Thats amazing growth in 4 years!!!!!!!!! I am growing 2 Washingtonia Filifera's and one Washingtonia Robusta. Since this is my first winter with Washigtonia palms I have one Filifera in my greenhouse and the Robusta in my basement under a grow light. The other Filifera I have planted in the ground on the south side of my house (its about 6 feet tall now, and it was only 3 feet when I bought it in March). I have the truck wraped with pipe heat cables and I also have some soil heat cables under ground. I am going to put some christmas lights on the truck as well. I am also thinking about covering with a tarp of blanket on nights that get below 20 degrees.
How do you protect your Robusta in the Winter? How cold does it normally get in Little Rock?
