28 DIY Greenhouses That Are Cheap and Easy to Build
Your plant babies have never been happier than they will be in one of these greenhouses.
Spring is right around the corner, which means the time to start planning your garden and starting your seeds is now. The first day of Spring is officially March 20, but every good gardener knows that essential garden prep begins long before that. The only problem? The weather doesn't exactly cooperate with the calendar.
Late season frosts and snow are a familiar foe to many gardeners around the country and can bring garden prep to a complete stand still, to say the least. At best, many gardeners have to deal with moving plants inside and pressing pause on preparations for the coming season. At worst, precious seedlings can be lost and you may find yourself having to start over completely.
Fortunately for those of us in cooler climates, there is a way to get a head start on your garden without having to worry about the weather: get a greenhouse. Greenhouses allow you to start seeds and by protecting your plants from frost, snow, and cold temperatures. While you might think of a typical greenhouse as a massive structure that only farmers use, there are plenty of smaller greenhouse options for hobby gardeners—including more than one DIY option. These greenhouses are cheap, simple to assemble, and come in a variety of different sizes depending on each gardener's needs and wants. Assess your garden to see what size you'd like and then pick one of these below!
