Washingtonia Robusta in 3.6 gallon pot


Recommended Posts

So I guess my main question is; I have a Washingtonia robusta in a 3.6 gallon pot. I live in a temperate climate zone 6B as well. My tree is far from mature and I’m wondering what is the lowest temperature this palm should ever tolerate? I usually get the Washingtonia out on the deck when the weather is above 70 F (21.1 C) for that extra sunlight but the weather has been mild lately.  I’m wondering, since I have such a young tree,  is 55 F - 60 F is too cold?

55-60 too cold? Not at all! Even a young potted robusta should handle short freeze events without worry. For example, over winter I had about 50 single-leaf washy seedlings in red plastic cups sail through 2 or 3 different nights that dipped to freezing. Your larger plant and larger pot should handle that with ease. Maybe just bring it in any time temps may drop below 30?

Thank you for the advice. I will definitely be taking the palm inside once the weather drops too low. They seem so fragile at such a young age sometimes I don’t trust my knowledge lol. Thank you.
