How does it Work?
Corn Gluten works as a natural seed inhibitor. It prevents the roots from growing as the seed germinates. You will see the weed emerge, but then die off, as it cannot form a root system to sustain its growth.
- TIP: Once the plant tries to grow, and the corn gluten stops it from growing roots, it is best to not water your lawn for a day or two.
It does not affect the healthy root systems of pre-existing plants or transplants with developed root systems. This means it does not kill weeds that have already grown. It also means that it can be safely used in the garden to control weed seeds from growing.
One application lasts for 3-6 weeks, because of this you should apply corn gluten 3 times a year to be effective against the most types of weeds. Corn gluten needs to be ‘activated’. It will not start working until it becomes wet, it is best to apply before a light rain-fall, or water in lightly with a hose-end sprayer.
- Early Spring: This is usually done in mid/late April depending on the season. This application works best for controlling crabgrass. If you know what the forsythia bush is, you want to apply before it finishes blooming. DO NOT APPLY WITH GRASS SEED, AS IT WILL PREVENT IT FROM GROWING.
- Mid-May: This is best time to apply to control dandelion seeds that have blown in.
- July/August: If you have a problem with dandelions in neighbors lawns, you may want to apply corn gluten again. Dandelions will send out seeds again this time of year.
