A Tough Season for Turf!

The fall season provides a great opportunity to give your lawn some TLC after the stresses of summer.

This past year was one of the most difficult I can remember for keeping lawns looking good throughout the growing season. Weather certainly played a huge role in this, as – depending on where you live – you either had to deal with an overabundance of rainfall or a major lack of precipitation. Due to a number of reasons I will address below, many lawns are looking a little beat up as we enter into fall. The good news is you still have some time to get that lawn back into shape before the cold weather sets in.

One the most difficult issues we dealt with this year was crabgrass. Unfortunately, even lawns that were treated with pre-emergents were not safe from crabgrass invasion. Weather conditions (i.e. the heavy rain or dry weather mentioned previously) had a major impact on the efficacy of pre-emergent applications this spring, as it helped break down the protective barrier at a faster rate, allowing crabgrass to germinate. As a result, crabgrass was seen almost everywhere and created quite a bit of work and cost to most lawn care operators who were forced to do post-emergent treatments to try and get rid of the crabgrass.

We also saw a large number of insect infestations across the country this past growing season. From chinch bugs and bluegrass weevil in the north, to armyworms in the Tennessee Valley and tropical sod webworms in the far south, almost every region across the U.S. was faced with some form of unwanted pest.

Last but not least, we received many calls in our Weed Man offices related to turf disease that led to thinning turf, unsightly patterns in the lawn and discoloration.

Help Your Lawn Recover

If you’d like to get your lawn back into shape and help it recover, fall is the perfect time to give your lawn a good feeding and help tackle any ugly bare patches. During the cooler weather of autumn, turf grasses tend to use the nutrients from fertilizer to grow roots and fill in bare spots, which is part of the reason fall provides such an optimal window for fertilizing. In the spring, on the other hand, fertilizer nutrients are mainly used for top growth in the leaves and shoots.

Fall fertilizer contains two key ingredients: nitrogen and potassium. Both will help stimulate and repair your grass. Nitrogen aids in plant growth and helps keep grass looking green and healthy. Look for fertilizer that has a high amount of available nitrogen in a slow release form (like Weed Man’s exclusive granular fertilizer!), so that it feeds the lawn slowly, as the plant needs it.

Potassium (potash) is equally important in the fall, as it plays a vital role in healthy turfgrass development and is second only to nitrogen in the amount required for lawn growth. Potassium enacts a protective mechanism in grass plants, hardening off cell walls to fight back against damaging factors. Turfgrasses that are deficient in potassium are more prone to injury during the winter months.If possible, try to mulch your grass back into the lawn when cutting, as this will help put nutrients like potassium back into the soil as the clippings break down naturally.

Keep in mind that fall is also a great time to seed the lawn, as ground temperatures are still warm and benefit from plenty of dew at night (this will help keep the seed moist). You should have an easier time getting the seed to germinate at this time of year, which will reinvigorate any bare spots that need repair. For larger areas, aeration combined with an overseeding will really help that neglected lawn come in green and hardy next spring.

Drought Damage? Time to Start Thinking About Fall Seeding!

Soil with seed and new grass.

It’s hard to believe we’re already at the end of the August. Every year at this time I always ask myself “where has the summer gone?” Typically by now we start to see some cooler temperatures, especially at night, which does help the turf out immensely. That being said, nothing can help a lawn like cooler days and rain, which we are still waiting for in some areas.

My theme for the past number of posts has been focused on the hot, dry weather the north and northeast have been experiencing this season, especially compared to other areas like the midwest where they have had more than normal amounts of rain.

For those that have had to deal with drought and possible watering restrictions, your lawns may not be looking very good at the moment. Not to worry, now is the time to start thinking about how to get your lawn back into tiptop shape. With September’s cooler temperatures and more frequent rainfall, there is a great opportunity to make huge improvements in your lawn before winter hits. Most people don’t realize that the period between September and early November is the best time to seed your lawn – even better than in the springtime! This is because you often get too much fluctuation in temperature (both air and soil) during the spring season, not to mention excessive rainfall. This makes it difficult to get optimal seeding results.

