How to Grow Carrots in Grow Bags


Carrots are a cold season biennial plant used in cooking, but also delicious raw. The edible portion of the plant is the root, which grows straight down into the dirt. A grow bag, made of canvas or other porous material, is a soft container to grow carrots in. Grow bags are easily moved around, allowing you to plant wherever there is available sunlight and space, as opposed to being confined to a small patch of soil outside.

Step 1

Fill the grow bag with potting soil until it is nearly full, packing down to ensure the bag is filled with as much soil as possible. Knead the bag to break up the soil again and prevent compaction, says the BBC website.

Step 2

Make a few small slits at the bottom of the bag with a pair of scissors for drainage.

Step 3

Plant the carrots seeds in the bag at a depth of 1/4 to 1/2 an inch, with no more than three seeds per inch, in the early spring says the University of Illinois Extension. Space rows 12 to 18 inches apart. Water the bag thoroughly.

Step 4

Thin seedlings once they reach 1 inch in height so that there are only one to two seedlings per inch.

Step 5

Fertilize once a week with a complete, water soluble fertilizer with a ratio such as 10-20-10 or 12-24-12. Prepare the fertilizer according to the package instructions, pouring directly into the grow bag soil.

Step 6

Harvest the carrots when the carrots roots are 1/2 inches in diameter for finger carrots, which takes around 50 days, or 3/4 of an inch for other varieties in 60 to 70 days. Dig the carrots from the soil, and rinse before use.
