Question by gone_nba

I read that this plant can grow better in water and so I put in a jar with rocks. After about a week the leaves started to get ruffled and then got yellowish. I took it out and half of the roots were gone and the rest of them are very very wet and they are like noodles. I put it into a pot with soil. What do I do and do you think it will live?

If I reply to anone emails that you people send; will you people reply back?

We cannot respond to a reply - it doesn't come directly to us. So you need to submit your questions through the Home Depot gardening site; we will answer and if you have further questions or comments, you can submit another question. Not the most convenient way for you, but necessary because of the way our Q & A forum is set up.

Your calla lily may recover now that you have it in a pot. Here are the basics for growing calla lilies:

To grow Callas indoors in a container. To pot the rhizome, first moisten the potting mix. Place the mix in a plastic tub and slowly add warm water, stirring with your hand until the mix is moist but not soggy. Next, fill the pot about 2/3 full of mix and set the rhizome, with the pointed growing tip facing up, on top of the mix. Cover the rhizome with the remaining mix. Water thoroughly and place in a warm room. Keep the soil evenly moist while you await the appearance of the shoot. When growth starts, set the pot in a sunny window (preferably one that faces south). Calla Lilies are one of the few houseplants that thrive in wet, even soggy, potting mix. To maintain a constant supply of moisture, keep the saucer filled with water. Bloom usually shows between 8 and 16 weeks after potting, depending on the amount of sunlight the plant receives. In summer, move the plant outdoors to a spot in full sun. Repot once or twice during the growing season. Bring indoors before frost. In areas where winter lows do not drop below 10?F, you can plant your Calla Lily in the ground in spring in an evenly moist or boggy location in full sun.

To grow Callas outdoors: Plant after danger of frost has passed in full sun or partial shade (partial shade is required in the South and warm inland areas of the West unless the soil is constantly wet) and rich moist soil. Rhizomes should be planted horizontally, with the growing points facing up. Grow in containers (3 per 12-inch pot) or in the garden. Rhizomes in containers should be planted just 3 inches deep. Hardy to Zone 9 (20?F), but an ample layer of mulch applied in fall can get plants through winter in Zone 8 (10?F) and even Zone 7 (0?). In colder climates, dig the rhizomes when frost threatens in fall and store them indoors in dry peat moss or sand at a temperature between 60? and 75?. Calla Lilies grown in a container can be left in the container over winter. Bring the container indoors in fall and withhold water completely until you want to start growth again in spring.
