About Palo Santo
Bursera graveolens · also called Palo Santo, Holy Wood · tropical
Palo Santo is a resinous succulent tree from Ecuador and Peru prized for its fragrant wood. As a caudiciform houseplant it demands bright direct sun, extremely fast-draining soil, and a strict dry winter dormancy. Water sparingly in summer and almost not at all in winter. Frost-tender; best kept above 10 °C (50 °F) year-round.
Preferred mix: Very fast-draining cactus/succulent mix with added inorganic grit
Watch for — Root rot from overwatering: The single most common cause of loss. Soft, discoloured caudex base indicates rot. Remove from soil, cut away rotted tissue, allow to callus for several days, then replant in bone-dry gritty mix and do not water for 2–3 weeks.
Why palo santo needs this mix
Palo Santo stores water in its leaves and stems, so it wants a free-draining, gritty mix that dries out fully between waterings — not a moisture-holding one.
- Palo Santo carries its own water supply in its thick tissue, so the soil's job is to drain fast and then get out of the way.
- Its roots are adapted to short wet spells followed by long dry ones — a mix that stays damp removes the dry phase they depend on.
- A gritty mix also keeps the plant compact and well-coloured rather than soft, leggy and prone to collapse.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons palo santo struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Standard potting compost on its own stays wet far too long for palo santo; the lower leaves and stem base go soft and translucent first.
- Big plastic pots full of dense mix hold a wet core long after the surface looks dry — that hidden wet zone is where rot starts.
- Anything sold as "moisture control" is the opposite of what this plant wants.
Treating palo santo like a leafy houseplant and using plain compost. It needs at least half its volume as grit, perlite or pumice to survive long term.
pH — does it matter for palo santo?
pH is not a concern for palo santo — anything from mildly acidic to neutral (6.0-7.0) works. Get the drainage right and pH looks after itself.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good bagged "cactus and succulent" mix works for palo santo if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
Drainage and the pot
Use a pot with a drainage hole and empty the saucer within minutes of watering. Terracotta is more forgiving than glazed or plastic because it dries the rootball faster.
This mix decomposes slowly, so palo santo only needs repotting every 2-3 years — mainly to refresh the grit and check the roots are firm and pale. When the time comes, our repotting guide for palo santo covers the timing and technique step by step.
