if i cut my weed plant will it grow back

Altering a cannabis plant’s photoperiod schedule after harvest will allow you to re-veg it.

Probably the easiest method, this will allow you to harvest a plant for buds and then re-veg it for a second growing season. This is typically done with indoor plants, as you’ll need to control the amount of light they receive.

Cannabis has a short-day photoperiod, meaning it transitions from a vegetative period to a flowering period—when it starts growing buds—because the amount of light it receives reduces. This happens outdoors as autumn approaches and days become shorter. Indoors, growers “flip” weed plants into the flowering stage by manually reducing the amount of light they get each day.

Reduce vegetative periods.

Growers will sometimes keep mother plants, which are plants that always stay in the vegetative stage for the purpose of cloning only. But keeping mother plants takes time and space. Re-vegging allows you to get rid of mother plants, freeing up space in your grow for plants that only produce buds. It also saves time and resources, as you won’t have to tend to mother plants.

When harvesting a weed plant, leave a few healthy buds and branches intact at the base of the plant. Reset the plant’s photoperiod back to a vegetative schedule: 18 hours of light/6 hours of dark a day (as opposed to the 12 light/12 dark schedule it had when flowering).

If cloning a weed plant, growers usually need to take a clone of a plant before it begins flowering. But if a grower neglects to for any reason, that phenotype, or the genes of that specific plant, will get lost. Re-vegging is the only way to preserve an exact replica of a particular phenotype once it has transitioned into the flowering state.

There are a few ways a cannabis plant can revert from its flowering stage back to a vegetative stage.

Most growers who re-veg say that yields decrease the second time around. So while re-vegging may cut down on the amount of time it takes to grow a plant, it might not produce as much.

The re-vegging process is highly stressful on a plant and even if it does re-veg successfully, aberrations often occur, such as unusual leaf growth and hermaphroditism. Re-vegged plants are more delicate and must be given more attention and care.


Cannabis plants will unexpectedly revert back to vegetative growth if there is a disturbance in their photoperiod schedule—for example, if they receive 12 hours of light a day for a while, and then start to get more than that.

A cannabis plant that has undergone a full growing season will have a complex and robust root system. If re-vegging a weed plant, it will move through its second vegetative phase quicker if it has a mature root system, whereas clones or seeds will take longer to establish roots.

The process of taking a clone from a flowering plant is a re-vegging technique known as “monster cropping” (more below), and it can produce more vigorous and bushier plants. If done correctly, monster-cropped clones have the potential to create plants with higher yields the second time around because of an increased vegetative mass, stronger stems and branches, and more nodes for potential buds.

As mentioned above, cloning a plant while it’s in the flowering stage is called monster cropping. To successfully do this, take clones from the lower branches of a plant when it’s in the second or third week of flowering.

Eliminate mother plants.

But it’s possible to hack this process to give cannabis plants a second growing season. A grower can manipulate a plant and force it to revert from the flowering stage back to the vegetative stage again. This process is known as re-vegging, or regeneration, and it allows you to harvest buds from a plant, then grow the same plant again for a second harvest of buds.

Post-harvest re-vegged cannabis plants often take a little bit of time to take off at first and some strains may not even be receptive to this method at all. Early growth on a re-vegged plant may exhibit stress-induced mutations like single-fingered leaves and odd node patterning, but these issues should go away after a few weeks if re-vegging is successful. Plants that re-veg successfully can display increased vigor after the initial transition.

How to:

Cannabis is an annual flowering plant, its life cycle limited to just one season. In the wild, it grows from a seed, flowers, and dies, all between spring and fall. Once a female plant dies, it will drop seeds, which are responsible for carrying genes through to the next growing season.

This can occur both indoors and outdoors, usually because of a light leak or a light timer malfunction when growing indoors, or from planting outside too early in the season when growing outdoors.

Most growers know the most significant flowers (buds) will grow when sun exposure and airflow are optimal. Knowing that, it makes perfect sense to start your pruning at the lower branches of the plant.

Pruning marijuana plants is not difficult to understand, but it does take some dedication and energy as well as using the right tools and timing. Read on for our top tips on how to prune marijuana to enjoy a bounteous crop of premium product.

Proper pruning will help augment your marijuana plants’ natural growth. With careful cutting, you can help your plants send their energy to the places where it is most needed.

Getting Better Bud.

You can even prune the outside branches of the ganja plant to give it an even look. If you are planting in a Screen (or Sea of Green) of Green, where you train the mass of plants to grow up through a wire or plastic grid that would be supported three or four feet above the ground for support, the same principles and methods of pruning apply.

Leave most of the largest fan leaves on the plant. They are the plant’s fuel factory. Removing yellowing, fading leaves and ones that shade the buds only. Keep in mind that while you are pruning, you should always be trying to eliminate the chance of shocking the plant, which may trigger early flowering that might result in lower yield.

