How To Support Cannabis Plants Outdoors

Every grower wants to harvest big and dense buds, but that can be a problem when growing outdoors. Considering that you don’t have walls or a structure to tie a SCROG net as you would indoors, you’ll have to come up with a way of supporting the extra weight.

1. Why Support Plants Outdoors?

Sometimes when growing indoors, our plants can grow too much in a limited growing space and their buds end up extra heavy, for this reason, growers use techniques to support the branches.

This can also happen outdoors, although then the problem is not the lack of space but heavy buds of your plant.

When growing outdoors growers usually plant in bigger pots, that is because they aren’t limited by space like they would when growing indoors. This allows the plant to grow to its maximum, it will usually take more to flower but the buds will be denser.

A very common problem growers have when growing plants in bigger pots is that the branches can’t support the weight of the extra dense buds. Growing indoors this can be avoided by tying the branches to the sides or top of the growing tent, but outside we don’t have a structure like that.

Cannabis outdoors isn’t limited by space and can grow huge. If you’re growing a high yielder, the branches may not be strong enough to support the buds and snap, this is why you need to provide support, either with bamboo stakes, a trellis net or tomato cages.

Fortunately, there are several ways to support our plants outdoors, this allows us to have bigger yields and harvest extra dense buds.

2. Bamboo Stakes

Bamboo stakes are what growers usually use to support branches. Even though this is a cheap and effective method, be aware that bamboo sticks can rot, that’s why several growers avoid using them.

You can still use bamboo stakes if you’re letting your plants grow for a short time but because they’re exposed to rain and are in the soil, they can rot.

When bamboo rots, it can spread to your plants and they can suffer from mold (like powdery mildew) which can damage your plants and can easily spread to other plants nearby.

3. Trellis Net

Trellising consists of basically Scrogging outdoors, although it can be harder because you lack the structure to do it properly, so you’ll have to build that structure yourself. Even though it sounds hard, preparing the structure for a trellis net is quite simple, and consists only of placing 4 stakes around the plant.

You can use bamboo stakes but if you have a little bit of cash to spend, we recommend using metal stakes, not only they won’t rot but can be reused in your other growing cycles. Depending on the space you have available, you can place the net horizontally or vertically around your plants.

These two methods will support your plant, although when placing it around your plant you won’t be able to control its size like you would with a trellis placed on top of your plant.

When you place the net horizontally (on top of your plants) this will not only support the extra weight but it will also allow you to train your plants like you would in a SCROG.

4. Tomato Wire Cages

Tomato wire cages are pretty similar to placing a trellis around your plant. They will support your plant from every side but won’t allow you to control the height your plant reaches. On the other hand, some growers don’t want to restrict their plant’s height so this is not really a disadvantage.

Wire cages can also be used as a structure to tie the branches to, using string or other materials that won’t damage your plant, you can easily tie the branches to the wire cage, giving the branches extra support.

You can easily find wire cages in hardware stores and they’re fairly cheap, going for around $1.50 each, they can be reused so you won’t have to buy more for your next growing cycle. If you don’t feel like spending money, you can make your own cage, you’ll just need metal wire and you can easily find how to make them on the internet.

5. In Conclusion

Supporting your plants is definitely important when growing outdoors. When growing in bigger pots, your plant will consequently grow more and develop denser buds. If you fail to give support, the extra weight may be too much for your plant and the branches can snap.

Every grower wants to harvest big and dense buds, but that can be a problem when growing outdoors. Considering that you don’t have walls or a structure to

Cannabis naturally grows up in the form of a single stalk. The single stalk then produces a large cola that has smaller colas on its lower branches. Although the natural way of growing cannabis often yields in healthy buds, there are many other methods to increase and improve the yields of a cannabis plant.

Using a trellis is one of the popular methods t hat many expert growers use for healthy and fast growth of cannabis. The technique is not only good for increasing yields but also keeping them strong and healthy. That is why trellising has become a widespread practice when it comes to harvesting cannabis successfully.

