Dandelion (weed)

We will be blanket spraying select yards for dandelions. Please wait for 6 to 8 hrs before watering. Dandelion season lasts for 2 to 3 weeks. We put pre-emergent down on the first application. But that will not prevent all the dandelions from germination. That is why will be blanket spraying select yards. It is normal to get about 40 dandelions in your yard each year. There is a number of reasons you might have dandelions, here are a few: your home is near empty lots or fields. Your neighbors might not treat their yard for dandelions. Dandelions will not affect your lawn in the long run.
