Hi,

I have a baby Eden climber that has yellowish spots on the leaves. In the past week, the leaves that turn yellow just fall off. In the past 2-3 weeks, I have treated the plant with a homemade been oil solution (been oil, dish soap, water) to treat the sawflies that were attacking the leaves. That seems to be working to keep sawflies away, but I now have this problem. I know we had a bit of a drastic weather change (I.e. cool weather to 80s-90s) so I'm wondering if it's that? Also, fall is coming..Let me know what you think. Thank you!

Any kind of oil can cause leaf burn in high heat situations. However, I think you may have a case of black spot too.

What Seil said.

Thank you both! Do either of you know if blackspot is typical in autumn? Any treatment suggestions or tips? I saw a home remedy that included soap, a tiny bit of baking soda, and water.

In Michigan black spot is common any time! We tend to have a lot of hot days, cooler nights and high humidities. That's perfect BS growing conditions.

I don't like to recommend any kind of home remedies. They seldom work very well and they are often harmful in other ways. At least that one doesn't seem to have cooking oil in it! I literally cooked all the leaves off my roses once spraying them with a home brew that had oil in it. Oh, I didn't have BS for sure but I also didn't have any leaves left, lol! What ever you decide to use, never spray any thing but plain water on your roses if it is over about 75 degrees. Always spray early or late in the day. Never at the hottest, sunniest part of the day and always water your roses the day before and after to keep them hydrated. Personally, I've learned to look for roses that don't spot easily and to just live with the spots I do get.

As always, she speaks for me.

What is been oil?

I was wondering about that too.

LOL, on a hunch, I typed Neem on my phone and it wants to auto-correct to Been.

Aha, the joy of technical conveniences!
