Calla Lilies

    I live in northern Wisconsin, I would like to plant calla lily in clay pots and start them in the house in a south window ( 1 bulb per pot) Then place them outside.  Is it possible? How soon should I see growth and how soon should I place them outside?

    You can start the rhizomes indoors in full sun. Plant them so that the tips is just below soil level, the rough nubby side up.   They sould come up in a couple of weeks. Water and keep moist but not wet. Move outdoors when night temperatures are no lower than 50 degrees. The initial blooming time can be 8-14 wks depending on variety and growing conditions.
    White callas (Zantedeschia aethiopica) take 11-14 wks, cooler temps and need moist soil. Colored hybrid callas (Zantedeschia hybrids) can take 8 wks to bloom, warmer temps and less moisture.
    Calla lilies are  summer blooming plants hardy in zone 7-10.  They will not tolerate frost, if outdoors so be sure to dig them up in the fall and store them slightly moist in a cool, dry place for the winter. Calla lilies are not hardy in Wisconsin.

    Deer resistant?
    deer have eaten my calla lilies

    Hi Sue
    The deer must have been very hungry. Calla lilies are listed as seldom severely damaged, deer usually will not eat them.

    The calla is in the front window with full morning sun in the house. and it gets evening sun as well. I am fertilizing it also. I put it outside last year in the sun and it did the same thing. I wondered if it needed to be put in a bigger pot that was deeper.

    Tall/weak stems
    I have a huge calla that was given to me after my mother passed away. The first season it went to seed and I harvested the pods. It has yet to bloom again. But the biggest problem I am having is that the leaves are so huge and long that they are heavy and weight of them they bend and break they are about. 2-3′ long I don’t know how to keep the long leaves from doing this. Does it need to be down in the pot further? I have a post that I put in the pot and took some yarn and tried to tie the stems up so they don’t bend and break but it didn’t work. Any suggestions would be helpful. I have pictures of it if anyone would like to see what I am referring to.

    Hi Kerri
    Looks like your calla lily needs more sun. Low light and warm temperatures can produce tall and weak stems that will bend over. I would slowly increase the amount of sun it is getting. When the weather warms up, slowly acclimate it to the outdoors by placing it in the shade. Are you fertilizing the plant?

  • Get more tubers
    how do i get new bulbs.i want to give bulbs to friends.

    Hi Sonya
    If you have a healthy plant growing outdoors, calla lily will produce more tubers which can be divided in early spring or late fall.

    I live in East TX and bought some calla lilies at a local store. Yesterday, I clean out the flower beds and just placed the lilies, in their container, around in the bed. This morning I went to plant them and noticed that something cut off one of the flower stems. It also ate part of the inside of the stem. Could this be an insect or possibly one of the local moles? The container was not knocked over. I found signs of a mole’s tunnel, but no signs of where it came up nor paw prints.

    Hi Brenda
    My guess would be a mole or small critter.
