Best Greenhouses for Maryland

Gardman 4-Tier Mini Greenhouse

A sturdy greenhouse doesn’t have to be big and expensive. The Gardman 4-Tier Mini Greenhouse is proof of that statement. Unlike the other options on this list, it’s petite, making it ideal for cramped living situations.

Its tower-like structure accommodates a few small planters or pots. Over the top, you can slide on a polyethylene cover that holds in the heat when it’s cool outside.

The smaller size means it won’t take as long to assemble as other choices. Whereas a huge greenhouse could take half a day or more to set up, this mini-greenhouse can be assembled rapidly. The tough steel frame can actually be put together in as little as a few minutes.

Pros:

• Affordable.
• Its compact size makes it easy to squeeze this greenhouse in anywhere.
• Because it’s lightweight, it can be transported whenever you need to move it.
• The durable polyethylene cover holds in heat well.

Cons:

• Although it includes stakes for stability, you may want to secure it better to wherever you put it.
• It does not have a vent on top.

Mt. Hood Greenhouse

One of the biggest reasons we chose to include the popular Mt. Hood Greenhouse is its incredible staying power. This is truly a greenhouse that will last through all adverse weather conditions, whether it’s wind, rain, or snow.

Its unbelievable durability is mostly due to its frame. The frame is crafted out of all-natural redwood and allows the greenhouse to withstand hurricane-strength winds of 100 mph.

We also love its organic plastic base. Aside from being made from recycled plastic, it can resist pests and fungus. In a humid setting like a Maryland summer, this can be critical.

Pros:

• The roof vent and back wall vent naturally create a cross-breeze when both are open.
• It was made using natural and recycled materials.
• Capable of withstanding winds up to 100 mph.
• Slanted roof panels are excellent for getting some late evening sun rays, even in the winter.
• You don’t need a lot of tools to assemble it.

Cons:

• The assembly instructions can be a bit confusing.

Little Cottage Company Greenhouse

This tower-shaped greenhouse probably stands out to you when it compares it with a few others. It had the same effect on us, partly why we chose it.

However, we also picked it because it’s tough as nails. With a wind rating of 90 mph, you can expect this greenhouse to keep going even after years and years of intense storms.

As you can see, there are tons of windows all over its exterior. These can each be opened to vent the inside when it gets a little too toasty. You can even open windows on the opposite sides to make a natural cross-breeze for efficient air circulation.

As a bonus, the windows have screens on them. That means bugs can’t get in, even when you have a bunch of windows open.

Pros:

• There’s a wrap-around shelf built around the edge of the greenhouse inside.
• Each window can be opened for ventilation and air circulation.
• Because of the screens on the windows, you can open them for air without letting insects in.
• Able to withstand winds up to 90 mph.
• There are built-in rods to hold hanging baskets.

Cons:

• You will have to purchase paint separately if you want it to be a certain color.

A gorgeous wooden shelf is attached to three of the walls on the inside. Above the shelf, you’ll find rods used to suspend hanging planters.

Riga Greenhouse

Looking for a roomy greenhouse with the persistence to stand in your yard for years to come? The Riga Greenhouse is a winner in that regard.

There are two main factors that lead to its toughness: its shape and its frame. The pointed shape makes it difficult for snow and other debris to pile on top. It also doesn’t catch in the wind.

The aluminum frame lends it stability. It won’t be blown over, even in winds up to 80 mph.

But perhaps one of the most convenient features it has are the vents on top. They’re entirely automatic. As the temperatures increase, they’ll slide open on their own, venting the inside without you having to leave the comfort of your home.

Pros:

• It has a sturdy aluminum frame
• Snow won’t pile up on top.
• The automatic vents will open on their own when the heat builds.
• There is shelving built right in on the inside.
• The materials are resistant to UV rays, rot, and mildew.
• A roomy interior holds a large garden.

Cons:

• None reported yet.

What to Consider When Buying a Greenhouse for Maryland

Insulation

Maryland has very distinct changes in-between seasons. For that reason, a well-insulated greenhouse is an absolute requirement.

You can look into the thickness of the panels. The thicker they are, the harder it is for external air to enter and tamper with the temperature you’re maintaining inside. As a bonus, they’re also naturally more durable.

Seals are another important consideration. Some greenhouses have seals around their windows and doors. If your greenhouses do not have this, consider sealing up any cracks you can find with bubble wrap or tape.

Sunlight Diffusion

On cloudy winter days, sunlight is in short supply. Even when the skies are clear, the sun usually isn’t high enough in the sky for a very long time.

That means your greenhouse needs to take in sunlight as efficiently as possible. Generally, this comes down to the material of the panels.

Polycarbonate is perfect for diffusing sunlight. It’s also long-lasting and resistant to all kinds of weather conditions.

You’ll find some greenhouses that use glass panels. These are excellent for letting in sunlight but at the risk of being fragile if they’re not tempered or shatter-proof.

Durability

You wouldn’t want a greenhouse that broken, blew away, or decayed after you set it up. That would be disappointing, to say the least.

But how do you know a potential greenhouse is going to last you for a long time?

Like with many other things, that will come down to what it’s made from. You’ll want to focus on two aspects: the frame and the panels.

As we mentioned before, polycarbonate is a good and hardy material for greenhouse panels. It can endure humidity, wind, and impacts.

Frames can be made out of a wide variety of materials. Many are either metal or wood.

Metal frames are fantastic for their ability to resist mildew and fungus, but treated wood can do the same thing.

Ventilation/Air Circulation

Summers in Maryland can get pretty hot and humid. Temperatures often peak in July, getting as high as 100 degrees.

In these kinds of conditions, it would be an understatement to say efficient cooling is necessary. The best way to protect your plants from harsh heat is ventilation.

For that reason, most greenhouses have vents located on the roof. When open, heat can rise out of them.

But additional windows are a bonus. If you throw open a bunch of windows, breezes will drift in, circulating the stale air within the greenhouse. This can help prevent fungus and mildew from forming.

Assembly Difficulty Level

Like with any other building, greenhouses can take time to assemble. However, this doesn’t mean that the assembly must be a long and painful ordeal.

Many greenhouses implement features that make them simpler to set up. For instance, panels might slide into place, or the frame could snap together.

If you’re not particularly handy, this could make or break your decision on a particular greenhouse.

Wrap Up

From the greenhouses on this list, we think the Riga Greenhouse would flourish the best in a state like Maryland. That’s because of its stunning durability resulting from its polycarbonate panels.

Its shape will also come in handy since snow won’t build up on top and collapse the structure. Furthermore, it won’t blow over in the wind whenever there’s a storm.

Even during the summer, you can rely on this greenhouse. Its vents will pop open by themselves, releasing pent-up stale air.
