I am with you on change. Since I am going away for awhile soon, my wife has forbade me to replace anything that dies from the cold between now and then. Having enough other hobbies, I am ok with this...for now. When I get back though I will be replacing anything that dies with cooler weather trees since from what I have been reading, this is not a freak cold winter but the start of a cooling trend for the next 20 or so years because of sun activity similar to the last mini-ice age back in the 17-1800s. What I will be doing is adding trees that don't care.
Think of building up a collection of exotic loquats, maybe a new persimmon and apple varieties or two(already been adding crab apples who probably love this weather). For several years now I have been removing citrus as it dies so no big loss there. I might look into some of the berries that they have a zone or two north of us too. I have a year to research it all and wont be in a rush even then since I wouldn't be able to get cool stuff until spring anyway. Note I am not pulling up my trees, just replacing the ones that don't make it due to cold or whatever.
the climate looks to be changing radically.
summers here have been hotter (i data graphed 50 years)
,but the couple of cold frost a year we get seem to be colder. some parts of the country are drier etc...
the first 3 years i started growing fruit trees we didnt have a freeze, or , maybe 1 that just hit 32F.
i had 3yr papaya 20ft tall.
now, every year they freeze almost to the ground.
i have several Jujube, and even an Indian juju seedling about 3ft that didnt seem too bothered by the 28F last week.
i have several mulberry, pomegranate, fig, feijoa, longan
acerola usually dies to the trunk, but comes back to fruit every year.
i may get some cold-hardy Kiwi next
