Q. Calla Lilies

Last summer my calla lilies had plenty of leaves, but sadly no flowers. Could you give advice? Many thanks.

It is either the fertilizer or the sunlight. If you use fertilizer, you may have given them too much nitrogen, which encourages leaves and discourages flowers. If you suspect this may be the case, add phosphorus. Here is more info on phosphorus: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/phosphorus-plant-growth.htm

A lack of sunlight can happen if a nearby plant has grown to shade the area. Check the area and see if the calla lilies are getting enough sun.

Q. Tips of Green Foliage Turn Brown

Please tell me how to correct this problem. The tips turn brown on both spider plant and calla lily.

I'm assuming these are grown as houseplants. That being said, browning of leaf tips is generally normal and will not harm either plant. This is oftentimes the result of fluoride found in water, which causes salt buildup in the soil. It usually helps to periodically leach plants by giving them a thorough watering to flush out excess salts. Be sure to allow the water to drain out and repeat as needed. It may also help to use distilled water or rainwater when irrigating plants.

Q. Calla Lily in Containers

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?

Q. Calla Lily

My calla lily bulb is very soft in the compost. Should I leave it outside or has it died with the cold?

If the bulb is soft, there is nothing you can do, as it has rotted. Healthy bulbs are firm to the touch. It will need to be replaced.

Q. Overwintering in Pots

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?

Q. Calla Lily – Color of Blooms

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.

Q. Calla Lily Flowers

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.
