|I HAVE A LAWN WITH ST AUGUSTINE AND ANY OTHER GRASS THAT WILL GROW. THE SOIL IS RED CLAY AND I HAVE AN ACRE OF YARD. I WANT A FERTILIZER THAT WILL WORK ON EVERYTHING AND NOT BURN. PLEASE HELP! THANK YOU, JIM.|
I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
The key to not burning the lawn is to not overapply fertilizer and to not use a fertilizer with weed control added now that temperatures are above 80 degrees. Fertilize with no more than 1/2 to 1 pound of nitrogen in spring after you have mowed the grass twice, and again in fall (around late October). Apply a product with a 3-1-2 ratio of nutrients as this is roughly the ratio of nutrients grass takes in. So, for example, if you purchased a 15-5-10 fertilizer (15% nitrogen), you would apply about 7 pounds per 1000 square feet (1 pound / .15 = about 7). If you purchased a 21-7-14 fertilizer (21 % nitrogen), you would apply about 5 pounds per 1000 square feet (1 pound / .21 = about 5).
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
