If you’re antsy to start your plants early in the spring, but frosts keep falling into April and May, then it makes sense to get a greenhouse. The problem is that even cheapy greenhouses tend to be costly, and the nice ones run thousands of dollars. If you’re growing your own vegetables to save money, you may not be willing to spend that kind of money right now.
Cold frames are alternative. They’re kind of like plant-sized mini greenhouses.
While you won’t be able to grow trees or big bushes in something like this, a cold frame can be perfect for starting your plants early so they can get a head start when they’re transferred into the garden later.
While it’s certainly possible to make a cold frame from scratch (I’ve heard of people using old storm windows and scrap wood), you can make things easy by picking up a spacious one like this double cold frame from Planet Natural.
It gives you 12 sq. ft. of growing space and comes with four hinged vents and four stakes for anchoring to the ground. It’s 1′ (front) to 1.4′ (middle) high, so it should offer plenty of room for starting plants.
