Hortiscope: Where to go for horticulture info 
Readers: With my exit from the Hortiscope column and retirement, I have been asked by many how to get information on horticultural problems.
The answer simply is to contact your local NDSU Extension agent. If the agent is not sufficiently schooled in horticulture to answer your questions, he or she will know where to turn to get the answer.

Hortiscope: Cut your roses back in fall for best results
Q: I have several questions about different plants. I would like to know if I can trim a schefflera plant. I have a nice plant that was given to me for my son’s funeral. The plant sits in my enclosed sunroom by an east window. It is very big, so I’m wondering if I can cut some of it off.

Hortiscope: Insects cause of sap issue
Q. We have an old silver maple tree that we have trimmed three times in the past 15 years. The most recent trimming took place earlier this year.
This summer, I noticed a lot of sap all over everything on my deck, which is underneath the tree. My husband says he’s seen it do this before, but I have not noticed it before and I am out on the deck more than he is.

Hortiscope: Watering, calcium both related to end rot
Q: I read your article about blossom end rot on tomatoes. All the articles I have read say to give the tomatoes some calcium. It does work, so the rot has nothing to do with watering. I figured a man in your job would know better than to say it is the watering.
