When To Tap Maple Trees 2025. Generally, a maple tree should be at least 10 to 12 inches in diameter to ensure a healthy and sustainable tapping process. My plan was to possibly have taps in either february 10 or 17 this year depending on the weather.

There are some here that have been tapping the same trees for generations. If you follow good tapping guidelines you should be able to use the same trees every year.
