How to Make an Orchid Grow A New Spike-1 Little Known Secret

Do you have a stubborn orchid that refuses to grow a new flower spike? You may even have a Phalaenopsis orchid that appears very healthy, except it just refuses to flower!

Keep reading to find out 1 little known secret to “force” your moth orchid to grow a brand new flower spike. It is easier than you’d think!



I’ve been growing orchids for a very long time, and I know that this works because I have used this “trick” many times over the years.

I will have to say there are some Phalaenopsis orchids that bloom reliably every year, and others that don’t.

Plants are individuals just like people, and some plants are…well…a little stubborn and need a little coaxing.

Assuming your growing conditions (namely light and watering) are ideal and you have a healthy plant, if your plant is not blooming, trying giving it a drop in night temperature.

I will give a summary of at the end of this post on growing conditions for these plants, but let me describe how you can achieve the necessary drop in temperature that will often quickly result in a new flower spike on your Phalaenopsis orchid!

In many cases, it is difficult to achieve a temperature drop at night inside our homes. Homes are becoming more and more energy efficient and insulated, and temperatures can often be pretty steady throughout all times of day and night.

How can you achieve a temperature drop at night? Here are some options.



If your weather permits, place your orchids outside in the shade and let Mother Nature do the work for you.

Having a drop in temperature at night for a few weeks will often cause your plant to bloom.

All it takes is a few weeks of night time temperatures in the 55F to 60F range or so (give or take a couple degrees).

You’ll want to keep an eye on the weather and make sure it doesn’t get too cold.

If there is any risk of going below 50F, bring your plants indoors.

Here are a few of my Phalaenopsis orchids summering outdoors.


Not only will the drop in temperature trigger blooming, but your plants will also benefit from increased air circulation, better light, and rainwater which is so wonderful for them!


If you don’t have an outdoor location, or if you don’t want to place any plants outdoors, you can still manage a temperature drop indoors during the night time.

Many years ago while I was living in a different house, we had single paned windows in our basement. Since they were old, single paned windows, they were not very well insulated, so I used this opportunity to my benefit.

I had a couple orchids that were being stubborn and not blooming. I simply placed them right on that windowsill in the Autumn for a few weeks, and lo and behold, new flower spikes started to form!

Typically Phalaenopsis orchids will start to grow new flower spikes in late fall through late winter. Blooming is possible in other seasons as well.

After I noticed the flower spikes forming, I placed them back in their original growing location.

Another option is to place your plants in a location in your home where you can open your windows at night to cool the room where they are growing.

Of course you still need to follow a good care routine, especially when light and watering is concerned or your plant likely will not bloom.

Without enough light, your plant will not bloom.

Ensuring that your orchid has the appropriate growing conditions is vital for blooming as well so don’t ignore this. I’ve created an infographic below as a quick reference guide to help you out.


Of course, when new growth starts to happen, how do you know if you have new roots vs. a bloom spike?

Fortunately I’ve write a post so that you can tell the difference between orchid roots and orchid flower spikes! Photos included!

Thank you for your article. I’ve been waiting and waiting for my orchid to grow a new stem for blooming (not sure what it’s called) since it died off. It is growing new roots and a couple of baby leaves but it doesn’t look perky. I water it once a week by soaking it in lightly fertilized water for 15-20 minutes. If I change the location to a colder room or in my basement should it be in a window? I have one south window in a cooler room in the house and one east window in the basement.

Thank you!

Yes, it should be in a window for sure. Is the east window cooler too? If so, try that one!

This is my first time with an orchid! My daughter purchased it for me a year ago and also purchased this beautiful emerald green (My birthstone) ceramic pot for it was rootbound in it's original pot. She'd also bought the correct mixture to transplant it into, but right now it just look blah. Leaves are just laying there, yes they're green, a new leaf has grown, but it all looks limp. Hasn't flowered or any shoots since the day she gave it to me. Help!! Sherri

Hi Sherri! Is it growing in bark or sphagnum moss? Tell me how you are watering, and where you have your plant situated. We'll get this resolved!

Hi, I’m really enjoying all your tips for growing orchids! I’m a new grower from the UK and have four orchids at the moment along my north facing but bright windowsill. I don’t have any names for my orchids so how can I tell which ones the are? Thanks Sue

Glad you're enjoying them Sue! I'm assuming you have Phalaenopsis? If there are no labels, it's very hard to tell what cultivar or variety they are....there are loads of them....
