colocasia esculenta

The older leaves on this year old plant (restarted from bulb this spring) have brown and yellow edges. It is in a container that gets morning sun only; lots of water and is fertilized regularly. Is this common for the leaves as they age or is it something else? The new leaves are green and healthy looking.

it is normal for the older leaves to turn yellow and long as the plant is putting out healthy new leaves things should be ok......Brent :)

Thank you Brent for your response. I've just recently obtained a baby "illustris" and am watching out for a good deal on "black magic" as I've really come to like these plants. Trying to make my zone 3 patio look a little like the tropics in the summer months!

Yes, the leaves normally "cycle". But I don't think that is the case. Please submit a photo. I suspect you are overfertilizing it, and/or the soil is dry. Its tricky because it can be moist to the touch, but be dry lower down if your drainage is "too good". Again, submit a photo is your best chance at a much more accurate diagnosis. Don't shrug it off, it may be a problem. You may have to do a soil transfusion and fertilize less. What kind of fertilizer is it? If it is anything other than time release granules, or miracle grow liquid, I will probablly frown on it.
