I wanted to test methods of applying pre-germinated grass seed without the extra steps of drying the seed. I soaked an ounce of perennial rye in 2 gals of water, indoors at 65 degrees, for 22 hours. I tried to apply the "seed slurry" with a small hand sprayer. I removed the nozzle from the wand. I found that I had to also remove the internal "pick-up" filter. The seed settled out quickly--agitation was needed. I tried removing the internal pick up tube, and then holding the sprayer upside down. But still almost no seed appeared in the stream coming from the wand. I suspect that the hand valve was too small internally. Perhaps a quarter-inch ball valve would work. I found that the seed slurry could be siphoned from the large container to the ground or to a smaller container with half-inch vinyl tubing or hose. I prepared two 3 by 3 foot plots, and applied the seed slurry as a liquid to the soil using a watering can with a half-inch opening,(left in the photo). Frequent agitation was needed as the seed tended to settle out. The seed sometimes appeared in a narrow band about an inch wide. I planted an ounce of the dry ordinary non-pre-germinated perennial rye adjacent to the wet-applied seed.(Right in the photo). The seed was not raked-in. Temperature was 52 and cool weather was expected. As an afterthought, I added some seed slurry to a 32 ounce water bottle and applied it by hand on an extra plot. I could shake the bottle and use my fingers to regulate the flow. I planted a small sample indoors in paper cups with drainage. One was planted wet, and one planted dry (non-pregerminated).
