You should also be aware that native and warm season seeds are hairy, fluffy and clingy! They will not plant thru a regular drill or planter. There are only 2 ways to plant these seed. Either you have access to a ""NATIVE GRASSES DRILL" or you thoroughly blend this seed with pelletized lime (I suggest adding a little of each at a time while someone mixes with a shovel) and spread out of a cyclone spreader. The seed are so light and knit together readily they must either be planted with a specially designed drill or mixed into a medium that will crush the hairs, separate the seed and carry them some distance out of the spreader.
Also know these seed need seed to soil contact but should not be planted more than 1/2 inch deep. You can spread on unprepared soil before a rain or snow and nature will put your seed down.
Do not prepare the soil if you are concerned about erosion, these plants establish slowly!
I advise not to fertilize at planting! These grasses will grow in poor soil.
Fertilizing before establishment will only improve plants maybe you don't want to a point that they prevent desired plants from establishing.
Best to burn and plant or mow and plant or spread and roll.
If you plant in fall or winter, you might mow cool season plants in the spring but not after warm weather when natives begin to show up.
I add black eyed Susan's, they are pleasing, attract pollinators and will bloom first summer / fall indicating your skill at seed distribution and proving that you planted something cause you won't see the warm season grasses the first year and that causes some to kill it and plant something else before it gets started.
