I've had BYS for years in my garden. There is something very dark brown, almost black which has spread all over most of the leaves. Do you know what it is and how should I deal with it.. I'd also like to know how and when to transplant volunteers.
Hi, Nina. It sounds like your black-eyed Susans have a fungus. The most common treatment is to use a fungicide such as chlorothalonil. As for transplanting, the best time to do this is mid- to late spring, though even early summer would be fine. Good luck!
This year, the deer are eating the black eyed susans and cone flowers!!
Seems nothing is deer resistance.
Deer will eat anything if they are hungry enough but they certainly see some plants as candy and others as distasteful. Here is a list of deer-resistant plants: https://www.almanac.com/deer-resistant-plants
Worse than ever this year. What I see are earwigs, though I saw a slug elsewhere on the property. What can I do that wont hurt the dog or the good insects?
Slugs- Egg shells or anything that is ruff edged.
Baking soda around plant based.
Use neem oil or insecticidal soap. Search on this site for natural pesticides: https://www.almanac.com/organic-pesticides
Last year I planted several red and orange black eyed Susan's. They grew and were beautiful. When they came up and flowered this year, they are only yellow flowers. What happened to the fed and orange ones?
It IS a mystery with many flowers ! except hydrangea (where you put down more folic acid plant food on them) and they change color from blue to pink or a mix! and get purple ! My neighbor does this. For me, it was ROSE OF SHARON bushes out back. They are all rootings from my mother's home which bloom the lavendar color --- last year the 3rd bush bloomed white ! How in the world did that happen! Heaven sent.
This question comes up a lot about different flowers … and we do not have an answer. It’s a mystery. If anyone out there has an answer–or a theory–pls share.
