I've noticed that when my hops begin to bud that the leaves always seem to suffer a little. The ends dry up and they don't look very healthy. Is this normal? has anyone else noticed this or do I have a problem. I live in the Chicago area and it gets pretty hot in the summer. The variety is Mt. Hood and I've been growing them for about 4 years and it's always the same. Strong healthy leaves in the spring and half dried up leaves by mid June.
