All summer my Forsythia "
spring glory" would have new shoots and strong growth while other established growth would die back (turn brown, then dry rot).
I pruned out dead limbs as fast as they grew in and died which was almost biweekly.
Neighboring
plants show no signs of stress etc.
I do not use a sprinkler/watering system unless we go several days without rain. This summer we had ample rain.
New home construction landscaping.
plants approx 2yrs old, poor clay soil in a well drained location. Some organic amendments in root area. 1/2 day full sun or more.
zone 8 /
zone 7 borderline.
Any ideas ?
