We grow catnip in the corner of the front yard. It’s a lovely bushy silvery green plant that smells a bit weedy when touched. Catnip is an easy plant to grow and takes a far amount of shade. We keep catnip both to use in tea for us and to entertain our cats in the winter.
If you want to grow catnip you can easily find a started plant at your local nursery.
You could save some money and start your catnip from seed if you would like more than one plant. Be warned that catnip is in the mint family and can be a bit invasive. To get around this, you may either plant it in a pot or in a space that you don’t mind it taking over. My plan is to put my new little plants in the corner of the yard under a bush that could use some brightening up.
When you are ready to preserve your catnip simply cut it, bind it and hang it. Never cut more than 2/3 of any plant in the mint family to keep it healthy. When you hang herbs to dry it is best to find an airy, dry place that does not get direct sun. I don’t have a place that is all of those things so mine go up in the window.
