Miracle-Gro Water Soluble All-Purpose Plant Food 10 lb — Fast-Acting 24-8-16 Fertilizer for Indoor & Outdoor Plants

Miracle-Gro Water Soluble All Purpose Plant Food (10 lb.) is a fast-dissolving, general-purpose fertilizer formulated to feed indoor and outdoor plants quickly and evenly.

Whether you grow potted houseplants, beds of annuals, vegetable rows or established shrubs, this water-soluble formula delivers essential nutrients to roots as soon as it's mixed into water. The 10-pound tub provides broad coverage for large garden areas and includes a scoop for easy measuring. Use the product in a watering can, with a garden feeder, or as a routine soil drench to support steady growth and greener foliage compared with unfed plants.

How do I mix and apply this plant food for indoor containers?

Mixing for indoor use is quick and precise: use the small end of the included scoop and dissolve the powder in a gallon of water. Apply as a soil drench at the base of each plant every two weeks to supply nutrients without risking leaf burn when used as directed.

• Indoor ratio: 1/2 teaspoon per 1 gallon of water
• Application frequency: every 14 days for houseplants
• Method: soak soil at the plant’s base rather than spraying foliage
• Scoop included for repeatable measurements

What’s the right way to feed outdoor beds, vegetables and flowering plants?

For outdoor plants, dissolve the recommended larger scoop size in the specified volume of water and apply as a root soak every 7–14 days during the growing season. The formula is designed for use on flowers, vegetables, roses, shrubs and trees when used according to directions.

• Outdoor ratio: 1 1/2 tablespoons per 1 1/2 gallons of water
• Frequency: every 7–14 days depending on plant needs
• Also compatible with Miracle-Gro Garden Feeder for larger areas
• Best practice: water soil at the base to target roots

What nutrients are in this mix and why do they matter?

This all-purpose formula is labeled with an N-P-K ratio of 24-8-16, supplying nitrogen for leaf growth, phosphorus for root and bloom support, and potassium for overall plant function. Those three macronutrients work together to help plants access energy, build structure and respond to environmental stresses when paired with proper cultural care.

• Nitrogen (24): supports greener, fuller foliage
• Phosphorus (8): contributes to root development and flowering
• Potassium (16): helps with plant vigor and water regulation
• Water-soluble for fast availability to roots

How much area does one 10 lb. container cover?

The 10-pound tub is sized for homeowners and small-scale gardeners, covering roughly 4,000 square feet when applied per the package instructions. That makes it practical for feeding multiple containers, garden beds, and lawns in rotation without frequent repurchase.

• Approximate coverage: feeds about 4,000 sq. ft. of garden area
• Suitable for both container and in-ground use
• Works with hand watering, watering cans or garden feeders
• Bulk size reduces packaging waste and trips to the store

Miracle-Gro all-purpose formula useful. It fits routines that rely on regular, measured feedings—especially gardeners who prefer flexible application options like watering cans or feed-through garden tools. Follow label directions and measure consistently for safe, repeatable results.
