Check these first

  1. Feel the soil to see if it is soggy or bone dry.
  2. Check the drainage of the planting site.
  3. Look for signs of pests that might be draining the plant's energy.

Likely causes

  1. Improper watering

    Most likely

    How to tell: The leaves turn yellow and may feel soft or limp. This happens if the soil stays too wet for too long.

    What to do: Check the soil moisture before watering. Only water when the top inch of soil is dry, usually every 3 to 7 days.

  2. Nutrient deficiency

    Possible

    How to tell: The leaves turn yellow while the veins remain green, often starting on older foliage. This indicates a lack of magnesium, or of iron if it starts on new leaves.

    What to do: Apply a balanced fertilizer formulated for berries in early spring. Follow the package instructions for the correct amount.

When to worry

It is normal for the oldest leaves at the base of the plant to yellow and drop as the plant grows. Worry if the yellowing is widespread across new growth.

Stopping it coming back

Maintain a consistent watering schedule and ensure the soil has good drainage. Feed the plant annually to keep nutrient levels steady.
