There is nothing better than seeing trees flaunt fragrant flowers and green, glorious leaves in spring!
So, when will they sport their fresh new look?
While there’s no set date for all trees to break bud, we can use clues to predict when trees typically leaf out.
Find out when to expect spring tree sprout in your region and if you should be concerned about a late bloomer.
There are two ways trees know when trees wake up for spring. First, they respond to noticeably warmer days after a stretch of cold temperatures in winter. At the same time, they react to a change in light duration, when shorter nights and longer days of sun exposure, spur new growth and development.
At Davey, we use the Davey Nature Clock, a patent-pending software application that predicts bloom time and peak pest emergence. Utilizing weather data from over 400 locations across the nation, the Nature Clock helps to achieve more precise timing of pest management applications.
While the Davey Nature Clock’s predictions are specific for each year, species, and location, we can use it to generally predict when trees bloom.
Below learn when trees will typically leaf out and bloom in your area. And remember, if there’s unusual weather in your area, like a mild or severe winter, trees may bloom sooner or later than this.
If you’ve noticed trees around the neighborhood blooming while yours is barren, don’t panic! Just because spring is in full swing doesn’t mean your specific trees are ready to bloom or leaf out.
For example, some trees, like birch and willows, bloom early to lengthen their pre-summer food production time. On the other hand, trees, like oaks and elms, prolong their bud break to protect against sudden drops in spring temperatures early on.
As long as tree buds are green on the inside, they’re alive and well—just waiting for their time to sprout. If you don’t spot buds or the buds are shriveled or black, that could indicate it's a problem.
