Q.Watering a Perlavilla once trained
I don’t know how to water my Perlavilla mandevilla plant and let the water drain away once it is in a trained position. At the moment, it is just trailing and I am watering it outside to let the water drain away. I wonder if you could also clarify how to maximize flowering, as another site mentions cutting off the top above the flower.
I'm listing links with care information.
Water when the plant dries out.
I think your referring to pinching back the plant, this will help your plant become fuller and bushier.
A trellis or support is necessary for your plant to grow on.
