Orange color inside. Very nice. Mostly green skin, just starting to turn yellow. I only have 2 left on the tree (first year it has produced fruit). Do I need to wait for a little cool weather to take the other 2?

In my opinion, there is no "perfect" ripeness. Last year I waited until late fall to eat any of the Satsumas on two small trees, and they were watery and bland.
This year I have been eating a couple a week and right now they are delicious. Sweet with just enough acid bite.

My fruit are yellowish green, but the insides are a nice orange color.

So if you want sweeter fruit, wait a few weeks or more. Cool weather is what causes the skins to turn orange.

I appreciate your helpful reply.

Welcome aboard Kumquat1,

I have eaten so far this year:

Fremont,
Only picked these because they split. Completely green and fairly tart.

Owari,
One of my trees dropped most of its leaves and I picked the fruit. Completly green but nicely sweet. Inside was orange.

Sunburst,
Just because I wanted to. Starting to turn orange maybe 20%. Not as sweet as the Owari and a little tart. I have several more that I will sample throughout the next two months.

All of these trees were planted this year and are at most two years old. I really should have removed all of them but I just couldn't do it.

Good to have another NW Florida member. If you get up this way let me know we can meet up.
