Is lime a covalent compound?
Your lawn company should know if an application of lime is needed. If you live in an area which receives a fair amount of rainfall annually, your soil will more than likely be acidic, and an application of lime will sweeten the soil. The temperature has nothing to do with when an application should be done, if in fact your turf needs it at all. The only problem I have with your service doing it in the spring is that lime takes about 3 good months to become available to the lawn. Applications are usually done in the late fall to early winter for best results (when dolomite lime is used). This way in the spring, when the turf begins to come out of winter dormancy, it will have the needed PH change and will have benefited fully from the application. If however, a calpril or pelleted lime (the best) is used, it will become available much quicker than dolomite and a late winter or early spring application is ok to do. If you are unsure whether your lawn service knows what they are doing, you can contact your county dept. of agriculture and they can tell you exactly how much lime is needed in your area, as they keep annual statistics on this according to the rainfall amounts.... Hope this answers your question... Good luck!.... ...Billy Ray
You need to take a soil teast every three years to tell you what it needs. If you just add lime to be adding it when it is not needed you are adding acidity to it and grass doesn't like acid soil. A soul teast wil l twell you if you need Lime-Rock Phosfate-Potash. On the fertilizer bag lets say iy says 12-12-12 That is 12% Lime 12% rockphosfate 12% potash. The three ingreadiance in all soil.
You don't need to ever add lime to your lawn. It will grow even better without all those harsh chemicals. To much lime will damage your lawn. The lawn co just wants to make $ off you.
I can relate, have had a lawn for the last 5-plus years. I went to a good local nursery and asked their advice about caring for the particular type of grass that I have--St. Augustine. They recommended a particular type of fertilizer that was developed by a very good agricultural university in my state. They can also recommend the height that you should keep it at different times of the year, depending, again, on what type of grass it is. Also, they can tell you what to look for in terms of any diseases or weeds, etc. that can affect how your lawn grows. Nursery folks are always happy to share their knowledge and experience with you.
You should lime as often as a soil pH test indicates it's needed. Don't take the lawn company's word for it. They are looking for work.
