Why do my periwinkles/vinca shrivel up and die one by one?
Question:I have tried to plant them for years, but everytime they brown and wither then completely die. I have changed the soil completely and they die one at a time so I don't think it's the amount of light they are getting or they would all look bad.
Answers:
planting them too early in the season
They respond well to sun but need lots and lots of water either morning or night. I have planted them for years and have great succss. They even tolerate heat.
They do need a lot of water. I have many vinca in containers and must water them at least every other day. They also require a lot of sun. They can stand partial shade (that is, shade in the morning or afternoon), but don't do well in a very shady area.
Mine are pretty hardy, but they are easy to lose if they don't get enough water.
You want mine? They are taking over my lawn and garden!!
Mine live in a shady spot under the trees in my yard, and have just kept spreading. I'm not sure what kind of nutrition is in that soil, but it's much more damp.
