Check these first

- Check the bottom of the pot to ensure water is draining freely.
- Smell the soil for any signs of decay.
Likely causes
Overwatering
Most likelyHow to tell: The leaves turn yellow or wilt even when the soil feels wet. You might notice a sour smell coming from the pot.
What to do: Stop watering immediately and let the top 2 inches of soil dry out. If the plant does not perk up in a few days, repot it into fresh, well draining soil and trim away any mushy, black roots.
Poor Drainage
PossibleHow to tell: Water pools on the surface of the soil for a long time after you water. The pot may lack holes or be sitting in a saucer full of standing water.
What to do: Ensure your pot has holes at the bottom to let excess water escape. Always empty the saucer under the pot within 30 minutes of watering so the roots do not sit in a puddle.

When to worry
If the stem base feels soft or mushy, the rot has likely spread too far to save the plant. It is normal for the oldest bottom leaves to yellow slightly as the plant grows.
Stopping it coming back
Only water when the top inch of soil feels dry to the touch. Use a potting mix that includes perlite to help air reach the roots.
