About Tom Alonzo
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.

Expert: Tom Alonzo - 10/9/2008
Question
I have many yucca plants. 2 plants are invaded with 1000's of small black bugs with red heads. They seem to change the leaf color to a pale yellow. I would like to correct this problem before they invade additional plants. Thank You for any assistance.
Answer
Hi Karen,
Thanx for your question. Sounds like a yucca bug to me.

The link above has a picture. Use Merit or Orthene to get rid of these bugs. I'm sorry, I don't have an Organic method of control at this time. If you prefer organic, let me know your state and county and I'll find someone who can help you. I hopet his helps.
Tom
