Are my Queen Palms dead?
New to Palm talk, so please excuse me if this is a redundant topic. I live on the North side of Houston TX - and have, or had, seven queen palms in the 8-10 ft range that were in the ground in my yard for 3 full years. In Jan 2017, we had a hard freeze, around 19 degrees, that lingered well into the next day. All the queen palms took it very hard, with all losing all their fronds over 1-2 months. I waited a couple of months, and saw nothing positive happening even though we had an extraordinarily warm Feb - in the upper 80's. I'd read about stumping, cutting off a foot or so until you didn't see any rot. I cut three - still about 8' tall - on two I saw cores in the middle of the trunk, while one looked like the cross section of any tree, with no cores obvious. The two with cores had the cores pop up a few inches the first day, and now, three weeks later , have maybe 18" growth and are starting to spread into fronds. The trunk without visible separate cores is doing nothing. I cut the remaining 4 about 10 days ago - all showed clear cores. That day, two of the fresh cut trunks showed core growth pop up a few inches, and they already 10-15" tall and look like they are about to start spreading fronds.
My question is this - I have two trunks that had visible cores and one with no visible cores that are just standing there - the trunks are green, and very solid - no sign of rot or that they are dead - but no sign of any growth - so are they dead? Is there anything I can do to encourage growth? How long should I wait before I declare them dead?
Any advice would be greatly appreciated.
Thanks again - mark
What temp to bring indoors potted Trachycarpus fortunei
For a potted Trachy in a large plastic 28" pot (double wall with 1" air pocket), around 1.5 feet of trunk what temp would you bring it indoors to prevent roots from damage?
European winter 2016/2017
By Exotic Life
What will this winter bring in Europe this time?
Please post what is happening over at your place this winter.
The last few winters were really mild for us here in northern Europe, so hard to get even milder winters.
Winter 2013/2014 was even frostfree for me, last two winters had some frosty moments but mostly around -1C for a few hours exept, beside a few nights which were colder.
This november has been quite average and had some frost as well, last weekend I recorded -3 and -4 and also this weekend looks a bit frosty. Long term is evolving again to a mild episode with temperatures in the double figures, it is however impossible to beat the last year mediterrean look a like winter.
Climate Standard Deviation
I think the standard deviation of a climate is an important consideration when analyzing its' characteristics. I've never seen anyone directly mention standard deviation as a factor but I think we all know the potential implications, not all zones of the same type/number are created equal.
Consider Brownsville Texas, a zone 10a, similar to much of central coastal Florida right? But the all time record low in Brownsville is a whopping 12* F! That's 8a, two full zones lower than average, if you were to actually plot out all the lows I image in you would get a wide deviation in general. On the opposite end of the spectrum, consider Key West Florida, a zone 11b. The all time record low is 41*F, only 1/2 zone lower than the average yearly low.
I would love to see some work done on this, along with the USDA number, also see some kind of quantification of the standard deviation, it might make it easier to estimate just how much chance your favorite Palm might have. Not all zones of the same number are created equal, this would be a good metric to differentiate them a little more.
