About Noni
Morinda citrifolia · also called Noni, Indian mulberry · tropical
Noni is a fast-growing tropical evergreen tree producing knobbly, pungent fruit used in traditional medicine and juices. It tolerates heat, salt and poor soils, thriving in full sun and high humidity in frost-free climates. It flowers and fruits almost continuously. In temperate areas grow it as a tender container plant kept above 15°C and brought indoors over winter.
Preferred mix: Well-drained, even poor or sandy soil
Why noni needs this mix
Noni is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Noni is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
- A little perlite or bark stops ordinary compost compacting into an airless block over time, which is the slow, common cause of decline.
- It is not fussy about pH or special ingredients; getting the air-to-moisture balance right is what matters.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons noni struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Plain garden soil or a cheap, claggy compost compacts in the pot and slowly suffocates noni's roots.
- A pure peat mix that dries to a hard, water-repelling block is hard to re-wet and stresses the plant.
- No drainage hole turns even a good mix into a stagnant, root-rotting sump.
Reusing tired, compacted old compost or skipping the perlite. A free-draining mix in a pot with a hole solves most "why is it struggling" cases for noni.
pH — does it matter for noni?
Noni is not fussy about pH — a slightly acidic to neutral mix (around pH 6.0-7.0), which a standard peat-free compost provides, is perfectly fine. No testing needed.
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 decent bagged houseplant compost works for noni as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
Drainage and the pot
A pot with a drainage hole and a saucer you empty after watering is all noni needs — the free-draining mix does the rest.
Refresh noni's mix every 18-24 months; even good compost slumps and compacts, and fresh, airy mix is often the simplest fix for a tired plant. When the time comes, our repotting guide for noni covers the timing and technique step by step.

What is the best soil mix for noni?
3 parts peat-free houseplant compost : 1 part perlite : 1 part orchid bark or coco chips (optional). Noni is adaptable, but like most houseplants it still needs air at the roots — a mix that drains freely while holding a working moisture reserve.
Can I use normal potting soil for noni?

Does noni need a special pH?

Should I buy a bagged mix or make my own for noni?
A decent bagged houseplant compost works for noni as long as you mix in perlite for air. The simple DIY ratio above is cheap and more reliable than a budget bag alone.
How often should I refresh the soil for noni?
