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