Purple zinnias with summer veggies, David Giroux
The top 4 things to remember for a successful vegetable garden are:

  1. Choose a sunny location. Most vegetables need at least 6–8 hours of sun. Some leafy greens and root vegetables can take a little shade, but most (tomatoes, peppers, etc.) need full sun.
  2. Prepare the soil well. Thoroughly remove all weeds, dig to loosen the soil, and amend with compost and fertilizer as needed.
  3. Plant vegetables at the right time. See our Vegetable Planting Chart to choose the right vegetables for the time and season.
  4. Keep vegetables well watered. Seedlings may need extra to get established. Don't overwater, but be sure give them enough so they grow well and are productive.

See Vegetable Garden Basics for more details. For information on a specific vegetable, check the individual vegetable pages listed below.

When to plant

Here in Santa Clara County we can grow vegetables year round. Our Vegetable Planting Chart gives month-by-month planting times for warm and cool season vegetables to help you make full use of your vegetable garden. The chart includes when to transplant seedlings, when to plant seeds directly in the ground, and when to start seeds if you are growing your own transplants.

Warm season vegetables

These are vegetables that grow best in the summer (April–September) and generally can't tolerate temperatures below about 50° F. Perennial vegetables that produce in the summer are included here.


Cool season vegetables

These are vegetables that grow best in the fall, winter, and early spring (September–April). Some of these can be grown in the summer as well, with some care.


If there isn't page yet for a vegetable you are interested in, try the California Garden Web site or contact our Help Desk for advice.
