How To Anchor A Small Greenhouse (Easy Fix)

If you have a greenhouse, then you know how sturdy and secure it is. However, if you try to anchor your greenhouse using ropes that are not sturdy enough, then the structure will be unstable and could fall over in strong winds. 

There are many different ways to anchor your greenhouse, but here are some of the most common methods:

Building a strong anchor system is crucial for a small greenhouse.
The choice of anchoring method depends on the specific greenhouse and location.
Anchoring a greenhouse to the ground provides stability and protection against adverse weather conditions.
Regular inspection and maintenance of the anchoring system are necessary for long-term stability.
Properly anchoring a small greenhouse ensures the safety of plants and equipment.


If you have a small greenhouse, the rope is a great option for anchoring it. The rope can be tied to the ground or trees, and it’s flexible enough to handle some movement in the wind. 

It can also be tied to stakes in the ground or holes drilled into cement blocks if you’re looking for something more permanent.

  • Knots used:
  • Hitch knot (also called “becket hitch”)
  • Round turn & two half hitches

When it comes to anchoring a small greenhouse, it’s important to choose the right methods for different types of structures. Our detailed guide on anchoring a plastic greenhouse provides step-by-step instructions and expert advice to ensure your greenhouse stays secure in any weather conditions.


A hook is an anchor that attaches to the greenhouse and then attaches to the ground. Hooks can be used on any surface, including grass or dirt. 

They are easy to install and remove, making them ideal for those who need to move their greenhouses around frequently.

Hooks are most commonly used with other types of anchors like pins or stakes, but they can also be used by themselves if needed (although this is not recommended).


Chains are one of the most versatile and durable anchor options for small greenhouses. They can be used to anchor your greenhouse in all types of soil, from rocky ground to loose sand.

Chains provide a reliable hold that won’t shift or move over time, so they’re great if you don’t want to worry about un-anchoring your greenhouse down the road. If you choose this option, make sure that your chain is heavy-duty enough for the weight of your greenhouse and wind speed where it’s located.

Are you wondering how to securely anchor your greenhouse to the ground? Our comprehensive article on anchoring a greenhouse to the ground offers valuable insights, practical tips, and recommended techniques to keep your greenhouse stable and protected against strong winds or other external factors.

Cable Ties

You’ll want to use cable ties for anchoring your greenhouse. Cable ties are reusable, easy to use, and available in a range of sizes. They can be used for numerous purposes, including:

  • Securing cables and wires
  • Storing plants that need training
  • Securing tree branches

Metal Ties

You can purchase metal ties from a hardware store or online. The ties are made of steel, stainless steel or aluminum and come in different shapes and sizes. 

They’re also available in several lengths, so you might need to buy more than one length to anchor your greenhouse properly.

Cable Rings

Cable rings are a great choice for small greenhouses. They are easy to install, strong and secure, and they can be removed if you need to move the greenhouse or if you decide to take it down. 

Cable rings also don’t require any tools, so it won’t take long before you have your greenhouse anchored in place.

Cable rings are not expensive either! These anchors will help keep your greenhouse stable even in windy conditions.

Screw-in Ground Anchors

The best way to anchor a small greenhouse is with screw-in ground anchors. These are available in diameters ranging from 1/2 inch to 2 1/2 inches, and they’re relatively inexpensive. 

You’ll need one anchor per 4 feet of greenhouse, so if your structure is 10 feet by 10 feet, you’ll need two anchors total.

Screw the anchor into the ground as deep as possible (at least 6 inches), then attach it to your greenhouse using ropes or chains through eyelets that are built into each side of the frame. 

If you don’t have enough room for a rope or chain attachment on one side of your structure, use a cable instead just make sure it’s thick enough not to break under pressure (3/8″ diameter works well).

Concrete Bases

If you’re looking for a heavy-duty anchor, then concrete is your best bet. Concrete can support the weight of large greenhouses, but it’s not recommended for small greenhouses because concrete bases are heavy and expensive to install. 

For example, if you have a greenhouse that weighs 1000 lbs., your concrete base must be able to support at least 1000 lbs. 

You’ll also need to factor in the cost of hiring professional help or renting equipment in order to dig out the hole and pour in the concrete.

However, if you’re building a greenhouse that will house plants and animals that are larger than average (such as horses or cows), then this type of base might be suitable for your needs. 

And even if all your plants inside are fairly small compared with what’s outside (where there may be frost) 

Using a large amount of reinforced steel mesh underlayment underneath would probably work just fine anyway since only one side will face outward toward whatever hazards exist outside (assuming yours isn’t an open structure).

Steel Pipes

If you have a large greenhouse, steel pipes are your best bet for an anchor. They’re strong, durable and long-lasting. 

But they were also expensive! If you don’t have the budget for steel pipes, consider using rebar instead.

Rebar is cheaper than steel pipes, but it’s not quite as strong or durable as its metal counterpart. However, rebar can be used in many different ways and places around your greenhouse that would be impossible with steel pipe (for instance, attaching panels together).

InstallationRequires digging and securing
StabilityProvides excellent stability
VersatilityVersatile for various anchoring purposes

Thick-walled Plastic Pipes

While metal pipes are more durable than plastic, they’re also heavier and more difficult to carry. If you’re looking for a quick way to strengthen your greenhouse, plastic pipes are the answer. 

They come in all sizes and can be easily cut for custom installations. Plastic pipe is also easier on your budget you can find them at hardware stores or online for between $10 and $20 per roll of 50 feet. 

You’ll want a roll that matches your greenhouse’s dimensions; if possible, buy extra pipe so that you have some flexibility when installing it.

If you’re using plastic pipes as anchors (rather than to support columns), look for ones that have been reinforced with fiberglass mesh inside them this will make them even sturdier than regular plastic tubes

Concrete surfaces can pose unique challenges when it comes to tent anchoring.

Wooden Stakes and Blocks

Wooden stakes and blocks are a great option for your greenhouse plantings. They’re less expensive than metal ones and they don’t rust. 

Wooden stakes can be used for small or large greenhouses, flat-roofed or sloped-roofed greenhouses pretty much any kind of greenhouse you want!
