This cultivar was first introduced in 1949 at Schuel Nursery in South Bend , Indiana , and was originally ring ‘ Pilaris 1 ’ before it was rename . sassy pick , in my opinion .
It ’s often mislabeled asJ. virginiana , aka easterly red cedar , and while you may certainly see the resemblance , this cultivar is from thescopulorumspecies .
These two mintage usually hybridize when they develop in the same area , so it ’s no surprisal that multitude confuse the two .
The Rocky Mountain species naturally has a columniform form , and ‘ Skyrocket ’ has been breed to exaggerate this increase habit . It has a fastigiate shape , meaning that it ’s extremely upright and candle at the top .
The leave are bluish - green and scale - alike , overlapping along reddish - brown or grey - brown barque . When youthful , the leaves are more pointed and gray-headed before rounding out a small and adopting their matured chromaticity .

To take a cutting , take away a young , pliable stem about the duration and diameter of a pencil from the parent works , defoliate the bottom one-half , and place it into a growing medium . Keeping the grime moist as you wait for roots to acquire . It ’s not a prompt process , but it ’s not challenging .
For a step - by - whole tone walkthrough of the unconscious process , please gossip our guide to develop junipers .
To settle a transplantation into the primer , you ’ll require to dig a hole about the same size of it as the container the industrial plant is currently grow in . Do this in the spring or former drop .
mildly withdraw the plant and loosen up the roots a little . You want to encourage the roots to grow down and out , not sophisticate back into the rootball , which can bechance if you do n’t loosen up roots that have been growing in a passel for a few years .
Once the plant is in the ground , backfill the muddle with the remote stain and lightly water supply .
Because ‘ Skyrocket ’ plant are so narrow , you may plant them close together without exit too much blank space .
Unless you live in an extremely humid country , you do n’t need to worry too much about air circulation . Plant ‘ Skyrocket ’ plant two feet aside if you require to create a shelterbelt or fence .
Give them more breathing way if you do n’t want a strong rampart of green , or prefer to create focal points .
How to Grow Skyrocket Juniper
Since ‘ Skyrocket ’ has a shallow root system design to cling onto sandy , arid territory , do n’t even conceive about assign this plant in poorly - drain , heavy clay grease .
The bush also needs a cheery spot with full sun photograph . We ’re speak at least eight hr of direct sun per twenty-four hour period .
I know it ’s tempting to found something you really enjoy even if it is n’t exactly right for your area and promise for the best . Plus , you often get word about how well-to-do junipers are to grow , correct ?
That only applies if you develop them in the right environs . Put them in a umbrageous spot with poor drainage , and you ’ll find they ’re not so easy after all .
I always think ‘ Skyrocket ’ raetam were the least demanding specimen growing in my garden .
In my premature place , I planted a course of ‘ Skyrocket ’ junipers to create a live on fencing along a busy road , and I jolly much ignored them after the first yr . Though you well think I enjoy the privacy and sound - dampening force they provided .
I also planted one as a centrepiece for a garden and to provide a wintertime focal point , and it stood marvelous there without any work on my part year after year . I would give it a mental hug as I toiled around my demandingrosesand forever strugglinghydrangeas .
Then I travel somewhere with backbreaking clay , and I figured if I just ameliorate the heck out of the soil and was measured about watering , they ’d be fine . I was wrong .
If you have laboured clay , unless you may commit to dig up down at least six foot deep and ten feet wide to amend the soil , I ’d suggest you consider planting a dissimilar bush . Or you may grow it in a raised bottom .
I have neighbors who successfully grow Retama raetam , but they have sloped yard held in spot by rock retaining wall so the wet run out out more readily .
Other than not tolerate heavy cadaver , ‘ Skyrocket ’ is pretty adaptable to a range of a function of environments and soil type . They ’ll adapt to a wide pH scope , from 5.0 to 8.0 . arenaceous loam is idealistic , but anything from arenaceous to loamy clay will do .
But it does n’t do well in area with high heat and humidity , such as you find in the extreme southern states , Hawai’i , and the very bottom of southern California .
For the first yr , you need to keep the etymon a bit more moist than you will need to in the occur yr . tolerate the top column inch to dry out out between waterings . After the juniper is more established , rent the top three inches dry out .
If you ’re sputter to keep the stain moist , an inchlayer of organic mulchlike well - rottedcompostor tear up conifer wood will work nicely .
‘ Skyrocket ’ is n’t the better option if you want a container juniper . It is too improbable , ask a monumental , heavy stack to contain it . But , if you desire to make a rattling statement , go for it .
Find a heavy concrete or clay sens that ’s at least 28 inches in diameter and just as abstruse . Bonus points if you discover one that ’s a flake wider than that .
verify the container has excellent drainage . Otherwise , just contrive on set fire to the money you ’re spending on the tree and container , and relieve yourself a stair .
