Soil testing

Hello, Do you know who I might contact to have my soil tested? I've had a raspberry bed growing well for years, then last season the plants all died. Kaput! So, I thought I might have the soil tested for possible contamination by my neighbors. Perhaps I just have poor clay soil. Maybe the experts can tell me. Thanks for your advice.

Cyd-x for codling moth control

We have a few apple trees and are trying to control codling moth. A product called Cyd-x seems to be a hopeful solution but it is only available in quart containers for $400+ . Can you advise if there is a source for this product in smaller quantities for backyard gardeners? Thank you

Identification question

Could you please tell me what these two weeds are in my yard, and if the red spots mean the plan is diseased. I think the plant might be some kind of dock, but I'm not sure. Thanks!

Rainer Cherry Tree and Jasmine

Hi. I live in Corvallis and I want to plant a cherry tree and a jasmine plant and I was wondering if you could tell me the best variety or recommendation/place to get the trees. My favorite cherry is the Rainer. My neighbor has a cherry tree, but I am not sure what the variety is--it is a red cherry--in case that helps with questions of pollination. Specifically, I would like to know where I could get a Rainer tree. I see that there are dwarf kinds and regular kinds and I don't really know what to get. Additionally, I love the smell of jasmine and would like to plant some. Could you direct me to the best variety. I see that there are climbing ones and bush jasmines. I have places where a climbing tree could work, as well as a place in my garden to plant a bush. I am looking for the ideal variety in terms of fragrance. (I want the most fragrant-but also the ideal variety to grow in our area). And if you know the best place to purchase, I would appreciate it. Thank you in advance!

Eradicating Thistle

Hello, I have a group of students willing to help me remove two patches of thistle on Wednesday. What is the best approach to this if we are trying to not have the thistle return in spring. Should we cover the area with cardboard to tarps after we remove thistle by hand? I believe we are dealing with bull thistle. Alison

Powdery Mildew on Pine Bark bush

I plan to dig out my pine bark bush that is infected with powdery mildew. How do I protect another bush that I hope to plant in that same spot? How do I stop the spread to my other bushes? Are there mildew spores in the soil? Do I need to sterilize the soil? And if so, what do you recommend?
Thank you for your help.

Philodendrun root disease problem

I have long-term Philodendron cuttings living for many years in three vases of water in my house. Always healthy, zero problems until now. This summer they started developing spotted places on their leaves, some minor leaf curl on their edges followed by fully brown/dead leaves dropping from the plants. Next I discovered the white fungus on the stem joint sections above the water level. These collections are more than 25 years old, always perfectly healthy and much enjoyed. Q: What can I do to rid them of root fungus or root mold, not sure which. Recently I have tried Hydrogen Peroxide (3%) : 6 tablespoons in 1 pint of water, soaking for 1/2 hour then full rinse and back into clean water. Not working after two attempts.
