At that cutting height, you want as little fertilizer as possible ! Use something with iron , to provide green without excessive top growth. 'Milorganite' is perfect for greening turf without burn and surge growth.

You can also use a mostly slow-release fertilizer like 39-0-0 sulfur coated urea or Lesco 21-4-11. Milorganite has 40% water soluble N, whereas Lesco 21-4-11 for example is 90% slow release.

That Lesco analysis looks pretty good- but its been my experience- that sulfur coated urea releases to quickly in warm weather. I did an experiment with coated urea - using it in the winter (southern Calif.) , and it even released quite a bit in cool weather. (45 to 50 degree nights)

Thanks. Is a slow release fertilizer like Lesco less likely to burn the lawn?

Yep, you really have to watch the water soluble factor. A lot of fertilizers claim to be slow release, but you look at the fine print, and they have way too much quick releasing nitrogen. Its ok in certain situations, but a well established lawn in decent shape, will usually not need quick nitrogen in warm to hot conditions.

Thanks, Lawniac and everyone. That helps a lot. Anything else I should put down other than the Lesco? Or just water regularly and let it do its job

Nobody has the 21-4-11 Lesco in Memphis and can't buy it online. Anyone used Coron 28-0-0?

You have to go to SiteOne.

Yes, SiteOne in Memphis doesn't have it. Two people I spoke to didn't even know much about Lesco. SiteOne just started carrying it? Pretty sure that's what they said
