The Best Carrot Soil - Sandy Loam
The best carrot soil consists of a sandy loam mix of aged plant and animal compost. It should be loose so it falls through your fingers.
Aged Plant Animal Compost
The best carrot soil consists of a sandy loam mix of aged plant animal compost. Carrot soil should be loose, falling through your fingers when scooped up by hand. It should have a ratio of 30 percent silica based sand, 30 percent soil matter and 40 percent compost. A soil with pebbles, stones or clay will not grow great carrots. In fact, more than likely carrots will be stunted and deformed.
Carrot seed should be sown just below the surface, about an inch down for best results. Seeds should be spaced two-inches apart in rows. Carrot seeds will not germinate in soil that’s too warm; a temperature between 45 and 55 Fahrenheit is ideal.
Fertilizers & pH
Carrot soil pH should be between 6.5 neutral and 7.5 alkaline. Carrot soil can be fortified with Potassium to increase carrot sweetness. A man-made fertilizer or wood ashes are good sources. Novice gardeners make the mistake of adding Nitrogen to carrots, which caused excessive top growth and root branching.
Overwatering can cause a myriad of problems including “root rot” and the “carrot fly”. Carrots hate to be watered from above because water tends to collect and sit for days in dense carrot tops before it evaporates. Watering periodically underneath the carrot top canopy will mitigate many of the diseases and pests associated with overwatering. Crop Circles are great for this.
