ProblemsWeeds : Preventing Weeds and Grass
Weeds rob your plants of water, nutrients and light. They can harbor pests and diseases. Before planting, remove weeds either by hand or by spraying an herbicide according to label directions. Another alternative is to lay plastic over the area for a couple of months to kill grass and weeds.
You may apply a pre-emergent herbicide prior to planting, but be sure that it is labeled for the plants you are wishing to grow. Existing beds may be spot sprayed with a nonselective herbicide, but be careful to shield those plants you do not want to kill. Non-selective means that it will kill everything it comes in contact with.
Mulch plants with a 3 inch layer of pinestraw, pulverized bark, or compost. Mulch conserves moisture, keeps weeds down, and makes it easier to pull when necessary.
Porous landscape or open weave fabric works too, allowing air and water to be exchanged.
