When is it best begin pre emergence application of Tenacity, I plan on 3 applications app 2-3 weeks apart. Is it best to wait for temperature or apply on a specific date. I live on Cape Cod in Eastern Massachusetts
Pre-Emergents typically should be applied in the spring before ground temperatures reach 55 degrees and again in late summer/early fall. For more specific recommendations based on the current climate of your region we would recommend contacting your loacal Master Gardener.
