Tips on encouraging new growth on a juniper

Post  Steven on Thu Jun 07, 2012 2:09 am

I purchased this small tree (30+years old) last year...when I purchased it, I was told it had spent most of the last 10 years in the same pot without repotting, it was also located in almost complete shade with very little sunlight and has never really been styled. I saw some potential for it to make a nice shohin some day so I took a chance and rescued it. I removed it from the tiny pot it was in to discover that a lot of the root mass was starting to rot away from poor drainage, after cleaning up the roots and potting it into a much larger tub to motivate some re-growth and healing it seems to have made a steady recovery and even produced berries this year. While it seems to have made a steady recovery I still have not seen much new growth and despite some hunting haven't found a lot of info other than continued feeding regime and proper lighting, do junipers this age back bud easily?


The tree as I purchased it





I will have to get a picture of its progress tomorrow

Here it is in its present state, it had a good bit of room to grow in this larger pot, but if it will speed up the foliage growth I could always put in a much larger nursery pot, any ideas? Sorry the photos aren't great. Up to this point all I have done is remove the unnecessary dead branches, feed/water, and let it recover as I wanted a bit more vigor before I started shaping, I also haven't done any cleaning or work on the deadwood piece in the front yet either

How much of the root ball did you have to remove?

Not that much just the tips of the bottom few inches of the root bound mess that was in the original 7" cascade pot, which was a season ago, and I definitely have an abundance of new feeder roots as I discovered while doing some weeding of my pots.

Ok,

From what you've said you're feeding and watering well and providing it with plenty of sunlight. That's pretty much what you need to do for it. From the second round of pics they show me that the tree is weak and it's going to need the time and care to get strong; I would just focus on that.

As for back budding and foliage growth, again, as the tree gets stronger it will take care of itself. I've had junipers weaker than yours and by concentrating on the its basic needs they've thrived; it just takes time.

It's an interesting piece of material, what type of juniper is it?

Honestly I am not too sure, I have done some searching to try and ID but I end up with a handful of options that all look similar, any ID help is also much appreciated. The previous owner collected it years ago and had kind of neglected it for a long while, never really doing anything with it. I am just glad the tree is starting to recover little by little, and the time it takes will give me more time to figure out what I want to do with it lol. I also got a nice 15 year old mimosa, and a tiny 20 year old boxwood which have both made quick recoveries since receiving a much needed repot with better draining soil and good water and feeding.

What i have done on a similar tree is also is remove perhaps 5-10% of the foliage furthest away from the trunk. Maybe I was lucky but got a strong shoot right back on the trunk and some others on old parts of branches. I wont remove any more until another year. Sounds like you have the general health of the tree under control Smile good luck.

It might be a Parsons juniper, J. parsonii. If not, definitely a "chinensis" cultivar. Have you checked the foliage for spider mites?

We appear to be mite free, after purchasing a spruce once that was covered in them I try to stay proactive in monitoring my mite meal trees, thanks for the id help

I too have had luck with removing by finger pinching the foliage on the bottoms of all branches, which also helps tidy up the appearance while helping to force growth back towards the trunk. Somehow the older foliage seems to have lost it's vigor and color. The new growth may take a few weeks to show, but by then you should notice better color as well as new juvenile foliage (different shape--more needle-like). If you dont feel good about doing all the branches, try doing one or two and see if the foliage on the major branch changes appearance. If so, you can do the rest. It worked for me on an older raft I picked up at an auction that seemed to be stagnant, for lack of a better word.
