jwf1983 Posted July 22, 2021 Report Share Posted July 22, 2021 I have two Trachycarpus Fortunei outside on our Washington, DC patio. They remain outside year round. Early on, I was convinced that winter extremes would test the hardiness of these two, but after a couple of years I've noticed more sensitivity to extreme heat than anything else. Both are in large pots and are about 3 feet high with fronds spreading about 4 feet wide. They get a good 6 hours of direct and indirect sunlight, with some obstruction of light due to a Sago alongside and in front of the Trachy). By mid July, despite watering every other day or as it appears to be needed the tips of the lower fronds appear slightly green/brown, with some of them appearing folded. Closer to the top and the spear, new bright green fronds continue to grow and these appear to be entirely open (not folded). I realize that some of the lower fronds not appearing as vibrant as the newer ones is probably normal, however I have noticed that if temperatures are consistently in the mid 90's for any stretch longer than a few days, this frond folding/darkening becomes much more pronounced. Recently, we've had a break in the normal summer heat, with temps in the mid 80's during the day. I've noticed the fronds appear to be regaining some color and expanding once again--at least a little. Does anyone have any observations or insight into Trachycarpus Fortunei having issues with extreme heat, or a lack of tolerance over certain high temperatures over an extended period of time? I realize there are parts of the world more consistently hot than here in the summers, so I wonder if anyone has noticed similar issues, particularly when potted. Also worth noting, that the fronds appear to be much brighter in the late spring/early fall than in the middle of the summertime. 1 Link to comment Share on other sites More sharing options...
