We burn a lot. We burn using what they call prescribed burning (vegetation creates heat), we burn using propane burners of several sizes. Because of mid-Atlantic weather, we will do prescribed burn followed with mechanical burn because of higher humidity but having to get the work done. We burn with horticultural vinegar. We also use shallow tillage. Sometimes we use these in tandem. When to burn? Depends. We see evidence that burning a bit later in Spring stresses out cool fescues more than before it starts to green up. This is where having the mechanical burner is an advantage.
