Q.Blood oranges
My blood oranges are about the size of a baseball but still completely green. Just wondering how I will know when they are ripe and ready to be picked. Thank you. My tree is in a pot that I move indoors during the colder weather.
Blood Oranges are mid season fruits, so the fruit is ready to harvest in the months of January and February.
You can check the stem of the fruit; when the stem begins to dry, the fruit is nearing harvest time.
The fruits exact ripening time is dependent on the variety and the environment. They do need the cool evenings to make the blood red color deepen.
Blood Oranges cannot tolerate freezing weather.
