How to stop plants from growing tall is a question that frequently stumps people who are interested in maintaining a certain height of their foliage. Plants can grow to unmanageable heights at times; however, they can easily be tackled with straightforward garden measures.
We will share their knowledge with you step-by-step throughout this guide on how to stop house plants growing too tall. Keep reading if you want more information on the processes, which will help ensure they remain healthy yet retain the desired height.

How To Prevent Plants From Growing in Height?
To stop plants growing tall you can prune during their vegetative stage, undertake low-stress training, reduce the levels of lights closer to the plant, and restrict. Aim to cut back on the roots, fim the top of the plant, and you can also place it in containers.
– Prune the Leaves
Pruning is a task that requires cutting back the growth of a plant, and when you do so, it is the most straightforward approach to keeping the size of a plant to a level that is more manageable. In this case, you would be wondering, how do you cut a plant that is too tall, the first step would be to leave the plant until it has reached the size you deem appropriate for the available space.
Then, you should aim to make clean cuts to the crown without damaging any buds or nodes.
For this, you are going to need some pruners that are both sterile and extremely sharp. Moreover, remember that pruning regularly ensures your plant remains at the height it had when it was first planted.
In fact, plants such as marijuana plants and cannabis plants grow to be rather tall, and trimming is an effective technique for controlling their height.
– Reduce the Amount of Light
How do I stop my outdoor plants from growing taller, this is another worry that you can have, but this would bring with it another approach that is different. A plant grown in an environment with a high light level will mature more quickly than one grown in an environment with a lower light level.
As a result, this would reduce the amount of light exposure, and in the end, you are going to have its height stunted.
On the other hand, if you want to slow down the rate at which indoor plants develop, you could relocate them into a place with different settings which would be slightly darker, such as by moving them away from a window or grow light source.
You should, however, only move it at a relaxed pace, a bit at a time in order to avoid stress to it. A plant that is subjected to light that is lower will still continue to be healthy but will develop at a slower rate, and this means that it wouldn’t grow as tall anymore.
– Divide It
After reaching a specific size, the individual sections of some plants, such as ferns and peace lilies, can be detached from the rest of the plant and grown separately. You will first need to take the plants out of their container, and then you will need to divide the roots of the weed plants as well, because it’s the same process.
Once you have separated the plant into its parts, you will be left with several smaller plants, instead of one tall plant, that you can either relocate to different areas inside your home or give away to various members of your family and friends.
– Low-Stress Training
A plant is bent over and subjected to minimal pressure during low-stress training. This pressure is insufficient to break the plant’s stem or stalk; however, it is enough to prevent it from growing as a tall plant. The right time to do this training is when the plant reaches a height of six inches, don’t risk the process if it isn’t at this height.
Continue to direct the plant’s growth towards the bottom of the container by bending it over as it gets larger. While doing this, you must carefully secure the plant by tying it down without digging into it.
Moreover, if you have a container or pot that is relatively large, you can lay down approximately two inches of the stem of your plant. This method is one that ensures that the plant will produce a more significant number of bud sites than it would have, but of course, quite shorter.
– Topping
Topping is very similar and is performed on the plant when it is approximately twelve to eighteen inches tall and has around three nodes, the plant’s branch levels. Finding the topmost, central point of the plant’s growth shoot is the first step in the topping process, which prevents plants from growing too tall.
Basically, tackling this part will ensure that the height would not aim to reach any higher after this process.
Make sure that you would remove the core of the growth shoot while preserving a stalk that is a few centimeters or a quarter of an inch above the highest branch line. When this is done, it ensures that a new location for growth has been established and that this unique point will become where it will branch off into a couple of stalks rather than the ones there before.
The key to this strategy’s success is removing all of the growth shoots while preserving some of the stems, and this will prevent the plant from growing any taller than it already is.
When is it too late to top your plant?
The answer is it must be done well before the flowering stage, so that it doesn’t have the given period to grow and thrive, and you shouldn’t cut it when it is actually blooming up.
– Cutting Back on the Roots
A root-bound plant should have some of its roots pruned back to prevent it from growing further. The tap roots of the plant should be removed by cutting them off at their base while taking care to remove no more than a third of the thread roots.
At this point in the procedure, you are not allowed to cut or trim the main section of the taproots in any way; however, you are free to cut the thread roots, so that they wouldn’t develop as they are supposed to.
On another note, you should also cut back any dead roots growing in the different parts of the primary root. The reason for the latter is that by doing this trimming process, it is the key solution when you want to maintain a certain plant height, mainly if it is housed in a terrarium or bonsai. By root trimming, you reduce the growth space, and you are guaranteed foliage at a desired height.
– Fim the Plant
As discussed just a moment ago, topping and fimming are two techniques available to those who wish to limit the height of their plants. When you are fimming, rather than cutting off the shoot responsible for the new growth, you should go approximately halfway down the shoot and cut from that point.
When you do so, it allows the node to continue to produce new growth; however, the height is restricted. It places less strain on the plants than the topping method, and plants subjected to the procedure tend to recover more quickly than those that have topping performed on them.
– Place the Plant in Containers
If a tall plant is kept in a container, not only will its growth rate be significantly slowed down, but it will also be prevented from reaching its full potential, because when it is in a medium where there is the liberty to grow more, it will establish and develop a better growth.
Because the roots are confined in a container, they cannot spread out within their grow room and find their sources of nourishment, which prevents the plant from getting tall.
There is only so much room for the roots to spread out, and it gets maintained to an easily controllable size. The plant’s root system won’t be able to spread outside the confines of the container no matter how much you water it, and in short, the plant’s growth will be slowed down.
Conclusion
You are now aware of how simple it is to stop your plants from expanding to an excessive height.
The information we shared in this post is summarized below for convenience:
- Pruning during the vegetative stage, low-stress training, lowering light levels close to the plant, and restriction can all be used to stop plants from growing tall.
- A plant that receives more light than it needs will grow more swiftly than one that receives less.
- Move a plant away from a window or grow lights and into a darker area if you wish to slow down its growth.
- Once they reach a particular size, some plants, like ferns and peace lilies, can be divided into distinct components and grown as individual plants.
- When a tall plant is placed in a container, it will not only experience a considerable slowdown in development but also be unable to develop to its full potential.
Now, you can be sure they won’t get too tall and become challenging to manage by taking these precautions; hence, you must be able to take the necessary actions to stop your lovely plants from growing to highly tall heights. Therefore, rather than waiting longer, acquire those tools and then put them to good use.
