When Do Tree Leaves Come Back in Spring

when do tree leaves come back

Around our area, the earliest blooming/leafing trees typically begin to leaf out around mid to late March, according to the USA National Phenology Network. Spring 2020; however, has brought early spring weather causing trees and shrubs to leaf out and bloom on average 24 days earlier than normal.

How Do Trees Know When To Bloom/Leaf Out?

Trees decide to leaf out and wake up from their dormant state based on a combination of signals including the weather becoming warmer, the days getting longer/increase in the amount of sunlight, the soil becoming warmer, and nutrients & water becoming more available. This combination of signals triggers an internal change that prompts the tree/shrub to grow new leaves and take advantage of the favorable growing conditions.

My Neighbor’s Trees Are Leafing Out But Mine Aren’t. Should I Worry?

No, there are a lot of aspects that go into the timing of trees blooming and leafing out. Your neighbor’s tree could be getting more sunlight which can cause it to bloom/sprout faster or could even be a tree species that blooms earlier in the season.

Early Blooming/Sprouting Tree Species:

  • Birch
  • Willow
  • Cherry
  • Eastern Redbud
  • Alder
  • Lilac
  • Maple
  • Buckeye

Late Blooming/Sprouting Tree Species:

  • Oak
  • Elm
  • Hickory
  • Walnut
  • Ash
  • Mulberry
  • Sassafras

As long as your tree has buds and they are green on the inside, they are alive and will sprout/bloom when they are ready. If your tree doesn’t show any buds by the time spring is in full swing, it could be an indication of a problem.
