Let us talk native grass establishment, sounds like fun, HUH. Really it is not all that bad. The great thing about native grasses and wildflowers is that they are versatile. Good soils, bad soils, wet soils, dry soils, partial shade, full sun, there is a plant or combination of plants that will adapt to areas and thrive.
Native Grass Establishment
If there was one word that summed it up, the one word that a person needed to embrace before planting and establishing native grasses, it would be.........no not miracle, but patience. Native grasses, and especially warm season grasses are slow to germinate and slow to mature. It is their nature, and when we humans try to rush what wants to go at it nice and slow, the process gets frustrating. So here is what we recommend. Remember, we are talking native grasses this time and later will come the wildflowers.
Assess the situation. What is the condition of the area you want to grow native grasses in? Is there existing vegetation? Bare soil? Dead existing vegetation? Existing vegetation that needs to be killed off first? No one area to be seeded is the same, so we have to look at every area differently. Existing vegetation, whether you want it living or not is not a bad thing. Residue, helps to conserve moisture and if the area can be left undisturbed (not tilled) then that will not only help conserve moisture, but minimize weed seeds that are laying dormant in the soil waiting to be disturbed and create competition for young native grass seedlings down the road.
Seeding methods are important. The most important idea to remember is seed-to-soil contact. Getting the seed into the soil will present the best opportunity to germinate. Why? If the seed is laying on top of the soil, nothing surrounds that seed, better encapsulating it to hold moisture, as well as the soil acting as an abrasive (scarification) on the surface of the seed. Scarification allows moisture to enter the seed and help initiate germination. So seed placement in the soil and not merely laying top will greatly increase the percentage of seeds that will germinate. There are mechanical drills that slice past the existing vegetation/residue to place the seed at an optimal depth. Drill seeders are well worth the money to either rent or have custom seeded. Most drill seeders fit on the back of small tractors. Broadcast seeding can be done effectively if followed up raking or dragging over the soil with a chain link fence.
Seeding dates are very important as the difference in a month can be mean dead seedlings. Cool season grasses, much like turfgrasses can be seeded April through May and Mid August through Late September. Warm season grasses, with their limited growing season, needs a little more consideration. Preferably, warm season grasses need to be seeded April through Late June. If done too late in the season, which is considered past July, then the slower establishing warm season grass, tender in juvenile state can fall victim to frost. The seedling needs to develop enough of a root system, so as to survive a frost. Here is the great part, did you know that dormant seeding (seeding into soil that is too cold to germinate) can be done with both cool and warm season grasses. Some seeds lay in dormancy, waiting for some change in it's physiological state to initiate germination (stratification). And a native grasses that is laying within the soil, overwintering until the time is right to germinate in the spring is a very good way to get a head start in the spring. If nature can do it, so can you!
So there you have it, a guide to planting and establishing native grasses, not so hard after all. Just remember the following concerns:
- What to do with the area to be seeded. Vegetation? Bare soil?
- Seeding method. The better the seed is placed in the soil, the better the germination rate. Seed laying on the soil will not germinate.
- Seeding date. Just remember, cool season and warm season and plant accordingly.
Next time, we will talk wildflowers, which can be interesting, but oh so rewarding!
