Planning your Spring Garden Now Will Pay Dividends Later

Developing a Garden Plan
A good way to lift the spirits and put you in a spring mood is to start planning your spring garden. Not only is it good for your state of mind, but will pay many dividends on creating a successful spring and summer growing season.

Take an Inventory of the Plants You Have and Their Locations

Planning a spring garden begins with taking an inventory of the plants you have and the areas of your garden you like and which areas you would like to change. Are there plants that should be relocated so they perform better or areas you would like to add more color? These are just a few of the basic questions which together will form the basis of a garden plan. It is always a good idea to sketch out a rough picture of your yard and mark the areas that have different sun exposures. Mark the areas that get full sun, partial shade, and full shade along with special areas marked such as where the vegetable and herb garden will be located or a flower cutting garden.

Review Success and Failures from Past Year

It is important when planning your spring garden to review your garden successes and failures from the previous year. What vegetables and flowers seemed to thrive with very little effort and which ones required more care or had issues such as not growing well or insect and disease issues. If you keep a garden journal this is an opportunity to review your entries from last year. If you do not keep a journal, now is the time to start and keep all of your garden notes as you plan out your garden.

If you use containers to grow flowers or vegetables, review which plants did well in containers and which did not. Container planting can put stress on plants if the soil temperature gets too hot in the sun, the pots are not sufficiently watered, or if salts build up in the soil from hard water and over-fertilization.

When reviewing plants that you did not have success with but still want to try again this spring, think about what factors need to be changed. Doing a little research is always a good idea to determine, for example, what are the ideal light, moisture, soil, and pH requirements as well as frost hardiness for perennials. Several excellent sources for researching information on plants include:

For California Native Plants an excellent source for developing lists of plants meeting various criteria and detailed information on the plants – Calscapes Native Plant Guide.

Getting Ideas and Inspiration

If you are looking for inspiration on what to plant that you may not have tried before, a good place to start for inspiration is your neighborhood. What plants in your neighborhood have caught your eye? If you are not sure of the name of a plant, it is a good opportunity to touch base with your neighbor and learn more about successes and failures in their garden. My experience is that neighbors and friends love to talk about their gardens and I have personally had several tours of our neighbors’ gardens.

Another source of inspiration is to think about plant families. If you like a particular flower, think about planting other varieties from the same plant family. This will give you some additional variety in your garden and increase the chances of being successful since you already have had success with a member of the same plant family. For example, if you have had success with African daisieswhich is a member of the large plant family Asteraceae, you might consider other members of the family such as cosmos, sunflowers, asters, dahlias, marigolds, or chrysanthemums for example. As with any plant you are considering, you should research their light requirements and any of the other factors that will help you find the appropriate spot in your yard.

For plants that have a history of success in the Bay Area, the Alameda County Outstanding Plants brochures will provide many ideas on plants that have been tested and proven successful in Alameda County.

Also, an invaluable resource is the Calscape Garden Planner. With 4 simple questions about where you live, the type and goals of the garden you desire, and how much sun your yard gets, Calscapes garden planner will identify trees, shrubs, herbs, and flowers that meet your requirements and will perform well in your particular area.

Lastly, wherever you live in Alameda County, you are not too far away from one of the Master Gardener Demonstration gardens found in Albany, Hayward, Oakland (Lake Merritt), Livermore, and Fremont (Quarry Lakes). You will find many examples of plants that grow well in the Bay Area climate and can provide more color and beneficial insects to your garden. Here is a link to where you can find the locations and more information about these demonstration gardens:

Seed Starting

After you have planned out your garden enough to know what you want to plant, consider starting plants from seed where possible. Why start seeds yourself? By starting seeds now, you will have plants ready to plant in the ground in early to mid-Spring. In addition, you will save money since a seed packet is less expensive than buying starter plants and contains many more possible plants. 

By choosing to start your plants from seeds, you have more choices, particularly varieties that are not available as starter plants in nurseries.

A typical seed package will last several years and produce many plants, enough to pass around to your friends and neighbors. It is a great way to build goodwill with your neighbors and promote growing your own vegetables and flowers.

Another benefit is that starting your plants from seed is a wonderful educational experience for children. It is an early opportunity to teach children valuable life lessons such as the joy and beauty of nature, nurturing plants, and developing patience. Seed starting can be a family activity and an opportunity to talk about the broader world of gardening and its benefits.

 Vegetables that are typically started indoors include tomatoes, peppers, herbs, lettuces, Asian greens, broccoli, cauliflower, cucumbers, and summer squash. Seeds that are typically started in the ground when the soil warms up include beans, beets, carrots, chard, peas, potatoes, and turnips. Here is a useful planting chart on when to plant vegetables indoors and when to put seedlings outdoors by month and vegetable type:

Many flowers such as marigolds, cosmos, aster, hollyhocks, salvias, and nasturtiums to name a few, are easy to start indoors and you will be able to grow larger trays of these flowers than you might easily purchase in a garden store. To help your planning, review this useful chart about which flowers can be started indoors and which should be started outdoors

To germinate, seeds need water, oxygen, an appropriate soil temperature, and, in some cases, light. For good drainage in containers, plant seeds in a commercial seed-starting mix. If you are planting the seeds outside, make sure your soil is loose and well aerated.

One aspect of planting from seed that is often under-appreciated is soil temperature. Having the right soil temperature can make the difference between seeds not germinating at all if the soil is too cold, or taking weeks to germinate when a warmer soil temperature will make the seeds germinate much faster.
