Hi - I am new to this forum. I live in Pittsburgh and we experienced unseasonably cool temps. While temps have been in 40s and will be through tonight (then will rebound). We had one night where temp dipped to 26°F.

Attached are some photos of leaf damage to my Japanese maple. My question - will the tree be able to recover? Any chance new leaves will come this year in place of damaged leaves? Should I fertilized now?

It may not be visible in photo, but the part of the tree closest to my home (where it was insulated) has many in damaged leaves. Only the front and top (exposed portions) were damaged.

Any thoughts would be appreciated. Thanks!

Your tree will be fine - losing leaves willl not harm it. Have you ever looked at bonsai JMs? The leaves are tiny to match the tree. That is accomplished by letting the tree leaf out then cutting all the leaves off. The growers continue to let the tree grow leaves and then they cut them off. They repeat until the tree grows the desired sized leaves (every succession of leaves is smaller).

No, don't fertilize. Fertilizer is not medicine.