Moreover, the practice supports cannabis buds to grow by letting natural light penetrate through the canopy. Using trellises is very helpful to organize your cannabis garden, and this method makes working with plants easier. All you need to do is to use the wooden or metal framework to branch out your cannabis plants.

Before we find out how you can do it, understanding the trellising method is important.


A trellis refers to the framework of metal or wooden bars to support climbing plants. Trellising cannabis has become a popular method to provide support to cannabis plants during their growth. Trellis could be made of a variety of materials, including metal, plastic, wood, bamboo, and rods. The thin framework allows for the manipulation of cannabis plants to help them receive a sufficient amount of natural light to nourish each branch.

In addition to that, topping out a cannabis plant allows branches to spread out while developing multiple corals. A trellis supports the direct growth of the plants by helping them grow into heavy buds from colas. The structure also increases space between the plants.


Trellising can be done using two techniques; horizontal and vertical. Horizontal trellising is usually made of softer materials such as screens or netting. The holes in the material allow cannabis to grow faster through the trellis.

A vertical trellis, on the other hand, uses materials like wood rods, metals, and bamboo to make a solid frame around the cannabis plant. It has connecting pieces that run through the branches and wrap them. This way, plants get the support that they need to develop from buds.


Whether you want to trellis cannabis or indoors or outdoors, the technique can be beneficial for both. If you are looking to increase the volume of your cannabis grows, trellising can be tremendously advantageous.

Let’s take a look at the two growing techniques.


In the typical habitat, plants grow quite close to each other with only one stalk shooting up in the air. Their density is high, which prevents plants from snapping or bending over. This is what affects the size of the yields.

Outdoor cannabis grows can become vast if you manipulate their natural pattern by using a trellis. All you need is to bring some changes to the natural growth pattern of cannabis by topping the plants and creating space between them. It is an excellent way to promote and enhance the bushy growth. Besides this, adding additional space improves the genetics of cannabis and produces top-heavy yields.

For the best results, follow the given steps to trellis outdoor cannabis grows;

Step 1: Use a metal cage to surround the cannabis plant after transplanting it into the final home for the growing season. Make sure you use a sturdy metal cage that is secured with the strong bamboo stakes. The enclosure is for providing support to the large branches that may grow off their central stalk when you top the plant.

Step 2: When the branch grows out of the metal cage, use bamboo stakes to support them. You can use plant tie tape to direct the branches’ growth in one direction when they stretch.

Step 3: Build a frame around your cannabis plant pot to support its branches as they can grow out the pot’s diameter. You can construct square shape frames to cover the pots. Place the frame and use trellising to cover the top and side of the frame.

When branches go through the surrounded trellising, direct them in an upward direction. Angle them in a way they can receive adequate sunlight and grow in the direction that promotes healthy buds.


Top canopy plays a vital role in the growth of indoor cannabis. As the light in the indoor setting remains above the plant, it may leave them underdeveloped.

To prevent that from happening, begin your indoor trellising with organizing the plants into properly-spaced rows. The rows do not only keep plants organized but also helps you access all the portions of the plant during their growing phase. There are grow tables available to help gardeners organize plants in the rows. These tables are an easy way to allow plants to drain excess water quickly. These tables bring plants up to a convenient working height.

Moreover, these tables provide much-needed support for trellising and framing the rows. Once you frame the indoors cannabis plants, trellising them becomes a breeze. Roll the plant, stretch it, and then fasten the trellis on the grow table.

After this, use the grid pattern to direct the plants and support their buds when they start developing through the finely attached trellis. Taking this step allows light to focus strictly on the plant tops. The branches will receive equal light and grow into healthy and large yields.

In a nutshell, the natural pattern of cannabis growth is chaotic and stressful as it is one of the fast-growing plants that chases light. If you do not grow cannabis using proper techniques, the quickly growing branches, density variations, structure, and height may overwhelm you.

Trellising, in this regard, is a smart way to manage the growth process. It improves spacing between cannabis plants and promotes their growth by providing the right amount of light they need for optimal health and development.
