Check these first
- Check the soil moisture by sticking your finger 2 inches deep.
- Inspect the drainage holes to ensure they are not blocked.
- Look for signs of standing water in the tray below the pot.
Likely causes
Overwatering
Most likelyHow to tell: The lower leaves turn yellow and feel soft or mushy to the touch. You might also notice the soil surface stays damp for more than a few days.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. Ensure your pot has drainage holes and never let the plant sit in a saucer of standing water.
Nutrient Deficiency
PossibleHow to tell: The leaves turn a pale yellow while the veins remain green. This often happens if the plant has been in the same pot for a long time without fresh soil.
What to do: Apply a balanced, water soluble fertilizer diluted to half strength once during the early spring. Avoid over fertilizing, as this plant prefers lean soil conditions.
