The Christmas Cactus never fails to disappoint. Just two weeks ago, I discovered the pot was inundated with water (the decorative wrap around the pot hid this fact from me for weeks), and I was worried the buds would drop off. But wow, this year was a pretty good year. No aphids this time (they've found more tender foliage in my other potted plants), but only two new leaves this year. Even though there are a few buds hanging on, they will not bloom. If it hasn't bloomed by now, the bud will drop within a couple weeks.
Without new leaves, the plant does seem droopier than prior years. It happens to the best of us, my friend.
Merry Christmas to all, and may you produce blooms yet another year.
