How To Separate Orchids

You can separate orchids by dividing the plant into smaller sections, and this is one of the most rewarding ways to multiply your collection.

No need for fancy tools or a green thumb because separating orchids is a straightforward process when you understand the basics of how these beautiful plants grow.

In this guide, I’ll walk you through exactly how to separate orchids safely, the best time to do it, and the simple steps to ensure your new divisions thrive.

Whether you’re repotting a crowded phalaenopsis or rescuing a keiki from a mother plant, learning how to separate orchids properly is a skill every orchid lover should master.

Let’s dig in and get those roots ready for their new homes.
 

How To Separate Orchids: The Right Way To Divide

The way to separate orchids depends on the type of orchid you own because not all orchids divide the same way.

Sympodial orchids like cattleyas, dendrobiums, and oncidiums grow horizontally with multiple stems, which makes them perfect candidates for division.

Monopodial orchids like phalaenopsis, on the other hand, grow from a single central stem and cannot be divided in the traditional sense, though you can separate keikis that form on the flower spike.

So, how to separate orchids really starts with identifying which growth pattern your plant follows.

1. How to Separate Orchids With Pseudobulbs

Orchids with pseudobulbs, like cattleyas and oncidiums, are the easiest to separate orchids from because they have clear divisions between each bulb.

Look for a natural junction, which is usually a thin rhizome connecting the pseudobulbs.

Before you separate orchids with pseudobulbs, make sure each division has at least three to four healthy pseudobulbs to sustain the new plant.

Gently pull the plant apart or use a sterilized knife to cut through the rhizome, and you’ll have a perfect new orchid ready for potting.

This method of how to separate orchids works best when the plant has outgrown its pot or when you notice new growth at the edges.

2. How to Separate Orchids That Grow Keikis

If you have a phalaenopsis, the best way to separate orchids is by removing keikis, which are baby orchids that grow on the flower spike.

A keiki is ready to be separated when it has at least two to three roots that are about two to three inches long.

To separate orchids with keikis, sterilize a pair of scissors and cut the keiki from the mother spike, leaving an inch of spike on each side of the keiki.

Once you remove the keiki, pot it in a small container with fine bark or sphagnum moss, and you’ve successfully learned how to separate orchids of this type.

This is a fantastic way to propagate your favorite orchid without harming the mother plant.

3. When You Should Not Separate Orchids

Knowing when not to separate orchids is just as important as knowing how to do it.

Never attempt to separate orchids that are blooming or about to bloom because the stress can cause the flowers to drop prematurely.

Also, avoid separating orchids that have fewer than three mature bulbs or pseudobulbs, as they may not have enough energy stored to recover.

If the roots are completely rotten or the plant is severely stressed, focus on rehabilitating it first before you separate orchids.

Patience is key, so wait until your plant is actively growing with new roots and leaves before you attempt any division.
 

Best Time To Separate Orchids For Success

The best time to separate orchids is right after the blooming period has ended and new growth has just begun.

This timing is crucial because the plant is in its most vigorous growth phase, which helps it recover quickly from the shock of division.

Spring is generally the ideal season to separate orchids, as the warmer temperatures and increased daylight encourage rapid root development.

If you live in a climate with distinct seasons, aim to separate orchids in early spring before the heat of summer arrives.

Avoid separating orchids during their dormant winter phase, as the plant is resting and less likely to establish new roots.
 

Step-By-Step Guide On How To Separate Orchids

Now that you know the best time, let’s walk through the practical steps on how to separate orchids from start to finish.

Step 1: Gather Your Supplies

Before you separate orchids, make sure you have everything ready so the process is smooth.

You’ll need a sterilized knife or pruning shears, fresh potting medium, new pots, and a fungicide like cinnamon or activated charcoal powder.

Having these items on hand prevents delays that could leave the roots exposed to air for too long.

Step 2: Remove The Orchid From Its Pot

Gently slide the orchid out of its current pot and shake off as much old potting medium as possible.

If the roots are stuck to the pot, soak the entire pot in water for about 15 to 20 minutes to loosen things up.

Once the orchid is free, rinse the roots with lukewarm water so you can see exactly where to separate orchids.

Step 3: Cut The Rhizomes To Separate Orchids

Now it’s time to make the cuts, so examine the rhizome and locate natural divisions.

Use your sterilized blade to slice through the rhizome at a clean, straight angle, ensuring each section has its own roots and bulbs.

Dust the cut ends with cinnamon or charcoal to prevent fungal infections from entering the wounds.

Step 4: Pot Each New Division

Place each separate orchids division into its own pot filled with fresh orchid bark or appropriate medium.

Hold the orchid so the base of the plant sits just at the surface, and then pack the medium gently around the roots.

Water the new divisions lightly and keep them in a shaded, humid spot for the first couple of weeks.

Step 5: Care For The Newly Separated Orchids

After you separate orchids, don’t treat them like established plants right away.

Keep them out of direct sunlight and reduce watering until you see new root tips emerging from the base.

You can also mist the leaves daily to maintain humidity, but avoid water pooling in the crown, as that can cause rot.

Once new growth appears, you can gradually return to your regular orchid care routine.
 

So, How Do You Separate Orchids At Home?

You can separate orchids at home with just a few simple tools and a bit of patience.

The key is to identify whether your orchid has pseudobulbs, keikis, or a single stem before deciding how to separate orchids.

Always choose the right timing, which is after blooming and during active growth, to give your divisions the best chance of survival.

And remember, the process of learning how to separate orchids is forgiving, so even if you make a mistake, most orchids are resilient enough to bounce back.

With these steps in hand, you’re ready to grow your orchid collection and share these stunning plants with friends and family.

Happy dividing, and may your newly separated orchids flourish in their fresh new homes!
