How to Identify a New Orchid Root vs. Flower Spike

Something is poking out of the base of your orchid plant. Is it a new root, or—even more exciting—a flower spike? It can be hard to tell the difference, especially for orchid beginners. In a Phalaenopsis orchid, both roots and spikes are usually green when they begin to emerge, which makes it that much harder to distinguish the two.

I’ve found that with orchids, the easiest way to learn is with our eyes. So, I write bearing visual aids.

The long silvery thing in this first photo is a healthy, dry root. And the small green nub you see to the right of the long silvery root is a new root beginning to poke out from the plant stem. New Phalaenopsis roots usually appear with a green tip, and as they grow longer they will become silvery near the base of the plant. If you click the photo to view the larger version, you will see there are actually two new roots coming in – the green one on the right that I already mentioned, and a second one just above the longer silver root.

This next photo shows a brand new flower spike growing out of the base of another one of my Phalaenopsis orchids. It’s a slightly brighter green and a tad flattened, with what looks almost like a tiny mitten at the tip. It’s this mitten shape that, for me, is what most easily distinguishes a root from a spike.

In the third photo you can see both a new root (silver, on the left) and a new spike (green mitten, on the right).

Cool, huh? I’m always excited to see ANY new growth on my orchids – whether it be a new root, spike, or leaf – because new growth is a sign of a happy and healthy plant. Of course I’m keeping my fingers crossed for more spikes, because that means MORE FLOWERS! but I’ll take new roots too. Growing orchids at home sure is a good way to strengthen your patience muscle.

Updated to add: I receive many questions from readers about orchids that have leaves and roots growing off of the spike. These are called keikis (baby orchids), and they can be viable plants on their own once their roots grow long enough. I have written a separate post about keikis and what to do with them. Read all about keikis here.

Update on Phal Rescue Attempt

Remember awhile back when I tried the ‘sphag-n-bag’ method of rescuing a Phalaenopsis orchid, but aborted the effort after a couple of days? After I had removed the orchid from the bag, I potted it in a terracotta pot with sphagnum moss. Based on the advice I got on the Orchid Board, I then decided that the orchid would be better off potted in something that would get better air flow, so I bought a black plastic net pot like this:

The pot only cost me $.80 at a local gardening supply store. Win!

I took the risk of repotting the poor plant yet again (I had been effing with it a lot lately) and placed it into the net pot with moist sphagnum moss. It’s been doing ok like this for the past few weeks – at least, no turn for the worse – and just the other day I inspected it to see if there was any new root growth. Lo and behold, I found a tiny green nubbin at the base of the crown, so it appears that a new root is growing! I may have saved this poor sad plant after all.

I hope I haven’t jinxed the orchid’s health by posting about it just now. More updates to come, whether good or bad.

How to Water a Phalaenopsis Orchid


Phalaenopsis orchid in bloomNOTE: I recommend reading my updated post about how to water orchids. 

Phalaenopsis orchids are the most readily available orchids and tend to be an orchid newbie’s first; however, many of these beauties don’t come with instructions. Proper watering is key to maintaining a healthy and happy orchid plant, so I’m here to offer up some advice on how to water a Phalaenopsis orchid.

First, let me explain the issues with improper watering. When an orchid is over-watered its roots will rot, which prevents the orchid from absorbing water and nutrients; as a result, the plant will die a lot sooner than you’d like. Conversely, under-watering dehydrates the plant and slows its growth, meaning the plant won’t offer up as many of those beautiful blooms. And the blooms are why we buy orchids, right?!

New Orchids: To Repot or Not? That is the Question

Most orchid nerds will tell you that you should repot any brand new orchid almost as soon as you bring it home. This is recommended so that you can take a good look at the orchid’s root system and cut away any rotten roots (see my post on identifying healthy vs. unhealthy roots). Conversely, you may find a really nice set of roots like these:

You may have also heard not to repot an orchid while it’s in bloom. So, what exactly are you supposed to do with these two conflicting pieces of advice when you bring home a new orchid that is in bloom, like my latest orchid purchase?

How to Identify Healthy vs. Unhealthy Roots

Roots are the basis of any orchid plant. It’s very important for your orchid to have a robust root system; the orchid takes in water and nutrients through its roots which in turn allows the whole plant to grow, thrive, and ultimately put out those beautiful blooms.

First I’ll take a moment to show you what roots look like on the most common orchid, the Phalaenopsis (aka moth orchid). Phal roots, when healthy and moist, are a nice green color, like so:
