I need a diagnosis. These pics are of my first year hops. They are all being grown in containers in Miracle grow potting soil. I am keeping them watered and check the moisture every other day to ensure that the soil is moist. I am using the Miracle Grow powered plant food ( 2 scoops to 2 gal of water) for the 6 plants. I do this every other week. I thought I might have some spider mites so I made a solution with Ivory Soap and water and sprayed the leaves. I started pruning off the bad looking leaves as the top bines are starting to look like they are producing cones.

I really could use some help.

Looks like Fert Burn to me, quit fertilizing them for a while. Mix that Miracle Grow at 1/4 the recommended strength to keep this from happening anymore. I only fertilize every 2 weeks, if I remember...

Will do. Thanks for the quick reply. Should I continue to prune the leaves or can I just leave them?

Yep, no problem. If the leaves are still green then they are photosynthesizing so you can "leave" them be. If they are brown/yellow and don't have much green left on them then pluck them, they aren't doing anything for you at that point.

Usually in soils that have been overplanted--but iron defiency looks like that yellow color.
Miracle Grow is NPK and not so many micro nutrients.

Iron is essential for formation of chlorophyll. Sources of iron are the soil, iron sulfate, or iron chelate.

With fertilizer burn and corking.

I think it is too little iron that makes the plant unable to process too much nitrogen.

Plus what are you thinking raising a poor little hop plant in Five Points?!!!

What do I need to do to increase the iron? Should I just water and RDWHAHB? Five Points is not the Five Points of old. In addition to the hop garden we have a community garden that no one has messed with or picked from. I guess I have excess good karma credits. Here is my ghetto fab hop garden

I also have a layer of mulch covering the soil. Could that be stealing nitrogen? Should I remove it?

Mulch is good for moderating soil temperature which is crucial right now --98 degrees
yes decomposing mulch binds up the nitrates and makes then unavailable for your plants but we were talking about too much nitrogen. So I vote yeah for mulch!

We use Ironite, shameless plug now:
A natural fertilizer and soil supplement that provides, in a single application, an effective blend of nitrogen and other essential nutrients to stimulate growth, color, and promote maximum root depth. Replaces vital trace elements, slow-release, and will not burn. Neutralizes alkaline soils, contains natural soluble iron, and can be used on shrubs, trees, flowers, and lawns.

That part about slow release is crucial. We lose the benefit of iron out here because water can wash it away in our alkaline soils Most of all in the future get those hops in some honest to god real life dirt!

Colfax isn't the same either. Next time in Denver maybe we will drive by

Montrose's redneck hop yard

PS Wait little old ladies at the church for our community garden rip us off blind when something ripens. Goes to show.....
