Thanks for the advice. I put the garden lime on about three weeks ago now. The ph, as tested yesterday, is between 6 and 6.5. I’m just using a colour match swatch and indicator solution from a garden shop.A soil pH that low would have a lot of plants reeling! How long since you added the lime and how much?
Remember a big pH shift will set the plants back until they acclimatize.
Imagine yourself moving to Greenland, it'd be a while before you ventured outside without a huge coat
If you're lime addition was recent, chances are the pH will increase but then drop over time.
I think it's something like 300g of lime per sqm to up the soil pH 1 point but don't take my word on that.
Check multiple internet gardening sites to be sure.
You're looking for a final pH around 6 to 7
If you are still amending - aim for 6 because hops don't like alkalinity.
edit: I hope you are not relying on one of those cheap electronic testers, they are way off sometimes.
This one works very well and is easy to read.
It seems that the vines that came up before ph correction have been permanently stunted but new growth is going well now.
On the varieties that have new growth of pruned the old bines and the new ones are happy. But my Victoria hasn’t had any new growth yet, so it’s relying on only a small sprout for any sunlight. We’ll see how it goes.
