Kaffir Lime Tree
I'm new to this forum, because I'm trying to learn how to better take care of my kaffir lime citrus tree. I bought it from a local nursery in Austin almost three years ago and I'm not positive, but I think it might be from a seedling. I can't seem to find a bump anywhere on the bottom trunk to indicate that it's a graft.
Anyway, around October of 2013, the short bush sent up a really tall branch that grew about 2-3 feet within less than a month's time. This was after we had taken it into our home to avoid leaving it in cold weather. We didn't prune it because we didn't know what to do. Now it's March 2014 and we've just started putting it out about a week ago.
The kaffir is now starting to go crazy. The tall shoot has grown another 8 inches in less than a week and I just noticed today that almost all of the horizontal branches have tiny new leaves sprouting from the end.
The tree seemed to grow slowly for the first 2 years until last October when it had the huge shoot. Can the community please help us answer the following questions that we haven't been able to find answers to?
1. Should we prune our kaffir lime tree and if so, should we prune the tall "leader" shoot? It's March and I've read that if we're going to prune the tree, it should happen around this time of year.
2. Should we put it in a larger pot? When we bought it as a small plant, we put it in the pot you see pictured, but according to what we've read, the pot should have been about 20" in diameter.
3. We give it a citrus fertilizer about once every 6 months, because we're not sure if we should do that or not. Do you think it will really help?
4. What can we do to aid the plant in producing fruit? We've read someplace that kaffir trees from seed can take up to 7 years to bear fruit if they're going to do it at all.
Thank you so much for any guidance you can give us!
