I just recently posted a response about my 22 year old grapefruit tree that I started from a seed and now I've got a question. I live in Minnesota and so the tree has been in a container indoors all of it;s life for most of the year, outdoors from June - September. I've occasionally had ants and little spiders on the tree but have gotten rid of them with different sprays. Well, last February there was one too many tiny spiders (lots and lots!) and since it was the dead of winter and I couldn't take it outside to hose it off and spray it, I just put it in the garage. We have a garage that's attached to the house and so it never gets colder than around 20 degrees or so. The leaves are all dry but still attached and I didn't water it during it's two month stay in the garage. Now the weather is nice and not suppose to get below 40 degrees at night and so I put it outside and watered it quite heavily. My thought was that the old dead leaves would fall off and new ones would come in their place. Will they? I hope I haven't just killed the tree since it's been with me for so long. Also, if it survives, how long can I expect a tree like this to live?
