Why Are My Raspberry Bush Leaves Turning Yellow?

Question

I’m looking for recommendations or advice on treating my new raspberry shortcake bushes. They were nice and green when I brought them home and now the leaves are turning yellow and dying off. It is only happening on the old canes and they are still producing fruit beautifully. I suspect I was overwatering them so we have completely cut back watering to once a week. They are in containers and not the ground yet so I’m assuming they need to be watered more frequently then established plants. Should I leave the yellowing and dying leaves or remove them? Add nutrients to the soil? I have five bushes and it is happening to all of them. Help!

Yes, I do see signs of overwatering.

Instead of watering on schedule, try watering when the container needs it. Once the soil dries down to about 3 or 4 inches, give it a nice deep watering. This take will vary depending on the climate conditions at the time, so measuring is important. Just stick your finger down to the depth of 3 or 4 inches and if there is any moisture at all... Hold back on watering. Alternatively, you can get a moisture meter to help.

Treat with a fungicide, then care for them as usual.
