I'm not an expert on planting grass seed, but trying to germinate grass seeds on my newly cleared acreage has been a complete failure so far. Until now.
When I used the preferred method: mixing with sand and broadcasting, two things happened.
1. Pigeons, ducks and doves: dozens of them assembled for the feast. Fail.
2. Any rain that came, which was vital for germination, washed the seed down the slope, where it germinated. Fail.
Even when raked into added top soil the birds scratched it out. So after wasting bags of grass seed broadcasting, I opted for planting it. I used a buffalo, rye and couch lawn grass seed mix from the local farm store to start the process.
1. Dig a long trench about 5 cm (2 inches) deep- enough to stop the pigeons digging it up, but not too deep that it can't get to the surface.
2. Fill the trench with water - the most important step here - the soil base need to be wet
3. Throw seed into the water -lots of seed. Make sure the seed is floating for a few minutes so it absorbs the water
4. Cover the seed with compost then soil -compost will aid the water absorbtion
5. Water in again.
I dug about 5 or 6 trenches at once and and did this process like an assembly line. I also cut the trenches across the fall of the property so after it germinated: about three days, silt and sand being moved by rainwater banked up against the run of grass.
Obviously to germinate grass seeds you need lots of hosing, sprinkling and some rain is helpful. After a few weeks I threw on some lawn fertiliser to aid its spread. The ducks do come in amd trim it down, but that's ok as they help it spread as well.
