Put away your soil! Because you won’t need much of it to start (or propagate) these herbs, vegetables, and plants. These grow in water instead!
#1 Peppermint: While peppermint will eventually need to be moved to soil, you can propagate peppermint in water from leaf cuttings. 17 Apart has a great tutorial for beginner gardeners.
#2 Spearmint: Because it’s closely related to Peppermint (it’s actually a cross between peppermint and aquatic mint) Spearmint is another herb that can be started in water. HomeGuides has more.
