Common Mistakes Growing Cilantro in New Jersey
- One common mistake among New Jersey gardeners is not accounting for the late spring frosts that can still occur in early April. To avoid losing your cilantro plants, ensure that you wait until after April 1 before sowing in areas classified as Zone 7a.
- Many New Jersey gardeners overlook the importance of crop rotation and succession planting. Planting cilantro too closely together or repeating location year after year can lead to a decline in herb quality and increase pest issues.
- Another frequent error is attempting to transplant cilantro seedlings. This herb has a taproot, meaning it does not respond well to being moved after germination. Direct sowing is the best strategy to get a healthy crop.
- Humidity can be an issue in New Jersey during the summer months, often leading to bolting. To tackle this, ensure you sow in early spring and again in late summer, taking advantage of the cooler conditions.
- Gardeners often underestimate the impact of high temperatures on cilantro in New Jersey. Be prepared to monitor their growth, as rapid spikes in temperature can quickly lead to bolting and reduce the flavor of your harvest.
