Practical tips on fertilizing, weed control, and keeping your lawn healthy — written by Terrill Unruh.
When to Spread Crabgrass Preventer
People often ask when they should spread crabgrass preventer. That is a hard question — if we have a warm early spring it needs to be put on earlier. You have probably heard the rule of thumb: put crabgrass preventer on before the Red Buds bloom. That always seems a little on the late side. If you have a protected area on the south side of a brick building, for example, that area may germinate well before the Red Buds bloom because the soil temperatures will be much warmer there. A good time would be after you mow your grass for the first time, around the middle of March.

Crabgrass Preventer: The Split Application Method
We spread about half of the crabgrass preventer needed for the year in the first application, then spray the remaining half with the next visit. The reason we do this is to try to get better control on the crabgrass. It only takes about half the yearly rate to stop the seed from germinating — the remaining half stays in the soil and keeps all the seeds that would germinate throughout the year from sprouting. So we do the split application in case we leave any skippers — we are less likely to skip the same area twice. It gives us about 6 weeks longer control.

Armyworm Invasion: Identification & Treatment
Armyworm damage almost looks like grubworm damage, but when you pull up on the grass it is firmly rooted — whereas grubs eat off the grass just under the dirt, and pulling on the grass causes it to come up like sod with dirt attached to the roots. Armyworms tend to do a lot of damage in a short amount of time. They eat the grass blade down to the crown, but they do not necessarily kill the grass if treated promptly. If you want to spray, Tempo or Talstar works very well.

Early Spring Lawn Care: Soil Health & Mycorrhizae
If we only spread fertilizer we are doing nothing to improve your soil. Fertilizer is only feeding the grass. If your soil is healthy, your grass will look good with less water and less fertilizer. We spray a product called Sanctuary that contains Mycorrhizae — beneficial bacteria that feeds the microbial activity in the soil. The more microbes, the healthier your soil and thus healthier grass. We also use a micronutrient package that feeds your lawn with minerals to help it stay healthy through the hot part of the season.

What Was the Late Freeze Good For?
When is the best time to do spring cleanup and prune our bushes, roses, and grasses? It seems like our main purpose for doing it early is looks — keeping up with the Joneses. But often there is no thought given to the health of the plant. Knockout roses that were pruned early can freeze back significantly from a late frost. And ornamental grasses are susceptible too. That unsightly trash from last year — the old vegetation and fallen leaves — is actually a protector for the tender new shoots growing underneath.

Native Grass Work at Flint Hills National Golf Club
Flint Hills National is removing approximately 2,000 trees to remedy overcrowding — a significant undertaking that changes the character of parts of the course, opening up sight lines and allowing native grass areas to thrive. We've been reseeding areas where trees have been removed and where drainage work has disturbed the ground. The Flint Hills region of Kansas is one of the last remaining stretches of tallgrass prairie in North America, and we take that heritage seriously.

Solu-Cal and Soil pH: Why Your Fertilizer Isn't Working
From taking many soil samples in the area we find that the pH of the soil is often high — we don't think we have ever had one that is too low. The remedy is Solu-Cal, an enhanced gypsum product that helps neutralize pH. If soil pH is too high, your lawn is not able to efficiently use the fertilizer we spread. Some lawns begin to look peaked a few weeks after fertilizing. This is often a sign of pH imbalance rather than a lack of fertilizer. Solu-Cal targets the root of the problem instead of just adding more product.

Defendor: Stopping Dandelions Before They Bloom
Defendor specialty herbicide is a post-emergence product effective at pre-emergence timing — designed to perform in cold weather when other herbicides can't. It prevents dandelion bloom, which is huge: if we can keep the dandelions from blooming, then we can come back on the next application and kill the plant before it can spread any seed. Defendor is also very effective on clover, which has become increasingly common in Kansas lawns in recent years.

Winter Lawn Care: What Your Lawn Needs in the Off-Season
Kansas winters can vary wildly — some are wet and cold, others dry and mild. Either way, your lawn still needs some attention. If you have a self-draining sprinkler system, it's beneficial to water on days above freezing. Fescue is semi-dormant in winter and benefits from some moisture, especially during dry winters. Don't be surprised to see us applying the first crabgrass preventer in January — there's no downside to getting it on early when weather allows.
