From Madagascar to Chile. A magnificent collector's palm tree. For anyone who wants to be tempted.

Might be planted a tad deep. This species is particularly sensitive to rotting. I’d say it might be safest to dig away a bit of the soil around the stem until you reach the root initiation zone.

Agree , I planted a couple of small ones many years ago and just to the base of the palm. They have done very well . I was warned by a fellow palm enthusiast . Harry

Hard to see this guy with the Caryota in the way . It was planted here as a very young plant . The base of the palm is in a fast draining section of the garden. It is now over 6’ to the crown.

Good air flow around the crown . I think these must come from an arid climate like we have here. I planted two of these , both have done quite well in our 10a climate.

Agree, I lost one due to over watering. They certainly like it a bit on the dry side.

Or very free draining medium, such as pumice, leca, lava and pine bark. If I knew already it many years ago, I would be having now a nice trunking specimen.

They grow pretty well here, at least between record cold fronts. A few of mine made it through. I've started seedlings in cups full of Hydroballs ( 1/4" expanded clay ).

That's right, folks. It's a dense substrate that drains well, but doesn't become waterlogged. You'll have palm trees until you're gone.

Here in San Diego I’ve grown many Dypsis decaryi in the 26 years I’ve lived here and always have watered them very often. I’ve never had one die. I guess I’ve been very lucky. There’s several very large trees in my neighborhood and the only problem I’ve seen on a few is the baterial problem which affects the fronds and eventually kills the tree.

Friend, what pathogen or virus is affecting this palm tree? And what product should be applied?
