Check these first

  1. Feel the soil to see if it is soggy or waterlogged.
  2. Check the drainage of the planting site after a heavy rain.
  3. Inspect the base of the canes for any signs of decay.

Likely causes

  1. Poor Soil Drainage

    Most likely

    How to tell: The leaves turn yellow and wilt even when the soil feels wet. The roots will look mushy and dark rather than firm and white.

    What to do: Amend your soil with organic matter like compost to improve drainage. If the area stays swampy, consider transplanting the raspberry to a raised bed.

  2. Overwatering

    Possible

    How to tell: The soil surface remains constantly saturated for days. The plant shows signs of stress despite frequent watering.

    What to do: Allow the top 2 inches of soil to dry out before watering again. Stick your finger into the soil to check moisture levels before adding more water.

When to worry

If the canes are turning black and brittle at the base, the rot may be too advanced to reverse. Minor yellowing can often be corrected by adjusting your watering habits.

Stopping it coming back

Ensure your soil is loose and well draining before planting. Never let the roots sit in standing water.
