The big thing is to keep up with watering and to mow as needed. Also it’s too hot to treat for weeds broadly like some of my posts talked about in the past. If you treat for weeds use a hand held sprayer and go directly at the couple weeds you are targeting. It’s also too hot too push your lawn by using fertilizer. This is a risky time of year to place down chemicals and you risk burning your lawn, so be aware of that. This time of year I just put down a natural fertilizer called milorganite. It just feeds microorganisms that produce the fertilizer by feeding on the milorganite and has no issues of burning the lawn. I also treat for bugs as needed, at least every other month and I have had good results with that. I also still place down a pre-emergent fertilizer every other month and that helps keep the weeds down to begin with.
Back to the watering. Make sure your lawn gets an inch of water a week to keep it green and healthy. So weeks we get rain is awesome and ones we don’t, make sure to water. If using an irrigation system make sure to watch for hot spots along sidewalks or places where the soil is poor in the lawn. Just hand water a little extra there to counter act that.
So if you followed my last post you have treated your lawn with an herbicide and now you have a lawn full of dead weeds with some grass underneath. Wait at least three days for the weeds to die and then it’s time to pull out your lawn mower.
If it’s your first time mowing for the year it’s a good time to get your lawn mower blade sharpened. I just take mine off and use a file but there are people out there that will professionally sharpen it for a small fee. Do whichever works for you. Next adjust the height of your mower deck. The rule of thumb is to not mow more than 30% of your lawn at once. So if you haven’t mowed in a while you might take a few different mowings to get to your desired height. Right now my lawn is looking healthy at 2 inches and in the summer I let it grow a bit longer to 2.5 inches. I find that helps my lawn retain the moisture in the soil better in our hot summer months. Experts in our area recommend as long as three inches for Bermuda. It will take you a little experimentation to see what works best for your lawn along those lengths. One small note: I don’t recommend 1.5 inches or shorter past spring. It’s very hard to keep that from burning up at that length. With this mowing I recommend bagging the clippings as it will have seeds from the weeds that you don’t want to put back in your lawn. On a regular basis I use the mulching function on my mower and I credit that as part of what helps keep my lawn and soil healthy.
Another thing worth mentioning is how often to mow. In spring it starts growing pretty quick so you normally can’t go more than two weeks without needing to mow or else ending up mowing too much off at once. This is one of the more common mistakes I see in our area when someone mows every other month and their lawn struggles because every time it gets cut it loses more than half of the blade. Cutting on a more regular basis is much healthier for your lawn. If you can’t meet that schedule, get a lawn service or neighborhood kid to mow it for you. As another alternative SAWS offers coupons for removing parts of your lawn to replace with native plants, pavers, and other durable coverage. Check the SAWS website for details on that.
As a note at the bottom here, you might have heard of somethings called scalping before. With Bermuda it goes dormant in the winter and becomes a nice gold/brown. In the spring that dead grass just gets in the way. I normally scalp my lawn at the end of February to the beginning of March. I normally do the mowing in two runs to get it all. I bring it down to 1.5 inches on the first run and then 1 inch on my follow up mowing as the shortest my mower can safely mow the lawn. I bag all the clippings from scalping as the clippings would be too thick and have little value back in my lawn as such dead grass. If you missed scalping earlier I would try mowing half an inch lower than normal this cutting which will get you some of the same benefits but won’t be as tough on your lawn as things seem to already be heating up quickly.
So maybe you have neglected your lawn for a bit and want to start taking care of it. What are some things you can do to start getting it into shape?
Apply a pre-emergent herbicide to prevent weeds from germinating. Think of this as part of your defensive plan for your lawn. Scotts Halts (Amazon & Lowes)and Green Light Amaze (Amazon & Lowes) are good herbicides for the job. I have also found corn gluten meal (Amazon & Lowes) to be a good natural product for the job.
Mow your lawn, even if it’s just the weeds growing now and not the grass. Mowing your lawn to a proper height will keep the weeds from getting large enough to seed and will act as another layer of defense for your lawn. Mow frequently enough that only one-third of the grass blade is removed at every mowing. Mow St. Augustine and Bermuda to 3 inches tall, zoysia to 2 inches tall and buffalo grass to 5 inches.
Go on the offense by pulling already established weeds or using a post emergent herbicide. The important rule I have found with spraying a post emergent like Spectracide Weed Stop is to make sure to only apply it when it when it will be between 45 degrees and 90 degrees and you have plenty of sun. I have found it to be barely effective of cool overcast days but highly effective on warm sunny days. Make sure to spray it primarily only on weeds and make sure to test on a small portion of your lawn to ensure the brand doesn’t adversely impact your grass. Also be aware post emergent herbicides don’t work on everything so pulling might still be required.
Other steps might include adding in mulch or fertilizers to your lawn but I find the first three steps the most important to start getting a handle on things.
We have had a lot of rain which has made it difficult to mow lawns on a regular basis. The first thought of many might be to jump out and cut the lawn as short as you can to make it so it takes longer to mow again. That would be a mistake. It’s just a lawn-mowing myth that says the shorter you mow grass, the less often you’ll have to cut it. That misguided concept lays a foundation for a problem-prone lawn. Grass that’s cut too short is more susceptible to weed invasion, drought and heat damage. In addition to that if you cut off too much at once stresses the lawn and makes it easier for weeds to come in. The general rule of thumb for mowing is to never remove more than one-third of total grass blade length at a single cutting. This might require additional cuttings on your part when it clears up to get to your desired height but it will help keep your grass healthier. As far as heights you generally mow St. Augustine and Bermuda to 3 inches tall, zoysia to 2 inches tall and buffalo grass to 5 inches. There might be some variation with lawns during the year. For example, I mow my Bermuda lawn in stages down to 2 inches in early spring but let it grow out to 4 inches by summer and that is where it seems to do best in the heat. In the month of October, you should also apply a winter fertilizer, which will be utilized by the lawn for winter hardiness and a fast green-up in the spring. I hope these tips will help you in maintaining a beautiful lawn.
