Chives: Spacing, Yield & Planting Dates

About chives

Chives are a perennial allium that return reliably each spring, providing mild onion-flavored snips for garnishing and edible purple flowers for salads.

Spacing & yield

Chives wants 6×12 inches and about 0.3 lb per plant at ~80 days to maturity.

Growing tips

• Divide established clumps every 3-4 years to maintain vigor and prevent overcrowding.
• Cut back entire clump to 2 inches periodically to stimulate fresh, tender regrowth.
• Allow some flowers to bloom for pollinators and edible garnish, then deadhead to prevent aggressive self-seeding.
• Start from seed indoors 8 weeks before last frost, or divide existing plants in spring.

Common mistakes

• Never dividing clumps, which become crowded and produce thin, weak leaves.
• Letting all flowers go to seed, resulting in chive seedlings appearing throughout the garden.
• Cutting too many leaves at once from young first-year plants.

Harvest & storage

Snip leaves at 2 inches above the crown throughout the growing season, beginning about 80 days from seed.

Use fresh for best flavor; freeze chopped chives in ice cube trays for winter use.

Companion planting

Good neighbors for chives: carrots, tomatoes, roses, grapes, strawberries. Avoid planting beside: beans, peas.

Planting calendar

Start indoors about 8 weeks before last frost, then transplant 2 weeks after frost. Perennial — can also divide established clumps. Use the seed-starting calculator above with your real county frost date — the April 15 default is only a worked example (zone 6 style).
