously considering using IRON instead of fert in the April & Sept. treatment every year. I have noticed the same problem in normal years. The lawns are very green in those months and mowing becomes a real problem. What do you think?
