Growing Annual Grasses
Choose a wide, shallow pot, such as a bulb pot, to sow the seeds in. Fill it up to about an inch from the top with potting soil, then sprinkle the grass seeds over the top. Aim to space the seeds about 1/4 inch apart. Sprinkle about 1/2 inch of potting mix over the seeds and press to get good contact between the soil and seeds. Water well and place where it will get at least a half-day of sun. Keep evenly moist and seeds should germinate within a week. Wait until the grass is a couple inches high before giving it to your cats to nibble. Water regularly and feed with a fish emulsion solution every couple of weeks. If you plant a container every 4 to 6 weeks, you'll have a steady crop of grass to keep your cats happy.
Growing Catmint and CatnipWhile cat grasses are fast-growing and tasty (if you're a cat), they are annuals, which means you need to re-sow seeds in order to keep them continuously growing. Catmint (Nepeta mussinii) and catnip (Nepeta cataria) are herbaceous perennials, meaning that they will die back to the roots in the winter, but re-sprout from the same root system in the spring. They also both contain the organic compound called nepetalactone, which is known to attract felines. In other words, catmint and catnip are recreational drugs for cats.
ResourcesThere are several companies that offer seed mixes for cat grasses as well as catmint or catnip seeds. My favorites include Renee's Garden Seeds, Burpee, Peaceful Valley Farm & Garden Supply, and Botanical Interests. You can also use pre-seeded disks, available from Botanical Interests, which are more expensive, but easy to use and result in more even sprouting.