The first stage of growth for any plant is the vegetative stage, when all the plant’s energy and biological intensity are telling it to reach a certain size. If the factors above are met, and the watering system operates well and is programmed correctly, growers can prune their plants for maximum yield during this vegetative period.

By using the best, cleanest and sharpest pruners (I recommend Felco or Fiskars brands) for cutting lower interior branches, you’ll end up with a clean cut with very little chance of introducing disease. When snipping off lower interior leaves, using pruning snips or fine scissors is preferable.

Keep in mind that all plants have a “game plan” for how they will grow from seed to flower. A week before pruning and a few days after, ease off fertilizing your plants so you don’t shock them and force them to produce bigger and more leaves right away. A seven-to-10-day period around pruning time will allow them to adjust and then continue a robust growth cycle.

Best of all, pruning costs little or nothing. All you will have to do is invest a little of your time. For many folks, pruning is fun as well as rewarding. Spending a little quality time with your plants and making some judicious cuts can be a win-win. You will also need to get high-quality pruning clippers if you don’t already have them.

In the flowering stage, growers feed their plants an organic high-phosphorous fertilizer. Vitamin B1 helps your plants take up and assimilate phosphorous. Kelp and other plants from the sea are a natural and organic source of vitamin B.

Vegetative Stage.

Carefully pruning your cannabis will help you maximize the growth and potency of every plant. This is just one of the many important factors to be aware of when growing nature’s gift, ganja. Seed (variety), site selection, soil and a regulated irrigation and fertilizing schedule are the other factors that can help you pull off a harvest you can be proud of.

If you’re pruning because you’re planting in a very windy area or you simply don’t want your neighbors or others to see the plants, you might want to keep the height of your plants low. Pinch off the tallest main stalks with a very sharp pair of pruners. Go down the branch two to four bracts (about one or two feet) and make a clean cut.

Begin at the innermost part of each lower branch, where buds may form but will never get large or dense. This pruning technique will send the message to the plant to give all its attention to the outermost buds. The inner leaves that get very small amounts of sunlight are expendable and should be picked off, helping marijuana plants use all of the available nutrients for producing the heaviest, tastiest and most potent harvest, regardless of whether it’s grown for medicinal or recreational purposes.

These factors are all crucial in raising healthy pot plants. But there is another smart, fun and easy way you can give an assist to Mother Nature and help ensure your carefully selected, planted and nourished plants will thrive. Proper and correct pruning can help ensure healthy, bushy plants that produce lots of glorious buds.

Finally, water your garden after pruning or de-leafing to stimulate growth and avoid shock. Giving your plants a dose of Vitamin B complex fertilizer along with the water will help them through this beneficial but often shocking period. The roots will benefit from this nutrient, and the plants should be higher-yielding. This vitamin fertilizer is thought to help the plants grow larger and produce bigger, more resinous colas.

Use Proper Pruners.

There are many important factors to think about and then implement when growing cannabis for maximum yield. There’s aspect: south-facing sunny (eight to 10 hours) location. There’s the dirt: a rich organic and water-retentive soil that has a balanced blend of nitrogen, phosphorus, and potassium. There’s getting the best variety for your climate, your taste and your customer’s tastes from seed, tissue culture clones or ready-to-plant starts from a reputable nursery.

Leaves are where sun-induced photosynthesis takes place and where nutrients are stored. Be careful not to take off all the leaves you plan to remove at one time. Focusing on the lowest branches and the interior of the plant or leaves that shade the buds, make it a two-part process. Each step should be a week apart.

Once you’ve figured out all of these factors, and the danger of frost is over, it’s time to check a moon calendar and plant or soak seed by a new moon to take advantage of Mother Nature’s power.

A little extra care and time spent pruning can pay big dividends in a big, high-quality crop. Just ask any dedicated gardeners or growers, and they will tell you about the dedication and nurturing required and the ultimate payoff. You can do it!

any idea thanks!

ok so a buddy of mine came to my house with a weed plant, but when i seen it it didnt look like no weed plant, it was in a pot with only the stem sticking out of the soil no nodes no leafs But a massive root system seems like the plant was cut off, i was wondering if it is possible if it can re-grow? idk if it can grow New nodes and leafs wondering if its possible for it too??

if there is nothing left then i’d GUESS no. it is possible to Re-Veg a plant, i’ve seen it done, they leave the lower 1/3 of the plant including some of the lower bud sites and revert it back to 18/6 (or disired vegging hours) . 4 weeks later you have a nice looking plant again . however.


yeild is decreased from what i’ve heard the root system will be old, so it won’t perform aswell. also you’ll have to feed her correctly as you won’t have anything left in the soil for it to feed on.

it is possible but its just not worth the agro! . grow a mother and take clones from it . much more economic.
