How many days does it take for trees to grow their leaves back after winter?

The time it takes for trees to grow their leaves back after winter varies by species and climate conditions but generally occurs in spring. In temperate regions, many deciduous trees begin to bud and produce new leaves within a few weeks to a couple of months after the last frost. Factors such as temperature, sunlight, and moisture levels can significantly influence this process. Typically, you can expect to see new leaves emerging anywhere from late March to early May.
