Spring is upon us, which means we are approaching the optimal time of year to set lawns up to take on summer stresses.


Spring is upon us, which means we are approaching the optimal time of year to set lawns up to take on summer stresses.

April 15th average high temperatures are as follows in various locations:

Toronto: 12°C (53°F)
Minneapolis: 58°F
Denver: 62°F
Indianapolis: 62°F
Philadelphia: 65°F
Nashville: 71°F

What does this mean for fertilizer, preemergent, and postemergent applications?


Northern grasses like Kentucky bluegrass and tall fescue prefer temperatures between 60°-75°F. As indicated by the growth curve above, we have at least one to two (or more) months to take full advantage of growth potential before the onset of summer lawn stresses like heat, drought, insects, and diseases. Between now and then, our PhD developed agronomic programs are designed to get lawns as healthy and strong as possible to withstand these stresses. Our specialists execute the agronomic program according to scientifically developed and established Application Best Practices to apply the proper amount of fertilizer to strengthen roots and maximize overall lawn thickness & color.


Spring preemergent weed control applications combined with proper mowing and watering by the customer significantly reduce summer weed problems, especially annual grassy weeds like crabgrass. Similar to how changing your oil in your car and other routine maintenance is much easier than taking care of costly auto repairs due to neglect, preventing problematic annual grassy weeds is much easier than trying to control them once they are established. Remember that seeding is not recommended in spring because of the effect preemergent products have on them, as well as the short window to get seed germinated and strong enough for the summer.


Spring postemergent weed control applications give us the opportunity to satisfy customers by taking advantage of typically adequate soil moisture and temperatures. Fortunately for us and our customers, the spring conditions weeds prefer for growth are the same conditions which make weed control applications very effective. Rivaled only by fall, spring is an excellent time to control weeds, especially hard to control species like wild violet and ground ivy (a.k.a. creeping Charlie).

Lawn care in the spring is all about strengthening the lawn to take on the summer and controlling weeds during favorable conditions. Taking advantage of this opportunity now will lead to healthier lawns and satisfied customers in the summer.
