Plants are often expensive in comparison to seeds. So logically, you'd want to buy cheaper seeds, start them yourself, and then watch in wonder as you fill your back yard with plants for a fraction of the cost of pre-started plants. If only it were that easy.
Growing plants from seeds isn't always as simple as putting seeds in potting soil and watching your new garden spring to life. Rather it's a bit like taking on a new pet that requires lots of time and attention. And those seeds necessitate lighting supplies, soil, plant food, and a bevy of other products that can actually cost you more money than plants that are already partially grown [source: NewsMiner].
And that's just for one type of plant. Other species often require different care as they begin to extend their delicate tendrils skyward. So if you choose to invest in your own plant-growing system, understand that this process can save you money in the long run, but only if you're committed to the work.
If you do plunge into seed planting, be sure to comparison shop online. Online retailers frequently sell seeds for far less than retail stores, and they have a larger selection, too.
