I have to spray them with insecticidal soap at least once per week. The leaves on the bottom 5 feet of the zeus bine look horrible. Not sure if it was critters or what, but it seems to be doing fine now.
compost. twice a year, in spring and late summer before infloresence side dress with about 3-6 inches of good compost about 3 inches away from the bines themselves and then water well. depending on your climate you could probably also plant a green manure cover crop (like clover or alfalfa) in the fall and let it grow before chopping and dropping as mulch.
Since I planted mine in pots I used Miracle Grow potting mix that is timed release. Not sure its the correct amount but they are doing OK. I figured that would get me until August before I have to start adding something.
Nitrogen is the element they want during the vegetative growth stage. A balanced N-P-K fertilizer will suffice. There are many strategies to “fertilize”.
Too bad they are not putting more newsletters up. There is some more infromation on fertilzer there if you look those over. I do not have that good Midwestern topsoil. http://www.gorstvalleyhops.com/newsletter.php
Ok so I did a little investigating of my hops that weren’t growing. I pulled one out from the ground and found no signs of growth so I looked at the other two and same thing.
I got 3 bad rhizomes out of six one was a hallertau and the other two are cascade. I am a little disappointed. Would it be too late to try to plant some more?
