About Philodendron Maximum

Philodendron maximum · also called Maximum Philodendron, Giant Philodendron · houseplant

Philodendron maximum is an aptly named giant species producing huge, glossy, deeply ribbed and rippled heart-shaped leaves that can reach a metre or more on mature climbing plants. A bold statement aroid, it needs space, a sturdy support, warmth, high humidity and bright indirect light to develop its dramatic full-size foliage.

Mature size: Indoors commonly 1.5-2.5 m (5-8 ft) tall on a sturdy support, with mature leaves reaching 60 cm-1 m (24-40 in) or more in length; larger still in ideal greenhouse conditions.

Indoor size vs how big it gets in the wild

Philodendron Maximum does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect commonly 1.5-2.5 m (5-8 ft) tall on a sturdy support, with mature leaves reaching 60 cm-1 m (24-40 in) or more in length. In the ground with no restriction it is a completely different plant — larger still in ideal greenhouse conditions. — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

Philodendron Maximum is a fast grower. Realistically, expect one to three growing seasons — fast vines can add a metre or more of stem in a single good summer. Its feeding profile backs this up: feed every 3-4 weeks in spring and summer with a balanced liquid houseplant fertiliser at half strength to fuel its vigorous, large-leaved growth. reduce or stop in winter. this heavy grower benefits from consistent feeding during the active season.

How to keep philodendron maximum smaller

You are not stuck with the maximum size. For philodendron maximum specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — philodendron maximum takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
Expect to tidy it every few weeks in summer — this is a fast vine that will sprawl if left.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of philodendron maximum should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow philodendron maximum bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for philodendron maximum the accelerators are:

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The philodendron maximum light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When philodendron maximum outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for philodendron maximum:

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the philodendron maximum repotting guide. If you want more of this plant instead of a bigger one, the philodendron maximum propagation guide turns prunings into new plants.
