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.

Mature size: In habitat up to 8 m tall; in a container typically 0.5–1.5 m over many years

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.

How to tell palo santo needs repotting

Repotting on a calendar is less reliable than reading the plant. For palo santo, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot palo santo

Every 2–3 years, into bone-dry mix. Palo Santo's growth habit — deciduous caudiciform tree or large shrub; develops a swollen, resin-filled trunk with papery peeling bark and small pinnate leaves that drop in winter dormancy. — sets the pace.

What size pot to step palo santo up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Palo Santo stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot palo santo

Spring or summer, while palo santo is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting palo santo

Repot dry. Do not water palo santo for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty very fast-draining cactus/succulent mix with added inorganic grit ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set palo santo at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep palo santo completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for palo santo

Palo Santo wants very fast-draining cactus/succulent mix with added inorganic grit. Use a commercial cactus mix amended 50:50 with perlite, pumice, or coarse grit. The mix must never remain moist for more than a day or two. A slightly acidic to neutral pH of 6.0–7.0 is suitable. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting palo santo — frequently asked questions

How often should you repot palo santo?

Every 2–3 years, into bone-dry mix for palo santo. Repot palo santo every 2–3 years into a snug pot of very fast-draining cactus/succulent mix with added inorganic grit, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does palo santo need?

When is the best time of year to repot palo santo?

Should you water palo santo after repotting?

No — not straight away. Repot palo santo into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise palo santo after repotting?

Not immediately. Wait about 3 weeks after repotting palo santo. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
