Nutsedge: The Superweed
The best way to describe nutsedge is “superweed.” Unlike other broadleaf weeds, this sedge has a robust root system made of nut-like tubers called nutlets. The nutlet stores a high amount of energy for the nutsedge to use in its lifecycle. With their grass-like leaves, sedges can be difficult to distinguish within the lawn at the beginning of the growing season. In the hot, humid, sunny days of summer, however, it grows faster than most grasses and even begins to flower. It is easy to distinguish only a few days after mowing by the lighter green leaves shooting up quicker and taller than the grass surrounding it.
Mowing Tips for a Healthy Lawn
Proper mowing is the most important cultural practice you can do for a healthy lawn. It is important to state that mowing isn’t necessarily something we have to do to keep the lawn healthy. In reality, the natural growth habit of tall fescue is for it to grow several feet tall. We force it to be 3 to 4 inches high because we want that manicured look and because of all the other benefits we receive from a well-manicured lawn, including pest control. With that said, it stands to reason that there are certain things we have to do to minimize the damage we cause when we mow. Here are some mowing tips and “must do’s” when maintaining lawn during the growing season.
The best way to control crabgrass is to kill it before it grows with a pre-emergent herbicide, but when is it too late to treat? Unfortunately, there’s no single definitive answer to this question. The short answer is to apply it before the crabgrass has a chance to germinate. The longer answer is that it depends on the weather and which pre-emergent is being used. Pre-emergent herbicides work by creating a chemical barrier that kills the crabgrass when it germinates. Some pre-emergent products provide some post-emergent control as well. Determining when a seed germinates depends on many variables in the environment. For crabgrass, the biggest variable is temperature. Crabgrass only germinates at sustained soil temperatures above 57°F at a one-inch depth. The best way to track the soil temperature is with growing degree days (GDD). Because it is tough to track soil temperatures without specialized equipment, we can use air temperature. Air temperatures will usually need to be at around 50°F for 200 degree days for germination.

It’s that time of year, again. The weather is getting warmer, the grass is growing almost faster than you can cut it, and just when the grass starts to get nice and green, these little white feathery things show up out of nowhere! So, what are they called, and how can you get rid of them? (more…)
We get questions about spring lawn seeding every year. Many people, especially grass seed producers, recommend it, but it may not be the best option. While we can aerate and overseed in the spring, we recommend waiting until the fall for two main reasons. First, the weather in the spring and summer is challenging to seed and new grass. The spring weather can be unpredictably warm or cold, and grass seed needs soil temperatures for germination that are far from guaranteed. Additionally, the grass is in the early stages of growth during the heat of the summer, leaving it susceptible to disease and heat and drought stress. For these reasons, spring lawn seeding is less successful than fall seedings. The second reason is weeds, namely crabgrass. Crabgrass is the most important weed to control throughout the lifetime of the lawn, especially in the first few years of treatment. Because of this, our first application of the year includes a pre-emergent crabgrass control which stops the crabgrass seeds from sprouting by creating a protective barrier of herbicide that kills the crabgrass before it can reach the surface of the soil. It also prevents desirable turfgrass from sprouting, making seeding and crabgrass control almost mutually-exclusive. (more…)

It’s a beautiful day here at MRW Lawns, Inc. The low humidity and nice temperatures allow for some good drying after the torrential storms on Saturday. Enjoy it while it lasts, and be sure not to let the lawn get too tall. Now, it is important not to mow when the soil saturated, but try not to let it get too tall, and mow it twice if you have to to remove excess growth (for example; the lawn gets to 7″ and you want to mow it to 3″).
