Juniperus chinensis 'Robusta Green'
Overall Description
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
to
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: Either
water soluble ( Miracle Gro, or equivalent ), or granular ( Holly Tone
is excellent ). Other granular types with 6-12-12, or 10-10-10 ratio is
acceptable. Best to fertilize in early spring, and again in mid fall -
avoid feeding during hot summer months, and directly after
transplanting.
