Have you fed it a lot? It could be fertilizer burn. These need a ton of water, and can be utilized as pond plants. They also need a lot of sun in order to retain their black color.

Susan

thank you for your advice it may have been getting way to much shade I have it in the sun now so will wait and see
nope haven't over fertilized just feed it once so far
Thanks again

I am having the same problem!! I purchased my black magic about 5 weeks ago I planted it in a bed with my hostas, top soil dirt only in this bed, shady area gave it plenty of water and the leaves were drying up like leaves do in the fall it starts around the edges and after about 3 days the leaf is dry and crunchy. I do get wind I wondered if they could wind burn. I moved the plant to a large pot 2 days ago it has 1/2 miricle grow potting soil and 1/2 cheap potting soil I moved the pot to a sunnier location I pray it does better here. I would HATE to lose this plant my mother thinks I'm such a good gardener so she purchased it and it was already potted and so preety and not cheap. I feel like I'm letting down my plant and my mom.
UNLIKE the black magic,
My outher elephant ears are happy in the filtered shade and top soil.

My Black Magic is in a bog situation with 3 inches of water over it in full sun and it's doing fine. They like lots of water.

They also like sun. The more sun, the blacker the leaf will be. In shade, the leaf will eventually revert to green. Water, water, water is absolutely essential to the colocasias, like 'Black Magic'. They can even tolerate standing water, e.g., ponds, bogs, etc.

They also like rich soil, with compost, manure, and fertilizer added to your top soil. Top soil only is not going to be enough for these beauties.

I have moved mine to a smaller pot and put it in my pond and it is looking up got 2 new leafs and hoping it will keep growing

Sounds like you're doing the right thing, Sheepie! Kay, do you leave yours in your bog over winter, or do you bring them inside?

Susan

Mine usually come back up from the winter just leaving them out. If you decide to store them, I would pot them up. Have not had good luck with just bringing in the bulbs. Sounds like the ones you have gotten were greenhouse grown. When planted out they will usually lose the greenhouse leaves and sprot new ones.
