from there.
Fimming is Better
It has an advantage over topping in that it provides less stress to the plants and allows them to recuperate faster than when the topping is utilized. Fimming stimulates the plant’s lowest nodes to grow more.
Method 4: Branch Grafting
Branch grafting is another easy method of preventing plants from growing excessively tall. This means joining together two plants with different characteristics except for their heights. It’s also called Tip Grafting.
Things You Need
- To branch graft two plants together, you will need a knife for cutting the stem and long tweezers.
It’s best to use at least three nodes of vegetative growth of both plants involved in the process. The vegetative part is the new healthy stems that have not yet flowered or set their buds on them.
The branches must be the same thickness. If they are not, you should consider doing something else because your success rate will decrease substantially. The stem of both plants involved in this process must also be cut to flat on the surface.
Procedure to Follow
Step 1: Sanitize your Tools
Before you start, make sure to fully clean all tools used with rubbing alcohol or even peroxide. Not only will this help you to prevent the spread of diseases, but it will also create a clean environment that is free from any debris or other contaminants that might affect your graft.
Step 2: Cut the Tops
Cut off the top part of both plants using the knife, and your tweezers should be ready with their lock properly in place. Place one plant on top of the other so that they are perpendicular to one another.
Step 3: Secure and Clamp Them
Secure both plants by winding nylon thread around them to keep them together while the grafting is underway. Once you have done all this, pair your plants with rubber bands and make sure they are still clamped tightly together to form new pathways for nutrients.
Method 5: Keep Lights Closer to The Plants
Plants naturally grow towards sources of light. If you don’t do anything about it, they will grow taller and taller until the point where they will eventually fall over because their support structure cannot hold them anymore.
This can be prevented by keeping lights closer to plants or providing additional support via string or stakes.
- Place the LED grow light about 12 inches above the target plant to begin.
- Examine how the plant leaves react to it. If the leaves droop and curl, you should raise the light a few inches higher.
- However, if the leaves are in good form and growing fast, you might try lowering the light to get closer to the plant, maybe as close as 6 inches from the top of the plant.
These are all the known and approved methods of how to stop plants from growing too tall. If you employ any of them, you will get bigger yields and a healthier and more stable plant.
However, if your main priority is yield, then topping your plants is the best choice for you because it causes the biggest increase in yield potential.
If you try any of the methods given above, please note that while some of them will be more effective than others under certain circumstances, none of them will work 100% of the time.
