Hi Wsg89,

Considering you went to 6*F your pindo sounds like its in pretty good shape since it had only some leaf burn. You did really well if that is the only damage. Uncovered they are only good to 10-15*F generally, especially if planted less than a year ago. What is your general area and state.

Jim Hardy's did AMAZINGLY well for his zone 5 and artic air. He did use lights.

Any nights below 25 I would turn on lights, because they are PALM trees. Even if they can take it, why not give them better zone conditions, they will grow better come the Spring. Just make sure the lights are off and the palm is vented on temps over 30* becuase if the sun hits the mini greenhouse temps will go to high.

I am in Oklahoma City. I knew the pindo had to be taken care of with those temps. It has been in the ground 3 years, and it has not needed any extra treatment until this year It got 2 100 watt spots and a ceramic heater under a tarp inside the same portable greenhouse as the windmills...just a little too late!

Overall I think every palm will be just fine and even better this summer

Do you have pictures? Glad the palms are fairing well.

You have a really good planting zone for a pindo for several reasons, 1 its a little drier-they don't mind some dryness, 2 you are a solid zone 7 and not 6b(I would suggest protecting it every year if not zone 8), 3 this is your big advantage - your sun trajectory angle is STRONG even in winter, you are more cold by geography that Longitude -you are equivelent to North Africa or Mid California.

I agree. The sun is very warm here at this time. My little greenhouse can be 25 to 30 degrees warmer on a 20F day, if the sun is out. My Washy actually grows during the winter...
