Gardenia jasminoides "Veitchii" grows to heights of four-feet tall and three-feet wide at maturity. This evergreen shrub has green leaves that complement double white blooms. Preferring filtered intense sun and well-drained soil, gardenia veitchii plants require very little maintenance once planted. You can successfully plant and enjoy the fragrant flowers of the gardenia veitchii shrub in your own outdoor landscape if you live within USDA hardiness zones 8 through 10.
Use a soil pH testing kit to determine the pH of the soil before planting the gardenia veitchii. Gardenia veitchii prefers soil with a pH between 5.5 and 6.5.
Add lime to the soil if the pH levels measure below 5.5, or add peat moss for soil that measures above 6.5. Add the required amendment according to manufacturer's instructions, followed by a four-inch layer of compost for extra nourishment.
Prepare a hole for the gardenia veitchii using a sturdy shovel. Dig the hole twice the size of the root ball and equal to its height. Remove the gardenia veitchii bush from its nursery container and place it in the center of the hole.
Backfill the hole with the soil that you originally removed. Gently pat down the soil around the stem to remove air pockets. Water the gardenia veitchii deeply with a soaker hose. Provide the plant with at least one inch of water per week for the first growing season.
Apply a three-inch layer of mulch around the gardenia veitchii to reduce weed growth and help with drainage. Use straw, grass cuttings or bark chips for mulch. Keep the mulch at least three to four inches away from the wood of the stem to reduce pest infestations.
