The teardrop juniper is a cultivar of Juniperus chinensis called "Blue Point." This variety is highly desirable for its shape, which is rounded on the bottom and comes to a graceful point at the top--much like the shape of a teardrop. The foliage is a distinctive color and quite dense, notes the University of Connecticut's horticulture program.
The juniperus family is extremely broad. The plants range from short ground covers to towering trees. They are somewhat cold-hardy, depending on the species. Blue Point is one of the more cold-hardy cultivars. It can be planted in U.S. Department of Agriculture (USDA) growing zones 4 through 9, reports Maggie's Garden.
Juniperus chinensis trees are soil-hardy plants. They are highly adaptable to all types of soil and can even grow in both alkaline and acidic soils, according to Floridata. Although these trees tolerate poor, dry soils, they grow best if planted in moist, rich, well-draining, fertile soil.
Teardrop junipers should be planted in a location where they have plenty of room to stretch out. These trees grow quickly--they can reach heights of 12 feet and widths of 8 feet--and hate being crowded, according to Michigan State University. Their striking form makes them best used as a landscape specimen plant.
Juniperus chinensis, or Chinese junipers vary in their light needs, depending on the cultivar. Low-lying shrubs and varieties with yellow-green foliage need exposure to full sunlight, reports Floridata. The teardrop juniper, the Blue Point, however, has dark, bluish-green foliage and is upright, so it can be planted either in full sun or partial shade.
Juniperus chinensis are susceptible to blight diseases, in particular, Kabatina and Phomopsis. These are fungal diseases that cause the tips of the twig foliage to turn brown and die, notes Purdue University. Since the fungal spores are spread on water, it is important to plant your juniper in a location that will help keep the plant dry. A site that has morning sun quickly dries any dew left on the tree. In addition, make sure you plant your teardrop juniper in a location where it will not be sprayed by any sprinklers. Finally, make sure there is plenty of room for drying air to circulate around the plant. Do not plant it right against a wall of the house.
