how to trim weed plants while growing

In time, these side branches can also get topped, which will create even more side branches and make the plant bush out even more. Doing this will also create more bud sites on branches and therefore increase your yields. Generally, a plant will get topped 1-3 times during its life.

If you wait to top a weed plant after it has developed more than seven nodes, the plant will have been putting energy into upward growth that you are just going to cut off, when it could have been focusing on lateral growth that you will keep.

When to top marijuana plants

As mentioned above, pruning removes cannabis leaves and branches that are dead or won’t receive much light. Again, it might feel strange to intentionally cut off bits of your plant, but without the proper amount of light, buds will be a poor quality.

How to trim weed plants while growing

Pruning is almost exclusively carried out during the vegetative growth stage before the cannabis plant is mature and ready to flower. The plant should be well-established in the vegetative phase, measuring approximately 12 inches (30 centimeters) tall with several sets of leaves before pruning is performed. If you’re looking to grow bushy, squat plants, keep the pruning to a minimum.

The elimination of this growth enables the plant to focus its energy on nourishing and strengthening the remaining leaves, shoots, and buds. Successful pruning also promotes greater airflow and light exposure, fostering a more vibrant plant, and forming denser, more cannabinoid-rich buds.

How do you prune cannabis?

According to Robert Connell Clarke, a cannabis cultivation expert, trimming the central stalk represents one of the most common pruning techniques. The tip of the central stalk is removed when the plant has reached its desired length. This removal encourages a bushy, laterally spreading plant, rather than a tall, stringy specimen.

Very small limbs or branches grow around the lower parts of the plant and tend to be atrophied. The removal of entire limbs allows the plant to channel nutrition into the upper stems, leaves, and buds. More air circulates in the lower reaches of the plant, minimizing the risk of mold when growing indoors. Most importantly, energy and growth hormones are directed upwards towards the buds most likely to thrive. This method is colloquially referred to as the lollipop technique or lollipopping. The plant takes on a lollipop appearance: bushy at the top with skinny and sparse foliage toward the bottom.
