Why does crabgrass turn red

Understanding how crabgrass works and how to break its cycle can help you get rid of crabgrass and keep it gone. Crabgrass is a warm-season annual that germinates, lives and dies all in the same year.

But crabgrass problems don't end with the growing season. While they live, each crabgrass plant produces up to , seeds. Seeds that don't germinate right away can remain viable and stick around to germinate in future years. Once crabgrass seeds germinate and plants emerge, mowing your lawn short won't stop the seeds.

Effective control requires preventing crabgrass seeds from ever becoming seed-producing plants. With hundreds of thousands of crabgrass seeds potentially waiting in your lawn, preventing their successful germination is essential. Crabgrass preventer products use what are known as "pre-emergent" herbicides, which target germinating seeds before new shoots can emerge from soil.

Pre-emergents work by inhibiting seed germination and root development so that seeds can't become established plants. This premium product then continues preventing these weeds for up to five months, while it feeds your lawn grasses at the same time. While crabgrass preventers target weed seeds, they can inhibit germination and establishment of lawn grass seed, too. Always follow label instructions regarding seeding and your specific preventer product.

As a general rule, wait at least 60 days and at least two mowings before overseeding lawn areas where crabgrass preventer was used. A single crabgrass plant can set up to , seeds in a season. Because crabgrass preventers only work before crabgrass seedlings emerge through the soil, timing applications right is critical to success.

Preventers must be applied before crabgrass seed germinates. I've sprayed some crabgrass in my yard and its dying slowly. I've sprayed it for a second time about 1 week after my initial spraying.

One of the common causes of discoloration this time of year is brown patch fungus which causes patches or rings of tan, yellow or brown grass. These spots tend to spread and are almost always indicate a fungal problem. You may notice spots on the grass blades or that the blades will uniformly lose color.

Whether you want to treat it yourself or hire us, I recommend that you act very quickly to get this under control. I recommend an immediate fungicide application with a minimum of 2 re-treatments to ensure that the disease is under control.

Does your lawn have a brown tinge across the whole yard? For Zoysia and Centipede lawns, the cold weather causes the grass to turn completely dormant and almost look partially dead during the winter.

Do not be afraid, as these lawns will bounce back to lush green lawns in spring with proper feeding and treatment.
