cold hardy lime tree for Austin?
I posted this in a different thread but starting a new one with hopes more TX people will chime in with their experience. Thanks to everyone who already replied to me.
I need to get a lime tree, something that produces an abundance of juicy limes like mexican or similar in taste. But I would rather it be cold tolerant, so that I could just cover it occasionally instead of taking it in for the winter. I am thinking patio plant but I could put it in the ground as well. What variety would I want to look for?
On other citrus notes:
I have meyer lemon tree that did alright outside in a pot here in Austin, TX, with temp down to high 20s for a while. This is the first year its flowering, we'll see how its fruits and hopefully I'll like them.
I have a satsuma mandarin in the ground since the last 3 years. It's small yet, 5 feet but skinny. Didn't grow at all the first year and grew most this last year. Not into a bush, just straight up.
No flowers ever but stays glossy green no matter how cold it gets here. Will it ever flower/fruit? Should I prune it to encourage branching?
I fertilize all my citrus with 6-4-6 citrus food twice a year.
