Are you trying to find the best greenhouses for Arizona?

Like any other region, Arizona has its own batch of troubles you’ll need to overcome to maintain a garden. The right greenhouse can actually help you extend your growing season.

We’ll be showing you what we think are the some of the best greenhouses suited to Arizona’s environment. On top of explaining why we like each one, we’ll explain what to look for on your search for a greenhouse of your own.

Why You Should Have a Greenhouse in Arizona

A lot of people assume you only need a greenhouse in places that get really cold. After all, greenhouses are usually used to keep plants warm.

While that is true, greenhouses also work as a shelter for your garden. Not only will they protect plants from the cold, but they can safeguard your plants from pests and harsh conditions, including hot temperatures.

Essentially, a well-made greenhouse will help form an environment that’s as close to perfect as possible, regardless of where it’s standing.

Although Arizona is generally hot and sunny, it can easily get too warm for many kinds of plants. And during the monsoon season, you may struggle to protect an outdoor garden from pests.

A greenhouse can help you deal with those gardening issues.

What to Consider When Buying a Greenhouse for Arizona

Temperature Control

Needless to say, Arizona is a hot environment. Your biggest enemy is going to be the heat. Greenhouses naturally are designed to hold warmth inside, but in an already hot setting, it means that it can also get too warm inside.

There are a few things you’ll need to think about with your greenhouse. To start with, examine any greenhouse’s ventilation. Many have vents that will even open automatically when temperatures rise, releasing hot, stale air with no effort on your part.

Insulation will be another helpful quality. A well-insulated greenhouse is one whose internal temperature is protected from the outside, whether it’s hot or cool.

Some greenhouses have frames designed to increase insulation, while others have seals around the windows and doors. If they don’t have such seals, you might want to seal up any cracks yourself.



The harsh sunlight and occasional flash floods make Arizona a tough setting for any building, including a greenhouse. Your greenhouse will need to be extra-tough in order to survive for years.

If you’re using a tent-like greenhouse, you’ll want to make sure it’s staked to something secure. These types of greenhouses will usually come with stakes or anchors that you can use to achieve this.

The material used to make the greenhouse will also be crucial in this regard. Polycarbonate panels are common with greenhouses, because they’re remarkably strong and resistant to all kinds of weather conditions.

Protection from Pests

Caterpillars and other pests can be a major issue in Arizona. These pests are also detrimental to your garden, whether it’s indoors or outdoors. You’ll need to make sure your greenhouse is protected against them.

Screens over vents will help with this a lot. Some greenhouses are built with these screens over windows to prevent any insects from getting in.

Insulation can also help. Just as insulation prevents air from escaping or getting in, it can also stop some pests from sneaking in, too.
