How Do You Take Care of Vinca?


Vinca flowers are a popular addition to gardens because they are easy to care for and produce large amounts of beautiful blossoms. Caring for them requires mulch, a trowel, a hose, fertilizer and a natural insecticide.

  1. Give them enough sunlight

    Vinca plants thrive when they receive full sunlight. Keep them in a warm area that does not drop below 60 degrees Fahrenheit.

  2. Remove weeds

    Keep the growing area free of weeds. Remove any debris near the plants, such as rocks, leaves or sticks.

  3. Surround the plants with mulch

    Using your trowel, disperse a layer of mulch 1 to 2 inches deep around the plants. To keep the vinca plant from rotting, make sure to leave 2 to 3 inches of space between the plant and the mulch.

  4. Water as needed

    Vinca flowers are drought-tolerant, but they should be watered whenever the surrounding soil is dry. Don’t wet the plant itself. The soil should be moist 6 inches deep. Water in the morning so the daytime sun dries the moisture.

  5. Fertilize the vinca plant

    Feed the plant fertilizer once every month. SFGate recommends using a 10-10-10 water-soluble fertilizer that contains potassium, nitrogen and phosphorous. Unless the package says otherwise, add 1 teaspoon of fertilizer to every gallon of water, and water as usual.

  6. Remove and prevent pests

    Aphids and mites can be problematic for vinca plants. Use a strong hose stream to knock them off of the plant as necessary. For serious insect infestations, spray vinca plants with insecticidal soap or horticultural oil.
