Cascade Hops problems — and how to fix them
Cascade Hops (Humulus lupulus 'Cascade') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Downy and powdery mildew
Humid, crowded conditions cause yellowing leaves, distorted shoots and discoloured cones. Improve airflow, strip the lowest 60-90 cm of foliage, water at the base and remove infected growth promptly.
Spider mites and aphids
Hot, dry spells bring spider mite stippling and aphid colonies on leaf undersides. Hose off, encourage predators, and treat heavy outbreaks with insecticidal soap or a miticide.
Weak first-year yield
A newly planted rhizome puts energy into roots, so cones are sparse the first year. This is normal; vigour and yield climb sharply in years two and three.
Bine collapse without support
Fast, heavy bines need a sturdy 4-6 m trellis or string from the outset. Train 2-3 strongest shoots clockwise up the support early; unsupported bines tangle and rot on the ground.
