Good morning. I'd like to print out and give a copy of HG 84 (Pruning) to our mower, who's interested in such things. He'd get so much more out of a Spanish edition if it's available. I thought some of the publications were available in Spanish, but I haven't found them. Thanks for helping. Bob Nixon, Clarksville ###

Next spring I would like to plant six or seven evergreens at the edge of the wood line of tall trees located about 20 feet from my deck. They would get late afternoon shade. Which plants would you recommend and when to plant them?
I got into using Tru Green for tree and shrub insect and disease control several years ago when I had a very bad infestation of bagworms on my arborvitae. (I also have a fungus on my cherry laurels but what they use does not make it go away anyway and so I treat only the cherry laurels with a fungicide, myself.) So! I have not had any bagworm issues for several years,probabaly at least 4. I pay for 2 horticultural oil treatments per year and two insect and disease treatments, a total of 4 treatments. I really wonder if I need to do any of this anymore. No bagworms for 4 years or so and I treat the cherry laurels for fungus myself. Would I be safe in discontinuing all applications in your opinion? (I hate using these things but am afraid of losing my arborvitae.) A big thanks for any help!
I found this pod under a flowering bush that has beautiful red flowers during the summer. Can you tell me if it is a Calyanthus seed pod?
