Hi everyone,
I’m hoping for some advice about my golden cane palms. Over time, a few of them have started splitting and drying out at the base — the stems are cracking and breaking off right at ground level. The inside of the damaged stems feels dry and fibrous, not soft or rotted.
They’re planted in veggie boxes under a large tree around the backyard decking in my Melbourne garden, so they’re in fairly shaded, dry conditions with lots of leaf litter around the base. It started with one clump and has now spread to two others.
Does anyone know what might be causing this or how I can stop it from spreading? Could it be root competition, fungal issues, pest
or something else? Any tips on how to save the healthy canes or rejuvenate the plants would be really appreciated!
Thanks so much in advance
Hello @BenN1
Thank you for sharing your question about your golden cane palms.
From your photos and description, this looks like a common problem with golden cane palms (Dypsis lutescens) grown in restricted, shaded, and dry environments. The splitting and fibrous drying you’re seeing at the base of the stems is most likely due to a combination of environmental stress and structural weakness rather than a specific disease. Here’s a breakdown of what’s probably happening and how you can manage it.
Likely Causes
In your situation, the biggest factor is environmental stress. Golden cane palms prefer bright, filtered light and evenly moist, well-drained soil. Because yours are in veggie boxes under a large tree, they’re likely facing intense root competition from the tree above. The tree’s roots can deplete both moisture and nutrients from the shallow planter soil, leaving the palms chronically dry. Over time, this can cause the lower canes to dehydrate and crack internally, giving that dry, woody, fibrous texture you described.
Another contributor could be mechanical stress as palms age or dry out, older canes lose flexibility and split at the base from wind or shifting in the confined box. Unlike fungal or bacterial rot, which turns the tissue soft or mushy, this kind of damage leaves it dry and splintered.
Fungal or pest activity seems unlikely from your photos because there’s no visible soft rot, frass, or bore holes, but prolonged dryness and leaf litter accumulation can encourage secondary fungal colonization if not cleared periodically.
How to Stop It from Spreading
Start by removing any canes that are already split or dead at the base; cutting them off cleanly at soil level helps the plant redirect energy to healthy growth. Next, improve moisture consistency by deep watering once or twice weekly during dry spells. Because the tree canopy limits rainfall penetration, installing a simple drip line or watering directly into the soil around the roots helps maintain hydration without waterlogging.
If you can, enrich the soil with compost or palm-specific slow-release fertilizer to counteract the nutrient competition from the overstory tree. Clearing away leaf litter around the base can improve air flow and discourage fungal colonization.
You can also apply a light layer of organic mulch (like sugarcane or pine bark) to moderate temperature swings and retain soil moisture, but keep it pulled back a few centimetres from the stems to prevent rot.
How to Rejuvenate the Clumps
Golden cane palms often reshoot from the base once stressed canes are removed. Trim the affected canes, maintain even watering, and if possible, increase light exposure slightly by pruning the overhead tree canopy or repositioning the planter to catch more ambient light. New canes should appear from the crown over the following months.
If multiple clumps are affected, consider lifting and replanting some into larger containers or ground areas with better drainage and space, away from aggressive tree roots. This can rejuvenate their growth dramatically.

Hello @BenN1
Here are three plant alternatives that would still provide a lush, tropical look in your Melbourne-garden setting (with shade, tree-root competition, and possibly dry conditions) and that tend to be more resilient than the clumping golden cane palm under such stress.
Lady Palm - This palm is a very good candidate for a more resilient tropical-look plant in shaded or semi-shaded planting zones. It is known for tolerating deeper shade and being more adaptable in cooler or temperate climates. In one guide of “shade-loving tropical plants” it is highlighted as “a tough and drought-hardy palm that prefers a shaded to semi-shaded position”. Because your area is under a tree, with root competition and less light, the Lady Palm’s ability to cope with those conditions makes it a strong option.
Things to note: Give it free-draining soil (even though it tolerates shade) and some watering during dry spells. It won’t form the same clumping golden-canes “screen” effect but will deliver the tropical fronds and palm look in a more forgiving package.
Palm Lily (Special order product / subject to availability) - If you’re open to a slightly different take on “tropical” (not strictly a palm), this Australian native palm lily is resilient and works well in semi-shade. It is suited to humid/moist settings and is less demanding than some of the true exotic palms. According to botanical notes it is a shrub to around 4 m tall, suited to gardens with moist soils in semi shade. Why it might suit your site: Under a large tree you’re likely getting filtered light, root competition, and a soil environment that can be dry and shaded. The Cordyline rubra handles semi-shade and is less likely to show the structural stress (splitting at the base) that you saw with the golden cane palms because it tends to have a more upright single-stem or multi-stem form with less heavy basal “cane” mass.
Things to note: Ensure the soil has some organic matter (to hold moisture) and that mulch is applied to buffer the competition from the tree roots.
Chinese Windmill Palm (Special order product / subject to availability) - For a more substantial palm that gives a strong tropical feel but with more hardiness, this windmill palm is a good choice. According to one guide specifically for Melbourne gardens it’s noted for being “extremely hardy and tolerant”. While your spot under a tree with likely root competition isn’t perfect for any large palm, this species will handle tougher conditions better than many palms.
Things to note: It will still need good drainage, enough soil volume and deep watering rather than just topsoil. Also preferable is a spot with at least some filtered light, not deep dark shade.
If you choose this: Ensure you give it enough space (both above and below ground) and build up the soil so that root competition is minimised. For example, add a raised bed or root-barrier if tree roots dominate.

Hi @BenN1,
I thought I'd add that to me, this looks more like something is chewing the stems rather than a disease. My suspicion would be rats, and that they are after the soft inner heart of the stems.
If that is the case, you might be able to combat them by putting out rat baits.
Let me mention @Noelle to get her thoughts.
