Mandevilla
Earlier this year I asked for some advice on
growing Mandevilla. I now have a plant in my conservatory about 6ft tall and 3ft wide covered in bloom. I'm wondering how I can overwinter it.? Tom Atkinson |

Dunno, but I have a Mandevilla boliviensis that I hope to keep going :-) My guess is that it shouldn't be much trouble, provided that your conservatory stays comfortably above freezing. As I understand it, Mandevilla laxa is nearly as hardy as Passiflora caerula, but is rather more sensitive to waterlogging in winter, and Mandevilla boliviensis is happy as long as not waterlogged and above about 2 Celcius.

As I understand it, Mandevilla laxa is nearly as hardy as Passiflora caerula, but is rather more sensitive to waterlogging in winter, Against a sunny wall in the south, it acquits itself quite well out of doors once established. It hates a windy spot though and regardless of summer warmth, makes little growth in such positions. ... and Mandevilla boliviensis is happy as long as not waterlogged and above about 2 Celcius. About right, although some of the hybrids prefer it a bit warmer to around 5C. That is not to say they wont survive at lower temperatures, but they are more susceptible to damp-induced grey mould and are less eager to 'wake up' in spring. Keeping them nearly dry at root helps and plenty of freely moving air will deter the mould. The very glamorous 'Alice du Pont' will easily overwinter here outside and even hold on to many of its leaves. However, it almost always dies away after making a feeble amount of growth in late spring. That's the problem with growing such plants in a mild maritime climate. Getting them through winter is less of a problem than arranging for a continental-type heat surge in spring to really get them going again in spring.

Growing season: March - November Although I can only dream of growing Alice Du Pont outside I can and do have a 15' specimen in an unheated greenhouse and although it is obvious it would prefer it warmer! it survives well, usually flowering till Jan then sulking until April, before coming back into growth. The chief problem is Botrytis (never know if I have spelt it right!) so I have a small circulating fan in there on 24 hours a day which seems to hold it at bay. -- Charlie, gardening in Cornwall. http://www.roselandhouse.co.uk Holders of National Plant Collection of Clematis viticella (cvs) |
