Full Answer

  1. Plant the mandevilla in a good location

    Plant mandevilla in a warm location that receives bright, indirect sunlight with good air circulation. The soil should be well-drained and rich in organic matter. Stake a trellis nearby for the plant to climb.

  2. Water, and feed the plant

    Water mandevilla when the soil is dry. Don't allow the vine to remain in standing water. Apply a 10-20-10 fertilizer around the base of the plant every other week during the spring and summer.

  3. Pinch, and prune the plant

    Pinch back the vines at a leaf axis during the spring when the plant is young. This will encourage a fuller vine. Remove any dead vines or vines crossing over others.

  4. Check for pests

    Check the vine for scale, mealybugs, red spider mites and whiteflies. These pests hide out on the underside of leaves. Spray them off with a strong stream of water.

  5. Protect the vine from cold temperatures

    Move the vine indoors when temperatures fall below 45 degrees Fahrenheit. Place the plant in a bright location, keeping it inside until the last frost.
