    1. Cool Season vegetablesWhat is exciting to grow UCCE Master Gardener Program of Santa Clara County 2013

    2. Master Gardeners of Santa Clara County • Master Gardeners of Santa Clara County Mission is to extend research-based horticultural information to home gardeners. We are a UC program, through UCCE. • Telephone and walk-in Hotlines in San Jose and Palo Alto • Demonstration Gardens in Sunnyvale and Palo Alto • Free workshops and classes • Adult Education two-, three- or six-week courses • Monthly Tips & Events email • More than a dozen active projects throughout the county • Daily Facebook posts of “what’s in bloom,” tips, talks • Gardening information and guided search tools on our website:

    3. Overview • Quick review of soil and planting • What vegetables we grow, discussion of varities • Questions

    4. What is needed • Sunlight and warmth • Properly prepared soil • Irrigation (and compost as mulch) • Plants from transplants or seeds • Control pests • Harvest

    5. Know Your Sun • Where do you get the most sun during the year? In the winter? • Where do you get shade, year-round? • Put trellises and cages on the north side. • Maximize your sun to get the best out of cool season.

    6. Soil amendments • Compost is not fertilizer BUT improves soil structure … what does that mean? • Do add nitrogen for vegetable beds. What are sources of organic nitrogen? • Also … over-fertilization  Plants need more water and grow faster and bigger  You need to prune a lot! And pests love that fresh flush of new succulent growth!

    7. How & When to Water • Deep watering means “slow and long”—check with finger or moisture meter • Why is hand-watering hard to do? • Factors affecting irrigation • Soil water holding capacity • Water infiltration rate • Depth of rooting • Irrigation method and output

    8. Watering Your Vegetables - Best Practices • When are you watering? • How many days a week? • For how long? • Swampy or dry spots? • Overhead or drip? • What is this handy tool?

    9. Why start from seed? • Get an early start on the season • Start plants that are difficult to find • Good for hard-to-germinate seeds • Plants do not have transplant shock when direct seeded • Try comparing starting from seed and transplanting the same plant—you might find the ones started from seed do best

    10. Why use transplants? • You do not need such an early start on the season • Plants are already ready to go • You can decide on your garden when you are buying the plants • You don’t have to fuss over seeds • Find varieties that suit our area (hopefully) • Shorter time to harvest

    11. How to choose plants? • Look for healthy-looking plants • Check to see if pot bound or has underdeveloped roots • Try to get a plant that is not yet in bloom and if so remove the blooms • Better off with plants in smaller containers • Now you can plant as soon as possible

    12. How to select healthy plants Pot bound or poor root systems plants Example of developed and underdeveloped root systems. Source:

    14. Plan for year-round harvest • SPRING To harvest in April and May: Start seeds in January/February to plant in March/early April • SUMMER: To harvest from June-September, start seeds from March/April to plant in May/June, for June-September harvest • FALL/WINTER: To harvest from Nov-Feb, start seeds from August-September, to plant in September/October. If you have room, direct seed in August. • PLANT (ALMOST) ANY TIME: many greens, such as lettuce, chard, kale, collards, spinach.
