Oak Tree Trimming

Asked August 23, 2018, 3:24 PM EDT

I have three Pin Oaks that have been planted for several years now. They are between 11-20 feet or more. I can not mow under them with the mower the branches hang way to low. I would like to be able to mow under them, can I trim off the bottom branches? How will this affect the future growth of the tree?

Hello, You can absolutely prune pin oaks. The trick is trimming branches with a clean cut as close to trunk as possible. The best time to prune oak trees is during the dormant season (November through February). Pruning during the “dormant” season avoids potential complications with the fungus oak wilt. For proper pruning methods, please review the following publications: http://www.na.fs.fed.us/spfo/pubs/howtos/ht_prune/prun001.htm http://www.ces.purdue.edu/extmedia/FNR/FNR-215.pdf http://www.ext.vt.edu/pubs/nursery/430-455/430-455.html If you are not comfortable pruning these trees yourself, then please contact a local certified arborist (check yellow pages). Best of luck.
