Zone 10b Almanac. What growers here actually recorded: sowing weeks, days to first pick, and yields.

Start indoors

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

  • Onionaround Nov 6

    10 weeks of indoor growth before your last frost (01-15). Match day-length to your latitude. Long-day north of 37°, short-day south.

  • Rosemaryaround Nov 6

    10 weeks of indoor growth before your last frost (01-15). In zone 6 and below, grow in a pot and overwinter indoors near a south window.

  • Leekaround Nov 6

    10 weeks of indoor growth before your last frost (01-15). 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 Nov 6

    10 weeks of indoor growth before your last frost (01-15). 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 Nov 6

    10 weeks of indoor growth before your last frost (01-15). 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 Nov 6

    10 weeks of indoor growth before your last frost (01-15). Needs a long, steady season: start indoors early and keep soil evenly moist the entire time or the knob stays small.

  • Habanero Pepperaround Nov 6

    10 weeks of indoor growth before your last frost (01-15). Needs more heat and a longer season than bell peppers; start indoors early and don't rush it outside until nights stay above 55F.

  • Lemongrassaround Nov 6

    10 weeks of indoor growth before your last frost (01-15). Pot it up and bring it indoors before frost north of zone 9; a clump easily overwinters on a sunny windowsill.

  • Pepperaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Pinch first flowers on transplants so the plant invests in roots before setting fruit.

  • Parsleyaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Soak seeds 24 hrs before sowing. Cut outer stems and it comes back for years in mild zones.

  • Chivesaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Divide the clump every 3 years: one plant becomes six with no effort.

  • Oreganoaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Harvest just before flowering for the strongest flavor. Dries beautifully.

  • Thymearound Nov 20

    8 weeks of indoor growth before your last frost (01-15). Needs sharp drainage. Plant in gravelly soil or a raised bed edge. Never wet feet.

  • Sagearound Nov 20

    8 weeks of indoor growth before your last frost (01-15). Prune hard in spring to prevent woody stems and keep the plant productive for 5+ years.

  • Eggplantaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). 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 (01-15). Sow thickly in a band and harvest by pulling every other plant: the rest fill in the gap.

  • Jicamaaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Needs 150+ frost-free days: outside zone 8+ it's best in a greenhouse or very large container brought in before frost. Pinch off flowers so energy goes into the root, not seed pods, which are toxic.

  • Jalapeño Pepperaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Corking (light brown cracks near the stem) means the pepper is fully ripe and at peak heat, not damaged.

  • Poblano Pepperaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Picked green it's a poblano; left to ripen red on the plant and dried, it becomes an ancho chile.

  • Cayenne Pepperaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Thin-walled pods dry easily on the plant or strung indoors; harvest for drying once fully red.

  • Shishito Pepperaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Pick while still green and wrinkled for the classic blistered appetizer; about 1 in 10 fruits carries real heat.

  • Lemon Balmaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Cut back hard before it flowers and sets seed, or it self-sows into every corner of the garden.

  • Marjoramaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Tender compared to oregano; treat as an annual outside zone 7 and bring a pot indoors for winter if you want it to persist.

  • Steviaaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Pinch flower buds as they form; once it blooms, leaf sweetness drops off sharply. Overwinter indoors north of zone 8.

  • Lovagearound Nov 20

    8 weeks of indoor growth before your last frost (01-15). 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 Nov 20

    8 weeks of indoor growth before your last frost (01-15). Fence it off if cats roam the neighborhood: they'll flatten the plant and any seedlings around it rolling in the scent.

  • Anise Hyssoparound Nov 20

    8 weeks of indoor growth before your last frost (01-15). Deadhead spent spikes to extend bloom all summer; bees and hummingbirds favor it over almost anything else nearby.

  • Culantro (Recao)around Nov 20

    8 weeks of indoor growth before your last frost (01-15). Slower to bolt than cilantro and holds flavor in heat; harvest outer leaves and the rosette keeps producing for months.

  • Papayaaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Plants can be male, female, or bisexual. Set three or four seedlings per spot and thin to the one that flowers with fruit behind it.

  • Passionfruitaround Nov 20

    8 weeks of indoor growth before your last frost (01-15). Fruit ripens after it drops. Let it fall, collect it daily, and hold it a week until the skin wrinkles for the sweetest pulp.
