It's not quite fall yet, as the calendar flips to September. But you wouldn't know that judging by the color of some of the trees in Minnesota. If you think some of our trees have been turning color too early, you're right. Retired University of Minnesota Extension educator Julie Weisenhorn says that's not a good thing.

00:00Leaves already turning colors, and I think that is due to the drought.
00:04What's going on with our trees, and should we be worried about this?
00:07Yeah, so that's a great question.
00:10Leaves are turning already, and that's an indication of the drought
00:14and basically stress on the plants.
00:17So I happened to notice my neighbor's enormous old maple
00:22already starting to turn red, and right away I thought,
00:26oh my gosh, it's because it's stressed.
00:28At first I thought, oh, shoot, winter's coming,
00:31but then I realized, no, it's a stress.
00:34So that's true also if you see a lot of leaves falling right now.
00:41The trees are kind of shedding extra leaves so they don't have to support it
00:44because of the limited moisture and heat, too.
00:48It's hard because it's beautiful.
00:50You love to see the color, but then when you know it's for the wrong reason
00:53and it's too early, that's not good.
00:55Sometimes you'll see fairly small or medium-sized maples in particular
01:00along boulevards, and they're turning red in like July,
01:04and that's an indication of stress on that plant.
01:08Maples like cooler conditions.
01:10They like moist soil.
01:11They like organic soil.
01:12So we put them into our landscapes and urban sites,
01:15and it's not always the best place for them,
01:17but we do love our sugar maples in particular.
01:20We do love our sugar maples in particular.
