I planted giant mail order white Calla lilies in containers outdoors this spring. Got great looking foliage but no blooms. Fertilized monthly and kept moist but no lilies. Plants look great and are still growing in an enclosed but unheated patio. I'm about to let them go dormant but how can I ensure blooms next year?
You may have given them too much fertilizer. Fertilizer with too much nitrogen will cause this to happen. This article will help:
How long will it take my calla lily to bloom inside? I just repotted the bulb from last year.

Approximately how long does it take the rhizomes to come up after they are planted? Every article I have read gives instructions on what to do when the leaves appear, but I have no idea how long it takes for the leaves to appear. The oriental lilies I planted at the same time are beginning to come up. They are in pots in the greenhouse. The temperature varies from about 58 degrees at night to 80 degrees during the day. They were planted March 10.
Quality rhizomes, which are ready to sprout, usually take 3-6 weeks. Varieties with larger blooms take longer. Make sure you obtain rhizomes from reliable source. Temperature is normally a factor, with estimated time based on 70 degrees F night temperature and 85 degrees F day temperature.
My mother recently passed away and a couple of friends sent calla lilies instead of cut flowers. One of them is a large plant, the other is about half the size. I would like to keep these but have never cared for one of these plants. Can you help me?

I planted some calla lilies in a pot for the summer. To overwinter them, I placed the pot in my greenhouse on a bottom shelf and did not water. The greenhouse is heated but it will still drop down around the freezing mark (I'm in Zone 5). I checked on them yesterday and the bulbs have all rotted. What is the best way to overwinter them in pots? Do I still need to lift the bulbs?

When I purchased my potted calla lily, it had pastel color blooms. Now it has dark red blooms. How can I change the color back to the pastel hue? What kind of fertilizer should I use?
Some calla lilies blossoms darken (and also some lighten) as they age. There is no way to get back the pastel color other than wait for the flowers to bloom again next year, when it will go through the same process.
I received a Calla Lily plant (Zantedescia species) as an Easter gift. I've kept it indoors as a house plant. Almost immediately two of the plant's smallest leaves turned yellow. So after watering it thoroughly and immediately draining off excess water, I cut off the yellow leaves. Now two of the bright yellow flowers are wilted with yellowing stems that have turned downward. Should the older flowers that are dying back be cut off either at or close the the soil level in its pot? Also, I can put the plant outside in the ground around May to avoid frost. Perhaps it does not like the sunny window with full afternoon sun in our house right now.
