Shimpaku juniper cuttings repotted

A few weeks ago on ebay I purchased 10 rooted shimpaku juniper cuttings.


They sat out in the garage until the temperatures warmed up. I was worried being from northern Florida that they wouldn’t be so cold hardy. Upon a soil debate on Bonsai Nut, I decided to try two different potting mixes for them. Last night and this afternoon I repotted them all.

One set were put into two parts pumice, one part turface, one part pine bark. 


The other set were put into two parts pumice, one part turface, and one part akadama.


All of the plants had mycohrizae spores dusted on the roots, then the top soil was dusted, then they were watered. 




The five with the bark are in back. The second set with akadama are in the new pots in front.


I would have used more akadama, but felt like it would be a better comparison with equal ratios. I plan on treating them the same as far as fertilizing and watering goes. I would like to see if there is a difference in vigor and growth between the two mediums. The plan is to grow them out as whips and then wire them into a twisted shape then in a couple years on up-pot them, probably into pond baskets.

  1. I like the idea about pottuing in the two substartes. I think you will find that unless you fertilze with organic fertilizer or add a humate, you will see no difference. A better test would be keep the akadama soil planted ones with organic and humates and the other with turface chemical fertlizer.

    An even better test would be to change the size of the substrate to all particles the size of turface and the other the size of about 5/16″ for a better interchange of air.
    I will be willing to bet a years salary that the greatist change will come from the increased air exchange.

  2. I’m curiouse to know what the results will be, let us know! I have been expirimenting with hydrophonics and bonsai myself. I planted half of Serissa and Ficus cuttings in soil and the other half in an Ebb & Flow. The hydro cutting grew out of control, almost scary.
