Are your plants getting enough sun?
Vinca flowers better when it's not shaded too much.

Colorado State's info on growing Vinca:
In most regions, plant vinca in full sun. In hot regions of the south and southwest, the plants appreciate some protection from midday sun.

Vinca prefers a slightly acid soil with a pH of 6 to 6.5. It needs a soil that drains well, but not one that is particularly rich or fertile. Dig the bed to a depth of about 6 inches and incorporate a one-inch layer of compost or dried manure before planting. If you plant in an existing flower border, the amendments you originally added there should suffice.

Mulch the soil around the plants, not only to help the soil conserve moisture and to deter weeds but also to protect the plants during inordinately rainy weather. A layer of mulch, such as bark chips, helps minimize splashing, which can transfer fungal spores from soil to leaves.

Fertilize monthly with a granular or water-soluble fertilizer.

Water infrequently if at all when the plants have become established in the garden.

In the midst of a hot summer drought, the leaves may curl up during the day. Don't worry. They will unfurl when evening arrives with its touch of dew.

You do not need to groom vinca by removing spent blooms; they drop off. Plants stay neat-looking all season.

When I transfered Vinca minor from a sunny spot to a very shady spot, my once flowering vinca stopped flowering.

Good luck! Hope this is helpful.

Most things are starting to look a little sad this time of year. The blooming season for vincas is pretty much over by late summer. Vincas are very hardy and we're sure they will be back next year just as lovely as ever. We have some in our yard that haven't been touched for over twenty five years and they come back every spring.

Vinca Plant Care

2016-12-15 20:20:39 · answer #4 · answered by ? 4 · 0 0

I'll ask one question before I try to answer; Are you asking about annual Vinca (Catharanthus roseus), Big leaf vinca (Vinca major), or the evergreen groundcover (Vinca minor)?

It would also be nice to know what USDA hardiness zone you're in, it helps us all answer your question well.

I guess my first thought is has it received enough fertilizer? Use a fertilizer higher in phosphorus (the middle number on the fertilizer package), I would recommend a water soluble sort, follow the directions on the label. The other thing is the amount of sunlight. The vining vinca's (major and minor) are good in shade to part sun. They primarily bloom in the spring. The annual form, blooms all season, but really should be in full sun to light shade.

Ultimately I think fertilization could help regardless of the form of plant.

I hope that this helps
Good luck-

Trim the plants back lightly and give them a very mild general fertilizer. Put a bit of compost around the base of the plants and water it in. It is getting late for doing any heavy fertilizing, but in the spring when the weather warms up give them a fertlilizer that aids blooming. Usually vinca are very hardy even to the point of becoming invasive. Water is good the first years and fertilizer helps them green up and bloom.

Are you watering them too much? Make sure to place in sun/partial shade. They are a very hardy plant.
