Tree · Citrus × microcarpa

THE houseplant citrus: covered in fragrant blooms AND tiny orange fruit at the same time, all winter, on a sunny sill. Fruit is mouth-puckering raw but makes legendary marmalade and a Filipino cooking staple. The gateway to citrus obsession.

Questions

Calamondin Orange questions, answered straight.

Do I need two calamondin orange plants to get fruit?

No — calamondin orange is self-fertile, so a single plant will set a crop. A second one usually improves yields, but it isn't required.

Is calamondin orange safe for kids and pets?

Calamondin Orange is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. One caveat on this one: Skin oils mild pet irritant. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.

When do you harvest calamondin orange?

Small tart orange fruit nearly year-round, holds on the tree beautifully.

How do you propagate calamondin orange?

Grafted, or from cuttings/layering (seed won't come true).
