Every aroid you grow originated somewhere specific. Climbing a host tree, anchoring to a rock face, feeding from a fast-flowing creek. Understanding where they come from changes everything about how you grow them.

“My plant loves being rootbound.”

We hear this one a lot. But what looks like a happy, thriving plant is usually just a stressed one — drying out faster, or pushing into survival mode. Climbing aroids in particular can push out a lot of growth when rootbound, searching for somewhere better to send their roots. This is why our media filled supports are so important for some species. We have all been there and telling ourselves that the plant is happy to put off a repot and save some time can mean it all ends up going a bit sideways... literally.

Swipe through for the full breakdown, including what to actually do when your plant runs out of room.

The best time to air layer a climbing Aroid is 2 months before you think of it.

Air layering is one of the most reliable propagation techniques for climbing aroids — a cutting with an established root system before separation recovers faster, succeeds more reliably, and produces more mature foliage sooner. The problem is most growers only think about it when they’re already in trouble.

But even if propagation isn’t something you’re interested in — you will eventually need to cut your plant. Every climbing aroid outgrows its space at some point. When that happens you want the most fail safe and easiest way to do it. A cutting with an established root mass from a media filled support gives you exactly that.

A well packed media filled support changes the whole equation. Roots are establishing continuously inside the support from the moment the plant starts growing into it. When the time comes to chop, you’re not starting an air layer from scratch under pressure — the work has already been done.

The problems climbing aroids present are predictable. The root mass, the chop, the propagation — none of it has to catch you off guard if you set things up right from the start.

Climbing aroids don't all climb for the same reason. Knowing why your specific plant does, tells you what to prioritise.

It's also why people get confused about whether a plant is actually a climber. Someone growing Monstera deliciosa in a bright spot might conclude it doesn't need to climb — it's producing large leaves, even flowering, without a support. And in that environment, whilst they'd be a nightmare to manage long term, they're not wrong. But that's the light doing the work, not the plant abandoning its climbing habit.

Some climb for light. Philodendron atabapoense and Philodendron billietiae are good examples — given enough light they don't need to climb much to reach maturity. Prioritising light over support height will get you further quicker with these species.

Some climb to escape competition. Philodendron verrucosum doesn't need much light but still needs to climb to mature — likely about the evolutionary advantage of being on a tree rather than light itself.

Some need to climb to stay in mature form. A Philodendron mayoi that grows past its support will start lengthening internodes regardless of light levels. Lose the support and you lose the maturity.

Some climb only to then detach. Philodendron hederaceum and Philodendron chinchamayense need to climb first and then hang away from the host to produce inflorescences. Climbing is part of their reproductive strategy.

This post is still an oversimplification. We can't simply ask a plant why it climbs or what it needs. Growing plants would be a far less interesting endeavour if we could. There are no clean rules — the sooner you stop looking for them and start observing your specific plant, the better a grower you become.

The aroid flower is more complex than it looks. What most people see as a simple spathe opening is actually a carefully sequenced reproductive process — involving heat, scent, specific pollinators, and in some genera, berries that burst out when the time is right.

IRCC (Internal Rapid Cutting Calculation) ... how fast is yours?

IRCC (definition)
The involuntary internal and instantaneous mental calculation triggered by the words "can I get a cutting?" Variables processed simultaneously include: the replacement value of the plant, current market availability, the rarity of the form or clone, the number of viable nodes remaining, the time of year and whether conditions favour successful propagation, the anticipated setback to the parent plant and its current trajectory, the requester's demonstrated horticultural competence, their track record with previous cuttings, the current state and history of the friendship, whether reciprocal cuttings have ever been offered, and an unconscious projection of where the cutting will likely end up in six months.

The entire calculation takes approximately 1.3 seconds while you hold a weird awkward nervous smile.

A negative IRCC score results in the phrase "Let's see how it goes over next summer"

Failing to plan is planning to fail. With climbing aroids, the problems you'll eventually face are completely predictable. The question is whether you're ready for them when they arrive.

Every climbing aroid will eventually run out of headspace. Your support will eventually need extending. The plant will get top heavy. And at some point you'll need to cut the top — either to propagate to sell a cutting or a chop and extend to keep the plant thriving. None of this is a surprise. It's just a matter of when.

The mistake most growers make is waiting until they're in the middle of the problem before thinking about the solution. Trying to air layer a top cut under pressure, scrambling to find a way to extend a support that wasn't designed for it, or attempting to remove a root mass from a support with openings too small to get it out cleanly — all of it is avoidable with the right setup from the start.

Getting onto a good support early is the single biggest thing you can do. The most common question we get is how to get a tall untrained plant onto a support. The honest answer is almost always the same — cut the top and start again with a good support. That conversation doesn't need to happen if you plan early.

This is what makes us different. We've grown hundreds of climbing aroids over more than eight years. We're not a faceless seller on Temu or Amazon who don't grow plants or answer questions. We know the problems you're going to face because we've faced them ourselves — and we designed our supports around the solutions before you even knew you needed them.
