CHICAGO (WBBM NEWSRADIO) -- Warm weather that persists into fall may be good for us humans, but it may be confusing to plants.

Plants take their cues to switch into fall mode from the weather.  But, if warm temperatures persist into October and beyond, Chicago Botanic Garden Senior Horticulturalist Heather Sherwood said that may confuse plants into believing that it's spring.

"When we're staying in the upper 70's, that's not enough temperature range difference for the plants to really start kicking off and saying 'oh, it's fall time, time to shed some leaves a little bit,'" Sherwood said.

Warmer fall temperatures could also mean your grass will stay green later into the season.  Sherwood said we may have to rake and mow into December.

"It keeps us outside. It keeps us gardening and active. There's nothing wrong with a little more activities going into the holiday season," she said.
