The primary cause of misshapen carrots is root knot nematodes, which usually cause distinctive swellings (galls) the size of a pea on the roots of affected plants. They also cause forking and stubbing in carrots. These nematodes damage the roots and reduce the plant’s ability to absorb water and nutrients.

What does nematode damage look like?
Typical symptoms of nematode damage can appear above and below the ground in foliage and roots. Foliar symptoms generally appear in the form of stunting of plants, premature wilting, and leaf chlorosis (yellowing).
How do you get rid of root knots?
To kill nematodes in soil, heat small quantities of moist soil to 140°F in the oven or by solarization. Heating soil in the oven over a time period needed to bake a medium-sized potato placed in the center of the soil is sufficient to kill nematodes; however, this is only practical for small quantities of soil.
How do you reduce nitrogen in soil?
Add mulch to your soil, and stop fertilizing if you want to reduce the amount of nitrogen in your soil. Mulch uses up nitrogen as it breaks down, so applying a layer of dried wood or sawdust in high-nitrogen parts of your garden can suck up nitrogen. Nitrogen also leaches out of soil naturally.

Root-knot nematodes do not produce any specific above-ground symptoms. Affected plants have an unthrifty appearance and often show symptoms of stunting, wilting or chlorosis (yellowing). Symptoms are particularly severe when plants are infected soon after planting.
How do you know when carrots are ready to pick?
Carrots should be ready for harvest about 60-80 days after sowing seeds, depending on the variety. The tops of the carrot roots will be about 3/4 to 1 inch in diameter and likely starting to pop out of the soil, though not necessarily. They will also be vibrant in color.
How often should carrots be watered?
Carrots need about an inch of water per week when young, but as the roots mature, increase water to 2 inches per week. The best way to know if you need to water is to stick your finger in the soil about an inch deep near the plants (but don’t disturb the developing roots). If it’s moist, there’s no need to water.

How do you know if your plant has nematodes?
Symptoms. A root-knot nematode problem can be confirmed only by physically examining the roots for knots or by a laboratory test. Symptoms on affected plants may be evident on parts of the plant both above and below the ground. Above the ground, plants may appear stunted and discolored and may die.
