I believe there are 4 native American juniper trees: 1. Rocky Mt. Juniper, 2. Serra Juniper 3. Utah Juniper and 4. California Juniper. Ryan stated, that the 4 species are all elongating species.
Would you treat the 4 species the same?
Can you prune all these juniper the same?
Water them all the same ?
Would you do anything differently to one species verses the others?
Why I ask is I was given a CA juniper – And Ryan has live stream mostly Rocky Mt. Juniper. I am trying to inter- link the practices of above junipers – to all of them.
Also…Juniperus virginiana and Juniperus communis which actually encircles the globe in the northern hemisphere. The internet says Juniperus californica is closely related to Juniperus osteosperma ( Utah juniper) I found only one stream about CA juniper https://live.bonsaimirai.com/library/video/california-juniper-legacy …. The difference among junipers is either running or clumping foliage development. In north America the pruning should happen after the foliage harden off, usually late summer or early fall. Do not pinch, do not prune roots hard until it is incredibly healthy. CA and Utah both survive in desert climates, so can take dry periods, but having no tap root they need to be watered more than a plant in the ground does.
Stream says they love water, love nutrition, recommends 2:1:1 soil mix. 2 parts akadama, 1 part pumice, 1 part lava .Leaves finer 1/16th sifted soil in to help retain, moisture, nutrients and get finer roots and therefore finer ramification. Need lots of sun and likes heat. Pruning process :can prune anywhere as long as there is strong secondary growth behind the prune. Do not cut back to weak side branches or you will harm the tree. All junipers need to have significant foliar mass to move water through the tree. Watch the stream and clean the tree well to make the best photosynthesis foliage that you can. The more foliage the stronger the tree. Common error is to over prune and weaken the tree. CA juniper is not resistant to cold, so need to be protected from freezes. TREES OUTSIDE DID NOT SURVIVE BELOW 28 DEGREES F.
Good luck, watch the stream, you have much more knowledge by being a part of this educational network.
