Orchids are popular houseplants known for their beautiful, delicate blooms. Many orchid owners eagerly await the return of flowers each year, but get frustrated when it seems to take forever for their orchid to rebloom. So how long does it really take?
The answer depends on a few key factors:
– The type of orchid
– Growing conditions
– Care and maintenance
In general, most common orchid varieties will rebloom each year if cared for properly. Some impatient growers resort to chemical flowering agents, but this is not good for the plant’s health. With a little patience and TLC, you can get your orchid to flower again in its own natural cycle.
Typical Timeframes for Reblooming
The timing for reblooming varies widely for different orchid types. Here are some general timeframes:
Phalaenopsis – The popular moth orchid will usually rebloom in 6 to 10 months. Flower spikes can last 2 to 3 months.
Oncidium – Oncidiums can rebloom every 6 weeks to 6 months depending on the variety. Spikes last 3 to 6 weeks.
Cattleya – Large-flowered cattleya orchids rebloom once per year. The bloom period lasts 2 to 6 weeks.
Cymbidium – Cymbidium orchids produce flowers in winter every 10 to 18 months. Blooms can last up to 3 months.
Dendrobium – These diverse orchids have different bloom cycles depending on the species. They rebloom every 6 to 18 months, and flowers last 2 to 8 weeks.
Vanda – Vanda orchids are quick rebloomers, flowering every 6 to 8 weeks year-round in ideal conditions. Flowers last approximately 6 weeks.
So you can see there is a lot of variety! Most commonly cultivated orchids will rebloom within 6 to 18 months.
Factors That Speed Up or Delay Reblooming
Why can the same type of orchid rebloom at different times in different environments? Here are the key factors that affect rebloom time:
Light
Bright light is essential for initiating flower spikes. Orchids kept in low light won’t bloom as quickly. Moving an orchid to a sunnier location can encourage faster reblooming.
Temperature
Cool nighttime temperatures help stimulate flowering in many orchids. Maintaining a 10 to 15 degree drop at night accelerates rebloom time.
Humidity
Orchids prefer humid conditions. Mist your orchids daily or place pots on pebble trays to boost humidity. Higher humidity hastens reblooming.
Air Circulation
Stagnant air increases disease risk and slows growth. Place a small fan near your orchids or grow them in hanging pots to promote air movement. Good airflow aids reblooming.
Fertilizer
Feeding with a balanced orchid fertilizer provides nutrients needed for bloom spike initiation. Fertilize regularly as directed to encourage reblooming.
Pruning
Cutting back flower stems after blooms drop allows plants to focus energy on generating new spikes instead of developing seed pods. Timely pruning promotes faster rebloom.
Division
Dividing overcrowded orchid clumps provides room for new growth and flowering. Divide when plants are potbound. Dividing every 2-3 years helps rejuvenate plants.
Species or Hybrid
Species orchids have longer natural rebloom cycles than hybrids. Hybrids have been bred for more frequent flowering. Species can take years to rebloom compared to hybrids blooming annually.
Mature Size
Young, immature orchids under 3 years old are still developing and won’t bloom as quickly as mature plants over 5 years old. Orchids reach peak flowering potential with maturity.
Tips to Get Faster Reblooming
If your orchid isn’t reblooming as quickly as you would like, here are some tips to accelerate flowering:
Increase Light
Supplement with grow lights or move the plant to a brighter location. Avoid direct hot midday sun which can burn leaves.
Use Fertilizer
Apply a balanced orchid fertilizer every 1-2 weeks during the growing season. Provide extra nitrogen to promote new growth.
Monitor Temperature
Try to maintain ideal day and night temperatures. Install fans or heating/cooling devices if needed.
Increase Humidity
Group orchid pots together, use humidifiers or pebble trays, and mist leaves daily to boost humidity around the plants.
Improve Airflow
Use small fans, open vents or windows, and avoid crowded conditions to keep air circulating.
Divide Overcrowded Plants
Gently divide rootbound plants and repot in fresh mix to stimulate growth and flowering.
Cut Spent Stems
Removing old flower spikes right after blooming redirects energy into new spike production.
Don’t Delay Repotting
Repotting before plants get too crowded gives the roots room to support growth and blooms.
When to Worry About Lack of Reblooming
It’s generally not a concern if your orchid hasn’t rebloomed for 6-12 months. But if your orchid hasn’t bloomed in over 2 years despite providing good care, there could be an underlying issue.
Potential reasons for lack of reblooming include:
– Insufficient light
– Excessive nitrogen fertilizer
– Temperatures too high or too low
– Lack of seasonal temperature changes
– Insufficient watering or overwatering
– Potting mix breaking down
– Pests or diseases disrupting growth
– Genetic weaknesses if plant is cloned
The most common fix is increasing light intensity and monitoring watering habits. Repotting in fresh mix may also help. Identify and correct any care issues to get your orchid reblooming again. Seek advice from orchid experts if needed.
When to Give Up and Rehome an Orchid
If an orchid hasn’t bloomed in over 3 years despite your best efforts, it may be time to rehome it. Try giving it away to an orchid collector who can experiment with specialized care. Or donate it to an orchid society or botanical garden for experts to troubleshoot.
Some orchids develop issues due to inbreeding depression that prevent flowering. Viral diseases can also infect clones circulating in the mass market orchid trade. Incurable problems may affect bloom capacity. Don’t discard an orchid with sentimental value, but deciding when rehoming is kinder than watching leaves slowly decline over years without flowers can be hard.
Conclusion
With proper care tailored to their requirements, most healthy orchids will repeat their springtime floral display year after year. Patience is required, as natural reblooming often takes 6 months up to 2 years depending on the type. Provide plenty of indirect light, maintained humidity, ample air circulation, and consistent fertilization and watering to keep your orchids happy. Avoid forcing flowering with chemicals, and let the plant bloom on its own schedule. If your orchid still refuses to rebloom after several years, troubleshoot growing conditions and pests/diseases. Rehoming with an orchid expert may be the kindest option for a struggling plant. Trust in nature’s cycles, and your orchid will reward you with more of its magical blooms.
