Juniperus chinensis 'Robusta Green'
Slow to moderate
growing, dense columnar juniper with scale-like green foliage with a
hint of silver / gray to it. Takes on a somewhat "twisted", upright, columnar
shape with age. Peeling red/brown bark, and grayish green berry-like
cones are produced in abundance. Will thrive in most any soil conditions so long as it is well
drained. Excellent for use as an accent plant, or when planted in a row
as a border/screen.
Works very, very nice when planted along building fronts, and gated entrances, etc.
Plant Facts & Specifications
--Mature Height: 12 - 15 ft
--Mature Width: 3 - 4 ft
--Growth Rate: Moderate ( 4" - 8" avg per yr )
--Hardiness Zones: 4 - 9 ( if unsure of your zone, please use zone finder below )
--Sun Exposure: Full
sun preferred, but will tolerate some partial shade as well. Growth rate & foliage density will
suffer slightly in shadier spots.
--Soil Preference: Average
slightly acidic & sandy - well drained. Mulching recommended.
Adequate soil drainage is a MUST with this variety - will do poorly in
heavy clay soils, or soils with poor drainage.
--Foliage Color & Texture: Both awl shaped, and needle type foliage are displayed on this variety in a very irregular, sometimes "twisted", or "contorted" manner. Good dark green color - even through the winter. Very rigid branches - prickly to the touch.
--Flower, Cone, Or Berry Facts: Robusta Green produces a very large amount of small round grayish white cones. Cones are approximately the size of a large pea, and persist on through the winter.
--Diseases / Insects:
Rather trouble free juniper variety - both Phomopsis & Kabatina blights have been observed on specimens, especially if kept in conditions with too much moisture or inadequate soil drainage.
--Fertilization / Feeding: For maximum health & hardiness, we highly recommend a good grade granular ( preferably organic ) fertilizer / plant food for use with all of our plant species. We personally use, and recommend the Espoma line of organic plant foods, as they are super effective yet gentle enough to use on even the most delicate of evergreen species where fertilizer burn would normally be a major concern. However, a water soluble type plant food (Miracle Gro, or equivalent ) are also acceptable options. Other granular fertilizers with a 6 - 12 - 12, or 10 - 10 - 10 ratio can also be used - but we suggest using them at 1/2 - 3/4 strength to avoid any chemical burn issues to the root system of the plants. Best to fertilize in early spring, and again in mid fall - avoid feeding standard chemical fertilizers during hot summer months, and directly after transplanting. The Espoma Organic Plant Foods may be used at anytime.
