San Francisco Backyard Gardening: How to Start with Vegetables, Flowers, Fruits, and Herbs at Home in California

Some individuals garden to detach from the world and concentrate on themselves. Because of this, we’d want to get the word out about it. These are advantages that we believe you should enjoy as well. To get the most out of your new pastime, you should choose something that is both enjoyable and useful. Growing plants is a hobby—millions of people like growing plants in their backyard as a peaceful pastime. 

Below you will learn about the San Francisco backyard gardening guide, the San Francisco vegetable garden in the backyard, the climate and planting zones of San Francisco, when to start planting in San Francisco, and how to grow different fruits, vegetables, flowers, and herbs in the backyards of San Francisco and a detailed step by step guide to growing a backyard garden in San Francisco.

About the climate and USDA hardiness zones of San Francisco, California

Hardiness Zone 10 is where San Francisco, California, can be found. The timing of planting seeds and transplants is crucial for a successful garden. You can sow your plant seeds at the appropriate time of year if you know your first and final frost dates. There are a staggering 270 days between the last frost and the date of the first frost of the season in California, making it an ideal location for growing plants. 

As California lies in the north, its USDA Hardiness Zones range from 5 to 10. Because of this, the optimal time to grow certain plants in southern California can differ from the optimal time to plant those same plants in northern California. This implies that some crops may be planted at a specific period in southern California. The earliest day of frost for San Francisco is on December 15th, and the final date of frost is February 1st.

San Francisco’s climate is characteristic of California’s coast: Mediterranean. This climate is characterized by wet and moderate winters and dry summers. The warm currents of the Pacific Ocean, located on the city’s western side, and the water of San Francisco Bay, located on the city’s northern and eastern sides, significantly impact the city’s climate. This results in a fairly mild environment that remains consistent throughout the year and has minimal temperature variance from season to season.

Compared to other major cities in the United States, San Francisco experiences the lowest average, highest, and lowest daily temperatures during June, July, and August. During the summer, rising hot air in the interior valleys of California forms a low-pressure system that attracts winds from the North Pacific High through the Golden Gate. These winds are responsible for the cold breezes and fog that are distinctive of the city.

In the east, fog is thinner than typical in late July and early October. As a direct consequence, September is, on average, the hottest month of the year, while October is, on average, warmer than July, particularly during the afternoon. On average, only 21 and 23 days per year, temperatures reach or surpass 80 degrees Fahrenheit (27 degrees Celsius) in downtown San Francisco and at San Francisco International Airport (SFO), respectively.

The dry season, which lasts from May until October, features mild to warm temperatures, with September recording the highest average monthly mean temperature of 62.7 degrees Fahrenheit (17.1˚C). The normal monthly mean temperature drops to its lowest point of 51.3 degrees Fahrenheit (10.7 ˚C) in January during the wet season, which lasts from November to April. The average annual rainfall is 23.65 inches, with 73 rainy days (601 mm). There is a significant change in the amount of precipitation from one year to the next.

Choose the right location for your backyard garden 

Several considerations must be made when looking for the ideal backyard garden location. The best spot for your garden receives 6 to 8 hours of direct sunlight daily. There is a direct correlation between the quantity of sun received and the yield. Gardens started in partial shadow fare badly. Thus it is best to avoid establishing them near giant trees or in situations where the tree’s roots would compete with those of the plants for moisture and nutrients.

The yield may or may not be affected by the shade cast by buildings, fences, and other structures, depending on the situation’s specifics. While it is best to locate a backyard garden on a level plane, the ground does not have to be completely level. On the other hand, steep slopes may need terracing to minimize soil erosion during periods of high precipitation. Locations that protect from persistently high winds are ideal for growing plants.

When strong winds knock over plants, their leaves might wilt and die because the moisture in the soil is lost. When spring and autumn come around, plants on the northern side of the garden will benefit from the protection that windbreaks provide from the cold. Plants need 1 inch of rain or watering every week. Because of this, the garden has to have an easily accessible water supply. Ultimately, deciding where to put the backyard garden can include balancing a few competing priorities.

