Chinese money plant

The Chinese money plant comes from the forested foothills of Yunnan and Sichuan in southern China, where it grows in shaded rock crevices. It reached Europe not through the nursery trade but through a Norwegian missionary who carried cuttings home in the 1940s, and for decades it spread from windowsill to windowsill as a plant nobody could name. That history is written into its habits: it makes offsets constantly, roots from almost nothing, and is happiest passed around.

Light

Bright indirect light, out of the direct sun beam. A metre from an east or west window is close to ideal. In too little light the stem stretches, the leaves space out and the whole plant leans; in direct sun the leaves scorch at the edges and cup downwards.

Turn the pot a quarter turn every week. This plant tracks a window harder than almost any other houseplant, and one that is never turned grows into a lopsided thing with every leaf facing the same way. A weekly quarter turn keeps it as round as the leaves.

Water

Water when the top 3 cm of compost is dry, which is roughly weekly in summer and every ten to fourteen days in winter. Soak it until water runs from the base and empty the saucer.

It is honest about thirst. The leaves droop and the stems soften, and the whole plant stands back up within a few hours of a drink. That makes underwatering easy to correct and overwatering the real risk, because a wet pot produces the same droop for a completely different reason. Feel the compost before you water a drooping plant, every time.

Feeding and repotting

Feed monthly at half strength from spring to early autumn, and nothing over winter. Repot in spring, one size up, into free draining compost. A plant surrounded by its own offspring dries out within a day of watering, which is usually the sign that it is time.

The pups

Small plants push up from the compost around the base, and sometimes from the stem itself. They are the reason for the plant’s other name, the friendship plant, and taking them off does the parent good.

Wait until a pup is about five centimetres tall, then work down beside it with a clean knife and cut it away below the surface with a little root attached. Pot it into a small pot of the same compost, keep it just moist and out of direct sun for a fortnight, and it establishes without trouble. A pup that comes away with no root at all will still root in water in two to three weeks.

Pruning

There is little to prune. Take off yellowing lower leaves at the stem, and be aware that an older plant naturally sheds them and develops a bare stem with a canopy on top. That is its adult shape rather than a fault. If you would rather have a low round plant, keep starting new ones from the pups.

Pet safety, honestly

Almost every list on the internet calls this plant pet safe. The ASPCA, which is the source this journal uses for pet safety, lists several other Pilea species as non toxic and does not list this one at all. There are no reports of it poisoning an animal, it is not related to any of the notoriously toxic houseplant families, and the balance of evidence is reassuring. None of that is a listing, so the ledger says not known rather than safe. If you need certainty in a house with a cat that chews, a spider plant or a Boston fern is on the list by name.

Ailments

Curling leaves are a light problem and the direction tells you which way to move it. Yellow lower leaves are either too much water or simply age. A droop needs a finger in the compost before it needs a watering can. Crisp brown edges mean sun or a radiator. The ledger below has the rest, and there is not a great deal of it.
