Amidst all of the snow everywhere and the freezing temperatures, yes, even still here in The Deep South, my Meyer lemon tree is in heavy bloom. It is really more like a shrub than a tree - and a leggy shrub at that - because it is in a planter. I want to say that it is going into its third year of growth for me.
Meyer lemon trees do not like low temperatures, and will, in fact, go dormant at 54 degrees, so I move mine in and out of the house anytime the temperatures are cold. Needless to say I have been moving it in and out alot here lately, and it has paid me off with early blooms. In fact, this is the most I've seen it bloom since I purchased it, though last year it also had a lot, maybe half of this, but they simply dropped off and did not produce fruit, or if they produced fruit, many just fell off right away. I'm thinking that it was likely a pollination issue, so I've already broken out a paintbrush to move these blooms along, since there won't be any bees around for awhile yet, and certainly not inside!
You can fill a thimble with what I know about Meyer lemon trees, so I have no idea what might have happened last year, but I do hope that with this nice start, I might actually have a few pretty lemons to show off to you later this year! For now, I am enjoying the unique perfume of these pretty, delicate blooms.
