Common Mistakes Growing Cabbage in New Mexico
- Many New Mexico gardeners underestimate the impact of late spring frosts on their cabbage seedlings, especially in higher elevations. Transplants should not go out before the frost date to avoid severe damage.
- Some beginners in New Mexico plant cabbage too late in the spring or too early in the fall, resulting in poor head formation due to summer heat or frost exposure. Timing is essential for healthy growth.
- Neglecting soil pH is a common mistake for cabbage growers in New Mexico, especially when growing in more acidic soils. Liming your soil if it falls below 6.5 can significantly reduce clubroot risk and contribute to healthier plants.
- New Mexico's humidity can lead to slugs becoming a major pest issue in cabbage crops. Many gardeners forget to use preventative measures like slug bait or copper tape, leading to significant damage during the night.
- Ignoring crop rotation can cause cabbage diseases to decimate your yield. Many growers in New Mexico overlook this critical practice, leading to issues like clubroot reappearing in brassica crops year after year.
