Planting

• When moving your mandevilla into the great outdoors, look for a sunny location, though the White Delight will do well in partial shade, too. Install a trellis near the planting area as the vine will easily climb and provide you with shade as well as gorgeous flowers. Mix in enough potting soil or compost to elevate the planting site, raising the mandevilla slightly. Dig a hole that is approximately two times wider than the container the plant is currently in, but no deeper.
  
  Place your hand at the base of the plant and invert the pot, wiggling gently to remove the plant. Position the plant in the center of the hole, disturbing the roots as little as possible in the process. Push the fill dirt in around the plant, pressing lightly with your fingers to compact the loose soil. Add water and a root stimulator, if desired.
  
  

Feeding

• Since the mandevilla is such a prolific flowerer, it will require regular applications of fertilizer. Apply an all purpose plant food every two to three weeks during the spring and summer to encourage the formation of more blossoms.
  
  The root system on the White Delight originally developed under hot, arid conditions. As such, it is able to act as a reservoir of sorts, holding enough water to keep the plant well hydrated for prolonged periods of time with no additional water. Make sure the soil around the plant is completely dry before adding more water, or when the glossy green foliage begins to look a bit dull. And when you do water your vine, pour the water out very slowly, giving the roots time to re-absorb the moisture.
  
  

Protection

• When the weather begins to cool off, dig your mandevilla up, cut it back until it is approximately 12 to 15 inches in height and place it in a pot that's large enough to support the root structure. Choose a pot that has plenty of drainage so the soil will dry out properly between watering. Place the plant indoors in a sunny location. Once the temperature reaches an average high greater than 65 degrees Fahrenheit for three weeks in a row, feel free to return the vine to the great outdoors.
