Put newspaper over the dirt 3-4 pages thick & then cover it with mulch. The newspaper will prevent any grass & weed seeds from germinating, but unlike fabric, it will decompose after about 18 months. By that time, any grass & weed seeds that had been present in the soil will be dead. It’s green, it’s cheaper than fabric, & when you decide to remove or redesign the bed later on, you will not have the headache you would with fabric.
Homemade Weed Killer 1 gallon of white vinegar, 1/2 cup salt, Liquid dish soap (any brand), Empty spray bottle. Put salt in the empty spray bottle and fill it the rest of the way up with white vinegar. Add a squirt of liquid dish soap. This solution works best if you use it on a hot day. Spray it on the weeds in the morning, and as it heats up it will do its work. by ladylynne213
