Q.Why Is My Vinca Minor (periwinkle) Not Flowering?

Zone ZE2 9LH | stromfirth added on October 14, 2020 | Answered

It has been growing in the same place for over 15 years and is very healthy looking, south facing but in the far North of Scotland (Shetland) where we have less sun and it is a colder and harsher environment. I’ve only seen two small flowers that cam out in October!

I would advise testing the soil soil for nutrient deficiencies or pH imbalances. Usually, this will have something to do with too much nitrogen and not enough phosphorus and potassium in the soil. It could be that the soil pH is off enough to prevent uptake of these nutrients, as well.

Here are some articles that will help:
