Fall Lawn Seeding
Crab Grass, even when there were effective chemicals available, was one of those weeds that slipped through the cracks. Pre-emergents would give some control before the crab grass germinated but there was nothing to treat it after it germinated.
Corn Meal Gluten is effective if applied at just the right time. The principle is that it creates a barrier that the weeds do not grow through. It lasts for about thirty days from time of application. The problem is in timing the weather perfectly and being diligent with your application.
About Crab Grass
- It is an annual. It will not grow back next year.
- It is a prolific seed producer. If you let it turn to seed those seeds will be there for the next season just waiting. (plus more)
- It is brought to your yard mostly by sand used for winter maintenance and brought in for landscaping (screening, top dirt).
- I can tell if some one has “re-pointed” or repaired their interlock drive by the pattern of crab grass growth along the boarders of these areas.
- It is transferred from such areas as the boulevards or lawn adjacent to walks and drives to the middle of your yard by mowing practices and foot traffic.
- It grows rapidly and will destroy the lawn quickly.
- It may not grow back next season but if left unchecked it will be very stocky and will make repairing the lawn more difficult. It will be harder to trim down. There will be seeds and a worse outbreak (depending on the weather.
Crab Grass Control
If the Crab Grass has already emerged there are some easy ways to control how much damage it creates.
- Cut it back right to the ground so there is no green showing
- wear safety equipment as there will be flying rocks and grit.
- This WILL wreck the other grasses where this work is done.
- It will look messy
- It is far easier to keep up when the new growth is young.
- DO NOT LET IT TURN TO SEED
- Where there are single plants (middle of lawn) you can cut just below the surface with a sharp knife or pull
- yes you can also hand pull them all
- Wait until second or third week of August or the beginning of September and reseed lawn (when the weather will not trigger the Crab Grass growth.)
- please read blog on grass seed
- When having landscape construction work done around your home be neat with materials
- When mowing your lawn always cut the crab grass area last if you can and immediately clean your lawn mower after use. (or before you transfer to an unaffected lawn)
- If you use Round Up or an equivalent product as a homeowner you will still damage the lawn around the outbreak and, depending on when it is done, the crab grass may still turn to seed.
- If you use this product you should still consider trimming and clean up
- consider that Round Up will kill the perennial grasses in the infected area whereas the technique above will not. Round Up is not advised!!
