Central Sierra: Vegetable Gardening Basics in Lake Tahoe

The Basics of Growing Edible Crops in Tahoe

Overcome Challenges

A Short Window: The average frost-free growing season is only about 93 days.

The frost-free window typically runs from June 18 to September 19. This is unpredictable! Freezing temperatures can occur any night of the year, and snow is possible in any month.

Tahoe Soil Properties: Local soil is primarily decomposed granite. Food gardening requires soil amended with about 6 inches of organic compost. Many food gardeners in Tahoe have better success with raised beds.

Plan a planting sequence

For all types of edibles, choose high-altitude varieties with a shorter number of days to maturity.

In spring you can plant "Cold Crops". These are hardy plants like arugula, chard, kale, broccoli, and spinach which can handle light Tahoe snow.

After the risk of frost is minimal, set out your "Warm Crops". Warm season vegetables such as beans, peppers, squash, and tomatoes should be reserved for the warmest months: June, July, and August.

In the early fall (September), you can sow another round of the spring crops, and plant your garlic bulbs. With some frost protection as fall sets in, you will have another harvest of cold crops, perhaps even until Thanksgiving!

Follow These Tips for Growing Success

Most herbs and veggies should be started indoors 6–10 weeks before the last frost. Heat mats, humidity domes, and grow lights are helpful.

Root crops like carrots, radishes, and beets should be sown directly because they do not like their roots disturbed. Large seeds such as peas and beans are also more successful directly sown where they will grow.

Combat Pests and Bad Weather

Hardening Off: Transition indoor sown plants outdoors slowly over about 7 days; and bring them in at night. After a few days, you can leave them out overnight but only if temperatures stay above 40°F.

Temporary blocks like buckets or boards help prevent "wind burn" on tender leaves.

Use frost cloths, cold frames, or hoops to protect warm-weather crops.

Physical barriers and hardware cloth help manage rodents and larger animals.

For aphids or mites, use water sprays, Neem oil, or beneficial insects like ladybugs.

Protect the Tahoe Watershed

To protect Lake Tahoe's clarity, use chemical fertilizers with no phosphorus. Do not fertilize right before a rain storm.

Watch your garden as it is irrigated for runoff and create wells or mounds to prevent water from leaving the garden to control erosion.
