Not all crabapples 'taste bad'...some of the sweetest and/or tastiest apples I've ever grown or eaten are crabs. Just sayin'... it's always worth sampling them to see... you might be pleasantly surprised.

Hi new to florida, Looks like a lychee tree to me. And you have three of them?!

Hello stanofh, Sorry for late reply...never got notice from email about follow up question. In past three years, coldest I can recall is maybe upper 30s/low 40s at nights during winter (but those are extreme cold spells that last for just few days...normally winter nights are upper 40's/low 50s). Strange thing is last year there was only one harvest of the hanging papayas in summer of around 12 fruits...it was surprise just to see fruit after nothing for 3 years. This year we were able to harvest around 20 fruits in spring and I thought that was it...butt now in fall there is another batch of 25+ fruits. Tree top is now probably reaching 12 foot tall, compared to last year when it was probably 7 or 8 foot tall. We don't use fertilizer or any plant food...the only difference in last year versus previous three years is actually less watering. Mother in law owns farm in thailand...she said to only water tree 2 or 3 times a week.

i had a purple plum ... that flowered for 15 years ... and did not set fruit.. until the season it died ... nothing to do with lack of pollinators ... it was an ornamental, rather than fruit tree ... and frankly.. i dont know what to make about that graft job in the second pic ... i spent the first 6 years in my new house.. harboring everything the prior owners left... you know.. for the history ... bahhh on that.. the happiest day in that garden was when i finally got rid of the last nightmare the prior owners planted .. lol ... if you want a fruit tree... plant some fruit trees .. talk to the fruit nuts in that forum ... and if you want a good landscape tree or shrub ... but dont spend too much energy.. trying to rescue this overly mature.. horribly grafted plant ... [btw ... the 'good' plant may have died long ago ... this might be a reversion of the rootstock] ken
