Re: Palmetto root temp
Edited by Jim Wilmington DE 7a on 6/18/2018, 12:22 pm
My palmetto's growth this year has so far been almost non-existent. Same with my minors. They are otherwise healthy. My Trachy is growing very well, as are my needles. So, the no/slow growth is limited to the Sabal genus. I wonder if it's due to soil/root temps. Summer hasn't really been hot yet (until today). So, I'm thinking that the soil is cooler this year compared to most Junes at this time.
Tommy, couldn't you use warm water?
