Hello cyumickey, Judging by the age you say the tree is, I wouldn't do too much cutting yet. As Bahia said, don't let branches grow from the ground or around the base of the tree, these branches will just cause you trouble in the longrun. Also, don't let branches grow onto the ground, and cut out any branches that are crossing other branches, saving the branches that most help with the general shape of the tree. Any other cutting on branches after all that cutting should be saved for general shaping of the tree...if at all (like I said, I think the tree is a bit young still). As for when to cut back a citrus tree, anytime but winter is usually fine. Finally, don't fret about not getting fruit yet. The trees are coming to age soon though, and if you can get a regular soil amendment schedule going, all the better. My two cents, Ken

I would leave the tree alone for now to see if any green shows up later. Is this a grafted tree and do the sprouts look like they are coming from below the graft? Andi

Yes,you're correct, jkom51. I probably should have been more clear: mature in-ground trees will eventually need some pruning, but mostly to remove any heavy inner canopy branches (the branches will eventually die, if buried in the canopy), and any crossing branches, but beyond that, and the occasional water sprout that might need to be trimmed back, citrus really should not be pruned in the same way you would prune other trees. If you have a tree that is becoming monstrously tall (standard rootstock grapefruits and pummelos can get pretty tall), you can drop crotch prune them to bring them down in height. Or of course, next time buy a tree on semi-dwarfing rootstock. :-) Mature container citrus may also need some minor pruning, and even root pruning if you're trying to keep the tree small, so it will fit in a reasonably sized container, but a young container tree really shouldn't be pruned, except perhaps the odd water sprout.

For reference have seen LED articles reference 10,000 Lumen per square ft as a benchmark for the sun. A 100,000 light will light an area 1'x10' one foot off the canopy. As soon as you double the distance you only have 50,000 lumen for plants and double it again you have 25,000. High Lumen and close to the canopy are important features to look for. There are 3 points of heat; the LED chips, the digital driver, and either a fan or passive cooling.
