One of my best hop plants, a 4 Year Old Centennial bine, is sick. This plant lives in a flower bed and climbs up a railing. Most of my plants grow but I've struggled with problems over the years. Spider mites are a battle I've mostly won. I don't think the soil composition is that great, but my plants are bigger and healthier each year. The hops themselves have not been great, rather weak in bitterness and rather grassy/oniony.
This spring, I've neglected the plants somewhat. I've pruned them rather heavily, including a big clean up last weekend, followed by a miracle gro feeding. But, this particular Centennial is not doing well. I don't know if the plant is just stressed, has a nutrient deficiency, or a disease. I can say that insects do not seem to be a problem for me this year on any plant so far.
Symptoms:
- Older leaves show some downcurling and brown/yellow spots.
- New side branches have been stunted, with tight but underdeveloped leaves.
- Some of the small flowers ("spikes?" What are those things called?) have regressed and are looking like small grey buds.
Our weather has been pretty extreme, with periods of 90+F days followed by tons of rain, wind and 70F weather.
What do you think the problem is? Looks like it could be verticillium wilt?
