I'm stuck with the calamondin... ...Oh and you've never attempted any of them, like the Mexican lime, as bonsai?
Funny you should mention this. I have a calamondin that I am currently in the process of air-layering just above the graft. I am going to evaluate bonsai potential once I see what sorts of roots I get. Calamondin is the only citrus I would consider for bonsai, with the possible exception of the smaller kumquats.
Yes we get a lot of fruit. Last year I pulled 4 x 5 gallon Home Depot buckets off of one tree. We give away a lot, and I have a juicer
Some trees, like the Eureka lemon, will hold their fruit all year. Whenever I need a lemon for cooking or for seafood, I just walk out and pick one. The other trick is to buy varieties based on their fruiting calendar. Try to stagger the fruit so it isn't all coming into season right at the same time. For example I have two loquats (I forgot to list them) that fruit in Feb/Mar, then the peaches in May, then the Valencias in the summer, then the Mandarins around Christmas, etc. The mexican limes and eureka lemons fruit all year.
As far as favorites go, it is hard to beat the Honey Mandarin for flavor. I like the convenience of the Mexican limes for drinks, and Eureka lemon for the kitchen. My wife devours the Meyer's lemons in her sodas - so much so that I had to plant a second tree (they are a lemon/orange hybrid). The peaches are beautiful in the spring, but they are very touchy and susceptible to fungus on the leaves and in the bark. Additionally I don't like how the fruit all ripens in one week. One week and you better be there to harvest and make peach pies, peach cobbler, and peach preserves because if you are a few days late the fruit is past prime and all bad.
