Cat Grasses and Other Kitty Treats: You Can Grow That!

Guest Post by Claire Splan Cats (and some dogs) love to nibble at grass, but you may not want to encourage them to chew on the lawn, particularly if the lawn's been treated with non-organic amendments or pesticides. Planting a pot of grasses especially for your pets will encourage them to leave other plants alone (particularly housecats that sometimes nibble out of boredom). You can sow seeds of just about any annual cereal grass but many seed companies sell packets of grass mixes especially for cats. These combinations of rye, oats, barley, and wheat are very appealing to cats, especially when you fertilize them with a shot of fish emulsion. 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 Catnip While 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. Linus, the undergardener, looking for catnip Catmint and catnip need full sun. Sow seeds in the spring or plant container-grown plants in the spring or fall. They will  grow into mounded plants between 12 and 18 inches high. Catmint in particular makes a nice groundcover. Both plants will develop flower spikes (catmint flowers are lavender and catnip can be white/pink/lavender). When the flowers fade, just cut them back and the plant will be rebloom. Although they tend to be hardy plants that will grow in almost any soil, they do best when fed every couple weeks with a weak organic fertilizer. With regular feeding they'll be better able to withstand the constant nibbling that they will have to endure. Resources There 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.
