Research has shown that most people aren't aware that planting beds should be irrigated differently than lawn-- thus they water planting beds with overhead spray and with the same frequency as the lawn. As a result, they're providing exactly the conditions weeds need to flourish. All plants, both weeds and desirable plants need five things to grow: 1. Soil 2. Air 3. Nutrients 4. Sunlight 5. Water You can't do anything about the first three conditions for weeds but if you use our Weed Control Recipe and follow ALL of the steps, you can take substantial control over sunlight and water-- thus reducing weeds in your landscape by 80% or more.
