Is this yellowing normal for a kalanchoe plant?

Question

This is the only yellow leaf and the plant is even sprouting out 4 new shoots. I keep the soil moist and let it dry then water again. I don't keep it in direct light. It's in a breeze way that's probably... 80 or so degrees. I'm in Texas where it's 100 outside.

Answer 1

That leaf is on it's way out. Plants discard leaves for various reasons:

• overwatering: older leaves are discarded while still plump with water, usually seen with yellowing and sometimes the spotting from virus/fungus/bacteria
• underwatering: leaves wither and die from the tip back. They are dry and papery.
• leaves accumulate waste products as they age and older leaves are discarded when they are no longer efficient

Remove this leaf cleanly at the stem and watch for more symptoms. If more older leaves start yellowing cut back on the water. This is most common cause of death of interior potted plants.
