I’ve recently planted raspberries in the ground here and ive run into issues where the leaves are turning purple between the ribs and the margins of some are wilting. I know I have slightly more neutral pH of around 7 - 6.5 so perhaps that an issue, it is also clay soil but not super heavy. Any ideas of what I could try? Ive put down some dried chicken manure to help, but I home I’m not over-fertilizing.

Has it been cold (low 50s?) and very wet? Purple can be phosphorus deficiency, but also will just happen because of the cold.

To second that, mine looked like that before it warmed.

Ah thats true it has been, youre probably right about that. I doubt its a phosphorus deficiency as i’ve fertilized it well. However the leaf curl and some canes wilting are what is more concerning to me
Mine looked like your first and second picture when the temps were fluctuating pretty low.
I noticed berries forming on the plant with very wilted leaves; I highly recommend cutting off any berries and flowers the newly planted canes try to produce this year. I lost two newly planted, very vigorous raspberry plants last year because I didn’t stay on top of the blooming, and they burned themselves out.
I wish I could help you better than that, sorry.

It has been quite cold recently in PA, lows in the 40s and highs in the 50s so thats probably it. This is the plants second year so it might be ok without pruning. I had it in a container last year. The other raspberry plants I have are just a little purple so I’ll just be patient and see.
I bet just giving it time, especially when it warms up, will solve a lot of these issues

I hope you’re right. Fresh raspberries are delicious!

The red looks temperature related. There does seem to be some signs of potassium deficiency on some of the leaves. Chicken manure is not the best for cane fruits that hate hot nitrogen. A bit of Langbeinite in mid-late Summer whould fix any potassium issues.
Brambles tend to hate hot nutrients, so they are perfect candidate for organic nutrients that tend to release slowly.
Avoid nutrients with chicken manure or seabird guano-they tend to be hot. I don’t know why one bird makes manure and the other guano; perhaps it is one of life’s great mysteries.
One animal is domesticated and the other is wild? IDK, just a guess.
What about well composted chicken manure? I have chickens and use the deep litter method, so there’s always year-old stuff when I clean out the coop (I’ll be doing it next week). I was planning to give some of the good stuff to my blueberry, blackberries, and raspberries.
Well-composted chicken manure is a lot better, but you still want to be careful that you don’t feed too much nitrogen. Blueberries like more nitrogen than cane berries. I prefer Black Cow compost and worm castings.
