Chives can be a little tricky. I have always found that they take a bit of time to get settled. Usually a season goes by before they get established and you have to coddle until then.
The pretty garlic chives in the photo are in their second season. I didn’t show the other chives I planted in the same bed this spring. They are all weak and wilty, but have survived and should help fill in my 4-foot square bed.
Next year I will plant a couple more until I have a bed filled with chives. I have this little dream of selling herbs someday.
