August 30, 2022Q.What Is The Fastest Growing Sedum That Will Be Used For Ground Cover In Full Hot Sun (Missouri)
I had Vinca Vines on a hill to prevent dangerous mowing and they about all died this year, either due to over watering at one point or the extreme heat. I will plant Seedum next Spring 2022. We had planted 66 plants about 6-7 yrs ago and they had almost all filled in. They looked GREAT this spring, but now about all dead. I would like a fast growing seedum to plant on that hill. It does get full hot sun. Please advise. Thanks!

Certified ExpertA.Actually, you have quite a selection within the genus, and outside of the genus!

July 5, 2024Q.Leaf Problem On My Autumn Sedum
All of the leaves on my sedum have developed brownish spots, and some have a black film that wipes off. The stems are strong and are not effected. The plant seems to be growing fine and is not dropping leaves. I see no insects.

Certified ExpertA.The small, white things could be aphids, which produce honeydew, a sweet, sticky substance that causes sooty mold. Here is more:

ukQ.Sedum (stonecrop) Issue
In previous years this sedum spectabile (stonecrop) has been stunning. However, this year it hasn’t flower and seems to be ill. It has produced lots of flower heads but the flowers haven’t opened and have turned brown and dry. Large brown lesions on the leaves. Earlier in the year I suspected powdery mildew and treated for that, but it didn’t seem to help. We moved the sedum in spring from its usual spot using good planting technique, lots of drainage etc. It has been a very wet summer here in South Wales, UK though. Would like to know whether it will survive next year if cut back hard, or if it’s time to say goodbye to this plant. It’s in a central location in the garden and depressing to look at! Any advice greatly appreciated!

Certified ExpertA.I would suspect the wet season for being the reason that it is dying. I would treat it with fungicides as early as possible, but take a few baby pups from it as well. You may want to take those inside and baby them. Treat them with fungicides often and keep a close eye on them.

April 10, 2025Q.Autumn Joy Sedum Drooping After Division
I divided some of my Autumn Joy Sedum yesterday & moved to a sunnier location. They already had growth (6+ inches), but I didn't cut them back before dividing. I watered them lightly yesterday. Today they're MUCH less green in color and looking droopy. What should I do? I know they don't like being overwatered, but should I water lightly again today? Should I cut them back at this point, or will they recover on their own? Thanks for any suggestions!

Certified ExpertA.They likely are in shock from the move. Keep them lightly watered till they recover, then cut back on the watering. Here is more:
