Is watering house plants with tea a good idea?
My late mother-in-law was an inveterate indoor gardener and tea drinker.

Mom could grow just about anything. In her care, any leaf that dropped soon took root and found itself in a pot of its own or cozying up and sharing a pot with an established plant. Every holiday plant outlived “normal” expectations. Her potted plants thrived. The plant populations of terrariums did so well that they needed to be transplanted. \\Mom was able to keep more than 100 plants at a time green and growing, and she was always ready to divide and share her plants.
When she moved out of her big house and into an apartment, she went through serious deliberations about how to cut back from the whole gang to a smaller representation of her favorites. “Extra” plants were donated to her colleagues who were still teaching to brighten up their classrooms. It turned out to be a fairly big chore for her to transport her gifts to various classrooms in different school buildings.
Even in apartment living, she often had more plants than windowsills to put them on. Mom just couldn’t help growing great plants.
One of her tricks was to water her house plants with leftover cold tea. Mom drank a lot of tea, and she liked it piping hot. Later, usually the next day, she used any tea left in the pot or cup to water her plants. She said it was good for them.
It’s a habit that I’ve picked up. Even though a cursory internet search hasn’t yielded any solid evidence about the benefits of using tea for watering plants, I plan to keep up the habit. My plants seem happy enough. Just as important, it makes me happy to remember a favorite gardener and tea-drinker as I tend my indoor garden.
