...and even set a few peaches. This is an early variety, 6-7 y/o tree, typically a great producer. Foliage was becoming less and less through Aug (normal), then in mid-Sep quite a bit of new foliage, followed by a maybe 35-40% bloom rate (compared to spring). Now there are a few grape-size peaches, with the potential for more. What gives? So much for "chilling hours" requirement. B-CS area.
One Methley plum tree also has a few blooms, but I have seen that happen before.

I'd pull them off. You don't want the tree eating up energy it's going to need during the winter. Or have it going full bore if a heavy frost hits out of the blue.

Interesting. I have two crepe myrtles putting on new leaves.

Noticed my meyer lemon blooming last week. Need a cold front.

Saw a red bud tree bloom 3 weeks ago, kinds weird

Sounds like you might have peach pie with fresh peaches when the Mayan Calendar ends!

My crepe myrtles and roses are blooming as well.

My peach bloomed as well. My lemon trees are also going nuts.

I have quite a few bluebonnets popping up all over our place. And a lot of other plants putting out new growth and setting blooms where usually you'd think they'd be starting to shut it down for the winter.

Seems like the weather conditions that last 2 years have got them confused. Loooong, severe drought of 2010/2011 followed by a relatively wet fall of 2011 and spring of 2012, along with a very mild winter and average summer. I guess they've been through really tough conditions and they see the good weather continuing so they're growing and trying to reproduce while they can.