Start preparing the soil for your backyard

The first stage in starting a garden is preparing the site since the soil’s quality determines the project’s success. It is necessary to remove any existing vegetation before beginning the amending and tilling of the soil, followed by fertilization and amendment. After the location has been chosen, the previous vegetation will need to be cleared away. Depending on the kind of plant, a different set of techniques may be required. Hand-pulling or turning beneath weeds with a shovel are two standard methods.

Remove the top layer of soil, which includes grass and roots, using a sharp spade. The compost pile can then be used for these. Smothering the whole area is an effective method for getting rid of perennial weeds, including nutgrass, bindweed, and bermudagrass. Solarization and sheet composting are two techniques for smothering. Covering the surface with 2 to 4 mil UV-resistant translucent plastic, polyethylene, or polyvinyl chloride sheeting, is the first step in solarization.

A minimum of six inches of moist earth should be pushed into the foundation before planting. To raise the soil temperature sufficiently, white or black plastic will not transmit enough light (transformed into heat). The plastic should remain in place for anything between four and eight weeks. Layering organic materials such as leaves, grass clippings, and manure to a depth of twenty-four inches or more is called “sheet composting.” This method essentially turns the whole area into one big heap for composting.

After composting for some time, it is time to transform it into the soil and begin planting. A year is not uncommon for sheet composting. Perennial weeds can be challenging to manage in the growing season if they are not eradicated. For a plant to thrive, it needs 16 components from the soil. Air and water are the primary carbon, hydrogen, and oxygen sources. Macronutrients include nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca), all of which are consumed in high quantities.

These nutrients are primarily obtained from the soil and, when insufficient, must be supplemented with fertilizer additives. Because they are consumed in lower amounts, the other elements are classified as secondary or micronutrients. The soil pH, organic matter percentage, and accessible phosphorus, potassium, calcium, and magnesium levels may be adequate for plant development.

A regular soil test will provide these values and advice for addressing shortfalls. Typically, soil tests do not include nitrogen levels since this element is very water-soluble and must be replenished yearly. A standard fertilizer application is two to three pounds of nitrogen per 100 square feet of backyard garden space. Before planting in the spring, fertilizers should be thoroughly integrated into the soil.

Correcting soil shortages or imbalances with fertilizers and organic matter and improving its texture will produce an ideal environment for root growth. The most significant time to prepare the soil for spring planting is in autumn. Plants thrive on soil with high humus content. The decomposing organic matter eventually yields humus, the most stable form. Humus improves drainage in heavy clay soils, while moisture retention is improved in sandy soils.

Use a shovel or tiller to add ten inches of organic materials, such as compost, leaves, grass clippings, or aged manure. If the soil is excessively wet, avoid working it. If you can form a ball of soil in your hand and it crumbles easily, you can work the soil. Use only well-composted materials when enriching the soil before planting in the spring.

Plant your backyard garden 

The timing and method of planting your plants can significantly impact the outcome of your garden. The hardiness of the plants and the environment in your location determine how early you can plant. Frost doesn’t affect all plants equally. Tender, hardy, and extremely hardy are the four main plant classifications. When it comes to planting seeds or young plants, there is neither a magic trick nor a complicated skill involved. Follow these instructions for seed starting in the garden:

Soil Preparation

Disease-free seeds are recommended. Lay out your garden in rows to make it more aesthetically pleasing and to help with growth, pest control, and harvesting. Two pegs should be driven into the ground at either end of the garden, and a string should be drawn between them. To make shallow furrows ideal for tiny seeds, just follow the string’s direction with the handle of a hoe.

Wheel hoes and corners of hoe blades work well for digging down into the soil for deeper ruts and holes. Ensure that the distances between the rows are correctly spaced. Drill or hill the seed. The term “hilling” refers to the practice of planting many seeds at regular intervals along a row. It’s common to grow sweet corn, squash, melons, and cucumbers in this fashion.

