5 DIY Greenhouse Ideas for Growing Your Own Food Easily

Even though the cold winter months are quickly approaching, you mustn’t think for a second that it’s too early to start planning for your spring harvest. Gardening might not be the first thing to come to mind when we think of winter, but these DIY greenhouse ideas will soon change your perspective!

The middle of the winter, when you probably entertain fewer outdoor activities, might just be the ideal time to plan your spring garden. Getting ahead of the game is not just exciting; it also ensures that spring will find you ready to sow your garden.

Learning the Theory

Before we get to action, it’s only fair that you catch up on a bit of useful reading about gardening. This is especially useful for those who have never had a DIY greenhouse before. There are two classics that you might want to read before you start planting.

One of them is “Four Season Harvest: Organic Vegetables from Your Home Garden All Year Long” by Elliot Colman. In this book, Colman shares inexpensive solutions for root cellars, cold frames, and unheated mobile greenhouses. His example of gardening year round in a cold environment is definitely inspiring.

“The Forest Garden Greenhouse” is the new groundbreaking book written by Jerome Osentowski. He is a brilliant permaculture designer who took on the challenge of growing bananas and citrus in -30 winters.

Getting Started

Do you live in an area with short growing seasons? Then it’s particularly critical to start planning your garden early. If you want to start a garden from seeds instead of seedlings, make sure you order your seeds ahead of time. For best results, choose heirloom or organic seeds. They will ensure you can save seeds for next year’s sowing.

Saving seeds from hybrid plants is not a good idea, especially for a beginner gardener. They will either be sterile or provide unexpected results. If you feel out of your element when it comes to choosing the right seeds, check out this list of free gardening catalogs.

Now you have a plan and the seeds in your hand. Next step is starting your seed garden indoors. Getting a jump start during winter will allow you to extend your growing season. Upcycled containers are a great green way to plant your seeds indoors. If you have kids, make this DIY project a family hobby, using it to teach them about leading a sustainable lifestyle.

DIY Greenhouse 101

You really do not need a really good budget or an expensive greenhouse to feed your gardening desire. Instead, starting a DIY greenhouse project might be perfect for you. While there are plenty of beautiful pre-fab greenhouses on the market, you can build your very own greenhouse for a fraction of the cost of buying one.

While some might consider it a daunting task, building a greenhouse from scratch it can be quite fun if you know where to start. Below you will find 5 DIY greenhouse ideas that are not just affordable, but also vary in skill levels for all of our readers out there.

What You Need:

  • Stud walls
  • Corrugated plastic greenhouse panels
  • Tin panels
  • Tin screws
  • L flashing (optional for the corners)
