The Gardener's Best Potato Grow Bag is ideal for growing carrots. Potting soil (planting mix): The Potato Grow Bag has a capacity of 50 quarts. We suggest our Container Mix. Ordinary garden soil should not be utilized since it will not drain easily in the grow bag. Instead, use a soil-based potting mixture such as Perlite or Pro-Mix. Water regularly: As with any other vegetable, water carrots at least once a day, more frequently if they appear dry. If your soil is very dry, water plants weekly until the weather improves.
Carrots like plenty of sunlight and well-drained soil to grow in. They can also benefit from some compost added to their habitat. If you'd like to grow carrots in a potato bag, here's how: select small carrots with green tops. Snip off the tops of the carrots to about 1 inch. Then peel back the skin and clean out any debris. You can leave the roots intact, but we recommend cutting them into smaller pieces than usual so they'll fit better in the bag.
Put the cut carrots into the bag, fill it up, and press the vegetables down so they're covered by at least 2 inches of soil. Don't worry about covering all the carrots; just make sure there are no empty spaces where heat can build up.
When planting carrots in a potato bag, don't cover the top of the bag.
You can make a container out of almost anything, including old buckets, tubs, and bins, as long as it can hold soil and has a drainage hole on the bottom. Plan on growing five carrots for every gallon of potting soil in the container. Fill the bucket about two-thirds full with soil and plant your carrots. They will need space to spread their roots so give them at least 1 inch between each carrot. Cover the tops of the carrots with some plastic wrap or aluminum foil to keep weeds away from their tops while they are growing. When the carrots reach about a foot tall, start pinching off the tops of the plants. This will cause them to produce more carrots! Keep harvesting the tops until all the carrots are used up. When planting carrots, choose a location that gets morning sun and afternoon shade. This will help them grow healthy and avoid any one part of the carrot getting too hot or cold.
Carrots like well-drained soil with plenty of nitrogen in the form of compost or fertilizer. If you don't want to use money on fertilizer, then chicken manure is an excellent source of nitrogen. During flowering time, be sure to provide some phosphorus in the form of bonemeal or rock phosphate. After harvest, remove the remaining carrots and place them in a storage bin with an equal amount of fresh soil to maintain the nutrients in the soil.
To spread their roots and develop to a healthy size, standard carrots will require at least 18 inches of soil. Smaller carrots such as baby carrots can be planted in containers as small as 12 inches across.
When planting outside in the garden, plan on allowing 30 inches between rows. This will allow room for growing and give your carrots space to grow into large plants.
In warmer climates, it is not unusual for carrots to be planted early in the season and harvested before the first frost. If you are planting carrots outside in areas where temperatures fall below 40 degrees F, consider covering the plants with an outdoor fabric cover until the weather becomes more moderate.
Carrots like well-drained soil with a high phosphorus content (if using commercial fertilizer), evenly distributed over the bed. Carrots like light soils, so don't plant them in heavy soils or those that have been heavily worked or tilled. Space plants about 1 foot apart when you start them from seeds and again once they reach about a foot in height. The closer together you plant them the shorter your carrots will be!
Water regularly and apply some form of organic fertilizer once a month starting about three months after you plant them.
