| I planted several Dawn Redwoods a few years back and they seem to be doing fine although the extreme warmth we had last March followed by cold weather took a toll. Can I expect a full recovery this spring? Also if we continue to have unusual weather conditions into 2013 can these trees take it? |

| its a conifer .. and also a tree ... i had no problems down here in adrian MI .. beyond that.. you dont give us much info beyond generalizations ... so as to give you specific advise.. so generally speaking .. sure.. they should recover ... and w/o a definition of unusual.. i can not predict ... they have been around since the dinosaurs ... so one might presume.. that they should be able to cope with just about anything ... the only thing that worries me.. is how they were planted.. and if that is having any impact ... how old are they.. how big.. potted stock?? .. whats your soil.. how have you kept them watered... are they in full sun ... did they bud out in march with that week of 80's.. only to be deleafed with the repeated frosts and freezes thru june ... etc ken |

| If my Dawn Redwood had 10 hit points worth of life then last summer's drought probably used up 5 of them! Seriously, it defoliated 90% and then had time yo grow back some foliage. What gives me hope is it seems to have set the usual number of buds. I worry about if it woukd live through three dust bowl like summers if we are in a repeat of the 1930's climate cycle. Up north though how bad could yours have been? Being of the same genetic stock if mine can tolerate st louis heat it should shrug off northen heat. I would think your cold spring snaps woukd be more threatening. |

| Dawn redwoods have survived like 200 million years. If the tree wasnt stressed before hand, Im pretty sure it should come back. Ive read they are hardy to about -30C (roughly zone 5 or a warm 4). I have heard of people growing them in Toronto and the surrounding area... |

| Mine in Z4 are decidedly less impressive than the pictures I see of some members' here in Z5 and up. I only ever had 3 of them up there, the best-looking 1 of the 3 up and never leafed out a couple yrs. back, and the 2 remaining while still alive, just don't have that zing. But, they do continue to survive and who knows, some day they may be great. +oM |

| Well, you need to tell us what you mean by "took a toll". We can't help you at all without a better description of the problem. |

| They are very forgiving trees. I pruned about 90 % of mine about 7 years ago because it had crossing branches and bad form. I thought maybe I had overdone it with the pruning. It came back with a vengeance, no stress whatsoever. It still has bad form, not common for the species, but I let it grow however it wants. I started it on a window ledge. It was one of those "Tree in a box" trees. Maybe the branching pattern was messed up by lack of overhead sun, being started out on a north faceing window sill. Ok, whatever, they are hard to kill trees. |

| My three were planted 8 years ago (the tallest is close to 30 feet now) and came through last summer's sustained heat and drought just fine without any extra attention from me (it probably helped that we had another minimal Japanese beetle season). They are tough trees and in my experience only need a little coddling when they're small saplings. |

| Poaky, I think the species just grows like that. Maybe some of the improved varieties don't have that dense crazy branching pattern, but most of the ones I see do grow crossed branches as a small tree. I think the adult from is looser. The one here has enough branches growing back towards the trunk that I assumed it was eventually going to be run through, but that hasn't happened yet. Tree is about 15ft tall. |

| Seems like all the big botanical garden ones I've seen have decently straight branching structure. The MOBOT trees I see alot and I've noticed pruning cuts on them. Don't know if they are structural or if the lower branches just quit producing as they get shaddd out. So far I pruned one branch on mine. It was crossways and rubbing badly as well as being located an inch from another on the trunk. On the north side of my tree I see one branch w/o any buds on it. Figure that one is on schedule to be removed soon. It is a crosser also. |

| I have three out of six that had branches die from being shaded out. I was surprised how little shade it took for those branches to die. The branches were being left for the 'armpit' effect. Mike |
