Question
Hello Greg,

I have an aloe that seems happy to be in a container outside in Dallas, TX.  It has new "shoots" and its moisture content seems fine.  However, it is losing its green color at the ends of the leaves and turning brown/pale, though the consistency of the leaves remains the same.  Is this too much sun (is that even possible?)  What should I do to keep it a healthy green? (I give it organic fertilizer regularly and water once a week in summer).
Thank you,
Jennifer Piehl

Answer
Dear Jennifer,

I have seen Aloe's that do what you are describing, and usually this is normal on older leaves. Watering once a week seems excessive, even in summer (unless it is in direct sunlight). I would only fertilize once a month and only use half the reccomended dosage.

Chances your Aloe is fine unless this is happening on new leaves. If it is, it may be a sign of "crown rot" which occurs when it is over watered. You can tell two ways, by either pulling on the newest leaves (if they pull out with little or no effort, there is rot present), or if you can smell a foul smell eminating from your plant.

Hopefully this is not the case. Hope this helps.

Sincerely,

Greg
