The fruiting time does vary. Some variables include fertilizer, water, weather, or tree's age. But you often hear the myth: it takes decades for kumquat trees to fruits. Is it true, though?

Not entirely. If you're growing the Golden Bean kumquat, some people have got it to bear fruits after a year or so. If you're growing bigger trees like the Fukushu, it might only take 4-5 years.

This is the video about the "quat" we were talking about:

They got the seeds from eBay & used the Ziploc bag germination method. Under 1.5 year, the tree actually produced fruits. Did we mention: all of this was done in their apartment.

If you want fast-growing kumquats, you can choose these types. This is a myth-buster to some myths saying that it takes 7 or decades for kumquats to fruit.

Some growers have shared that their kumquat grows to over 20ft tall & produces fruits within 5 years. You'll get bountiful crops all year round since. It's certainly worth the wait.


Responses to Readers' Questions

How many times a year do kumquat trees produce?

--> I'd say probably once a year for most varieties. The Changshou (Fukushu) kumquat often flowers twice a year, so it can produce prolific crops almost all-year-round. The trees often bloom in July. And about 3 months after that the fruits will ripen and you'll be ready for harvest. Harvest could be from November to January or December to April because the fruits can hold onto the trees well into late spring. I hope this helps!

For the first time. I have one fruit on my Kumquat tree, but it's still green and almost the size of a lime????

--> First off, congrats–that's good news. Maybe the variety that you have is a mandarinquat?? It's a cross between a mandarin & a kumquat and is much larger. The mandarinquat rind is still sweet. And compared to a kumquat, it's juicier. For a taste test, check out this video if you like. I hope this helps!
