How to climb a palm without killing it.

Every palm, sooner or later, becomes a technical problem. The fronds keep growing, the inflorescences fall, weight piles up in a crown that no ground-level ladder can reach. And the question begins: how do we climb?

Anyone who owns a large palm knows this. For years the tree looks after itself, until one day the dead fronds start hanging heavy, the inflorescences drop onto the walkway, the fruit dirties the pool, and the overall posture asks for an intervention. The bud is almost always more than ten metres up, well out of reach of any domestic ladder.

And then the question that reframes everything else arrives: how do we climb up? Because a palm, unlike an olive or a pine, punishes the wrong decision for the rest of its life. This entry explains the three ways to climb, what each one leaves on the trunk, and how to choose well for the palm you happen to have in front of you.

A palm is not a tree

Botanically, a palm is not a tree the way an olive or an oak is a tree. It is an arborescent monocot. It has no secondary growth, no vascular cambium, no annual rings thickening the trunk, and, crucially, it does not heal. What in a dicot is a wound that compartmentalises into new tissue, in a palm stays as a permanent hole in the structure.

This single biological fact, apparently minor, rewrites every care decision: every frond cut, every trunk puncture, every spur stab is a mark forever. The palm cannot repair them. It can only live with them until the sum of wounds, or a pathogen that enters through one of them, ends it.

Three ways to climb

In professional arboriculture practice there are three techniques for accessing a palm. Each one solves the same problem (reaching the crown) in a very different way, and leaves very different traces. They are worth knowing.

The palm climbing frame

The palm climbing frame (in Spain, “bicicleta palmera”) is a pair of articulated stirrups with wide, padded straps that wrap around the trunk. The climber ascends by alternating weight from one side to the other, sliding each strap upward as the other one bears the load. The trunk takes pressure distributed across broad surfaces, with no penetration. Zero punctures, zero mark.

It is the technique most respectful of the tree, and the favoured one for medium-height palms. The cost is time: setting up and ascending with the frame is slower than climbing on spurs, and on very tall palms it asks for serious physical endurance. On Washingtonias or Phoenix under twelve or fifteen metres, however, the difference in time is barely noticeable.

One condition though: for the frame to grip, the trunk has to be previously skinned. On dry sheaths the padded straps slide and the climb stops being safe. Before going up with this technique we always check that the trunk-skinning work has been done on an earlier visit.

The rope

The rope involves anchoring a line at the crown of the palm and ascending on it with mechanical ascenders and foot loops, in SRT (single-rope technique) or DRT (doubled-rope technique) systems. It is the modern arboriculture standard for tall trees. On palms it is used less, because anchoring well in a palm crown is not trivial: the climber has to trust the petioles of live fronds or an artificial structure, and that takes judgement.

When the anchor is resolved well, the rope allows working in positions impossible for the frame, descending under control, and repositioning without going all the way back down. But it has a practical ceiling: above twelve or fifteen metres, setting up a safe crown anchor becomes a huge challenge, and often simply not viable. In the low and medium range the rope shines; above that, the climbing frame takes over.

Gaff spurs

Climbing spurs, also called gaffs, are metal frames strapped to the calf and the foot, with one-to-three-centimetre spikes that stab into the trunk on every step. They make for very fast ascent, with no setup, almost no equipment. They are the standard for telephone poles, for dead trees that will be felled, and, in some regions, also for living trees.

The problem is what they leave behind. Twenty steps up and twenty steps down are forty holes in the trunk. If the palm sees five visits in its life, that is two hundred. On a tree that does not heal, every one of those holes stays open, and together they form a pattern of accumulated wounds that no tissue is ever going to close.

The price of spurs

Spur damage is not visible on the day of pruning. It shows over years. Every puncture is an entry point for soil-borne and air-borne fungi: Thielaviopsis paradoxa, Fusarium species, rots that eat through the vascular tissue from the inside. It is also an open invitation to the two insects that kill palms in Mallorca, Paysandisia archon and Rhynchophorus ferrugineus: both lay eggs on fresh trunk wounds, and spur holes are perfectly shaped wounds for them.

Long-term, a palm that has been climbed several times on spurs loses vigour, becomes more vulnerable to pests, and dies sooner. It is not a theoretical effect. In regions where spur use on living palms is normalised, average lifespans of Washingtonia and Phoenix fall sharply compared to populations cared for with frame or rope.

Why so many palms end up over-cut

On very tall palms, climbing with the frame or with rope is slow, physically demanding, and expensive per hour. The client wants to keep the visit affordable, and the gardener, in good faith, proposes a solution that sounds reasonable: prune more aggressively. Leave the palm almost bare, with only a few central fronds, so that it takes longer to ask for the next intervention.

This excessive cut, known in the trade as a “feather cut” or skirt prune, is a physiological catastrophe. The palm loses much of its photosynthetic capacity, stresses, weakens its defences, and stays more vulnerable just when it would need to be strongest to resist Paysandisia and opportunistic fungi. The client saves one visit and compromises the tree's health for years. The loop closes on its own: the next gardener sees a weaker palm, returns to spurs because “it is no longer worth rigging anything”, and the palm dies before its second century.

How to choose well

A useful rule for the owner, without being an arborist: if your palm is under ten metres, the frame is straightforward and quick, and there is no excuse for anything else. Between ten and fifteen metres, frame or rope are still viable, reasonable options. Above fifteen metres, the technique starts to ask for a specialist, and it is worth paying for a good arborist's hour rather than saving it and signing the tree's death sentence.

The value of the palm almost always justifies the slow decision. A mature Phoenix dactylifera or a Washingtonia robusta in a Pollença estate may be fifty or a hundred years old. Buying another of the same stature is not possible, and planting one and waiting for it to grow is not either. What is lost cannot be bought.

At TerraLuxe we always climb with frame or with rope. Never with spurs on a living palm. It is slower, and sometimes the client notices it in the quote. But the palm lives decades longer, and in a mature Mallorcan garden, that is the only measure that matters.
