How to Plant Cumquat Seeds


The cumquat, or kumquat, is a small, orange, oblong citrus fruit that is eaten whole. Cumquat skin is mildly sweet compared to other citrus fruits. Cumquat trees are smaller than most citrus trees. They are very attractive, with shiny green leaves and clusters of orange fruit. Each cumquat fruit holds up to five seeds that can be germinated at home to raise your own cumquat tree.

Sprouting Your Cumquat Seeds

Step 1

Cut open a cumquat fruit and remove the seeds.

Step 2

Prepare a planting medium by mixing equal amounts of potting soil and sand. Cut disposable drinking cups down to about three inches tall and punch holes in the bottom for drainage. Fill the cups with the planting medium.

Step 3

Plant the seeds while they are still fresh and moist. Insert one seed approximately ½-inch deep into each cup. Cover the seeds with the potting medium and water lightly.

Step 4

Cover the cups with plastic wrap and hold it in place with rubber bands. Cut a one-inch slit in the plastic wrap to allow for air circulation and watering. Place the cups in a warm place to encourage them to germinate. Keep the soil damp but not wet.

Step 5

Check the seeds after about a week or two for signs of growth. Once the seeds have sprouted, remove the plastic wrap. After the seedlings have three to four leaves on them, transplant each seedling to a larger pot.

Tips and Warnings

  • Cumquats, like other citrus trees, usually are grafted onto hardy, disease resistant root stock. This may make trees grown from seed more susceptible to disease.