Weeds can be more easily controlled between the hills of plants thanks to hilling. Most seeds are planted by “drilling,” which involves spreading them uniformly along a row with a drill or by hand. Sow seeds evenly spaced down the row. Spread the seeds out evenly. Sometimes, it’s easier to scatter little seeds if they’ve been combined with dry, crushed soil beforehand. A decent rule of thumb is to sow the seed four times its diameter.

Apply one inch of soil to tiny seeds like carrots and lettuce. Large seeds like maize, beans, and peas should be planted 1 to 2 inches below the surface. Plant the seeds a little deeper if the soil is sandy or there is a lot of wind in the forecast. Seeds need to be protected and the soil firmed up. Using your hands or an upright hoe, gently press the soil around the seeds. This keeps the seeds from being washed away by rain.

When the plants are young, thin them to a desired number of plants and remove the weakest bushes. Consider the consequences of overcrowding before it’s too late. Alternatively, you can use transplants to get started. If possible, do the procedure on an overcast day or late at night. Keep an eye on your plants at all times. A few hours before transplanting, properly hydrate the plants and soil (pots, bands, etc.).

To extract the most soil from each root, block out the roots of plants in flats with a knife. Plants should be removed with care so as not to disrupt the roots. Keep a soil ball around the roots at all times. When the roots aren’t in the soil, they must be kept wet. Remember your pot size and dig a hole of the same size. Unless you’re growing tall, spindly tomato plants, this rule applies. You can plant it in the hole.

When the stem is covered with soil, roots will grow along it. Try using a starter solution help plants get started to quick start. Use one tablespoon of a phosphorus-rich all-soluble fertilizer (1-52-17 or 10-50-10) per gallon of water. Each plant should have roughly a cup of the solution placed around its roots when transplanted. If needed, apply extra soil around the roots.

If required, protect plants from extremes of temperature, wind, or cold. If you’re concerned about spring frost, there’s the option of using paper or plastic plant covers. Various containers may be used to make homemade planters, including baskets, boxes, and jars. Don’t keep the plant protection on for longer than it’s needed. Remove or open the plant protector if it becomes too hot throughout the day to keep the plants from overheating.

Start watering your backyard garden

It is impossible to grow high-quality crops without sufficient water. Even while rain is a fantastic water supply, there will likely be times throughout the growing season when there is little to no precipitation, and you will need to water your garden. It is essential to carry out the steps in the correct manner. During dry months, plants should be watered once a week. Preventing diseases is easier if you water your plants early in the day before the morning dew has a chance to settle on them.

Watering in Garden

Instead of simply watering the garden at numerous intervals, you should thoroughly saturate the soil to a depth of at least 15 centimeters (at least 6 inches). The water needs to reach the lower parts of the plant, where the roots are located. Plants should get around one inch of water each week, including precipitation. Put four or five cans in the area being watered so you can accurately quantify the quantity you are applying. They will gather an amount of water equivalent to that of the soil.

Fertilize your backyard garden 

Both organic and inorganic kinds of fertilizers are available. Organic fertilizers are produced from the decomposing matter of plants and animals. These materials have a gradual release rate for nutrients, which lessens the likelihood of fertilizer burn and the number of times it must be applied. Microorganisms in the soil are responsible for converting organic nutrients into an inorganic state, which is then required for plant uptake.

The use of organic fertilizers in the autumn is recommended for several reasons, one of which is to provide sufficient time for the breakdown of organic matter and the release of nutrients so that plants can utilize them earlier in the growing season. Inorganic fertilizers are those that are produced using non-living substances. Mineral deposits might sometimes hold the answers you’re looking for. However, the vast majority are manufactured by a series of chemical processes.

Most inorganic fertilizers include water-soluble nutrients and are, as a result, easily accessible upon application. These can be sprayed throughout the growing season so plants can immediately absorb them. This benefits plants that need a rapid feed to create fruit and presents an advantage to plants grown in warmer climates. Raised beds may be needed if the soil can’t be amended or if there’s just a thin covering.

