Santa Clara County Vegetable Planting Chart

UC Master Gardener chart for central Santa Clara County seeding, transplanting, borderline months, and warm/cool seasons.

Climate signals

• The UC Master Gardeners of Santa Clara County chart gives recommended times to plant vegetables in Santa Clara County.
• Use the chart as a guideline because its dates are for best results on average in central Santa Clara County.
• The best planting times can vary by location in the county, microclimate conditions, and weather in any given year.
• Pale green squares mark borderline months that might work, not normal planting windows.
• The Santa Clara County vegetable hub says vegetables can be grown year round in the county.
• Warm season vegetables are framed as April to September crops that generally cannot tolerate temperatures below about 50F.
• Cool season vegetables are framed as September to April crops, with some able to grow in summer with care.

Planning notes

• Use the chart's transplanting and direct seeding methods separately; do not merge them into one planting window.
• Use the From seed to transplant column to count backward from transplant timing; the source example starts broccoli for a mid-September transplant about 6 weeks earlier, around August 1.
• Harvest times are not included because they vary widely by variety and season, and crops mature more slowly in the cool fall/winter season than in the warm spring/summer season.
• Artichoke, Arugula, Basil, Beans, Beets, Bok choy, Broccoli, Brussels sprouts, Cabbage, Carrots, Cauliflower, Celery, Chard, Cilantro, Collards, Corn, Cucumber, Daikon, Dill, Eggplant, Fennel, Kale, Kohlrabi, Leeks, Lettuce, Mache, Melons, Mustard greens, Okra, Green onions, Parsley, Parsnips, Peas, Peppers, Pumpkins, Radishes, Rutabagas, Spinach, Winter squash, Tomatoes, Turnips, and Watermelons have conservative crop-row catalog examples.
• Asparagus crowns, Belgian endive, bitter melon, chayote, fava beans, gailon, garlic, bulb onions, luffa, Napa cabbage, potatoes, summer squash, sweet potatoes, and zucchini are source rows without priority links.
• Use priority catalog links as crop-row examples, not UC cultivar recommendations.
