My wife bought a dwarf rosebush in a pot last Valentines day, a lovely gesture but not entirely practical, since we live in a apartment with no balcony or garden. I've kept it on a window ledge which gets a lot of sun, but it's just not enough. It has produced no flowers at all since she bought it, few if any new leaves, and its old leaves are now more yellow than green -- although they're not wilted at all. We are now moving home, in the next few weeks, to a house with a good, south-facing garden, and I will put the poor thing outside on arrival. Hopefully, good exposure to the sun will see some healthy leaf production, and with luck, a few flowers! The problem is that we still need to get through several months of winter yet, during which -- outside or in -- it still won't get huge quantities of natural sunlight. It's in such poor health that I wouldn't be surprised if it didn't have enough stored sugar to survive until the spring. Can anyone suggest ways and means of enhancing its chances?
