There's no such thing as a male loquat. What is happening is that your Gold Nugget is simply very happy while your neighbor's tree is stressed, and therefore it's half the size and it's fruiting whereas yours isn't. Loquats are notorious for not fruiting for the first few years. My Gold Nugget took 5 years in the ground to begin fruiting, even though it was fruiting in the pot before I planted it. If you can't wait, then you might try girdling the tree. But it will eventually fruit, and when it does, you won't know what to do with all the fruit.

Amanogawa, I would agree with the information in the link BigEasyJock provides -- plant your loquat seeds immediately. If the seeds dry out, the plant embryos within will probably die. Most of my loquat grafting attempts have been made with bud-shield grafts -- but I've gotten very low success rates using this method. Some suggest that it is better to employ whole-scion grafts (cleft or whip), using material from twig terminals -- and I think that I may try using this method more in the future. The one time I used it in the past, I got fairly good results.

I planted a seedling from my mom's tree (from So. Cali) in N.Tx, about 4 years ago. This year we actually got flowers and fruit! The fruit are smaller than the one's on my mom's tree, and a little more tart. I do have to mention that I rarely ever water this tree. It has been pretty much neglected it's whole life. I'm guessing that if I do spend some time watering and fertilizing, I'll have larger fruit. The tart flavor can also be attributed to me not waiting till the fruit is fully ripe, but then I do like the tartness of it. My neighbor accross the street got another of my mom's seedlings at the same time. They babied the tree with home made compost and it is beautiful and lush, but only had about 6 fruits on it. Mine is kinda scraggly but loaded with tasty goodness! "about the size of a small lemon or lime " I would consider those GIANT!! Lol!

I have a 6 year old loquat grown from seed that is from many generations of loquats grown from seed. I am interested in having variety. If I grafted a champaign or gold nugget or slim Jim loquat onto it, would the seedling flowers provide pollination? How easy would it be to graft a branch onto it? I want to also keep the original tree.
