VEGETABLES
your home; healthy, rock- and weed-free soil (add compost if needed); and a minimum of eight to 10 hours of sunlight in the summer and six to eight hours in the winter. The garden can be inground, a raised bed or a container. Observe the site during daytime hours, making note of where and when the shadows appear. Windy areas, walls and fences, and slopes create their own weather called “microclimates,” which can influence how well the plants grow. Study the microclimatic conditions of the site before planting.
Vegetables are categorized as either “cool season” or “warm season.” In Southern California, cool season vegetables grow best from September through April and warm season vegetables thrive from March to October. Cool season vegetables include broccoli,
cauliflower, peas, short-day onions, and both root and leafy vegetables. Warm season vegetables are tomatoes, cucumbers, melons, peppers, beans, corn and eggplants. Select plants appropriate for the season for best results. For a complete list of cool and warm season vegetables for San Diego County, look at the Master Gardener Vegetable Growing Guides at www.mastergardenersd.org/ growing-guides.
Once you’ve decided what to grow, plan where to place the plants by creating a planting plan and record. First, figure out how much space a mature plant needs. Then roughly sketch your planting area and plot the space for each mature plant. By doing this, the garden will not be overplanted and each vegetable will have enough space to reach maturity.
Next, make a list of each plant (type and variety such as “watermelon, Sugar Baby”), the date planted, expected harvest date
and a space for notes. This record will help you remember what was grown, what grew well and what you liked. Another option is to use a smartphone garden journaling app. A sample planting record is available on the Master Gardener website at www.mastergardenersd.org/beginning-vegetablegardening.
Lastly, create plant labels or tags for each type of plant to identify them in the garden.
To begin planting, gather the needed supplies such as trowels, shovels, gloves, seeds or transplants (starts), vegetable fertilizer or other fertilizer high in nitrogen and phosphorus, and soil if planting in containers. To plant transplants, begin by digging a hole to the depth of the plant’s root ball and twice as wide. Add a small amount of fertilizer in the hole and mix with existing soil. Gently remove the plant by turning the pot at a downward angle, place your hand across the open end with the
stem between two fingers. Apply pressure to the bottom of the pot by squeezing or tapping. Ease the plant out. Never pull the plant by the stem. Place the plant in the hole, level with the ground, and fill with existing soil, and tap down to make it firm. Do this for each plant and then water until the soil is moist to a depth of 2 inches.
Seeds can be direct-sown into the soil or started in a disinfected container (with drainage holes) using a moist, sterile, seed-starting media. Some vegetables such as beans, beets, corn, carrots and arugula are best when direct-sown while others such as tomatoes, broccoli, cabbage and peppers do better when started indoors in a container. Follow the seed package instructions for depth, spacing and any special instructions. The seed package also has information on mature size and time to harvest. Instructions on starting seeds indoors and transitioning them to outdoors can be found at this link:

Water the young plants, keeping the soil moist but not wet, to a depth of at least 2 inches. Initially, this may be every day or every other day. Fertilize every two weeks with a mild, water-soluble fertilizer.
