Is it Safe to Plant Carrots in Miracle-Gro Potting Soil?


It is safe to plant carrots in Miracle-Gro potting mix. Carrots grow well in containers and Miracle-Gro potting mix is made specifically for container-grown plants. For best results, mix Miracle-Gro potting mix with a non-fertilized potting mix to lower the initial amount of nitrogen.

Cut Back the Nitrogen

Carrots are usually provided with half the required nutrients worked into the soil before seeding and half added when the seedlings are 3 inches tall. Fertilize lightly with 1-2-2 fertilizer when the seedlings are 3-4 inches tall.

Lightweight soil

Carrots require loose, light soil without stones or clods that can cause the roots to split. Miracle-Gro potting mix fills this requirement. It contains organic materials that keep it from compacting in the pot. A wetting agent spreads water throughout the mix to help it drain and maintain air pockets.

Container Selection

Grow carrots in containers that are at least 12 inches deep or twice the size of the mature carrot root. The pot must have drainage at the bottom. Fill the container with potting mix to a depth of 11 inches. Wet the mix thoroughly before planting carrot seeds at a depth of a quarter inch.

Choosing the Seed

Choose a smaller carrot variety for container gardening such as Thumbelina, Short 'n Sweet or Little Finger. A mix of Miracle-Gro and non-fertilized potting mix provide an excellent growing medium for any of these varieties.

Moisture Requirements

Carrots require moist soil conditions during the entire growing season. Miracle-Gro potting soil contains wetting agents that disperse water throughout the pot. This helps keep the soil uniformly moist.
