I recently bought a dragonfruit, that at the moment only has one main growth. There is one flower bud that may or may not open soon. It was doing fine for awhile, staying green and looking healthy but suddenly some of the tips of the leaves are shriveling and the bud is turning a reddish yellow in some areas. Is it going to survive? Or is it going to shrivel and fall off? I don't have it in full sun (as far as I know) it only gets filtered morning sun. It's mostly in shade. I'm watering it enough and not letting the soil become too dry. I think that's right because its a tropical cactus and not a desert one? Also, when I bought it, it already had a full grown fruit on it and a smaller fruit with a dried flower still attatched, sadly that one fell off :( I think It got knocked off somehow.
