Introduction to cannabis cutting

Cutting cannabis is one of the most important techniques for any grower to promote healthy plants and maximize yields. It includes both pruning during growth and trimming after harvest. By pruning correctly, you can prepare the plant for optimal light and energy distribution, control growth and increase the quality of your harvest.

Understanding the different pruning techniques and how to apply them is crucial to avoid common mistakes and keep your plants healthy.

Why is correct cutting important?

Proper pruning is essential to help plants use their energy more efficiently. By removing excess leaves, exposure is improved, which optimizes photosynthesis. Pruning also promotes better air circulation, which prevents mold and disease.

Targeted pruning allows you to control the growth of the plant and shape it into a form that is ideal for your growing environment. This leads to higher yields, more uniform flowers and better overall quality.

The advantages at a glance

Pruning cannabis offers numerous benefits that go far beyond improving plant growth. By removing unnecessary leaves, the lower parts of the plant can receive more light, which improves photosynthesis and growth. In addition, the increased air circulation significantly reduces the risk of disease and mold growth, which is particularly important in humid growing conditions.

Another advantage is the increase in yield. Targeted pruning concentrates the plant’s energy on producing larger and more uniform flowers. In addition, maintenance is made easier as the plant structure becomes clearer, which makes working with the plants more efficient.

Better exposure: Allows more light to the lower parts of the plant.
Optimized air circulation: Reduces the risk of mould and disease.
Increased yield: Promotes larger and more uniform flowers.
Easy care: Makes the plant structure clearer.

Difference between trimming and pruning

Many growers confuse trimming and pruning, but both techniques have different purposes. While pruning is carried out during the growth phase, trimming is mainly used for post-harvest processing.

• Pruning:
  Remove superfluous leaves and shoots to direct growth and concentrate the plant’s energy.
• Trimming: Removes excess plant material, such as sugar leaves, after harvest to clean and refine the flowers.

When to use which technique?

The decision on whether and when to prune or trim depends on the growth phase of the plant and the individual objectives. Pruning is used in the vegetative phase to shape growth and prepare the plant for flowering. In the flowering phase, pruning should be done carefully to avoid stress.

Trimming only takes place after the harvest to remove unnecessary plant material from the flowers. This not only improves the visual appearance of the flowers, but also promotes quality, as excess leaves can impair drying. A combination of both techniques ensures an optimal end result.

Preparation for cutting

Before you start pruning, thorough preparation is essential to achieve the best results. The right tools and materials, a clean work area and knowledge of the optimal time to prune are crucial to avoid stress for the plants and promote healthy development.

A well-prepared grower can minimize mistakes and ensure that the plants survive pruning well. In this section, you will learn how to prepare optimally.

Tools and materials required

The right tools are crucial to achieve clean cuts and avoid damaging the plants unnecessarily. High-quality, sharp scissors or blades are a must, as is a disinfected working environment to avoid infection. Disposable gloves and clean containers for cut plant material are also helpful.

Tips for disinfection

Disinfecting your tools before cutting is an important step in preventing the spread of diseases and pests. Use alcohol or a suitable disinfectant to thoroughly clean scissors, blades and other tools.

Work in a clean area, free from dust or other contaminants that could harm the plants. Regular cleaning during pruning helps to maintain hygiene and prevent infection.

Time for pruning: Vegetative vs. flowering phase

The ideal time for pruning depends on the plant’s growth phase. During the vegetative phase, you can shape the plant and remove superfluous shoots to promote growth. Pruning during the flowering phase requires more care, as the plant is more sensitive to stress during this phase.

When should you cut?

• Vegetative Phase: Schneide überflüssige Triebe und Blätter, um die Pflanze auf die Blüte vorzubereiten. Diese Phase ist ideal, da die Pflanze genug Energie hat, um sich schnell zu erholen.
• Early flowering phase: Remove only minimal leaves or shoots to minimize stress for the plant.
• Late flowering phase: Avoid pruning, as the plant should concentrate all its energy on flower formation.

Techniques for trimming

Cutting cannabis is an essential step to control the growth of the plant and maximize its productivity. There are different techniques that can be used depending on the cultivation goal. In this section, you will learn how methods such as topping, fimming and lollipopping work and the benefits they offer.

Topping vs. fimming: Differences and advantages

Topping and trimming are two of the most common techniques used to optimize cannabis growth. Both methods promote bushier growth by removing the main tip of the plant to distribute the energy to the lower branches.

Topping: This involves removing the main tip completely. This method encourages the growth of two new main shoots and allows for better light distribution.
Fimming: When fimming, the main tip is only partially removed. This results in several smaller shoots, which makes the plant more compact and distributes flower production over more areas.

Topping for higher yields

Topping is ideal for growers who want larger plants with several main shoots. This method is particularly effective in the vegetative phase, as the plant has sufficient time to recover and form new shoots.

After topping, the plant grows bushier and the lower branches receive more light. This leads to more uniform flower formation and higher overall yields. It is important to top early enough to give the plant sufficient recovery time.

