Re: Trachy growth in 2020
My Trachy did really well this year. Maybe its best year ever. I chalk it up to my region having a Zone 8 winter followed by a summer and fall of no droughts. So, the palm went into the 2020 growing season with no dieback from the mass it put on in 2019. That was a huge factor. As soon as spring came, it was off to the races. In past years, July/August droughts could stop the Trachy in its tracks, but rainfall was consistent all year. Lawns never browned out.
Fate being what it is, I fully expect this coming winter to be cold enough to wipe out all those gains. I could, like some years, head into next spring with my Trachy having little green on it outside its spear. I'm just amazed that in 13 years of Delaware winters it's still ticking. In the 80s in Southeast Pennsylvania - about 20 miles north of here - winter exposure killed 2 of my Windmill Palms.
