Juniper Rigida Shohin (Winter Update)

As we continue to endure the poor light and atrocious weather conditions of a bleak mid winter here in Scotland, I thought I would take the time to share my first seasons experience of looking after a Juniper Rigida shohin that I acquired at the beginning of last year.

At the time of purchase, I had no experience at all of working with this species, so the initial plan was to feed it, let it grow and see what happened.

This is a reminder of how it looked when I brought it home


After a few weeks of feeding, lots of new shoots emerged but these were lime green in colour and not the dark green I expected. Having no experience with this species, I assumed that as the foliage hardened off in the late summer that it would take on the deep green colour of the mature foliage but that did not happen to any great degree.


Compare the picture above to the next 2 pictures, which shows another smaller rigida purchased at the same time, from the same stock by my friend Gerry. By late summer, this had put on a lot of rich green new growth and was ready for a first styling.



At the moment, my best guess is that my tree may be suffering from a mineral deficiency or a problem in the soil.As the summer was ending I was concerned about the poor drainage. Meanwhile, if anyone out there has experience of this, I would be most grateful to hear from you.

My plan at the moment is to get it out of the pot it is in at the earliest opportunity in order to get a good look at the soil and the condition of the roots. I will also try a magnesium supplement

Here are 2 possibilities for the re-pot.

  1. It certainly could be a mineral deficiency- or a nitrogen imbalance- or if you feeding regime is or should be covering all that check the pH of the solution. Plants generally do well with a pH slightly below 7. An alkaline pH can indicate “nutrient lock”. Any sever pH extremes could cause root damage. All lead to the bright color you are seeing. I would confirm appropriate nutrient were given and pH is appropriate for the species (or compare to your friend’s) and see what information that gives you…

  2. Repotting in the spring is definitely a good idea. Use a nice free-draining soil. You might find that some of the deadwood under the soil is rotten and that you have a problem with some of the roots too. Fingers crossed!
