Crabgrass…in Early Spring?!

Every spring, our Weed Man franchises throughout the US field a fair amount of calls regarding possible Crabgrass infestations in home lawns.

To most homeowners, the thick-bladed grass that they’re noticing in their lawn must be Crabgrass. But since Crabgrass is an annual weed, what they are actually seeing (especially this early on in spring) is not, in fact, Crabgrass. However, in very rare cases, if there was no cold weather in the very southern states, the existing Crabgrass may not have died off.

In most cases, homeowners are misidentifying a weedy grass, such as Tall Fescue or Quackgrass. Both grasses are thick-bladed and look a lot like Crabgrass, so it’s not surprising that they presume that’s what they are seeing grow in their lawn.

Because Crabgrass is an annual, there are things that we can apply in the spring, such as pre-emergent weed control, that will help prevent it from germinating. There are also products that will help control it after it has germinated, although this method is a bit tougher to accomplish. Unfortunately, this is not the case for those weedy grasses like Tall Fescue and Quackgrass. Because these grasses are biologically similar to desired grasses, there really is no way to get rid of them other than digging them out or using a non-selective herbicide and re-sodding the area.

One other thing to keep in mind is that the germination of Crabgrass can vary, often starting in a sunny location, a full month ahead of other parts of the lawn that may be more shaded. A good way to know when Crabgrass is about to germinate is to use an indicator plant, such as the Forsythia Bush.  Keep an eye out for when the Forsythia Bush starts to flower, as this is a good indication that Crabgrass could be starting to germinate. However, in my opinion, the best way to tell is once you see the farmers in the fields planting their corn crops. This means the soil temperatures are just right and you can bet that the Crabgrass is going to be germinating as well.

A Cool Spring: A Cause for Concern

This spring season has certainly been more winter than spring. I’ve even heard it described as it being January 74^th today. One thing is for sure though…all of this cold weather is a cause for concern for our poor home lawns.

First and foremost, those states where southern turfgrasses are grown are the ones that concern me the most, as damage is likely to happen later this spring or summer. Thanks to the warmer weather those states experienced in February,  the turf came out of dormancy and started to green up and could have even been mowed a few times. But since then, with the colder weather making its return, lawns have entered back into dormancy or at the least, a semi-dormant state.

When this occurs, the sugars and carbohydrates don’t totally convert into the more cold-tolerant starches, like what typically happens in the fall just before the winter dormancy period. This can be quite stressful for southern grasses, such as Bermudagrass and St. Augustine, and can lead to damage later on, or at minimum, a thinning of the turf.

Centipedegrass may also experience issues this spring, and just like St. Augustine grass, it may take a lot of time to recover since neither of them have below-ground rhizomes. They both grow above the ground through stolons, or runners. This makes recovery and regrowth of these species more difficult.

Other issues, such as cold and drier-than-normal air, increase the risk of damage, specifically in southern turfgrasses, drying the crowns of the plant out completely. Also, possible damage may occur from standing water. In certain cases, there was rain right before the cold weather hit and all that stagnant water froze in and around the crown of the plants, causing damage or weakening the plant.

When it comes to the more northern states, on the other hand, there is some concern for damage with the Tall Fescue and Bluegrass species; but typically, the damage isn’t near as bad as it is with southern turf. If the temperatures warm up enough to allow the water to thaw between the plant’s cells, then the cells will re-hydrate and if it gets cold again, and a hard frost occurs, Freeze Damage can occur.

Freeze Damage looks a lot like random white streaks or bleached out areas. These discolored areas happen when young, tender new growth freezes after a cold snap. This will usually last for only a short period of time before it recovers and grows out.

So, what can you do to help the grass in the meantime?  Be aware that excess foot and vehicle traffic may worsen the effects of cold damage, so stay off damaged turf until the soil and plants have completely thawed. The healthier the turf, the more stress it can handle, so last year’s applications will help.
