Common Mistakes Growing Chives in New Hampshire
- One common mistake New Hampshire gardeners make is planting chives too early, risking damage from late frosts. In areas like Concord, where the last frost can be as late as May 11, it's crucial to wait until the danger has passed.
- Many novice gardeners ignore soil quality, which is vital for chive growth. New Hampshire has a mix of clay and acidic soils that may require amendment; ensure you add compost or well-rotted manure to provide essential nutrients.
- Some gardeners transplant their chives too late in the season, missing the optimum growth window. In Zone 5b, delaying beyond the last frost on May 11 can limit the chives' growing period and overall health.
- New Hampshire's humid summer can lead to overwatering, causing chives to rot. Monitoring soil moisture regularly will help maintain the delicate balance they need, especially in the wetter, more humid months.
- Failing to cut back chives regularly after they mature is another mistake. This can divert their energy into seed production rather than leaf growth. Keeping chives trimmed encourages lush, flavorful growth for continuous harvest throughout the season.
