After the selection is made, call the Vegetation Management Section for assistance in determining the planting rate or use charts in the Wildflower Guide. The planting rate (number of seeds to be planted per acre) is based on the following factors:

The effect desired in the area being planted will depend on whether the landscape is meant to be observed at long range (such as highway rights of way) or subject to closer scrutiny (such as walk-through gardens).

The department requires that seed vendors provide the current year PLS for each batch of seed. If the seed purchased was tested more than 12 months ago, it will need to be retested. (The Vegetation Management Section staff will provide assistance, if necessary.)
