I guess I'm refreshing this thread as I haven't found a lot online that isn't nursery write ups. Hope everyone's atco goyos are doing well .. would love to see some updated photos from the thread
Purchased this pinus parviflora "atco goyo" at the tail-end of winter. Of the ones available (seems everything is grafted these days) it had the healthiest candle growth and the best graft I've seen in a long time. I pulled the tree out of the pot at the nursery to inspect the roots too, I live in the PNW so roots can be mushy come spring thanks to lots of rain over the winter. Roots looked surprisingly healthy and in need of a trim, if I'm being honest.
Next up was to remove all the mulch and the top soil to get to the surface roots, nebari, however you'd like to refer to them. 3" of excess soil and the same in mulch, trimmed off the little capillary roots that were growing from the trunk and combed out the roots at the bottom to find the main root ball. Gave a modest trim and prepared the new training pot.
Wrapped a single coil of 5mm aluminum wire from root ball to top candle. Wrapped branches in 2.5 and 1.5mm wire and started to gently bend the trunk from the base up to the top. I forgot how flexible the JWP are when young and coming out of dormancy with fattened new wood. Once the trunk was in the shape I wanted, I secured the root ball on a base of 6-8mm pumice, topped with my mix of 1:1:1:1 pumice, lava, fir bark, and akadama, I sprinkle a healthy amount of mycorrhizal inoculant for the bottom roots to sit on. I sprinkle a bit more over the top of the root ball and fill the pot in with the soil mix and got rid of the air pockets with a trusty chopstick I save from the take out order the other week.
I filled a dish pan with rain water and a tea consisting of fish bone meal and kelp meal I've been steeping for a week. I dropped the tree in the dish pan until no bubbles surfaced and let it all drain away and the soil settle.
I'll drop some solid food on there in a week or two when the tree has had a little time to get used to it's new home. Pictures are before and after ... I forgot to take a before but for some reason made a video ... so there you go.
