cedrus brown leaf tips

Post  jferrier on Mon Feb 14, 2011 9:11 pm

I have a deodar cedar that was brought inside the house for a few days during a very hard freeze. I put it back outside during the day after temps got into the 40's again and it spent the night outside in the lower 30's without much wind and another night in the 40's. Then almost overnight, the tips of almost all the needles are brown w/ the worst ones being on the crown. I have it planted in a well draining mix and have only been watering the soil when its dry. Anyone have any ideas as to what may be the problem?

How long have you had it?

Those temps (and probably the freeze) would not have hurt it.

I bought this tree in Dec 2010 from a mom and pop landscape nursery. The tree has about a 2.5 to 3" dia. base and is about 18" tall. Roots appeared to be in good shape with new white tips when repotted. Some fine roots just at the top had dried where soil had washed out of the container while at the nursery. I Did a heavy pruning then and repotted in slightly larger container with about a 75% grit and 25% soil/mulch mix. I did no root pruning. The tree has been outside all winter and only put into an unheated metal shed at night when there were high winds. I am in Fort Worth, TX and as the saying around here goes “if you don’t like the weather, wait a week.” The temps this winter had been mild with only a few nights in the lower 30’s and maybe 2 days of light frost. Avg. temps have been in the 40’s to 60’s with a few days reaching nearly 70 before the freeze. So bringing it inside wasn’t really much of a change since my house stays in the mid 60’s. I brought it in the night before the freeze as temps were in the mid 40’s and dropped to about 13 by mid morning. I put it back out 3 days later at about the same temp (40's). Here we are a week later and we are back in the 70’s again. I did read that drying out or winter burn usually occurs on the top and outermost limbs and this is the case here. So I’m hoping it just got too dry inside since I’ve been keeping it on the dry side anyways to avoid winter waterlog. The buds still look ok so I think it will survive. On a side note all my Japanese Black pine seedlings and several of my pinyon pines that did not come in have suffered severe needle damage and I'm afraid most of the Black pines won't survive.
