AgriLawn's Seasonal Weed Control and Fertilization Blog
The freezing temperatures and precipitation that we have been experiencing lately can have a bigger impact on your turfgrasses than you might think. Let’s briefly explore what effects these conditions can have on your lawn in both the short and long term.
As we get closer to the hot summer months, risk of heat exhaustion and heat stroke increases. Everyone knows the temperatures in Oklahoma can be extreme. This year we have jumped past nice spring temperatures right in to the summer temperatures. With that in mind, AgriLawn is putting out a reminder to take extra precautions to help identify the warning signs of heat exhaustion.
The people of Oklahoma are no strangers to adversity. We see every kind of weather from hot to cold; from droughts & winds that bring wild fires to flooding; and of course don’t forget tornadoes! Over the last few years, we have even started experiencing earthquakes!
If you had to wonder where we’ve been at some point recently… Bob Dylan’s lyrics ring especially true for us here at AgriLawn this year. We usually face some early season weather challenges and setbacks but Wow!
Over the last 90 days it looks like we’ve received just barely close to a half inch of rainfall and no snow or ice to speak of here in and around Oklahoma City. While missing out on the snow and ice I can agree is a good thing, missing out on the moisture is not, when it comes to our lawns and landscapes.
Winterizing the lawn is all about preparing it for the cold months ahead and is an important last step each season. Even though everything slows down near and above the soil surface there’s still plenty going on underneath the soil. Providing the lawn with a late season shot of potassium benefits it greatly.
If you need help getting this chore done this year give us a call. Late summer / early fall is the best time to seed the cool-season grasses (fescue, perennial rye) here in Oklahoma. Seeding now allows healthy maturation of these grasses before becoming overwhelmed with spring and summer heat. Really, this is why we over-seed to begin with – to replenish fescue stands that become thin as the summer heat and other stresses wear them down.
A few weeks ago some parts of town were dealing with extraordinary amounts of May/June Beetles. It was a buzz on social media and even a couple of news reports covering this. May/June Beetles are the clumsy flying, sticky legged, bright light attracted big brown bugs that seem to spend more time on their backs than they do in the air.
As we edge further into the hot summer months, risk of heat exhaustion and heat stroke increases. Everyone knows the temperature in Oklahoma this time of year can be extreme. With that in mind, AgriLawn is putting out a reminder to take extra precautions to help identify the warning signs of heat exhaustion.
Testing the soil not only provides information regarding the macro nutrients present in the soil it also more importantly reveals the soil pH. Soil pH is the measure of the acidity vs. alkalinity of soil using a scale of 1.0 to 14.0 with 7.0 being neutral. Here in Oklahoma turfgrass and many landscape plants perform best when the soil pH is slightly acidic (between 6.5 and 7.0). When the soil pH is too high or too low (further away from neutral) it becomes increasingly more difficult for turfgrass and landscape plants to utilize the nutrients available from regular fertilization.
You may have noticed the fall webworms already at it this summer. These nuisance pests affect various trees in our great state, most commonly persimmon, pecan and walnut. With fall webworms out this early we could see infestation of oak, birch, sweet gum, sycamore and red bud trees as well this season.
It is not uncommon this time of year to see some bermuda grass lawns riddled with circular dead spots. These spots are actually the remnants of damage caused to the bermuda grass in spring and the previous fall from a soil disease known as Spring Dead Spot (SDS).
With the fair weather there has been opportunity to get out and start the early season yard work. You’ve probably noticed many homes and businesses having done some selective pruning/cutting of landscape plants, leaf removal and perhaps even mowing already. If you’re itching to get out there and mow and clean the yard up, have at it! I would simply advise not to go too low with the mowing yet.
Where are the weeds!? Approaching only 30 days left before the official start of spring (March 20th) and while we are seeing increasing early spring weed activity each week we have yet to see the typical weed explosion we usually experience this time of year. The biggest reason for this is the current lack of soil moisture
