When I tour Botanical gardens around the USA, the ones that appeal to me most are those that have greenhouses as part of the gardens.

I’ve been trying to get my husband to build me a greenhouse in our back yard for years, but it seems that this is one project that just gets put on the back burner indefinitely. 

Since I haven’t seen signs that this project will happen any time soon, I thought I would see what other homemade greenhouse ideas were available.

Using recycled materials in projects appeals to me and many of these DIY greenhouses do just that. 

Why have a greenhouse?

One of the many things that I love most about greenhouses is that they are both pretty and practical. Greenhouses are equally at home in a small backyard or in a sprawling English cottage garden.

The purpose of a greenhouse is to protect plants from excess cold or heat and to keep away unwanted pests. A greenhouse makes it possible for us to garden all year round – even in the winter! 

Whether you are starting seeds for your summer vegetable garden, or propagating plants to get new ones for free, a greenhouse will be a huge helper to you.

Normal greenhouse designs are made of hardwood and glass and can be quite expensive. Here is something you might not know, though – You don’t actually need to a lot of money to own a greenhouse yourself. 

DIY greenhouses can be put together quite inexpensively if you make use of recycled common household materials.

Types of Greenhouses

Greenhouses come in many forms. There are large upscale buildings that blend beautifully into the decor of your property and small make-shift designs with plastic tubing and siding that do the job in a more practical way.

You can put together mini greenhouses that act as a terrarium to house indoor plants or use cold frames to grow vegetable greens even in the dead of winter.

Difference between a greenhouse and a cold frame

The main difference between a cold frame and a greenhouse is that a cold frame is normally a small, simple structure that is just a few feet tall, whereas a greenhouse is a large structure that one can walk in.Greenhouse vs cold frame - two homemade greenhouse ideas

Both are designed to keep the elements from plants and prolong the growing season when the weather turns cold.

Because of their size and construction, cold frames are a more cost friendly option.

    I’ve made many greenhouses over the years, and the last several were made with most of the materials “rescued” from the discard piles at the street curb.

      Normally the problem is that monkey grass takes over, rather than it being slow to grow. I can’t diagnose problems in a yard without seeing the yard in person, but it could be the clay soil. Some compost added to the soil might help to make it drain better.
