Blue Agave Yellow Tips: Normal Aging vs. Watering Issues in Heavy Pots

Diagnosing Yellow Tips

• Bottom leaves only: Often natural senescence as plant matures.
• Widespread + soft: Overwatering/rot.
• Widespread + firm: Nutrient deficiency or sun stress.

The Wiggle Test

Grasp center leaves; rock gently:

• Plant + pot move together: Roots intact, likely healthy.
• Plant moves, pot stays: Root loss/rot—urgent action needed.

Watering by Pot Type & Climate

• Plastic pot + humid: Monthly max.
• Terra cotta + hot/dry: Every 2 weeks summer.
• Rock top dressing: Prevents finger test; use pot weight or moisture meter at side.

Action

Remove rock layer if possible. Check soil moisture at drainage hole. Adjust watering to climate/pot. Yellow tips alone rarely kill agaves.