This allows for the garden to be developed despite these conditions. It is possible to make raised beds of any size using different construction materials, including wood, plastic lumber, brick, stone, etc. Alternately, one may build a raised bed by piling the earth up in a mound without constructing any structural sides. Stay away from timber that has been treated. The raised beds’ depth must be at least twelve inches to provide sufficient soil for root growth. 

There are positive and negative aspects to consider while using raised beds. They warm up more quickly in the spring, allowing planting to begin sooner and increasing drainage. Due to better drainage, raised beds to require more watering, especially in the summer. Additionally, the soil will need to be brought in while making raised beds. Most often, raised beds are used when the subsoils are of low quality and continue to impede plant development after significant amendment.

When to start planting in San Francisco, California?

Southern California’s climate and the method of planting vegetables have a role in deciding the best time to plant. Gardeners who wish to grow their crops in the ground will have to wait several weeks before planting their seeds inside. In addition, the gardener who planted the seeds will have to wait longer for their harvest if another person plants seedlings outdoors on the same day.

If you want to produce lettuce, celery, peppers, chard, tomatoes, radishes, spinach, eggplant, kale, or broccoli, you should start your seeds inside in January for a mid-to late-spring harvest. Beets, cauliflower, and cabbage may also be started inside in January. Starting in February is OK if you’ve had your last frost. Seeds can be planted in the ground, transplanted from a local nursery, or seedlings grown inside in January can be transplanted into the garden.

You can start seeds for carrots, cucumbers, pumpkins, kale, lettuces, cantaloupe, zucchini, and onions indoors if you haven’t had your last frost yet. Carrots, radishes, cauliflower, lettuces, cabbage, broccoli, kale, and chard are all ideal vegetables to put in your garden right now. Make sure to sow your seeds in March if you want to grow pumpkins for Halloween. This is also the time when most gardeners may start seedlings or transplants.

To start seeds inside, you can try to grow cucumbers, Brussel sprouts, or squash. If you’re growing outside, you may plant tomatoes, carrots, beets, lettuces, peppers, cauliflower, celery, spinach, cucumbers, maize, and watermelons this month. If you haven’t begun your Halloween pumpkins in March, here is your final opportunity to start them as soon as possible in early April. Squashes, cucumbers, cantaloupe, beans, watermelons, eggplants, carrots, and peppers are some other fruits and veggies you can grow in April.

Try to plant at the beginning of each month, if possible. Some of the crops you grew earlier this year will be ready for harvest as the season progresses near the end of spring. Another option is to grow cantaloupe, maize, cucumber, beans, beets, squashes, peppers, chard, and kale. Your garden can be too warm and too late to grow most food crops at this point in the season. You should be reaping the benefits of some of your previous plantings at this point.

This month is still a good time to grow certain veggies in your gardens, such as zucchini, peppers, beans, and corn, although it’s getting late in the year. July is an excellent time to sow beans and squashes. Plants like peppers and tomatoes can be transplanted now and should grow just fine. This month is all about monitoring soil moisture and savoring the results of your effort.

You may begin planting your second batch of food plants in August for a late autumn or winter harvest. It’s ideal for expanding towards the end of the month. Tomatoes and peppers can be planted year-round. Cucumbers, celery, beans, and zucchini may also be started. Carrot planting can be resumed in September. Planting celery or starting seeds for various vegetables, including beets, beans, and cauliflower, is also a smart idea at this time of year.

It’s time to start your autumn and winter gardens now that the weather is cooling. It’s a good time to grow a wide variety of vegetables such as beans and peas and a wide variety of herbs like basil and thyme. It’s a fantastic time to plant fruit trees in your garden if you haven’t already. An excellent time to grow lettuce, carrots, turnips, and spinach in November is if you don’t anticipate a frost or freeze in your location.

You can also plant garlic and beans if you’re not anticipating one. Fruit plants may be planted now as well. When it comes to Southern California gardening, December is the year to grow lettuce, kale, radishes, broccoli, cabbage, spinach, turnip beets, leeks, parsnips, and chard in places with mild temperate conditions.
