This is what happened to my young Lilly Pilly after it was subjected to 4 days over 43 degrees in a row. Knowing Lilly Pilly’s resilience from past experience I was convinced it’d be ok and just kept it watered and covered through the rest of summer.
You guessed it, I was right and it’s now thriving!
It sure is a tough cookie and is loving life! Hopefully it’ll be more mature next summer and tough it out better (and hopefully I remember to cover it’s leaves in the hotter days).
