Should I cut off the yellow leaves?

Yes, you can snip them off with clean scissors. This keeps the plant looking tidy and helps you spot new yellowing more easily.

Can fertilizer cause yellow leaves?

Too much fertilizer can burn the roots and cause yellowing. Use a balanced liquid fertilizer at half strength once a month during the growing season.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow and feel soft or mushy. The soil stays soggy for days after watering.
What to do: Allow the top inch of soil to dry slightly before watering again. Ensure your pot has drainage holes so excess water can escape.
Underwatering
Possible
How to tell: The leaves turn yellow starting from the edges and feel crispy. The soil pulls away from the sides of the pot.
What to do: Water the plant thoroughly until moisture runs out the bottom of the pot. Stick to a schedule of watering every 3 to 7 days to keep the soil consistently moist.
