A greenhouse tent can be anchored in your yard in a variety of ways. When it comes to greenhouse gardening, this is only one of the many considerations that you need to keep in mind. Because, after all, they’re making a long-term investment in a greenhouse.

For starters, here are some of the most often asked questions about setting up a greenhouse tent:

How Do You Anchor a Greenhouse to the Ground?

A greenhouse that is being anchored to the ground will need anchor bolts and fastening plugs to ensure that the greenhouse’s foundation is securely secured to the ground. Fixing plugs with a diameter of at least 8mm are recommended. Galvanized bolt-down post supports that come with a fastening plate can be used if the ground is hard and your greenhouse does not have anchor points.

Can You Put a Greenhouse on Grass?

You can, after all. To keep the greenhouse in place, you’ll need to keep the ground anchors concreted in place. A greenhouse tent’s integral base is specifically intended to fit into the soil if you obtain the proper kind of greenhouse tent. The top layer of your turf should be removed before setting it up on your lawn.

What’s the Best Base for a Greenhouse?

A strong concrete foundation is the ideal foundation for a greenhouse. It’s not only the most long-lasting alternative, but it’s also the most convenient. Having a large greenhouse above ground level will make it easier for you to maintain it.

Where Should I Put a Greenhouse in the Yard?

On the south or southeast side of your house, this is a fantastic starting point. During the months of autumn and winter, be careful to choose a location that receives the maximum sunlight. The east side of your house is a good place to put your greenhouse, if this area isn’t an option for you.

How Do I Keep My Greenhouse from Blowing Away?

If you set your greenhouse tent in a sheltered area, you can simply prevent it from blowing away. This could be a nook in your backyard or tucked away in the back of your garage. A timber fence or wind netting can be used to enclose your greenhouse if you choose.

Should I Try My Hand at Greenhouse Gardening?

One of the best gardening decisions you’ll ever make is to give greenhouse gardening a try. The advantages of greenhouse gardening far surpass the costs of initial setup, even though it necessitates an investment. It’s time to take a deeper look at the top reasons why greenhouse gardening is a good idea:

You can create an optimum growing environment for your plants

With a greenhouse, you have complete control over the atmosphere in which your plants thrive. This means that with the right techniques, technology, and equipment, you’ll be able to maintain a somewhat constant temperature and humidity inside the enclosure. Aphid parasites and other helpful insects can be kept inside to help their growth, as well as bumblebees and other beneficial nematodes. Lady beetles and green lacewings, army bugs and moth parasites can also be used.

A greenhouse protects your plants from inclement weather, pests, and vermin

An outdoor garden’s moods are constantly in the hands of Mother Nature. In the event of severe weather, such as gales, heavy rain, blizzards, snow, or hail, gardeners will need to be ready to act quickly. To make matters even more difficult, they have to contend with seasonal pests and destructive animals that might undo all their hard work.

You may rest assured that your delicate plants will be safe in a greenhouse because of the structure’s ability to shield them from the elements, bugs, and animals.

It allows you to grow more plants and extend growing seasons

Your plants’ growing season will be extended if you build a greenhouse. Your fruits, veggies, herbs, and flowers will be able to thrive in a warmer climate since you can regulate the temperature inside the enclosure. In addition, you’ll be able to grow plants that aren’t native to your area, such as cacti.

You’ll be able to grow your food

With your greenhouse, you can grow your own food and save a lot of money on groceries. You don’t have to worry about fluctuating prices when it comes to fresh vegetables for you and your family. In addition, you’ll be able to harvest out-of-season items or produce with a larger yield if you’re able to create the ideal growth environment for your plants.

Ways to Anchor a Greenhouse

It is easy to dismantle and fly greenhouses because they are lightweight. A gardener who fails to properly anchor their greenhouse runs the risk of losing not just the building but also the plants growing within. Climate, greenhouse type, and crop needs all factor into which anchoring system is appropriate for your greenhouse. Make sure the greenhouse is in a good spot before anchoring. Light, shade, wind and the positioning of electric and irrigation systems should all be taken into consideration.


The ground can be staked or rebarbed to anchor greenhouses, such as hoop houses and plastic structures, used to cover plants growing directly in the ground. Dig a small ditch the size of the greenhouse’s perimeter for a more durable interim base. In the depression, insert landscaping timber or another type of wood. Anchor bolts inserted into the wood will be used to hold the greenhouse to the foundation after it has been backfilled. If you’re using pressure-treated wood, be sure to check the chemicals used to treat the wood, as some chemicals might seep into the soil.

The stacking and sealing of hay bales is another technique for constructing foundations. Containers filled with sand are also used by greenhouse owners, who either dig them into the ground level with the surface or set them immediately on the ground. Subsequently, the pipe frames are lowered into the storage bins.

There are many inventive ways to anchor a greenhouse utilizing scavenged materials such as heavy tires full of sand, adobe bricks or landscape blocks. Most greenhouse kits offer anchoring materials.

Building a permanent base is required for all types of glass and stiff plastic structures as well as those built in colder climes. Concrete foundations or concrete slabs are used to anchor permanent greenhouses. Most chilly places have a frost line of three feet below the surface. Insulation should be installed before concrete is poured in the ground that is below the frost line.

Digging holes the size of a post in each of the greenhouse’s four corners yields concrete pilings. If the greenhouse is longer than eight feet, additional pilings are required. The post holes should be drilled around 18 inches deep. Add a layer of footing (the base of the piling). The fiber form tube should be inserted into the gap. An inch or so above the hole’s surface is ideal. Insert an anchor bolt into the tube-created column while the cement is still wet. Put in anchor bolts to hold the greenhouse in place.

