Growing vegetables at home can be done in a single pot on your patio or on a larger scale depending upon the space and time you have available.
Good planning and preparation will reduce the workload in your garden. For example, if you install a drip system that can accommodate all of your beds, you will never have to drag an irrigation hose around. If you apply a heavy layer of course mulch between the beds, your weeding will be minimal. If you build raised beds, your garden will be more organized and less likely to degrade to weeds.
Knowing your planting zone is critical. In the counties of Humboldt and Del Norte according to Western Sunset Garden Book there are 6. Both counties' Maritime zones are 17. Humboldt's Coastal zones are 14 and 15 depending on your location. Other zones in various areas of Humboldt are 4, 7 and 1a. Del Norte's various areas include 7 and 1a. Look at Sunset Zone Map to determine your Zone.
Planting Calendar by Zone
Cool season vegetables grow best and produce the best quality crops when average temperatures are 55-75o F. They usually tolerate slight frost when mature. Some crops can be grown year round in parts of Humboldt and Del Norte Counties. Cool Season Planting Calendar
Warm season vegetables require long, hot days and warm soil to mature. They grow best and produce the best quality crops when average temperatures are 65-95o F. They are intolerant of prolong freezing temperatures. Depending on your zone and your own microclimate Tomatoes and peppers are difficult to grow except in a greenhouse environment.

SOIL, COMPOSTING AND FERTILIZERS
Know your Soil (EHN 55)Soils vary greatly from one place to another. Some are ideal–they are deep, easily worked, and fertile. Many have physical or chemical limitations–they are too shallow, too sandy, too clayey, too steep, or too low in fertility. Some are too salty or contain other chemicals that are toxic to plants. On the other hand, there are very few places where good gardens and landscape plantings cannot be grown. The secret is to know the nature of the soil, the kinds of problems to expect, and what can be done about them.

Gardening on Hardpan Soils (EHN 53) Hardpan soils are noted for the problems they present. However, if the nature of the soil is understood the problems can usually be overcome.
Sheet Mulching (EHN 94) Sheet Mulching is a layered mulch system. It is a simple and underutilized technique for optimizing the benefits of mulch.

Attracting Beneficial Insects (GN 129)
Attracting Native Pollinators (GN 156) Birds, bats, bees, butterflies, beetles, and other small mammals that pollinate plants are responsible for bringing us one out of every three bites of food. They also sustain our ecosystems and produce our natural resources by helping plants reproduce. Unfortunately they are in trouble. Some species have seen a 90% decline in their populations over the last decade. But you can help. There are a number of ways you can enhance your garden to be more pollinator-friendly.
