I recently read that from seed Procimequats could start producing fruit in under a year. So, I started wondering, what is the fastest maturing citrus or sexually compatible citrus relative?

I know that Key limes reach maturity in two years and, as far as I know, that makes them the fastest maturing true citrus. Also, I seem to recall reading that Procimequats owe a large part of their quick maturation to Fortunella hindsii (I honestly don't know how quick they mature). So is there anything quicker then the ones I know about?

Currently I have 4 Procimquat growing from seed. The do bloom in the first year, but do not always set fruit. I do have a new seedling that is now 6 inches tall with 5 or 6 blooms and 1 small fruit. Thomasville Citrangequat, although not the fastest to mature, is another variety that is a rapid grower and a early fruiting variety. Mine have bloomed and fruited from seed in the 3rd year. - Millet (1,139-)

I'm not sure but I think that I've been told that calamondins will reach fruiting maturity grown from seed in 3 years under ideal conditions

TRIPHASIA TRIFOLIA - LIME BERRY. produced fruit in just about a year might have been a year two months. its not a true citrus but still related

I had a sunquat fruit in two years from seed and a sour orange three years. The sunquat grew like a weed and had a lot of fruit. The fruit convinced me to topwork it to changshou kumquat.

Hi,

I have a grapefruit grown from seed. It's about 30 years old by now.

The first bloom was after 20 years, and the first fruits I could harvest when the plant was 22 years.

So this seems to be very different from species to species.

A friend grew a grapefruit from seed in the wet humid tropical area of Far North Queensland ( ex banana farm in the rainforest, south of Cairns ). At 4 years old the seedling was 6 m tall, fully fruiting with a 25cm trunk at the base. The only other factor may be that it was a Balinese variety of grapefruit, but seems to be a pretty straight grapefruit type. 4 years is still remarkable, probably a combination of constant seasonal growth, and locally adapted variety ?

Hello pagnr,

a grapefruit will grow much faster in tropical North Queensland than in mostly continental temperate Germany with temps during summer not too often over 30°C (86°F) and in winter sometimes like -25°C (-13°F).

My grapefruit tree, now about 7 feet high, sits in a 25 gallon plastic tub, because during winter it has to move inside a greenhouse with just 5°C (41°F). So no chance to grow fast.
And even in summer, outside in the garden, with mostly too much rain and too low temps, the tree rises just 5-10 cm (2-4 inches) a year.

Growing citrus here in Germany is a hard job.
I have planted 10 different "frosthardy" citrus in my garden this year, hoping for a mild winter (not below -15°C = 5°F). Without a little tent of breather felt and maybe a candle for heating as protection, there is no chance to let the ten citrus survive till next spring!

Greetings from raw German climate

I just started some kumquat and minneola tangelo seeds and was wondering if anyone had any idea how long they take to fruit from seed? I have a feeling the tangelo will take quite a while but what about the kumquat seedlings?

Thanks,
Joe

One of my Microcitrus Garrawayi seedlings is blooming for the first time now! (four years old).

I'm growing seedlings from C.Limon+Paradisi to, both over 15 years old, but no sign of blooming at all...
