Frost damage I assume?

Nothing like you all up north have had but we got to about freezing last night after a record warm March.

Oxydendrum arboretum Sourwood. (I spelled that wrong!)

Nyssa sylvatica

Malus crabapple, did the fruits get zapped?

None of this appears very bad at all. Do I need to concern myself with "future" damage from this frost?

I know Nyssa is very sensitive to frost.

None of my plants suffered damage at 28 or above.

It was that last mystery temp between 21 and 28 that zapped them.

Good news is that "most" deciduous trees bounce back.

you know it frosted

you observed it frosted...

you diagnosed the frost ...

how in the world do you jump to disease ...

open your mind.. put the chemicals in a small room in your head .. shut that door.. and move on ..

crimminey .. you are worse than a dotting parent.. lol ..

give a month or two .. then make some further observation .. dad???? [its hard to type the inflection of a 14 year old daughter.. lol]

Hmm... I reread the OP after Ken's post and can't find mention of disease???

Anyways, most of your trees should bounce right back. I had a late freeze last year that killed quite a bit of new growth on many new transplants and they made it through fine. About a week or two after the leaves turned black, new growth emerged at the base of the dead stuff. Just walk into the house with blinders for a couple of weeks and you won't even notice anything went wrong by May :) (other than a fruitless crabapple ;))

Forgot to mention-

Yes, sometimes the damage is not apparent for a week or so then a couple small immature leaves that looked fine the day after might get black spots and begin to shrivel.

Yeah, maybe I should have said I've never noticed frost damage to live tree foliage before.

It was interesting hiw on the four foot Oxydendrum the damage was only on the branch down at shin height. The crabapple fruit is actually the highest damage elevation wise.

RE: Frost damage I assume?

one of the glories of moving out of suburbia.. into the country.. is that i actually own a hilly property ...

you would simply be amazed.. how .. over 500 feet across.. a 10 foot depression can cause bizarre frost patterns ..

get this.. gravity causes cold heavy air to fall .. and it moves over unflat ground.. go figure.. lol ..

so i can have one plant decimated.. next to plants with no damage ..

high damage here.. low damage there.. etc ...

no damage on the hill facing south ... etc ...

mother nature is truly bizarre.. and anyone.. who thinks they can predict her vagaries.. is truly.. and completely ... delusional ...
