I have a sad looking snowbush (breynia nivosa roseo-picta); it's leaves are drying and falling off. The soil is kept moist; it is placed indoors near a french door (direct am light and indirect light throughout the rest of the day); it's in Santa Barbara, a couple of blocks from the ocean (night temperature probably drops to about 50 degrees). Does anyoun know how to make this plant look happy again? Esti
