Does this not getting orange color in warm climates apply to other citrus or just satsumas? I have other types and wondering if I should do the same.
On a related note, do citrus need heat or cool to sweeten the fruit? I keep reading conflicting information.
Thanks again!
Citrus peels change color due to the loss of chlorophyll in the peel from cool weather (just like fall leaves up north). I believe you will only have an issue with your early season fruit not turning color. The mid and late season varieties should get enough cold to turn color. Valencias will go from green to orange and then back to green (around June if they make it that long) as chlorophyll comes back into the peel.
As to your other question, it is my understanding that warm weather durring ripening increases sugars while cool weather increases acids (flavor). Its the balance between the two that make the fruit taste good. Some fruits naturally have high sugars and others have high acids. That is why some varieties taste better when grown in California and others taste better when grown in Florida. That being said, a lot of old Crackers say that cool weather makes the fruit sweeter. I wonder if this is just the natural result of the ripening process or if there is an effect from the dry weather that comes with the winter months concentrating the sugars that are already in the fruit. I'm sure that made things crystal clear for you.lol!
Thank you both for your responses and Galatians, this helped me tremendously as I’d never gotten a clear answer on this. What you say makes perfect sense. I’m going to bookmark this thread and report back what I observe with my varieties now that they’re coming into production.
For comparison, I cut up a Ponkan I knocked off the tree and it was much juicer and flavorful but very acidic, with no sweetness. Here’s some pics.
