Likely causes
Insufficient Sunlight
Most likelyHow to tell: The leaves look pale or yellow and the plant seems to be stretching toward the light source.
What to do: Move your lotus to a spot that receives at least 6 hours of direct sun daily. If you are growing it indoors, you will need a high intensity grow light positioned directly above the plant.
Nutrient Deficiency
Most likelyHow to tell: Older leaves turn yellow while the plant stops producing new growth.
What to do: Apply a specialized aquatic plant fertilizer tablet into the soil near the roots. Follow the package instructions for the size of your container to avoid burning the plant.

When to worry
It is normal for the oldest, lowest leaves to yellow and die back as the season ends. Worry if the new, emerging leaves are yellowing or if the entire plant looks sickly.
Stopping it coming back
Keep your lotus in full sun and use aquatic fertilizer tablets every 3 to 4 weeks during the growing season.

Questions people ask
- Should I cut off the yellow leaves?
- Yes, you can trim them off at the base of the stem to keep the water clean. This helps the plant focus its energy on healthy new growth.
- Can tap water cause yellowing?
- Sometimes high chlorine levels in tap water can stress the plant. Let your water sit out for 24 hours before adding it to the container.
