The importance of site-preparation for pollinator gardens cannot be overstated. To prepare a site, eliminate existing undesirable vegetation, eradicate weeds, remove plant debris, and ensure a clean surface for seed to soil contact or transplants. Tilling should be avoided as it kills ground nesting insects and damages soil structure. Two effective site preparation methods are smothering and solarizing, which are chemical-free and can be up to 90% effective at eradicating weeds.
