Schultz 8-14-9 African Violet Plus Micro-nutrients
I filled out the contact form at www.schultz.com with questions about the percentage of Nitrogen in their product made up from urea. It seems to be widely believed urea is bad for African Violets. An entire new industry seems to have grown up promoting the fact that they DON'T use it in their products and nearly everything written will scream not to use it.
I did find one article written by Joyce Stork in an old AVSA magazine from Nov/Dec 2009 titled, "Urea-Based Fertilizers" on page 51. She suggests many articles written have condemned urea based fertilizers because "it is the safest course of action." She seemed to feel some of the cases being blamed on this ingredient had other issues associated with the problems.
Of course, I bought some :)
It was the AV plant food with the least percentage of Urea I could find locally out of 4 stores I checked with.
So I wondered why a well established company would continue to include it?
When you wonder something, you should go looking for answers!
This was their very swift company reply:
Thank you for contacting United Industries.
Nitrogen can come in many different forms, each of which has different qualities. Some, like nitrate nitrogen, are immediately available to the plant and others, like ammoniacal nitrogen and urea nitrogen, become available over time. That is why, as you see, our Nitrogen consists of three different types, which ensures that the plants will get some nitrogen immediately, and some later.

I will add the usual cautions:
"If what you're using works, don't change what you're doing!"
Time will tell how my plants do.Perhaps an excellent experiment once I have an over abundance of offspring to play with. Which of their directions should you follow? Half strength every watering? Once a month at the full dose?
For now I'm leaning towards a happy medium - half strength middle and end of month.
(Will entertain any and all advice!)
