There's nothing on those to cut. They are very etiolated and light deprived and need all their foliage to recover. Get them out into the light outside in a sheltered spot until they are hardened off enough to go into the sun.

Is this normal, or did I do something wrong?

What exactly do you mean by "hardened off enough"? Are you talking about waiting for the new stalks to grow bark?

I assume the new stalks will die if taken into the sun now?

To be honest, they didn't need to be taken into your garage for the winter. They would have done just fine outside in the pots and you wouldn't be dealing with weak, light depraved sprouts right now.

Hardening off means that you take a tender plant and gradually expose it to outdoor conditions. If you put your plants in full sun right now you will burn the leaves. If you leave them in wind too long the leaves can dry out. So you need to acclimate them slowly.

Don't cut anything..

No, it's not normal. As Rodney explained, raspberries don't need to come inside in the winter. That's why you have that pale straggly growth. They were too warm so they tried to grow. But they didn't have enough light ergo pale thin stems. Take them outside for an hour or so then increase the time outdoors each day until they are out there all day and all night. The leaves will green up and the stems will become more robust. Don't cut anything off. They can't afford to lose any food making machines ie leaves.

Ok thank you everyone for the advice.

@ Floral, I just wanted be clear that the plants were in an "unheated" garage all winter in case this changes anything. I see that you had stated that the plants were "too warm".

They must still have been warmer than outside because the plants started trying to grow. If stored in a dark place they need to be completely dormant or they end up like yours have. This is a plant which can cope with, and indeed requires, low temperatures in its dormant state. Lower than the mid 40s.

Hey everyone. I had them on the porch for a week not in direct sunlight until they started looking better. I put them in the sun a few days ago all day and they look fully revived. Thanks everyone for your help.

Can someone please tell me how and when to fertilized? How often? I heard a 10-10-10?

Well done. Any chance of a new photo to encourage us?

Sorry I can't help with fertiliser question. I don't grow in containers and never fertilise anything.

Absolutely. I meant to take some. I will report back.

Here they are! Now that they seem to be on their way, one of my original questions was if I should prune the old cane. I have read that this is good to do. I assume it is the cane that is thickest with no green new leaves growing. When do you think is a good time to do this?

Those look much happier. The old cane is completely dead so it doesn't matter when you cut it out.
