I'm going to avoid the soil test and ask some questions about your general lawn care. How often do you water and for how long? How high/low do you mow and how often? What have you tried for weed control?

St. Augustine is an oddball grass; it's not quite centipede, which flourishes best in terrible environments, but it's also not quite as sensitive as Bermuda and most northern grasses to resources.

Plus you're in pretty good shape. P is perfect, OM is low, but that's the case in sandy soil in Florida. Certainly keep applying it, but don't expect any vast rise.

The one recommendation I would make is a little oddball. You're showing a very slight magnesium deficit. And I don't care about it--it's something to worry about next year, maybe. Ditto with the potassium, it's not far enough off to be a problem.

So let's go with Encap or Mag-I-Cal limestone--both very pure calcitic limes, ground very small to work fast.

Apply 3 pounds per thousand square feet of lawn sometime in March or April. If you can get it down before the front comes out of dormancy, so much the better, but it's not critical.

At the end of the season, apply another 2 pounds per thousand square feet.

I might-could tap some of the minor elements, but St. Aug won't care, and your iron levels are actually fine, so I'm ignoring those as well.

Thank you! Good to hear that I should be in pretty good shape as far as soil goes.

Dchall, I’ve been on here for a while and I’m familiar with your suggestions. I try to only water when I see drought stress, and put down 1” at that time. I try to mow weekly at the highest setting. I’m still battling weeds though. I went though a few weeks ago and hand-pulled all the dead crabgrass and some of the new weeds that are popping up. I plan to hold off a little longer (we’re in a little cool spell right now) and apply atrazine in two or three weeks before it gets hot.
