What to plant this week in Sacramento, CA

Week of 2026-W36

Sacramento's current heatwave means your summer crops are sprinting toward harvest, with watermelons and zucchini ready to pull from the soil by week's end. With frost dates firmly in January, you can aggressively sow warm-season seeds like Malabar spinach and sweet corn while managing the intense afternoon sun that defines our valley climate.

On the ground

Growing in Sacramento right now

  • The Sacramento Valley's heavy clay loam retains moisture well but cracks dry; water deeply early morning to prevent runoff during this week's forecasted rainstorms. Avoid overhead watering on hot afternoons to reduce fungal pressure on your basil and nasturtium beds. Mulch heavily around young beans and corn to keep soil cool despite the 95°F+ highs common in late spring.
  • While our lowland zones usually see reliable spring rains, check local forecasts for any sudden deluges that could splash soil onto leaves of your cucumber and squash plants, increasing powdery mildew risk. If heavy rain is predicted, delay sowing delicate seeds like French marigolds until the ground drains faster.
  • Be aware that our distinct microclimates mean riverfront gardens may stay cooler than inland neighborhoods; adjust planting times for frost-tender items if you are on the western edge of the metro area where temps dip closer to 50°F at night.

Seasonal tips

  • Sow heat-loving seeds directly into warm soil after the last frost date passes.
  • Thin out dense seedlings like beans and corn to ensure proper air circulation.
  • Apply a light layer of mulch around established plants to retain moisture as temperatures rise.
Keep watch

Pest & disease watch

  • Watch for aphid colonies forming on the tender new growth of your shiso and Thai basil due to the combination of heat and recent moisture. Spray with neem oil in the early morning if populations exceed five per leaf.
  • Slugs are becoming active again after last week's rainfall, targeting low-growing nasturtiums and young bean seedlings near irrigation lines. Use copper tape or diatomaceous earth barriers around transplant beds this weekend.
Water

Watering this week

One more thing

Asked locally

Sacramento gardening questions

3
Is it safe to plant okra and sweet corn now in Sacramento?

Yes, the ground is warm enough for both, but ensure you get seeds into the soil before tonight's potential rain event. Okra thrives in our heat once established, while corn needs consistent moisture during germination.

My watermelon vines are growing fast; when should I start harvesting?

Begin checking for harvest maturity within 7 to 10 days if the fruit develops a creamy yellow slip at the stem end. In Sacramento's current heat, maturation happens quickly, so don't wait until they turn fully black on the skin.

Should I be concerned about frost damage to my garlic crop right now?

No immediate concern; with an average last frost date of January 30th, your hardy garlic is well past its danger zone. Focus instead on thinning if shoots are overcrowding to ensure proper bulb size.
