Why Did My Plant Die?

We all kill plants, even us professionals. If you're wondering why your plant died on you, there are a few important things to remember about how plants live and grow. Plants need enough light, water, and carbon dioxide to drive photosynthesis. If they don't get enough of each or all, they'll be in trouble.

Respiration is how plants burn calories, and respiration doesn't stop just because the lights are out or you forgot to water. Your plants will burn energy even if there is not enough light, water, or carbon dioxide available. If those inputs remain limited or cease, eventually your plant will burn more energy than it can generate. Like this plant, which is now TOAST. Because I forgot to water it.
