Hi everyone I have a ~5 years old orange tree (I live in NYC). Iâ€™ve planted it from a regular super-marker orange fruit. It had a rough life, several times almost died in April each year (reason - indoor radiator heat and dust during the winter seasons). For the last two years, I star keeping my orange tree next to the heated indoor swimming pool in my gym. Last year the tree was infected by spider mite, but Millet helped me. Thanks! This summer (as very other year) I had my tree outside at fire escape stairs until ~ September, then in October (before it drops below 50F) I brought it inside. Just a week later, tiny â€œfutureâ€ leaves at the very tips of the top branches died, but the tree was generally OK. Star loosing â€œmatureâ€ leaves maybe 4-6 a day. So, after a month, I brought it next to pool - and just after a week or two the tree â€œexplodedâ€. Dozens of new leaves, new brunches. New leaves are coming out, while the previous â€œlineâ€ of leaves below are still small, the branches are growing almost Â½ an inch a dayâ€¦ It acts like it Spring already. The questions is: Is this healthy for the orange tree? Does it need a â€œwinter sleepâ€ / hibernation / dormancy (?) which would last for a few months? Again â€“ the tree was in â€œinteriorâ€ lights just for a month, it slowed down, and then suddenly came to a nice, sunny, warm, humid environment and itâ€™s responded to it like is spring. I heard that some tree NEED winter dormancy. Thanks.
