Zone 6b Almanac. What growers here actually recorded: sowing weeks, days to first pick, and yields.

Dormant care

Start indoors

  • Alliums need 10-12 weeks under lights before they go out. The earliest sowing of the year.

  • Onionaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Match day-length to your latitude. Long-day north of 37°, short-day south.

  • Leekaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Plant seedlings deep in a 6 in trench and hill soil up the stem twice during the season. That buried length is the tender white shaft you're growing for.

  • Celeryaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Celery is a water crop: it turns stringy and bitter the moment it dries out. Keep soil consistently moist and feed steadily. Homegrown stalks are thinner and far more flavorful than store celery.

  • Lavenderaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Lean, gritty, well-drained soil and no coddling. Plant on a slight mound, skip the fertilizer, and prune a third of the plant after bloom to stop it going woody.

  • Celeriacaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Needs a long, steady season: start indoors early and keep soil evenly moist the entire time or the knob stays small.

  • Habanero Pepperaround Feb 14

    10 weeks of indoor growth before your last frost (04-25). Needs more heat and a longer season than bell peppers; start indoors early and don't rush it outside until nights stay above 55F.

  • Pepperaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Pinch first flowers on transplants so the plant invests in roots before setting fruit.

  • Parsleyaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Soak seeds 24 hrs before sowing. Cut outer stems and it comes back for years in mild zones.

  • Chivesaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Divide the clump every 3 years: one plant becomes six with no effort.

  • Oreganoaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Harvest just before flowering for the strongest flavor. Dries beautifully.

  • Thymearound Feb 28

    8 weeks of indoor growth before your last frost (04-25). Needs sharp drainage. Plant in gravelly soil or a raised bed edge. Never wet feet.

  • Sagearound Feb 28

    8 weeks of indoor growth before your last frost (04-25). Prune hard in spring to prevent woody stems and keep the plant productive for 5+ years.

  • Eggplantaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Eggplant sulks in cold soil. Transplant 3 weeks after last frost, not on it. Harvest while skin is glossy: dull skin means bitter, seedy flesh.

  • 8 weeks of indoor growth before your last frost (04-25). Sow thickly in a band and harvest by pulling every other plant: the rest fill in the gap.

  • Jalapeño Pepperaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Corking (light brown cracks near the stem) means the pepper is fully ripe and at peak heat, not damaged.

  • Poblano Pepperaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Picked green it's a poblano; left to ripen red on the plant and dried, it becomes an ancho chile.

  • Cayenne Pepperaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Thin-walled pods dry easily on the plant or strung indoors; harvest for drying once fully red.

  • Shishito Pepperaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Pick while still green and wrinkled for the classic blistered appetizer; about 1 in 10 fruits carries real heat.

  • Lemon Balmaround Feb 28

    8 weeks of indoor growth before your last frost (04-25). Cut back hard before it flowers and sets seed, or it self-sows into every corner of the garden.

  • Lovagearound Feb 28

    8 weeks of indoor growth before your last frost (04-25). Grows 4-6 ft tall once established; give it the back of the bed and divide the crown every few years to keep it productive.

  • Catniparound Feb 28

    8 weeks of indoor growth before your last frost (04-25). Fence it off if cats roam the neighborhood: they'll flatten the plant and any seedlings around it rolling in the scent.

  • Anise Hyssoparound Feb 28

    8 weeks of indoor growth before your last frost (04-25). Deadhead spent spikes to extend bloom all summer; bees and hummingbirds favor it over almost anything else nearby.

Direct sow

  • Daikon Radisharound Feb 28

    Soil is ready -8 weeks before last frost.
