Miracle‑Gro offers several liquid plant‑food formats: all‑purpose liquid concentrates, indoor pump‑applied plant food, an organic liquid plant food, a water‑soluble bloom booster, and a Protect & Shine leaf spray.
Application intervals vary by product. Labels recommend schedules such as weekly (every 7 days), every 7–14 days, or every 2 weeks depending on whether the product is for indoor houseplants or garden use—always follow the specific product label.
Dilution and dosing depend on the product type: garden concentrates often use cap fill lines (for example, fill the cap to a mark and mix with a set volume such as 2 gallons to feed a defined area), houseplant concentrates give teaspoon or capful measures per gallon, and pump‑style indoor formulas use pump counts (e.g., 1 pump for small pots, 2 pumps for larger pots, or 4 pumps per quart). Follow the label for exact measurements.
They’re intended for a wide range of plants: houseplants and indoor plants, flowering plants, vegetables and herbs, shrubs and trees, and both container and in‑ground garden plants. The Protect & Shine spray is specifically for hard‑leaved indoor plants.
Protect & Shine is used as a miticide, insecticide, fungicide and leaf shine for hard‑leaved indoor plants. Labels advise against using it on soft‑leaved or fuzzy plants such as African violets, succulents, and cacti.
