Mandevilla Vine

The Mandevilla vine is a beautiful addition to your garden and can be easily grown in pots or planted in the ground to scramble up a trellis.

These vines thrive in warm weather and are covered in blooms continuously throughout the summer, which is why I will always include them in my garden.

They are pretty easy to care for, but because they are heavy bloomers they will benefit from a good fertilizer once in a while and a consistent watering schedule.

They are tropical plants so will only survive outside in zones 9 – 10, so you could decide to treat them as an annual and buy them from your local garden center every year, or decide to overwinter them.

If you decide to overwinter them, there are a couple of options to try:

  1. Overwinter indoors: Cut it back to a manageable size and place in the sunniest location that you have available.
  2. Overwinter as a dormant plant: Cut it down to about 8 inches and water well.  Add a thick layer of mulch, and place it in a dark location such as a basement or garage. Water every 3 weeks or so and bring it outside once the danger of frost has passed.

It’s not guaranteed that your plants will survive, but it may be worth a try.

 It is important to note that the plants are slightly toxic, so care needs to be taken around children and animals.
