Dig a hole twice as wide as the jasmine plant root ball. Measure the depth by placing the potted plant into the hole and verifying that the top of the root ball is level with the top of the soil.
Line the bottom of the hole with rich organic matter, such as compost or peat moss. Be generous, because the jasmine plant thrives in rich soil.
Place the jasmine plant in the center of the hole, and cover the root ball with dirt. Add handfuls of sand mixed with dirt if your flower bed has a lot of clay in the soil. Jasmine plants do best in well-draining soil. Press the soil firmly around the plant with your hands to eliminate any air pockets.
Water the jasmine plant every 5 to 7 days, so the soil is moist but not soaking. Water more frequently in hot months, about every 3 to 5 days.
Fertilize the jasmine plant with a half-strength, neutral liquid fertilizer with low nitrogen. Apply fertilizer once per month during the growing season, from March to October.
Trim the jasmine plant only after the flowers have dropped. This promotes more flower production in the following year and lets you shape and train the vines to go where you want.
