3 Ways to Grow Kumquat
Kumquats, small citrus fruits with a sweet, tangy flavor, are both delicious and decorative. They’re especially popular in China, where they symbolize prosperity and good fortune. If you’re looking to grow your own kumquat tree at home, here are three methods that can help ensure your success.
1. Planting from Seed
One way to grow kumquat is by planting seeds collected from fresh fruit. To do this:
a. Obtain ripe kumquats and remove the seeds.
b. Rinse the seeds and allow them to dry on a paper towel.
c. Fill a small pot with well-draining potting mix.
d. Plant the seeds about 1/4-inch deep and water thoroughly.
e. Place the pot in a bright, warm location (ideally around 70°F/21°C).
f. Wait for the seeds to germinate; this can take anywhere from two to six weeks.
g. Once seedlings have emerged, continue watering and caring for them until they’re strong enough to be transplanted outdoors or into larger containers.
2. Growing from Cuttings
Another method for growing kumquat is by taking cuttings from an established tree:
a. Choose a healthy branch tip that’s about 6-8 inches long and contains both leaves and stem.
b. Cut the branch at a 45° angle just below a leaf node (where leaves attach to the stem).
c. Remove all but the top two or three leaves from the cutting.
d. Dip the cut end in rooting hormone powder (optional but recommended) to stimulate root development.
e. Make a hole in moist, well-draining potting mix in a small container, insert the cutting, and gently firm the soil around it.
f. Cover with a clear dome or plastic bag to create a humid environment.
g. Place in a warm, bright area without direct sunlight and maintain high humidity until roots have developed (usually around 4-6 weeks).
3. Grafting onto Rootstock
Grafting is a popular method for growing kumquats because it results in faster fruit production and more vigorous trees:
a. Obtain rootstock and scion material (the young kumquat shoot or bud to be grafted) from nurseries or online sources.
b. Select a compatible rootstock such as calamondin or another hardy citrus variety, ensuring it has a similar diameter to your scion material.
c. Cut the top of the rootstock off with a diagonal cut to match the angle you’ll make on the scion.
d. Make an identical diagonal cut on the scion, ensuring that both cuts are clean and even.
e. Align the cambium layers (the thin layer between bark and wood) of both scion and rootstock, join them together, and press firmly.
f. Secure the graft with grafting tape or rubber bands, making sure everything remains aligned.
g. Monitor the graft while keeping it well-watered until it heals, at which point you can remove the grafting tape.
By following these three methods—planting from seed, growing from cuttings, or grafting onto rootstock—you can successfully grow your own kumquat trees and enjoy their tasty fruit throughout the year.
