They have now hybrided a PERENIAL Mandavilla "BUSH"- NOT VINE. Are the care instructions the same even though one is a perenial, and one is a an anual (at least here in Northern VA), and one is a climbing vine, and the other a bush.? How big does the bush get?- i need to make sure i give it enough room to always have room to grow. Also, do they require total direct sun all day, or can they take "X" amount of minimum sunlght, and some, if any shade?. Do they require any special treatment in the fall to ensure survival through the winter? How often should you water them? What about feterlizer? What kind of PH balance do they like? What type of soil combo (if necessary) do they need when first planted? Is there a particular way to prun them- should need be. What can you do to ensure it continues to bloom and bloom, and do they bloom all summer, and maybe into early fall? How fast do they grow- are they slow or fast growers?
