There are 200 different species of jasmine (or Jasminum), including trees, bushes and vines. It's best grown outdoors in warmer climates of zones 6 through 11, depending on the variety. This fairly fast growing small tree---12 to 24 inches a year---reaches up to 15 feet at maturity. Most of the varieties bloom small, delicate, star-shaped white flowers in the spring or summer, the first six months after planting.
Plant your jasmine tree in a sunny location of your yard, June through November. The tree will, however, withstand some shade. It is not too particular about the type of soil, doing well in ranges from sandy to slightly clay soil. Mixing compost into the planting soil will offer needed nutrients the first year. If you plant more than one tree, space them a minimum of 8 feet apart.
Insert a stake into the ground next to your young, newly planted jasmine tree. Use plant ties to secure the tree to the stake. This will assure that the tree grows straight. When the tree has established itself the following year, you can remove the stake.
Fertilize your jasmine tree the following spring after planting. Use a high phosphorus fertilizer, such as 10-15-10 as this will encourage lots of blooms on your tree.
Add chelated iron to your fertilizer if the leaves on the plant turn light in color. Jasmine trees do require an ample amount of iron.
Apply plenty of water, every seven to 10 days, keeping the soil moist during the growing season (late spring and summer). However, do not water to the point of sopping. It would be better to water smaller amounts more often, rather than once very heavily. Reduce your plant's water intake during the rest of the year, unless you have a particularly hot, dry period.
Protect your jasmine tree if the temperatures dip below 50 degrees Fahrenheit. Place a canvas or tarp over the top.
Clip your jasmine tree in early spring, before it shows signs of new growth. Start by removing any broken or damaged limbs. Prune them at the trunk of the tree. Then, shape the rest of the tree to your desired height and shape.
