One of the most common misconceptions about spring gardening is that everything should be planted at once in March or April.
In reality, spring planting in Southern California stretches well into summer. Because our climate stays warm for so long, many crops actually perform better when planted later in the season.
We also need to factor in our coastal weather pattern of May Gray and June Gloom, when cool cloudy conditions can slow growth and increase disease pressure on certain plants, especially those susceptible to powdery mildew.
The key is planting crops according to their temperature preferences.
Early Spring Planting (March – April)
These crops tolerate cooler soil and mild spring temperatures and can be planted earlier in the season.
Herbs
- Basil (late March/April)
- Cilantro
- Parsley
- Chives
- Oregano
- Thyme
- Sage
- Marjoram
Early Warm Season Crops
- Tomatoes
- Bush Beans
- Pole Beans
Tomatoes benefit from getting established early because they require a longer growing season to produce heavily. Beans germinate quickly and grow well in mild spring temperatures.
Late Spring / Early Summer Planting (May – June)
These plants prefer warmer soil and nighttime temperatures. Planting them too early can slow growth and increase the chance of disease.
Heat-Loving Crops
- Peppers
- Eggplant
- Zucchini
- Summer Squash
- Cucumbers
- Melons
- Pumpkins
- Winter Squash
- Okra
- Sweet Potatoes
Waiting until May or early June helps these plants avoid cooler coastal conditions and reduces the risk of powdery mildew during early growth.

Color & Pollinator Plants (Edible Flowers)
Adding edible flowers brings beautiful color to the garden while also supporting pollinators that help increase fruit production.

- Nasturtiums
- Calendula
- Borage
- Sunflowers
- Chamomile
- Viola / Pansies
These plants attract bees, butterflies, and beneficial insects while also serving as edible additions to salads and garnishes.
Watering as Temperatures Rise
Because we’ve experienced very little winter rainfall, our soils are entering the warm season much drier than normal. As temperatures rise, soil can dry out extremely quickly.
Healthy gardens depend on deep and consistent watering.
Watering Tips
- Water deeply so roots grow downward
- Water thoroughly rather than frequent shallow watering
- Add compost and mulch to retain soil moisture
- Check irrigation systems regularly
- Deep watering encourages stronger plants and healthier soil biology, helping gardens better withstand our long, hot San Diego summers.
