Fall has arrived. It’s prime season for most orchids to send out flower spikes.

But what prompts an orchid to burst into bloom? More importantly, how can you encourage your orchid to produce not just one, but multiple flower spikes?

Several factors play a pivotal role in triggering an orchid’s blooming cycle: the presence of growth nodes, experiencing a temperature drop to around 64°F (18°C) for a minimum of two weeks, maintaining a consistent fertilizing routine, ensuring optimal lighting, minimizing stress, understanding the orchid’s genetics, and the strategic removal of old spikes to redirect energy.

In this article, we will delve into each of these seven crucial factors, guiding you on how to coax even the most stubborn orchids into a stunning display, even if they haven’t bloomed in years.

Let’s go!

How can I get more spikes on my orchid?

1. Availability of growth nodes

To produce multiple spikes, the orchid should have grown at least 2 new leaves in the previous vegetative growing season from spring to fall.  This is because flower spikes are produced in new locations on the sides of the orchid stem and not in the same location as the previous spike.  They sprout from the joints of the stem between leaves, usually two leaves down from the crown

Orchid spikes usually sprout from 2 leaves down from the crown

So, if the orchid has grown only 1 leaf in the new vegetative season, it would only produce 1 flower spike.  If it has not grown any leaves at all, the orchid will not send out any flower spikes. 

When the previous spike fade and dries out, the blooming season ends and begins the new vegetative season where new leaves would grow.

Therefore, to trigger an orchid to send out flower spikes in the coming fall, the preparation should start in spring by growing new healthy leaves.

2. Drop in temperature

A drop in temperature in fall or early winter (once dropping down to 64 degrees Fahrenheit (or 18 degrees Celcius) for 2-4 weeks is needed to trigger flower spikes.  It signals the orchid to end vegetative growth and to start flowering.  But the temperature drop is not much to create any stress.

Orchids that are grown indoors with a constant temperature or in tropical climates without much drop in temperature will have difficulties to rebloom.  For hot climates, air-conditioning or a fan to lower the temperature to 64 Fahrenheit (18 Celcius) or below will help.

3. Genetics

Genetics is the major deciding factor for the number of spikes an orchid can produce. 

Not all Phalaenopsis orchids produce double or multiple flower spikes easily.  Some species can only produce one flower spike per season, for example, the Phalaenopsis subgenus of polychilos and their close hybrids. 

Also, a young orchid is less prone to having multiple flower spikes than an older orchid.

The NoID orchids and mini orchids that are usually available in the store are complex hybrids that often, though not always, can produce multiple spikes.  For example, Phalaenopsis Mini Mark tends to have multiple flower spikes, even when they are under stress. Their spikes are tiny though.  This mini orchid is a hybrid between Phalaenopsis Micro Nova and Phalaenopsis Philippinensis.

Phalaenopsis Mini Mark is one of the hybrids that produce many spikes

4. Good fertilizing routine

Proper feeding of nutrients is important for proper flowering. 

A proper fertilizing routine for orchids is to “feed weekly weakly”, which means to feed frequently but on a low dose each time.  A complete fertilizer with NPK macronutrients of nitrogen, phosphorous and potassium, and micronutrients is needed.  Root fertilizing can be combined with foliar feeding.  

Without receiving any fertilizer, orchids may not show any immediate symptoms because they grow very slowly, and also they may get some nutrients from the water and decomposing medium. 

However, nutrient deficiency will at some point manifest in the yellowing of leaves, slow growth, smaller leaf and bloom size, and a lower quantity of flower spikes and flowers.

5. Enough light

It is important to provide enough light for orchids during their vegetative stage from spring to fall to have enough energy to produce multiple spikes. 

For the Northern Hemisphere, the best lighting is eastern exposure, while Southern and Western lighting needs filtering.  Northern exposure would not be enough.  The opposite applies to the Southern Hemisphere. 

For indoor orchids with insufficient natural light, you can supplement or use LED grow lights.

Good lighting will reflect the overall health of the plant and the quality of the bloom.  Without good lighting, the leaves of orchids would be big and dark green, and the flower would be weak and few. 

Note: a difference in day length would not trigger blooming.

6. Eliminate stress

The presence of stress drains the energy of an orchid.  The source of stress includes a recent loss of roots or leaves, pest, and fungal issues, extreme temperature, lack of moisture, lack of nutrients, etc.

7. Remove old spikes to conserve energy

When flowers drop, you have three options: let the existing spike intact, trim it to a node or remove it completely.

So, should you cut off an old spike?

A spike that has turned brown and is dried has absolutely no chance to rebloom on the same stem. It should be removed completely.

For a green spike with a recent drop of flowers, it should also be removed instead of waiting for it to dry out because they consume the energy of the orchid. 

To produce multiple spikes, it is better to divert energy into root development, which makes for a healthier plant and increases the chance of growing new spikes.

The spike should be cut with sterilized cutters at the bottom of the spike, close to the stem.

If the old spikes are kept until they dry out in fall, it is likely that only one spike would be produced in the new blooming season.  Even though the old spike may branch out to secondary growth, the new flowers on the secondary growth are not as impressive.

What’s more, orchids with old flower spikes removed would have better blooms in the next blooming season.

How many spikes can an orchid have?

Common hybrids often produce 2 new spikes at a time. 

But a few Phalaenopsis species can have 3 or 4 new spikes.  Species such as Deliciosa (sp.) have been reported to have 4 new active spikes at one time. 

In some cases, old spikes can last for several years while adding new ones each year.

How long does it take for a flower spike to grow?

It depends on the species.  For Phalaenopsis, it takes around 3 months from spike to bloom.  It could be shorter, depending on the growing conditions, watering, fertilizing, temperature. 

A higher temperature increases the metabolic rate of an orchid which may speed up the speed of blooming. 

Better growing conditions such as lighting, watering, and enough nutrients promote a strong and healthy orchid, which would have more energy to speed up growing their spikes.

Can an old orchid spike rebloom?

If the orchid is big and strong, some Phalaenopsis orchids can rebloom, even on the same stem on a branched spike, 2 to 3 months after the old flowers have faded.  But, the second blooming of flowers would be smaller and less showy. 

Why won’t my orchid grow a stem?

Some people have orchids that have not bloomed for one or even a few years.  Why?

The reason could be the quality of care.  Poor lighting would lead to dark-colored leaves and a very slow growing speed.  Since the orchid does not receive enough lighting, it does not produce enough food and energy to bloom. 

Stress caused by pest attack, root rot or diseases could put the plant in shock.  Instead of focusing on blooming, the energy is diverted into recuperating and growing its vital organs.

The solution would be to put the orchid in a spot receiving good natural lighting.  In the Northern Hemisphere, the best would be the morning sun from an Eastern window or filtered light from a Western and Southern window.  If the natural lighting is not possible, use a grow lamp.

Also, fertilize it weekly, weakly using 1/4th of the recommended strength to prevent nutrient deficiency.  When a spike appears, increase the strength to half the recommended strength weekly.   


To produce multiple orchid flower spikes, the basic principle is to care for your orchid properly by providing good lighting and nutrients to support new leaf and root growth. Orchids will have the energy and resources to bloom only when they are growing under conditions free from stress such as diseases, pest attacks, loss of leaves and roots.  

A temperature drop to around 62°F (17°C) for at least 2 weeks would trigger an orchid to bloom. 

Lastly, know your species because not all orchids can grow multiple spikes.

Happy growing!
