How deep do Tiger Lily roots go? I want to plant something along the top of our wooded ravine lot that will grow in partial shade and protect the steep bank. What about Day Lilies? Any suggestions welcome, we are more concerned with preserving the edge of the ravine than flowers.

Ash Yellows Disease

We have a Bergeson ash in our yard in Halstad MN that has been dying back and yellowing for a few years. Is ash yellows disease found in our area? If our ash tree is diseased, is there any cure? If the tree has to be removed, will the disease remain in the soil and affect a new tree planted in the same spot?

For the second year in a row, my monarda plants have been eaten before bloom time. Today I was able to see several small yellow bugs about a quarter of an inch long, and also gooey black spots which I presume to be eggs all over the plants. The plants looked healthy just a few days ago. The bugs look nothing like the pictures on your web page, although I understand they could be in a different stage of development. Can you help me? Other info: our soil is very sandy, although we have had loads of rain this year. Nearby plants include peonies, johnny jump-ups, cat mint and day lilies. Nothing else has any issues.

I was at the MN Arboretum this week and walked the Wildflower Garden. We saw this plant - the leaves were wonderful in shape and scale. I'd like to figure out how to get it for my shade garden. Thank you!

Agricultural tile drainage

I have a couple of farms that are 80% clay and concrete tile. We have done bandaid work with plastic tile but I would like to drive up a holistic or master tile plan and learn about gated tile that I hear is on the horizon to understand if would apply. One parcel has an alkali problem at on the north half and erosion problems on the south half.
