Hello,

Please forgive my ignorance, but I have a question concerning the
health of potted Black Cherry (Prunus serotina) saplings, and I hope
someone here can help.

For years I have been potting these small saplings and they have done
quite well outdoors. This year I potted some and brought them inside
and placed them under a 1000 watt metal halide grow light. They budded
and began to leaf out, but now the small leaves are appearing to
crumple and discolor. I don't know what I am doing wrong, but I cannot
afford to have them die on me. I wanted to bring them in to get a jump
on the growing season. Can anyone suggest anything? Watering or
fertilizer regimen, different light, number of light hours?

Thank you all so much!!

MH lights are very hot. *THe young leaves may be getting burnt or

I have the light about 10" to 20" avove the tops of the trees at this
point. The recommended distance I believe is one to two feet, though
it does seem too close. However, I have an in-line fan running and I
do not believe that heat is the issue, as when I place my hand under
the light at just a few inches below it does not seem unusually hot.

I am trying so hard, but I cannot seem to find the answer. The soil I
used is potted top soil, and I think this should be fine. I have not
added fertilizer, only water about every two to three days.
