Crabgrass Weed Killer
The best weapon in your quest to reduce crabgrass is pre-emergence herbicide (also called crabgrass preventer). Apply it from the spring before the crabgrass seeds sprout. The granular herbicide works by creating a chemical barrier at the surface on the soil. As the seeds germinate, they take from the herbicide and die.
If you have a particularly bad crabgrass problem, a person application per season may not be enough. Chances are the crabgrass will germinate and spring up later from the summertime.
Pre-emergence herbicides have a lifespan of about 50 days after application (check the label; product lifespans vary). Once the chemical barrier breaks down, dormant crabgrass seeds, which can remain viable for years, may germinate into seedlings. Even if you successfully rid your property of crabgrass, if your yard butts up against property that has a thriving crabgrass crop, you may bet thousands of seeds will blow onto your garden just when your herbicide is calling it quits.
You don't will will need to reapply herbicide to your whole yard. Concentrate your re-application efforts on areas where crabgrass thrives, like the edges of driveways and walking paths. These spots tend to absorb more heat, warming the soil and making for prime crabgrass locations.
Step 1: Wait For Your Second Spring Mowing
. Let backyard growth determine the best time for applying pre-emergence herbicide for getting rid of crabgrass. Apply it after your second regular mowing from the spring.
Step 2: Apply Pre-Emergence Herbicide
. Apply crabgrass pre-emergence granules which has a spreader, especially around driveways and walks and also alongside the neighbor's crabgrass-infested yard.
Step 3: Use Fertilizer with Crabgrass Preventer Added To It
. Use a fertilizer with crabgrass preventer added to it to save time. These combination items are readily available from the spring and cost about $20 for a 5,000-sq.-ft. bag at yard centers.
. Apply the crabgrass preventer/fertilizer combo just before it rains to work the fertilizer and the herbicide into the soil. The fertilizer will help thicken the turf. Thicker turf helps to squeeze out crabgrass plants missed by the herbicide.
. Be sure to apply the product at the right time, between the second and third mowings on the year, when the soil reaches about 52 degrees F. Apply too early and micro-organisms and natural processes while in the soil break down the herbicide. By the time it's needed, much in the product has lost its potency. Apply too late and you've missed the early stage of germination when the herbicide works.
Step 4:Check the Key Ingredients in Crabgrass Preventers
. Look carefully at the ingredients panel for dithiopyr, prodiamine or pendimethalin to determine tips on how you can destroy crabgrass. These active ingredients, which are sold under various brand names such as Dimension, Barricade and Scotts Halts, can get rid of crabgrass in most areas with the country and in many kinds of turf.
. Ask your local extension service which chemicals are best crabgrass preventers for your area and turf species.
. Don't seed if you treat your garden using a pre-emergent. Herbicides that remove crabgrass will also kill desirable grasses such as bluegrass, ryegrass and fescue.
. Control crabgrass during the spring and do your seeding in late summer season or early fall, making sure to keep these two chores at least eight weeks apart. There are a couple of pre-emergent herbicides, such as Tupersan, that are compatible with newly established seed, but they're expensive and can be hard to locate.
Step 5: Recognize and Remove Crabgrass Early
. Pull out crabgrass as soon as you spot it. Young plants leave only a small hole in your turf, which desirable grass types will quickly fill.
. Look for light green grass blades thickening up your Kentucky Blue once your lawn's been growing for a couple months. Before you think your back garden is possessing an exceptional season, think again: It's likely to be young crabgrass.
. Carefully pull out the young crabgrass shoots. Pulling at this early stage is actually a surprisingly effective way to obtain rid of crabgrass. Young crabgrass plants excellent for pulling have two to four sets of leaves but no splayed seed heads. But if the weed has pushed up three or four rows of leaves, inspect it carefully before you snatch it.
Step 6: Look For Immature Crabgrass Seed Heads
. Inspect your yard carefully for slender, green seed heads that are still closed and folded up against the leaves on the plant.
. Carefully pull these out, too. Immature crabgrass plants have tight, green seed heads. They're more difficult to remove, but it's still OK to pull them.
Step 7: Mature Crabgrass Seed Heads
. Keep your eyes peeled for seed heads that spread out like a fork, and leave them alone. Fully mature crabgrass has splayed seed heads. Otherwise, you'll scatter scads of seeds over that nice big hole you've just created by removing the mature weed. You might as well be trying to cultivate new crabgrass! Pulling will leave a big hole inside the backyard garden and spread up to 5,000 seeds per plant.
. Wait for the plant to die while from the fall. Then hit the area next spring with pre-emergence granules to keep the seeds from sprouting. With good backyard care practices, you'll soon crowd out those fallen crabgrass seeds.
Step 8: Spray Stubborn Patches of Crabgrass
. Spray post-emergence herbicide directly on crabgrass after it has sprouted. Pulling is equally effective, but if the roots are deeply embedded in your garden, it may be tricky to pull them out without pulling grass chunks, too. It's not worth spraying a post-emergence product on crabgrass that has gone to seed. It takes about two weeks for the herbicide to work, which is about how long it takes the plant to finish its seeding process. If it has gone to seed, you're better off waiting for next spring and applying a pre-emergence product then.
. Post-emergence herbicides are most effective when the soil is moist and the plants are dry. Read the post-emergent crabgrass killer label for specific instructions. Typically you apply it with a hand pump sprayer. It's best to apply it on a hot day when there's low wind. If temperatures are too low, the product may be ineffective. Unless the crabgrass is young, you'll probably have to reapply post-emergent crabgrass killer several days later (according to the label) to get rid of the plant.
. After post-emergence application(s), keep an eye on the treated area. In extremely dry conditions, water two days after the application to aid absorption. If your grass near the treated area is turning brown, you probably were a little heavy-handed. Soak the damaged area with water to dilute the chemical and avoid further damage. Also, be on the lookout for new crabgrass sprouts. These will require another herbicide treatment, or if there aren't too many, simply pull them. Be sure to seed these areas from the fall.
. Crabgrass while in the fall. Don't waste your money on a post-emergence herbicide from the fall as a route on ways to destroy crabgrass, when the temperatures are falling. The herbicide won't be effective and the plant will soon die anyway.
