I grow chives in the Long Island plot, and they are the least demanding plant in the herb section. A clump established from a transplant in spring comes back every year, requires minimal watering once established, and produces from March through November in zone 7a. The main management task is dividing the clump every three to four years when it becomes overcrowded, and cutting back the flower stalks if you want continued leaf production rather than seed.

Chives are worth planting early in a garden if you want a perennial that gives something useful in the first year and continues for a decade without replanting.
