Potassium Boost 0-0-30 Lawn Fertilizer

I have a zoysia lawn in north central Texas. Our soil here has a lot of clay. Clay can and does bind up the potassium making it unavailable to the grass. My last two soil analysis have had potassium at 17. 5 of the desired range of 39-72. I purchased Lawn Synergy Potassium boost 0-0-30 to supplement my regular lawn fertilizer. It’s mid May and my Zoysia is starting to green up nicely as you can see in my photo and should continue to do so as it continues to warm up. I very pleased of the results of the application of Lawn Synergy potassium

So far so GOOD! Only time will tell.

No difference
