How long does it take for trees to leaf out in the spring?

Answer 1

Individual trees can leaf out very quickly. You can hear it happening on a quiet night. But different varieties leaf out at different times. Norway maples are very early and you might think a sycamore is dead because it leafs out so late.

Answer 2

Depends on the tree, the vegetation or whatever. They do it at different rates and time. Takes about a month for my maples to first start showing signs of their blossoms until they are totally leafed out. My grape vines on the other hand, take things much slower.

Answer 3

I'm certainly no botanist but from my experience once the trees start to bud it happens fairly quickly especially when its sunny and warm. Cool and rainy days will delay them a little bit but by the end of May most are in their summer form, at least in southern lower Michigan. 

Answer 4

about a week or so

Answer 5

It depends on the soil temperature. Once it warms up enough, they start to leaf out.