Regardless of the time of year that you seed, there is one constant requirement: water. Turfgrass seed requires moisture for up to a month, depending on the type of grass seed used. If the seed dries out at any time after it has become moist, it will die. The majority of homeowners make the mistake of putting seed out and not watering it…and then wondering why they didn’t see any results.

There are many benefits of seeding in the fall. Firstly, it will help thicken up any areas that may have been thinned out during the summer months (like during the drought I mentioned previously). Another big benefit of overseeding is that it introduces better cultivars to a lawn that may have been planted or sodded 20+ years ago. Every year, seed growers improve their grass hybrid species to have better drought and disease tolerance than the previous years. Overseeding is a great way to help introduce these more tolerant species of grass to your lawn. The result is fewer turf diseases and a smaller water requirement down the road.

While there are many different ways of seeding your lawn, Weed Man will typically do it in combination with aeration or by using a split seeder. If the lawn has had major drought damage, split seeding is the best way to renovate the lawn. Because seed requires some soil contact, combining overseeding with aeration or split seeding is a great way to make that happen. I’ve seen homeowners just throw seed out over their lawns without thinking about soil. This is a waste of money, as it is unlikely that much seed will germinate without soil contact.

Summer Drought & Your Lawn

The summer drought conditions this year have been pretty severe in a number of areas and we’re only into the early part of July. With it being so dry in May and June, it can’t help but have an effect on your lawn now and into the fall.

In March I wrote a blog that started with “If the weather predictions come to fruition this year due to the strong El Niño, it looks like we will have a drier and warmer-than-normal summer in 2016.” So far, that is exactly what is happening in a lot of areas in the U.S. The past few years (at least in the eastern parts of the U.S.) we have been pretty lucky in that we had fairly regular rainfall and cooler summers. So it may come as no surprise that we were due for some drier, warmer weather with some severe drought. So what can you do to help the lawn through this hotter and drier weather?

As I mentioned in my March blog, one of the things you could have done to prepare for the hot and dry summer was getting your lawn as healthy as possible in the spring prior to having to experience the summer heat and drought. “You definitely don’t want to skip any fertilizer applications this spring or early this summer as the lawn will need it. Fertilizer is going to be very important in setting up the lawn to withstand the stress of a hot summer by giving it the key nutrients it needs to help it stay healthy when its under stress.”

That being said if you are watering your lawn through the summer and keeping it green, the lawn will still need to be fertilized as it will utilize those nutrients to maintain its healthy state. If you decide not to water it and therefore let it turn brown, the amount of nutrients it requires will be a lot less and fertilizing it may be unnecessary. However, if you use a slow-release fertilizer, not to worry, those nutrients should stay there for the plant to utilize when you do get rain, which will encourage the grass to grow again.

Watering will have a big impact on a lawn’s appearance and proper watering is a must if you are going to keep the turf healthy until more regular rainfall occurs. Almost all grasses can withstand a certain amount of drought. For example, bluegrass can withstand drought for up to 6 weeks before injury. As you see in the picture below, this lawn had not been watered for quite a while and the lawn did not recover. The end result? Most of it had to be re-sodded that fall.

Remember that there are a lot of ways not to water your lawn and it is the most misunderstood practice for homeowners. The biggest mistake occurs when homeowners irrigate their lawn every day for 20 minutes (simply because that is the way most irrigation systems are set up), without realizing that this type of light watering can lead to shallow rooting and disease. Shallow rooting creates a weaker plant that is prone to environmental stresses, which can result in an increase in lawn diseases. Also, not allowing the lawn to dry out for a period of time can also increase the chance of disease. This ultimately leads to discoloration of the lawn and poor visual quality. Watering at night is often the biggest reason for the presence of disease on the lawn.

When it comes to watering your lawn and helping it look its best, water only when the lawn needs it and be sure to water deeply. Watering deeply in the morning when the lawn requires it will give your turf the opportunity to dry out and prevent lawn diseases in the process.

Mowing can also influence the health of the turf, so when it’s hot and dry out, it’s a great idea to mow your lawn as high as you can. The longer the turf is maintained, the healthier it will be, as it will have a much deeper rooting system. This deeper root system will better utilize underground water supply and find its own water and remain healthier overall.
