In this article, you'll learn a complete, detailed and updated guide to prune any type of orchid and perform the necessary care to ensure your plant always remains in its best condition.
When should an orchid be pruned?
El optimal time to prune orchids It depends more on the life cycle of the plant than on a specific date on the calendar. After flowering This is when pruning is most beneficial, as the plant enters a period of rest in which it redirects its energy towards growth and the next flowering.
Consider these factors before pruning your orchid:
- La flower stalk begins to wither or shows yellow, brown or dry areas.
- The flowers have completely fallen and the plant stops producing new shoots.
- Leaves or roots that look yellow, brown, soft, or dry.
Pruning before flowering or while in bloom can stress the plant and reduce the vitality of the flowers. Therefore, always wait until the flowering cycle is over and the orchid shows signs of vegetative rest.
In most species of orchids common in the home (such as Phalaenopsis), this period usually occurs between late summer and early spring, although if your orchid is indoors and maintained in a controlled environment it may vary depending on care and light exposure.
Remember that the signs given by the orchid itself will always be more reliable than any strict reference to dates.
Preparation: Tools and care before pruning
Before starting to prune your orchid, it is essential to have the following on hand: adequate tools and prepare the workspace to ensure plant health and prevent disease transmission.
List of recommended materials:
- Sharp, sterilized pruning shears or tweezersDisinfection is achieved by wiping the blade with alcohol or briefly immersing it in boiling water.
- Cinnamon powder or activated charcoalBoth act as natural sealants, preventing infections and promoting healing.
- Gardening gloves, especially if you are sensitive to contact with plants or pruning products.
- a large container to prevent soil or roots from falling out.
- Specific substrate for orchids, and a new pot if transplanting is necessary.
- Protective goggles if you want to avoid accidental splashes when cutting tough or dry stems.
Sterilization of tools It's absolutely essential, as it prevents the transmission of fungi, bacteria, and viruses that can infect the cuts and weaken the plant. Never underestimate this step.
How to prune orchids step by step
La pruning orchids It involves working on different parts of the plant: flower stems, leaves, and roots. Each case must be differentiated so as not to eliminate areas that are still healthy and can continue to contribute to the plant's life.
1. Prune yellow or damaged leaves
The healthy orchid leaves They are deep green, firm, and shiny. However, they can sometimes turn yellow or brown due to overwatering, nutritional deficiencies, aging, stress, or disease.
To prune them correctly:
- Look at each leaf and find any that are soft, brown, yellow, or look dry.
- Use the sterilized scissors to cut the damaged leaf at the base, near the stem.
- Avoid cutting if there is only a small spot; in this case, remove only the affected area to avoid damaging a leaf that can still photosynthesize.
- Apply a little cinnamon powder on the wound to seal the cut.
2. Pruning dry or withered flower stems
The flower stalks or orchid stems (also known as spikes) are the structures from which flowers emerge. Once flowering is complete, three situations can occur:
- La rod is completely yellow or brown: Cut the entire stem from the base. This indicates that the plant will no longer use it to sprout and will only consume resources.
- The stick is partially dry or yellow, but part is still green and firm: You can cut just above the third knot (counting from the base of the stem) if the upper area is dry. This way, the plant will be able to sprout in the future from a lower node.
- The stem is completely green and vigorous but has no flowers: In species such as Phalaenopsis, it may rebloom from the nodes. In this case, don't cut the rod; simply remove any dry areas from the tip and wait.
How to make the cut:
- Select the cutting point just above a healthy, green node, never too close to the base if the lower part is still alive.
- Make the cut at an angle to avoid water accumulation in the wound.
- Sprinkle cinnamon on the end to prevent infection.
3. Root sanitation: how and when to do it
La root pruning It is done by gently removing the orchid from the pot, which is recommended at least once a year or when the substrate is very compacted, the roots protrude excessively or symptoms of rot are observed.
Steps to prune roots:
- Carefully remove the orchid from the pot.
- Remove the attached substrate to clearly view the root system.
- Short only soft, black, brown or hollow roots. These no longer absorb nutrients and can generate fungi.
- Leave the green, white, or firm roots intact, as they are vital for the absorption of water and minerals.
- Disinfect cuts with ground cinnamon or activated charcoal.
During this process, you can take advantage of the opportunity to move the plant to a slightly larger pot and renew the specialized orchid substrate.
4. Transplanting and care after pruning
Once pruning is complete, especially if the roots have healed, it's time to repot the orchid into new soil and a suitable pot. The pot should have efficient drainage to prevent waterlogging.
Step by step:
- Place the orchid in the pot, taking care not to bend or squeeze the new roots.
- Add the specialized substrate (usually pine bark, perlite, coconut fiber, etc.) making sure to gently secure the plant and fill in all gaps.
- If the plant has been pruned heavily, wait a few days before watering to allow the wounds to heal.
Common mistakes when pruning orchids and how to avoid them
The success of pruning depends largely on avoiding common mistakes that can harm your orchid. Pay attention to the following tips:
- Do not cut healthy parts unnecessarily: Green leaves or flower stems should be kept, as they carry out photosynthesis and can give rise to new flowers.
- Avoid excessive pruning: Do not remove too many leaves or roots at once, as this weakens the plant and stresses it.
- Do not prune during flowering: Wait for the orchid to go dormant after losing its flowers.
- Always use clean and sharp tools.
- Do not overwater after pruning: Let cuts heal for a few days before resuming watering.
How to prune orchids without flowers
When an orchid has lost its flowers but still has healthy stems, you can prune it using a slightly different approach:
- In PhalaenopsisIf the stem is still green, cut just above a healthy node (third or fourth from the base) to encourage a new secondary bloom.
- If the stick is completely dry, remove it from the base.
- In other species, it is usually preferable to let the rod dry completely to avoid the appearance of infections.
Remember to always observe the color and texture of each part to decide the ideal cutting point.
What to do after pruning: care and maintenance
After pruning it is essential to pay attention to the care that ensures the proper recovery of the plant and prepare the ground for the next flowering:
- Place the orchid in a place with abundant indirect light.; avoid direct sun exposure while recovering.
- Control irrigation: Wait a few days after pruning to resume watering normally and do so only when the substrate is dry to the touch.
- Slightly increases ambient humidity If the environment is very dry, you can use a tray of wet stones or a humidifier.
- Avoid fertilizing immediatelyWait at least two weeks before applying a specific orchid fertilizer, and always do so in moderate doses.
- Observe the plant for signs of infection or stress; if you notice soft leaves, spots, or rot, check the substrate and root system.
General post-pruning care and tips to stimulate flowering
Pruning is one of the essential aspects of orchid care, but it's not the only important aspect of keeping your orchid vibrant and blooming year after year. Keep these recommendations in mind:
- Light: Bright but never direct. An east-facing window or one with a translucent curtain is ideal.
- Irrigation: Moderate and always avoiding waterlogging. Use water at room temperature and allow the substrate to dry between waterings.
- Ambient humidity: Between 50% and 70%. In very dry environments, increase humidity by using trays of wet stones or misting (without wetting the flowers).
- Fertilization: Adapt the fertilizer according to the season and the condition of the plant. Choose specific fertilizers for orchids and reduce the dosage during dormant periods.
- Pest surveillance: Regularly check leaves and roots for mealybugs, aphids, mites, and fungi. If they appear, use specific products and isolate the plant if necessary.
