What are some potential hazards to the growing hops?
Be sure the vines are adequetely spaced, congestion will lead to infestation and mildew problems. Wind is another potential hazard, try to reduce excessive wind shear. Over watering is also an issue, be sure there is proper drainage and be sure you water when there is draught. Some growers will make a mound around the vine to encourage drainage, rocks and gravel will help as well. Keep an eye on the growth and react quickly to anything that is suspect – mildew, insect holes and dryness are the biggest risk indicators.
