If you are having rains, let the rains keep it moist, otherwise you will need to make sure it receives enough moisture. Your wildflower seed will not survive among grasses or other weeds,even if they are small at the time of planting. Wildflowers take between 14-21 days to germinate. In that time, small grass will have grown considerably. For best results, remove all grass and weeds prior to planting your seed.
All plants fall into one of two categories.
They are either narrow leaf or broad leaf in composition. It has been our experience that grasses cause the most difficulty in planting wildflowers. They are fast growing and often out-compete the lesser aggressive wildflowers for space and sunlight. When correctly applied it will eliminate the narrow leaf plants and not harm the broad leaf plants. We use it and we can therefore recommend it to you.
