Knowing the signs that it’s time to fertilize your lawn is the most important thing to consider when it comes to dealing with different areas where the timing might be altered depending on the climate. If, for example, you just moved from Wyoming to Texas, the time when you should fertilize your lawn will differ greatly, since the temperature of the soil will differ depending on the seasons as well, and you might have to consider fertilizing and planting your first crops a little earlier than you might have normally thought best, and use the best lawn fertilizer available in your area.
As mentioned, the key factor here is the temperature of the soil. You’ll find a lot of gardeners telling you that the best time of the year is March or April, but in truth, it’s simply the time when the soil temperature reaches a certain value – more precisely, 55º Fahrenheit.
Scientists have noticed that this temperature is when nature begins its spring awakening, so it stands to reason that the soil will accept new nutrients better in this period. Fertilize too early, and the nutrients won’t get absorbed properly; do it too late, and you will have missed weeks of ideal sunshine and soil quality before the arrival of summer.
