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

Transplant out

  • Sweet Potatoaround Feb 5

    Safe to set out 3 weeks after last frost. Plant rooted slips, not seed. Wait until soil holds 65F, then let vines sprawl and cure roots at 80F for 10 days before storage: that curing step is what makes them sweet.

  • Eggplantaround Feb 5

    Safe to set out 3 weeks after last frost. 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.

  • Okraaround Feb 5

    Safe to set out 3 weeks after last frost. Okra wants hot soil, 70F+, or seed rots. Pick pods at 3-4 in every other day: one pod left to toughen tells the plant to stop producing.

  • Jicamaaround Feb 5

    Safe to set out 3 weeks after last frost. 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.

  • Malabar Spinacharound Feb 5

    Safe to set out 3 weeks after last frost. Not a true spinach; it's a vigorous heat-loving vine that replaces greens through the hottest weeks other greens can't survive.

  • Lemongrassaround Feb 5

    Safe to set out 3 weeks after last frost. Pot it up and bring it indoors before frost north of zone 9; a clump easily overwinters on a sunny windowsill.

  • Avocadoaround Feb 12

    Safe to set out 4 weeks after last frost. Avocado roots suffocate in wet soil. Plant on a low mound in coarse, fast-draining ground and never let irrigation water pool at the trunk.

  • Bananaaround Feb 12

    Safe to set out 4 weeks after last frost. Each stalk fruits once and dies. Cut it down after harvest and keep one or two suckers so the clump keeps producing.

  • Papayaaround Feb 12

    Safe to set out 4 weeks after last frost. 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.

Direct sow

  • Okraaround Feb 5

    Soil is ready 3 weeks after last frost.

  • Winter squasharound Feb 5

    Warm soil: first summer sowing of winter squash.

  • Beetaround Feb 12

    Warm soil: first summer sowing of beet.

  • Carrotaround Feb 12

    Warm soil: first summer sowing of carrot.

Garden care

  • Mulch every bedaround Feb 5

    3-4 in of straw or leaves now holds water, blocks weeds, and cools roots for the whole summer.

  • Switch to fewer, longer soaks (1-1.5 in/week at the root) instead of daily sprinkles.

  • Tomatoes, peppers, corn and squash get compost or fish emulsion once fruit sets.

Succession sow

  • Bush beanaround Feb 12
