How to Grow and Care For Vinca
When to Plant Vinca?
Although this is a very hardy plant when established, it’s best to wait until the soil temperature is 60 degrees or up to plant them and get them started. Vincas that are planted too early could become susceptible to fungal issues. This will manifest as yellowing foliage.
What Type of Soil Do Vinca Like?
Vincas are tolerant of any type of soil as long as it has sufficient drainage capability. Any soil or potting media that becomes easily water-logged is not a good fit for Vincas.
Does Vinca Need Sun or Shade?
Full sun is your best bet for peak performance, but Vincas can also do pretty well in partial sun as well. If you are planting in a partial sun situation, make sure you aren’t giving as much water as if it was in full-sun.
How Often to Water Vinca
Annual Vincas are native to semi-arid parts of Africa, so they are on the moderate to lower end for watering needs. Once established, they certainly have some drought tolerance, but make sure you are still somewhat regularly giving them water. Try and be sure to water your Vinca plants at soil level so that you don’t splash water on the foliage.
When to Fertilize Vinca
It’s really not necessary to fertilize Vinca plants, as they are light feeders. Fertilization could also lead to fewer blooms (and who wants that?!) so it is best to only fertilize at time of planting, or not at all.
Potential Pests & Diseases
The good news with Annual Vinca is that it rarely has any disease or pest issues requiring treatment!
