Did you know that cornmeal is birth control for seeds? Sprinkle it on your garden and it will keep weed seeds from germinating and growing into plants. Of course, cornmeal will keep any seed from germinating, so don’t try this on your vegetable garden until your plants are established and you’ve ﬁnished planting seeds.
The newspaper will prevent any grass and weed seeds from germinating, but unlike fabric, it will decompose after about 18 months. By that time, any grass and weed seeds that were present in the soil on planting will be dead. It’s green, it’s cheaper than fabric, and when you decide to remove or redesign the bed later on, you will not have the headache you would with fabric.
