Why prune your marijuana?

Prune your marijuana early and often to keep your plant healthy and to encourage more growth. Pruning also allows you to control the shape of your plant, so you can maximize the amount of light each branch receives. Lastly, pruning can increase air circulation around your plant, which helps prevent mold and mildew.

Here are a few tips on how to prune your marijuana for the best results:

1. Cut off any dead or dying leaves or branches. These parts of the plant are not contributing to its growth, and they can actually lead to infection if left unchecked.

2. Thin out dense areas of the plant by pruning away some of the leaves and branches. This will allow more air and light to reach all parts of the plant, which will encourage even growth.

3. Cut back any branches that are growing too close together. This will again help with air circulation and prevent mold and mildew from developing.

4. Be sure to sterilize your pruning tools before each use, as this will help prevent infection in your plant.

When to prune your marijuana?

Marijuana pruning is an essential step in the cultivation process that allows you to control the shape and size of your plants. It also helps increase airflow and light penetration, which can improve the quality of your final product. But when is the best time to prune your plants?

Before flowering

Pruning your marijuana before flowering will give you better results, but you need to do it the right way.

Marijuana plants are annuals, meaning they flower once and then die. The best time to prune your plants is before they start flowering. Pruning before flowering will encourage the plant to put all its energy into growing new foliage, rather than flowers.

##Heading: During flowering
Pruning during flowering can be beneficial, but it is not recommended for beginners. If you prune during flowering, you will need to know how to properly support the plant so that it does not break under the weight of the new growth.

After flowering

After flowering, you can prune your marijuana plants to make them more bushy. Wait until the plants have flowered and then prune away any leaves that are touching the ground. If you want to make your plants more produce more flowers, prune the tips of the branches.

How to prune your marijuana?

Pruning your marijuana can be a great way to improve the yield and quality of your plants. It is important to prune your plants correctly, however, as incorrect pruning can lead to reduced yields. In this article, we will show you how to correctly prune your marijuana plants for the best results.


Topping means to cut off the top of the plant just above a node. Doing this will cause the plant to grow new branches (or shoots) from that node, which in turn will give you a bushier plant. Topping also forces the lower branches to grow thicker because they have to share the energy and nutrients that the plant produces with the new growth on top.

Here’s how it works: when you cut off the main stem of the plant, it sends out a chemical signal that tells the remaining leaves to produce more chlorophyll. Chlorophyll is what gives leaves their green color and helps them absorb sunlight so that they can convert it into energy for the plant. The more chlorophyll produced, the more energy available for new growth. This is why topping causes such a dramatic increase in growth rate – it essentially supercharges the plant!


FIMing, or “FIMing is Magic,” is a type of pruning that’s designed to produce more bushy, full-bodied plants. The basic idea is to prune marijuana so that it produces more lateral growth (instead of one big cola at the top).

To FIM your marijuana, start by finding a node (a joint where leaves branch out) on a main stem. Using your fingers or a sharp knife, make a 45-degree cut about ¼” above the node. When you do this, you should see two new shoots emerge from the side of the stem. Let these grow for a few days until they’re about 4” long, then cut them back to two leaves each.

As your plant grows, continue to FIM main stems every few weeks. From each main stem, you should see several branches sprout up. These will eventually produce buds all along their length, resulting in a bushier, fuller plant.


LSTing, or “low stress training” is a technique that can be used to train your marijuana plants. It involves bending and tying the branches of the plant in order to keep them low to the ground. This training method can be used on both young and old plants, and it will encourage the plant to grow wider instead of taller. LSTing is a great way to maximize your yields, and it can also help your plant stay healthy and vigorous.

To begin LSTing, you will need to choose a branch that you want to tie down. The branch should be at least 6 inches long, and it should be flexible enough to bend without breaking. Once you have chosen a branch, you will need to tie it down with some string or wire. Be sure to leave enough slack in the string so that the branch can still move slightly.

Next, you will need to bend the branch down until it is touching the ground. You can use your hands to help support the branch as you are bending it down. Once the branch is touching the ground, you will need to secure it in place with another piece of string or wire. You can also use rocks or other heavy objects to help keep the branch in place if necessary.

Once the branch is secured, water your plant well and wait for new growth to appear. You may need to repeat this process several times before your plant has been fully trained. However, once your plant has been trained, it will produce higher yields and stay healthier overall!

Pruning tools

Marijuana pruning is a necessary task for any grower who wants to ensure a healthy and bountiful harvest. While it may seem like a daunting task, pruning your plants is actually quite simple – and we’re here to help. In this article, we’ll teach you everything you need to know about how to prune marijuana plants for the best results.

Pruning tools
First things first: you’ll need the proper tools for the job. A sharp pair of shears is essential for making clean cuts that won’t damage your plants. You may also want to invest in a pair of loppers, which are shears with longer handles that give you more leverage – perfect for larger branches. And finally, a small hand saw can come in handy for removing thicker branches.

Now that you have the right tools, it’s time to get started.


Pruning your marijuana plants is important to ensure they remain healthy and produce a good yield. If you do not prune your plants, they will become overgrown and produce fewer buds. There are two main types of pruning: topping and fimming. Topping involves cutting off the top of the plant to encourage it to grow sideways, while fimming involves trimming the leaves and branches to encourage growth.
