sorry for the forgotten link

I noticed it was next to your foundation. Could you have a problem with the soil not being acidic enough? I know azalea's like acidic soil. I think astilbes do too. Do you use an acid fertilizer to correct for the basic conditions you foundation is putting in the soil?

I tested the soil with my PH tester and it showed 4.5. I am not sure if it works right though, my soil tested pretty much the same all over the gardening portions of our property (couple of acres). Our soil is basically very dark brown all over the property, no soil stripping was done or maybe some, but that was about 45 years ago.

The soil in the affected area looks very good, drains well. I just realized, this year with so much rain, the soil was wet basically all spring and summer long. It was dry some times though. I also added coffee grounds in there this spring. Maybe I put too many coffee grounds there? I did add miracle gro to azaleas and rhododendrons once a week in spring and summer this year. It made my other azalea (left of rhododendron & not on picture) and rhododendron really healthy comparing to last year as I didn't use anything.
I was told I shouldn't plant an azalea in the affected area because it doesn't get any sun. The rhododendron to the left seems to be very well though.

I have a bad feeling I created the problem. Do you think I have a plant disease in there now?

thank you in advance

I retested the soil today morning. The value is right between 5 and 6. I didn't know soil's ph can change so much. The original testing (4.5) was done about a month ago.

Get a soil test done by a soil testing lab. This will give you accurate, reliable results. Check with your local extension for info.

we have had such a blah summer this year . with my garden all the nitrogen is being washed away causing browning to leaves this could be your problem to . try using a high nitrogen product on the soil . i use bone meal. around this time of year. this works for me . miracle gro is a good fertilizer too. too much rain can be harmful to your garden at times ha..

thank you, I will do that - fertilize with high nitrogen and add bone meal to the dirt.

I will get a soil test done by our county extension as well.

Surely, it is not those Giant Schnauzers! I love them.

The weather is probably the culprit here. Our azaleas are growing like crazy here....lots of acid soil. Great for the rhodos etc, but not so good for other plants.

Keep petting those schnauzers. We have had 5 minis. The best dogs ever.

Our dogs don't even get to that portion of the property. They have their own run and kennels.
I typically don't fertilize because all my plants look well without it. But in this time I will, I actually got the fertilizer yesterday. It was hard to find one with high nitrogen in this time of year, bot I got one with 16 (that was the highest I found without the other numbers being too high).
And yes, schnauzers are the best breed in the world - for me.
