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. [ Hello Elizabeth R. - many thanks for any help you can suggest] Susan P.

What am I seeing in my cooked apple slices?

While many of the applies have been attacked, probably by the coddling moth, I have cut out the bad parts, sliced up the good parts and steamed them. Some of the cooked slices have small little substances. Does anybody know what they are? Is there a facility that could examine them with a microscope?

What are these insect eggs?

Can you help me identify these insect eggs? I don’t want to harm them if they are something beneficial. They were placed within the past few days on a tropical “Rio” plant near my front door. Thanks!!

Strange Plant Popped Up, What is it?

Hi Folks, I grow Oregon native plants on my property, including some listed plants (I have permit); an odd plant popped up in an area I cleared after my nine foot P. cardwellii died of old age. Out of curiosity, I let it grow and last night it opened up, stayed in bloom so far this morning. It looks alien and is likely either invasive or ornamental. I would like to know the plant name/species. It is quite large, competitive of the adjacent sunflowers; about 2.5 feet leaf tip to tip and now about two feet high. The photos were either taken early morning; the flower is a light lavender away from the center. Thank you, Jim Smith Albany, Or

Should we worry about these bugs?

Hi there,. We recently purchased Douglas fir lumber in Portland Oregon for a home renovation project. We have found lots of these bugs on the lumber. They appear to be light sensitive. The penny gives scale-they are less than a 1/4 inch in length. Should we worry about these critters doing damage to our wood? Is there a treatment for the lumber, or should we try to return it? Thanks!

Soil additives

I'm new to Oregon as of 6 weeks ago. I moved here from Miami Beach where it was A LOT easier to grow. I moved into a house where there were raised beds but the soil was tan and looked as if it severely lacked nutrients. The soil is very dusty and doesn't seem to hold much moisture. I've since transplanted that soil and added soil conditioner and compost. I've planted some carrot plants and I plan to plant the rest of my crops from seed. I want to know the best way to rehab that soil in order to get the best yield. Can you all help me? I'm planning to plant leafy greens and se of the better growing crops for this area. I have another box that is 12' x 6' and the rest of a 5'x5' box that the carrots are planted in.

Black fig production in sept.

Hi, I have a black fig tree-7 ft. tall. It is still producing baby figs. There are about 100 half grown ones. Should I pick the new baby figs? Will that direct growth to the older, bigger figs? Its Aug.29. Thanks in advance, Bob Abbott

Privacy screen arbor shrinking annually

For the third year in a row during the month of August, I’ve watched my screen lose it’s northern-most end member. I haven’t watered that section this year (last 2 years I assumed it was over-watering and root-rot). Still seeing an annual loss on the northern-most end of the line.
