How to Use Miracle Grow

By Katie Jensen ; Updated September 21, 2017
Get seedlings off to a good start with fertilizer.

Miracle-Gro, a water soluble fertilizer, comes in both a granular and liquid ready-to-use form. Plants absorb the fertilizer through their leaves and roots. According to the company's website, Miracle-Gro contains all the micro-nutrients needed for healthy plant growth. The company states that plants regularly fed with Miracle Gro will grow faster and if used according to directions, and the fertilizer will not burn plants.

Granular Miracle-Gro

Add 1 tbsp. of the granular food to 1 gallon of water. Water plants by wetting down both the leaves and the soil.

Fill a Miracle-Gro Garden Feeder sprayer with one prepackaged plastic bag of Miracle-Gro. Attach hose. Turn on hose full force. Turn the lever on the feeder to the on position. It will take a moment for the sprayer container to fill with water and dilute the granular food. Spray plants for about 15 seconds each for large plants and 5 seconds each for smaller plants. Each prepackaged bag will spray for 12 minutes, covering about 500 square feet.

Empty a new bag of Miracle-Gro in the sprayer and continue feeding plants until all have been fed. Sprayer may be stored with Miracle-Gro remaining in it.

Repeat feeding every week to two weeks.

Miracle-Gro LiquaFeed Garden Feeder

Attach the feeder to hose. The feeder has four settings and allows watering as well as feeding so there's no need to remove it. Turn on the hose and the feeder to the selected spray pattern.

Spray plants for about 15 seconds to cover leaves and wet the soil. Each bottle lasts for 14 minutes and covers 400 square feet.

Spray plants every 7 to 14 days while plants are growing.

Insert new bottle when the old one is empty.