Fimmen for more compact plants

Fimmen is suitable for growers who work in smaller spaces or prefer more compact plants. As the main tip is not completely removed, the plant is less stressed and recovers faster.

Fimming encourages the development of four or more new shoots, which increases the total number of buds. This method is particularly useful if you want to achieve an even distribution of flowers on the plant.

Lollipopping: optimizing light and energy

Lollipopping is a technique in which the lower shoots and leaves of the plant are removed in order to concentrate energy on the upper areas. This method ensures that the plant focuses its resources on flower production instead of wasting energy on unproductive areas.

When and how lollipopping is used

Lollipopping is best carried out in the early flowering phase, when the plant is investing its energy in the formation of flowers. Remove all lower shoots that receive little light and make sure that the upper flower heads benefit to the maximum.

Benefits: Promotes larger and denser flowers in the upper parts of the plant.
Tip: Cut the lower shoots in small increments to minimize stress and avoid overwhelming the plant.

Techniques for trimming

Trimming is the last step after harvest and is crucial to improve the quality and appearance of your flowers. This technique removes excess leaves, known as sugar leaves, that surround the flowers. Proper trimming optimizes the drying process, improves the taste and makes the end product more visually appealing.

Wet vs. dry trimming

There are two main methods of trimming: wet and dry trimming. Both have their advantages and disadvantages, and the choice often depends on individual preferences and environmental conditions.

Wet trimming: The leaves are removed immediately after harvest while the flowers are still moist. This method is faster as the leaves are easier to cut when wet.
Dry trimming: The flowers are only trimmed after they have dried. This requires more patience, but ensures a more precise result and preserves the structure of the flowers better.

When does which trimming make sense?

• Wet trimming is particularly suitable in humid climates to prevent mold growth during drying. This method saves time and is ideal for growers who want to work quickly.
• Dry trimming is ideal in arid regions as it slows down the drying process and better preserves the terpenes and cannabinoids. This method is often the preferred choice for high-quality buds.

Finishing touches: perfect results thanks to manual work

After rough trimming, fine trimming is crucial to remove smaller leaves and debris from the flowers. Small, precise scissors are used to achieve a clean and professional result.

Tips for the finishing touches

Clean, professional trimming requires patience and the right tools. Work slowly and precisely so as not to damage the flowers and at the same time achieve an attractive appearance.

• Sauberes, professionelles Schneiden erfordert Geduld und das richtige Werkzeug. Arbeiten Sie langsam und präzise, um die Blumen nicht zu beschädigen und gleichzeitig ein attraktives Aussehen zu erzielen.
• Even cuts: Cut along the natural shape of the flower to achieve a uniform result.
• Collect the cut-off remnants: Sugar leaves can be used to make concentrates or edibles.

Common cutting mistakes and how to avoid them

Even experienced growers occasionally make pruning mistakes that can affect plant growth and quality. Avoiding common mistakes is crucial to promote plant health and achieve optimal yields. Here are the most common mistakes and how you can avoid them.

Cutting too aggressively

One of the most common mistakes is to remove too much of the plant at once. This can severely stress the plant and significantly slow down its growth rate. Especially during the flowering phase, aggressive pruning can cause the plant to focus its energy on regeneration instead of flower formation.

How to avoid this

• Schneide immer nur kleinere Mengen auf einmal und lasse der Pflanze Zeit zur Erholung.
• Concentrate on superfluous leaves and shoots that receive little light or hinder growth.
• Avoid aggressive pruning in the late flowering phase, as the plant is more sensitive to stress at this stage.

Wrong time

Pruning at the wrong time can have a negative impact on the plant’s growth. For example, pruning during the late flowering phase is problematic, as the plant concentrates all its energy on flower formation during this time.

Errors with tools and hygiene

Unclean or blunt tools can damage the plant and increase the risk of infection. This often leads to growth problems or diseases that weaken the plant.

How to avoid this

• Always use sharp and disinfected tools to ensure clean cuts.
• Clean the scissors regularly during cutting to remove resin residues.
• Work in a clean environment to protect the plants from pests and contamination.

Frequently asked questions (FAQ)

Cannabis should be pruned regularly during the vegetative phase to control growth and remove excess shoots. This can be done every 1-2 weeks, depending on the growth rate of the plant. During the flowering phase, pruning should be kept to a minimum to avoid stressing the plant.

Yes, common mistakes such as pruning too aggressively or using unclean tools can weaken the plant and affect its growth. Make sure to only prune the plant lightly and always use clean, sharp tools to ensure clean cuts and avoid infections.

Topping and fimming each have their advantages. Topping promotes larger plants with multiple main shoots, while fimming produces more compact plants with more buds. The choice depends on your goals and available growing space. Both techniques are effective when used in the vegetative phase.

Not all plants necessarily need to be pruned. If a plant already has a good structure and all areas receive sufficient light, pruning is not necessary. However, pruning is useful for densely growing plants to improve air circulation and optimize growth.

Trimming is not directly decisive for the yield, but it does influence the quality of the flowers. Removing excess leaves improves the drying process and makes the end product more visually appealing. Well-trimmed buds have a better market quality and offer a more intense smoking experience.
