I have 2 conifers about 20 feet apart with patches of their needles
turning red. One is a weeping bald cypress, the other is a dwarf
alberta spruce. I see no sign of insects. I have sprayed them with a
3 in 1 product called Safer, but the areas continue to spread. Are
these trees goners? Thanks in advance.


Are they receiving enough water? It would help to know the age of the
trees and where they're located.


I live in Northern Va. zone 7. They are both about 5 years old. They
are in full sun. They may not be getting enough water. I only
water them if we don't have any rain. Thanks.


They're very young trees, probably not planted too very long ago.
During dry spells they need to be watered deeply once each week... do
not sprinkle them every day... just one good deep watering each
week... could probably benefit from a good layer of pine bark mulch,
just don't let any mulch touch the tree trunk.


Thank you, Sheldon. I'm glad that the problem is not a disease. I
will start to properly water them. Since the bald cypress is
deciduous, it can start fresh with new needles next year, but the
spruce...will new growth (albeit slow) eventually fill in and cover
the affected areas?
