California is a state of many climates. Seed scheduling that works in Monterey will not work in Bakersfield or Palm Springs. A greenhouse gives you control over temperature, humidity, and frost protection, but you still need to match seed-start timing to local climate, crop biology, and the greenhouse capabilities (heated vs. unheated, vented vs. sealed). […]
California growers who use greenhouses have a powerful advantage: control. Even so, pests like aphids, whiteflies, spider mites, thrips, and fungus gnats find their way into controlled environments. Choosing herbs that are naturally pest-resistant reduces intervention, lowers pesticide use, preserves beneficial insects, and makes small-scale and commercial systems more reliable. This guide identifies the best […]
Converting a backyard shed into a mini California greenhouse is an efficient, cost-effective way to extend your growing season, start seedlings earlier, and protect tender plants from weather extremes.
