Creating a garden from seeds can be a challenge in Arizona because most of the soil in this desert state is composed of clay. Clay creates a hard barrier that seeds cannot break through. Other challenges when planting a garden include extreme heat and cold and, naturally, very little rain. When planting a garden from seeds, there are things you can do to increase your chances of success.
Determine the types of vegetables desired and verify what season to plant the vegetables. In Arizona, vegetables are broken up into winter and summer varieties, depending on that particular plant's germination requirements. Examples of winter vegetables include broccoli, carrots, peas and spinach. Summer vegetables that flourish in Arizona include eggplants, melon, pumpkin and corn.
Check the soil of the bed being used. If the soil is primarily clay, add an inch of sand to the top of the soil to create a layer for the seeds to break through.
Sow the seeds directly into the soil and lightly cover them with.
Water the seeds daily to keep the soil moist and encourage germination. If planting the seeds during the hotter part of summer, consider placing a piece of cardboard over the area where the seeds are germinating to better hold in moisture and minimize sun scorching.
Water the garden every two days once the seeds are established. Water the sprouts as necessary to ensure the best yield and optimize root space for the plants.
Select varieties of flowers that are indigenous to Arizona to increase the chances of success in the garden. Some examples of indigenous plants include broom snake weed, yellow paper flowers and paper daisies.
Prepare the bed's soil by adding a thin layer of commercial garden soil. Garden soil contains many of the nutrients that are deficient in desert sand and clay and can aid in better holding in moisture.
Sprinkle the seeds in rows and water thoroughly.
Weed and water the flowers as necessary.
Sift some cactus soil into a few 2-inch planting pots. Moisten the soil thoroughly.
Sprinkle the cactus seeds on top of the soil; do not bury the seeds.
Place the pots in an area that receives maximum sunlight. Moisten the soil every three to four days, but avoid allowing any standing water to form.
Mist the sprouts once they appear with a spray bottle to ensure the do not dry out.
Water them every few weeks once the plants are larger. Transplant the cactus outside once the root system has outgrown its container. Continue watering once a month for the cactus' first dry season. If there is any rain, do not water.
