Ingredients in Miracle-Gro Plant Foods


It's one of the best-known brands to gardeners and soil toilers around the world. Miracle-Gro potting mix, fertilizers and other plant and vegetable additives can create better blooms and plumper vegetables. The brand’s long-standing reputation as a quality product is a given, but what’s in Miracle-Gro? Whether you're working an acre or a patio container garden, Miracle-Gro is a go-to for getting the best out of the crops and flowers you grow. Let’s take a look at what’s inside the iconic yellow and green packaging that features a bouquet of roses, flowers, vegetables or fruits for a better understanding of what makes it work so well.

Breakdown of a Good Fertilizer

Any good fertilizer worth its salt, so to speak, includes the right mix of a few major ingredients. Nitrogen assists in the photosynthesis process so the plant can produce chlorophyll and proteins. Phosphorous helps the plant in developing starches and sugars, which assists in blooms and crop production. Potassium is a workhorse, getting absorbed by the plant's tender roots to assist in the ongoing process of photosynthesis. A lack of any can make the plant wilt or wither.

Miracle-Gro Ingredients

Whether you buy a liquid plant food, blue crystals or bags of soil, the Miracle-Gro products can all be read the same when it comes to understanding the ingredients. The major brand’s plant food ingredients include a mix of nitrogen, phosphorous and potassium. Each package of Miracle-Gro plant food has three numbers showcased on the front of the package or in the ingredients list. These are essential plant food ingredients. The numbers indicate the levels of nitrogen, phosphorus and potassium. All of these are needed in any type of soil if you want your crops to flourish. The brand’s go-to fertilizer, Miracle-Gro All-Purpose Plant Food, has “24-8-16” on its packaging, meaning it's made of 24-percent nitrogen, 8-percent phosphorous and 16-percent potassium.

Benefits of Buying Miracle-Gro Soil

When you wish to succeed in gardening, start with the soil. A good soil mix gives the plants a kick-start in the place where they're planted. No matter what you plan to push into the dirt, whether seedlings or mature fruit trees, Miracle-Gro has a soil for your specific planting needs. The Miracle-Gro potting mix ingredients include sphagnum peat moss, aged bark fines and fast-acting nutrients to give plants a good start. The kicker is the slow-release plant food that supports the roots and plant throughout the growing season. Perlite and coconut coir, which is ground coconut husks, round out the mealy mix of ideal nutrients for plants. Miracle-Gro has many different mixes of ingredients for varying conditions and plants.
