Q: A landscaper put a single cattail as a decorative touch by a dry creek he’d created in a flower bed. The first year it looked exotic. The second year, I was excited it returned. The third year (now) I spent a great deal of time this winter deep-digging each cattail to remove as much tuber as I could. Then I replanted the bed with perennials.

Q: We have a Linden tree that is maybe 12-15 years old, about 6 inches at the base. A couple years ago we noticed holes in the bark and last year the dog tore off the side of it revealing rotten wood inside. It has continued to produce leaves and appears healthy, except for the trunk. Is there anything we can do to save it or is it too far gone? – Benton County
Working together to reduce pesticides in our water It s important we all do our part to prevent pesticides from getting into our waterways.
The Clackamas River basin s fertile soils support a variety of robust harvests. The region s vibrant nurseries and Christmas tree farms bring joy to families nationwide. Gardeners boast blue-ribbon vegetables and harness our PNW rains to create lush, green lawns.
Many growers use pesticides to produce these bounties. Herbicides combat weeds, insecticides repel bugs that harm crops, and fungicides keep plants from getting plants sick.
Sometimes, these pesticides get out of the garden, however, and they can contaminate our waterways. Herbicides and insecticides in our streams kill the plants and insects that form the basis of our ecological food web. Pesticides bioaccumulate in fish that eat contaminated insects, threatening our endangered salmon species.

Q: We planted a ‘Cherokee Chief’ dogwood on March 23. It seemed to be doing so well. It was growing, and it bloomed beautifully. Then, this past week, we noticed problems on the leaves and blooms. We searched for answers, and checked with a local nursery. It appears to be fungus, perhaps anthracnose? So, last night around 7 p.m., I applied Ferti-lome Liquid Systemic Fungicide II containing Propiconazole. A surprising shift in the weather, brought rain in the middle of
