About Pandan
Pandanus amaryllifolius · also called Pandan, Screwpine · herb
Pandanus amaryllifolius is a tropical screwpine grown for its long, strap-like fragrant leaves, which lend a sweet, grassy, jasmine-rice aroma to Southeast Asian cooking. Unlike its spiny relatives it has soft-edged leaves and is the only fragrant Pandanus, rarely flowering and never setting seed. It needs steady warmth, high humidity and bright light.
Preferred mix: Rich, moisture-retentive, well-drained mix
Watch for — Brown leaf tips from dry air: Low humidity browns and crisps the strap-leaf tips. Raise humidity and keep soil evenly moist to keep leaves lush and fragrant.
Why pandan needs this mix
Pandan hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Pandan comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pandan struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for pandan — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets pandan dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for pandan?
Pandan prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
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 peat-free houseplant compost works for pandan straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh pandan's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for pandan covers the timing and technique step by step.

What is the best soil mix for pandan?
3 parts peat-free houseplant compost : 1 part coco coir : 1 part perlite. Pandan comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
Can I use normal potting soil for pandan?

Does pandan need a special pH?
Pandan prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
Should I buy a bagged mix or make my own for pandan?
