It covers as much as you want to use, I grow mine in pots indoors & use a small 4” container like they sell in pet stores. You can grow outside weather permitting in pots, it’s not like regular grass seed, since it dies off after a couple of weeks.
No - it does not. It is very easy to pot in regular potting soil. I use a sturdy square pot which can’t topple over that I leave on the floor for my cat so she can munch when ever she wants - though she prefers to be hand fed indeed blades. My cat loves this grass and eats several blades a couple of times a day. This large bag of seeds lasts a VERY long time.
Yes, after your cat eats the grass
Greetings Danielle - the seeds do not need to be soaked before planting them. Fill a planter pot with potting soil to nearly full - then soak the soil in the planter so that it is completely saturated with water. Sprinkle the surface with seeds and add a very thin layer of potting soil over the seeds - about 1/4 inch of soil over the seeds. Gently saturate the top layer of soil without disturbing the subsurface seeds. Keep the soil saturated with moisture for about 5 or 6 days. You will see the grass push up through the soil pretty quickly and you can start using the grass when it is about 6 inches high. I let the grass grow fairly high. Each leaf with add secondary leaves and then third and forth leaf on each seed the taller it grows. I plant a handful of seeds in a 6" x 6" x 6" square pot. I use a square pot for stability in case my cat Dori pulls at a chunk of grass when she munches on it. My cat prefers to be hand feed a leaf at a time. It makes it possible for her to get the full length of the grass blade. My cat is crazy about eating the grass through out the day. She plays at getting my attention and when I follow her she runs straight for pot of grass and purrs very contentedly when I pluck the blades and feed them to her. She'll eat a dozen or more grass blades when I hand feed them to her.
