A few weeks ago I posted a related question: "Do loquats only fruit on new growth?"

There was no disagreement with a very straightforward answer from "Applenut":
.

"Mark:

Prune your heart out; there's not much you can do to make it not fruit.

Applenut"

.
I hacked the tree WAY, WAY back, and it's clearly not fazed--it's already begun growing and there will be a ton of new growth prior to flowering.

I hope that if anyone experienced a large drop in fruit production after hard pruning they will speak up. (although I *think* I've heard that some trees produce heavily in alternate years which might complicate things...).

Good luck!

p.s. I didn't know people could get loquats to fruit in 8a. Or do I remember something about a mild winter in Texas or elsewhere?

Actually, it doesn't surprise me that you can grow loquats in that part of Texas--I remember mostly beautiful winters during the short time I lived out there.

However, I'm surprised you are so close to the coast and are zone 8a. There are some zip code zone finders out there that are not terribly accurate, and you might want to look into this.

I remember going through this a year or two. I think the worst may have been that found on the National Gardening Association website:

http://www.garden.org/zipzone/index.php

Where I live, near San Jose, is unquestionably zone 9b. There are always a few frosts, but never anything more than a few degrees below freezing--it always warms up during the day. Now we never get big fronts moving down from Canada like you do, however once every 10 or 20 years things are set up so that temperatures drop into the 20-25 degree range. And that's it--it simply never gets below 20. So everyone will assure you we're zone 9b, however the National Gardening Association program spits out zone 8b--an average low of 15-20 degrees. Impossible. I checked Houston (near downtown where I used to live), Friendswood and Galveston. It also gave 8b to all of these.

You might check the calculator found here on Garden Web:

http://www.gardenweb.com/zones/zip.cgi

I put in Galveston, Friendswood and Houston and all gave zone 9 (as it did for where I live). It doesn't distinguish a and b unfortunately. I suspect you are zone 9a.

At least we can be sure that if the Garden Web calculator were not right, than there would be an uproar from 10,000 people.

I do have to say I was in Houston one year with some temps in the 10-15 degree range (8a temps) but I was assured those were far, far from normal.

I noticed the comments have mentioned that the Loquat can take severe trimming. I wanted to ask the group if that means I can re-size my tree to a smaller profile. Maybe 12 foot and cut out all the inter-twined branches in the middle of the tree. I can appreciate that maybe I should do this in stages; but would like someones opinion before I start ¨ḧacking" away.

My daughter loves this tree and the fruit - so I am willing to proceed with caution in order to stay in her good graces!

Thanks
