Growing Asparagus in Zone 7B

Asparagus is the garden’s long-term investment. Plant it once and harvest it for 20-30 years. The patience required in years 1-2 pays off in decades of spring harvests.

Zone 7B enjoys a long growing season. You can often get two plantings of cool-season crops (spring and fall).

Top Growing Tips

• Plant crowns (not seeds) 4 weeks before last frost for fastest establishment
• Dig trenches 12 inches deep; set crowns 18 inches apart with roots spread out
• Do NOT harvest any spears in year 1; harvest lightly in year 2
• Full harvests begin in year 3 when the bed is fully established
• Let fronds grow all summer — they feed the crowns for next year’s spears

Companion Planting

Good companions: tomatoes, basil, parsley, asters (repel asparagus beetles)

Avoid planting near: onions, garlic, potatoes

Harvest Timeline

Beginning in year 3; harvest spears when 6-8 inches tall before tips feather out
