Frequently Asked Questions About Seeds and Gardening
When should I plant vegetables in Berkeley?
Berkeley's mild climate allows year-round gardening. Cool-season crops such as lettuce, peas, kale, and carrots grow well from fall through spring. Warm-season crops like tomatoes, peppers, beans, and squash are typically planted in spring after the soil warms. Microclimates vary between the flats and the hills, so local experience and observation are valuable.
What is the difference between heirloom and hybrid seeds?
Heirloom seeds are open-pollinated varieties passed down over generations, and seeds saved from them grow true to type. Hybrid seeds are created by crossing two parent varieties to achieve specific traits like disease resistance or uniformity, but saved seeds from hybrids may not reproduce the same characteristics. Both have advantages depending on your goals.
How do seed libraries work?
Seed libraries let members take seeds for free or at low cost, grow plants, and return some saved seeds at the end of the season. This process builds a collection of locally adapted varieties and encourages seed-saving skills within the community.
Why plant California native species?
Native plants are adapted to local climate and soil, require less water once established, and provide habitat for pollinators, birds, and beneficial insects. They help create resilient gardens that connect urban spaces with regional ecosystems.
How should I store leftover seeds?
Keep seeds in a cool, dry, dark place in sealed envelopes or jars. Properly stored seeds of many crops remain viable for several years.
