Outdoor pot temperature

8 posts in this topic

Hey everyone today record breaking temps here in southern Ontario 95 degrees. I have  8 potted palms outside. The pots are plastic. Question is. Those pots are blazing hot. My sabal palmetto had earthworms on top looking to cool off. Is there a temperature that will cook my palms that are in pots? Or is this just awesome and he roots will be loving this?

thanks everyone

They're good. Just make sure to water them as needed. I have many Alfies in pots outside along a southern facing cinder block wall and atop of cement(driveway). The readings are at 50C from both the wall and the ground.  They began to dry up from the tips. I thought it was sunburn.  But no. The water in the pots had evaporated.... I did the finger method in the pots. The soil was moist from above... however from beneath it was dry....

I'm watering the pots every two days. Their green color is returning.

Thank you. I have a moisture metre and it says that at the bottom I’m moist to wet since I just watered so I will keep on my usual and hope the palms enjoy the heat.

Be wary of employing a moisture meter in pots. Usually it will always produce a "moist/wet" reading. Especially if the medium is black.  For pots, nothing like the finger method. For planted palms, the meter is great. Jmho

Good call yes I understand. I sometimes use it for a quick check and yeah the fingers are the best. It can work against you it will read dry and the soil is soggy

What we have done when we worried about plastic pots getting too hot, was to put that pot into one exactly the same or any pot one size bigger. 

Even just adding the exact black plastic pot makes a big difference.

So far the crazy heat has been great. We are in a cool down now for a week but everything has fronds opening or spears growing very tall. What a great start for palm season here in south western Ontario Canada

Adonidias love heat, esp. humid heat as long as they get necessary rainfall or watering. Here they take 6 months in the 90s and an absolutely ferocious sun.
