Vinca Minor Care Tips

Vinca minor is a relatively easy plant to care for, but it still requires some attention to ensure its optimal growth. Below are some essential care tips for vinca minor:

Light:

Vinca minor can grow in partial sun, partial shade, and full shade.
It is best to plant them in partial shade to prevent burning from direct sunlight.
Ideal for areas with dry shade or under mature trees where grass struggles to grow.

Soil:

Well-draining soil is crucial for healthy vinca minor growth.
Space the plants about a foot apart for quick coverage.
Thrives in compost-rich soil but can tolerate poorer soils.

Water:

While vinca minor prefers moist soil, it is drought-tolerant once established.
Water regularly to keep the soil moist, especially during hot and dry periods.

Temperature and Humidity:

Vinca minor is intolerant of frost and thrives in humid, wet climates.
Be mindful of night temperatures dropping below 50 degrees Fahrenheit and consider bringing the plants indoors during colder months.

Fertilizer:

Monthly fertilization with balanced fertilizer can enhance foliage color and bloom production.
While not necessary, fertilizing can be beneficial for plants in poor soil conditions.
