I can day-dream about them all day long … greenhouses and cold frames! They are such effective structures to extend the season, allowing us to grow an abundant garden year round even in the cold winter!
Here are some of the BEST tutorials on how to build amazing DIY greenhouses , simple cold frames and cost-effective hoop houses.
You will discover that you can have a great productive greenhouse or cold frame even when you have little budget and little carpentry skills.
There is a perfect DIY greenhouse for everyone! ( Note: this post has been updated: now we have 42 greenhouses! Just have to add some really great new ones! )
Every one of these greenhouses and cold frames contain lots of inspirations to learn from. You will find ingenious ideas such as passive heating elements of painted jugs, straw bale as building material that needs no tools, using tree branches, old bottles, windows, and even a trampoline! ( Some of the helpful resources are affiliate links. Full disclosure here. )
Before we dive in, I want to share with you two of my FAVORITE books on greenhouse gardening-
The classic is Four Season Harvest: Organic Vegetables from Your Home Garden All Year Long by Elliot Colman. He gardens year round in cold Vermont, and shares simple, inexpensive designs for cold frames, unheated mobile greenhouses, and root cellars in this amazing book.
The new ground breaking ( literally) book The Forest Garden Greenhouse is written by the brilliant permaculture designer Jerome Osentowski who grows bananas and citrus on a rocky hillside in Colorado with winters in -30s.
