Plant Description:
- -
Juniperus erecta, also known as the upright juniper, is a species of juniper native to northern and central Europe, as well as Asia. It is an evergreen coniferous tree or shrub that grows to a height of 15-25 meters, with a conical to oval crown. The leaves are needle-like and are about 2-4 cm long. The species is valued for its attractive, dense, and upright habit, as well as its tolerance of cold temperatures and dry soils.
The variegata variety of Juniperus erecta has leaves that are variegated, meaning they have white or light-colored markings or streaks on them. This variegation is caused by a genetic mutation that results in the production of chlorophyll in only some of the cells of the leaf. Variegated plants are prized for their distinctive appearance, but they can be more difficult to grow than solid green plants, as the variegated parts of the plant may not produce as much chlorophyll as the green parts and may be less able to photosynthesize effectively.

Growing tips:
-
Here are some general care tips for Juniperus erecta variegata:
-
Light: This plant prefers full sun to partial shade. It can tolerate low light conditions, but it may not grow as well and may lose some of its variegation.
-
Water: Water the plant when the top inch of soil feels dry to the touch. Avoid overwatering, as Juniperus erecta is prone to root rot if the soil is consistently moist.
-
Temperature: This plant is hardy in USDA hardiness zones 2-7, which means it can tolerate cold temperatures down to -50°F (-46°C). It is not tolerant of high heat and humidity, so it is best to avoid placing it in a hot, stuffy room.
-
Soil: Juniperus erecta prefers well-draining soil with a slightly acidic pH (5.5-6.5). A mixture of equal parts potting soil, perlite, and peat moss can be used.
-
Fertilizer: Fertilize the plant once a month in the spring and summer with a balanced, water-soluble fertilizer. Do not fertilize in the fall and winter, as the plant is dormant during these months.
-
Pruning: Prune the plant as needed to maintain its desired shape and size. Juniperus erecta can be pruned into a formal shape, such as a pyramid or column, or allowed to grow more naturally. Use clean, sharp pruning tools to avoid damaging the plant.
-
Pests and diseases: Juniperus erecta is generally resistant to pests and diseases, but it can be susceptible to juniper blight, a fungal disease that causes brown or black dead patches on the foliage. If you notice any signs of disease, remove and destroy any affected parts of the plant and use a fungicide according to the label instructions
