Purchased an Acerola Cherry tree.

Was doing great! When potting, I put about 2-3 inches of gravel on bottom of pot for drainage. Used Miracle Grow Organics hummus soil mixed with sand and cactus, palm, and citrus soil mix. Added 1TBSP of 10-10-10.

kept in 80% sun in its pot, kept in the front yard. Soil is kept moist.

Live in zone 7a-GA, and we did just recently have a night where temps dropped to high 30s.

Leaves appear dried out and curling, some light gray/browning, as in dried out or crispy. The rest are green and seem okay.

Did it get a little cold damage, too much sun, too much water?

Any advice would be appreciated. Thank you! Learning and would love to have success.
