Can't help with the tree but isn't it a LoNgan?

Yes it's a Logan. My bad

it's both logan and longan.... and you'll get more responses under the tropical fruit trees forum

Dimocarpus longan, commonly known as the longan (UK: /ˈlɒŋɡən/; US: /ˈlɑːŋɡən/, /ˈlɔːŋɡən/),

Logan must be a local variant. i just assumed it was a typo. Google redirects Logan to Longan. Certainly not a name I've come across anywhere else. And 'longan' is part of the binomial.

Longan trees are evergreen (never go dormant), which is why the leaves did not drop this winter. I highly recommend that you cut off the majority of the flowers/fruit, as this small tree still needs to put energy into growing bigger. I left half the fruit on one of my small Longan trees last year, and it almost killed it (still recovering). I have another Longan tree where I cut off all the flowers/fruit, and that tree is now twice as large and full as its sister. I am not an expert, but this has been my experience (also in SoCal).

Logan tree would confuse with Loganberry here, if referring to just the fruit.

Thank you all for your comments. I was worried someone might say that, to cut off the flower/fruits so the small tree can put the energy into growing bigger. Wow it almost killed your tree! Part of me don't really want to do that because I remembered reading on another forum, probably the tropical fruits forum, that it was difficult for many to get their Longan trees to flower or fruit. Maybe I'll post on the Tropical Fruits Forum. Will probably end up cutting the flowers/fruits though. BTW I do hate the spellchecker on my phone. Everytime I type "Longan" it corrects it to "Logan"

makojoe, I found an article on growing longan tree and at the bottom of the article someone posted a question about their 2 ft tall tree that is fruiting and the author, Marianne Cannon (garden expert?) said to leave it alone, that the tree will drop the fruit it cannot support. http://gardendrum.com/2014/04/11/growing-a-longan-tree/

There isn't that much flowers/fruit on my 3 ft tall tree but I will certainly keep a close eye on it. I still thank you very much for your advice. Where abouts in So Ca are you? I'm in the San Fernando valley. It's been close to 90 degrees this week, then raining on Sunday and Monday. Strange weather.
