About Burgundy Rubber Plant
Ficus elastica 'Burgundy' · also called Burgundy rubber plant, black rubber plant · tropical
The Burgundy rubber plant is a dark-leaved selection of Ficus elastica prized for thick, glossy foliage that flushes deep oxblood to near-black in bright light. An easy, fast-growing upright houseplant, it thrives in bright indirect light with steady but not constant moisture, and resents cold drafts and abrupt position changes, which trigger leaf drop.
Preferred mix: Well-draining, peat-free houseplant mix
Watch for — Yellowing lower leaves: Usually overwatering or poor drainage. Let the top few centimetres dry between waterings and ensure the pot drains freely.
Why burgundy rubber plant needs this mix
Burgundy Rubber Plant is an easy-going houseplant — it just wants a free-draining general mix that holds some moisture but never stays soggy.
- Burgundy Rubber Plant 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.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons burgundy rubber plant 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 burgundy rubber plant'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 burgundy rubber plant.
