What is defoliation of cannabis and what is it needed for now?

Cannabis defoliation is an agronomic technique that involves the controlled removal of large fan-shaped leaves of the plant. Unlike complete pruning of branches, here we are talking about partial removal of marijuana leaves that interfere with the normal distribution of light and air inside the bush.

General information about cannabis defoliation

Many novice growers ask themselves: why trim cannabis leaves at all? The fact is that if the foliage is too thick, the lower branches remain in the shade and do not receive enough energy for full development. Over time, this leads to the fact that the inflorescences in the lower part of the plant become small and weak, and the overall yield falls.

To avoid this, various techniques are used: from selective defoliation to bush formation methods, such as lollypopping. The latter involves completely removing the lower branches and leaves, leaving the plant looking like a “lollipop”: with a bare bottom and a powerful top, where all the nutrients are directed.

Thus, defoliation of marijuana is not just a cosmetic measure, but an important stage in the proper care of cannabis bushes, allowing you to improve ventilation, minimize the risk of mold and create conditions for the formation of denser and more resinous buds.

When and how to do defoliation correctly

Properly trimming marijuana leaves requires knowledge of the plant's growth stages and how removing leaves will affect it. Mistakes can slow down the growth of the plant, so it is important to know when to defoliate cannabis and how much to do.

Key periods for the procedure:

Defoliation on veg

• During the vegetation stage, the plant grows actively, forming new shoots and leaves.
• At this time, only the largest leaves are removed, which completely block the light to the lower branches.
• The procedure helps the bush develop evenly and prevents the side shoots from stretching.

Defoliation on flowering

• It is best to do this in the second or third week after transferring the plant to 12/12.
• At this point, it is important to remove excess foliage so that the buds receive maximum light and air.
• Excessive removal of leaves from cannabis at this stage can weaken photosynthesis, so you need to act carefully.

Many growers ask themselves: "Should I remove marijuana leaves often or just once?" The answer is simple: it all depends on the variety, conditions and goals. Some plants can handle light adjustments, while others need a more aggressive scheme, such as a combination of defoliation and lollypopping.

By the way, another question often arises: When is the best time to top off? This is usually done at the vegetative stage, when the plant has grown stronger and is ready to form new shoots. In combination with defoliation, topping helps to reveal the potential of the bush, directing energy to the right areas and increasing future yields.

Thus, defoliation is not a chaotic "tearing off" of foliage, but a clearly calibrated process that must be tied to the stage of plant development..

Benefits and advantages of defoliation

Proper leaf removal of marijuana brings more benefit to the plant than harm, if you maintain a balance. The main goal of the procedure is to increase the quality and quantity of the harvest. Due to the fact that light and air freely penetrate into the bush, the risk of mold is reduced, and the inflorescences become denser and more resinous.

Key benefits:

1. Improved ventilation for growing cannabis, preventing overheating and fungal growth.
2. Increased light transmission, allowing powerful buds to form even on the lower tiers.
3. More efficient distribution of plant energy: nutrients are directed to the buds, not to useless foliage.
4. Possibility of combining with other techniques (topping, lollypopping) for even greater yield increase.

To make it clearer, below is a table with the main advantages and possible risks of defoliation:

So, defoliation is one of the key secrets of growing marijuana, but only if used correctly. Leaves should be removed gradually so that the plant does not experience much stress, and the effect is manifested in the form of a healthier and more productive bush.
