Question
My Calla lily has never flowered in about three - four years. Can you advise where it should be planted and care it should be given. It is looking green and has plenty of strong foliage, but no flowers!

Answer
Hi Pat,
Thanx for your question.  If the plant is experiencing too much shade, this can cause flowering to decrease or become non-existent.  Use of fertilizers high in nitrogen can cause all green growth at the expense of flowering.  The soil should be moist but not soggy, free draining and even allowed to dry out from time to time.  The plant will benefit from direct sunlight 6 or more hours a day.  In very hot climates, the plant does better with afternoon shade.  Use bone meal to help induce blooming.  If you are using lawn chemicals (for the grass), make sure the chemicals are not leaching into the soil of your flower bed as these chemicals are high in nitrogen and will cause lush green growth at the expense of flowering.  I hope this helps.
Thanx,
Tom

Expertise

I have been a gardener for 20 years with perennials both growing from seed and from nurseries. I went through the Master Gardener Program from Kansas State University Cooperative Extension Service and I answered questions on the Hotline a few years ago for the Wyandotte County Kansas Extension Service. I have also lived in the Florida, California, Hawaii, Arizona, Texas, Kansas and Missouri and am experienced with a variety of climates, soils and weather conditions.

Experience

I have been growing perennials for over 20 years now. I am self-taught mostly except for a master gardener class. I have experimented with all kinds of perennials including many that are not common to my area. I have read hundreds of books and grown hundreds of varieties of plants and hope to make it a business some day. I have become versed in botanical names and growing conditions and what I don't know off of the top of my head I can usually easily find in my vast array of research material and botanical and horticultural contacts. I especially enjoy experimenting with growing plants out of zone.
