There are several reasons why carrots and radishes may not form roots properly. One reason could be that they were planted in hot weather, as they germinate best in soil temperatures between 55 and 75 degrees F. If the soil is too warm, the seeds may struggle to germinate. Warm temperatures can also dry out the soil, making it difficult for the seeds to germinate. To retain moisture, you can cover the seeds with grass clippings or a row cover. Another common cause is heavy soil, such as clay, which prevents good root formation and can result in twisted roots. To improve heavy soil, you can add sand, broken down leaves, or well-rotted compost before planting. However, be cautious about using too much nutrient-rich compost, as excess nitrogen can lead to beautiful green tops but poor root development. Overcrowding can also hinder root formation, so it's important to thin the seedlings to 1-2 inches apart a week after sowing, and then thin them again to 3-4 inches apart a few weeks later. Insufficient water can also affect root development, so it's recommended to water deeply once a week in most soils, and more frequently in sandy soil or during periods of heat and drought. Lastly, root-knot nematodes can cause deformities. A soil test can confirm their presence, and if they are found, solarization (using plastic sheeting to heat the soil) or moving the them to a different location may be necessary.
