Why You Should Never Use Lemon‑Lime Soda on Houseplants

A reader asked if regular (non‑diet) lemon‑lime soda could “feed” houseplants like it does cut flowers.

Absolutely Not

Houseplants should receive only water (preferably distilled) and a balanced fertilizer formulated for plants. The only other beneficial addition is a bit of compost tea in late spring.

Soda, coffee, alcohol, and other household liquids usually harm or kill plants.
