My mom bought me a Christmas cactus two years ago, and I immediately felt sorry for it. It was going to have to rely on me for its continued existence. The first year, it formed buds, and then they all fell off. It was very sad.
Then I remembered an image from my childhood. My grandmother's Christmas cactus, sitting underneath the canopy of a willow tree all summer. She didn't do anything to it. If it rained, it got watered. If it didn't rain, it didn't. All she did was bring it in when the weather turned cold.
Which is what I did this year. It's blooming a little early, but it's not like I mind. Once again, my grandmother knew best.