The foundations and footers are poured first, and then the concrete slabs are built on top of them. Constructing a greenhouse’s concrete slab foundation is quite similar to constructing a home or other long-term building. Make sure you adhere to local building codes and, if necessary, contact an expert.

Securing a greenhouse: the straightforward way

Wind resistance

Your greenhouse or polytunnel is at risk from the wind, which can undermine the structure’s cover. Strong gusts, on the other hand, can penetrate the greenhouse through the air vents and potentially uproot the structure. It is possible for even the tiniest of breezes to weaken or damage your structure.

In most cases, the only way to avoid this is to utilize a sturdy anchoring system that is appropriate for the size of your greenhouse. Of course, a greenhouse intended to contain four tomato plants will not necessitate the same safety precautions as one used in a semi-professional setting. The best course of action is to make sure your structure is well-secured to avoid any mishap.

Trenching your greenhouse cover

Extra material is provided by certain greenhouse and polytunnel manufacturers to be buried in 20-cm-deep ditches. This will, of course, lessen the impact of the wind, but it should only be utilized as a backup plan in conjunction with a well-secured building. For tiny greenhouses, or those erected where wind protection has already been provided, this strategy will be most effective.

Securing a greenhouse with pegs or ground anchor stakes

Many low-cost greenhouses include stakes or pegs for fixing plants. It is possible to use pegs to hold down small greenhouses or low polytunnel-style constructions. Do not hesitate to use a more robust ground anchor stake if you think it is essential.

Using plates to properly secure your greenhouse

Pegs or partially burying the greenhouse cover are the two methods we’ve seen so far for keeping greenhouses secure. However, if you intend to construct a huge greenhouse in a location with limited wind shelter, these techniques will be ineffective. Plates can be used to secure the building to the ground in these situations. These plates are placed around the perimeter of your greenhouse to give structural support, particularly in the face of strong winds.

Ground anchor plates

Ground anchor plates eliminate the need for concrete slabs or another sort of foundation in extremely big greenhouses. The weight of the earth keeps these rectangular plates in place. They’re most commonly utilized on spongy ground to keep your greenhouse from being uprooted.

Base plates

Soft and hard ground can be used to anchor base plates. They’re made up of an anchorplate and two fastening pins for further sturdiness. An anchor base plate and ground tubes are then anchored in place. Only medium-sized greenhouses should utilize this form of repair.

Base plates on concrete

To secure greenhouses to concrete footings or foundations, base plates can also be employed. Fixing plugs or stud bolts are used to keep the foundation in place.

Choosing your fixings to suit your ground surface

Soft ground

Using a frame base

To provide a solid foundation for your greenhouse, consider installing a frame base. It’s true that models with bases are more expensive, but they’re also considerably easier to install!

Assembled, these bases are then buried in the ground. The greenhouse’s frame is held in place by these brackets, which are typically constructed of aluminum. Mixing concrete will be necessary in order to secure the construction. Starting with the feet, dig a hole where you want them to land on the earth. To avoid frost, your holes should be at least 60 cm deep. These holes should be filled with 10- to 15-cm-diameter PVC pipes.

After ensuring that your holes are exactly aligned with the feet of the base and that the diagonals are straight, you can begin building your mortar. Pour it into the pipes and let it set for a while to see whether it can hold the base in place. For the most part it should take less than an hour. It’s possible to incorporate your greenhouse’s attaching plates or anchors into the mortar if you choose.

All that is left to do is to assemble your greenhouse once the base is dry.

Anchoring a greenhouse without a base

If your greenhouse model doesn’t come with a base, you’ll need to secure the greenhouse’s feet into the ground. It’s preferable to rely on your own judgment and go for a model that is both sturdy and long-lasting:

  • Ground anchor plates are perfect for greenhouses with a lot of space. Concrete can also be used to seal these.
  • Small to medium greenhouses make good use of base plates. In order to achieve a more secure grasp, these anchors have pins.

Securing a greenhouse on hard ground

The easiest approach to ensure that your greenhouse will stand the test of time is to secure it firmly to the ground. With or without a base, you can use the hard ground to firmly anchor your greenhouse. Using anchor bolts or fastening plugs with a diameter of at least 8 mm, you can secure the greenhouse’s foundation to the ground.

You can install galvanised bolt-down post supports, which should have a mounting plate, if your greenhouse doesn’t have any anchor points for firm ground.

Spread them out evenly along the length and width of your greenhouse (about three per side), and then insert the greenhouse frame. A threaded rod and a bolt should be used to secure the frame to the post supports.

Six ways to secure your greenhouse

To secure the building, put buried blocks around the greenhouse’s perimeter.

Screw anchors can be used to secure the greenhouse to certain types of ground. According to the size and type of ground, the anchor’s diameter and length will vary.

If the ground is hard, arrowhead ground anchors can be utilized. A hammer drill can be used to embed these harpoon-shaped anchors in the ground.

Anchors can be linked together with stainless steel cables to increase their strength against being pulled out.

Using stud bolts, base plates, or an H-type post anchor, fasten the greenhouse to the concrete slab or foundation. Driving stakes covered with tar into the earth is a simple method of creating anchor points. Use uncoated acacia wood stakes (the most rotproof wood available) for a more eco-friendly approach. After that, you may use coach screws to secure the plates to the wall.
