Cascade bonsai growth patterns relative to height of tree

I’m taught that trees grow from the top, so how does that work in a cascade wherein the tip is lower than the base(in some cases)? Does the vertical placement of branches .dictate which branches grow best?
I have this juniper potensai training to be a full cascade and it’s in the ground; how does this position effect the cascade growth? Are there tricks that I should know re: growing cascades?

Exactly the vertical placement does play a roll in the amount of energy and growth transferred to the foliage.
The challenge with cascades is to achieve a balance between the apex and the lower portion of the tree. This is done by continuously thinning and pinching the apical area to distribute more energy downward to the cascade area.
This balancing is continuous to keep the overall design healthy! At times the artist will position the tree temporarily to give the cascade more elevation and thus strengthen the lower foliage.
There is a section devoted to the challenges of Juniper cascades in the Masters Series Juniper book. This is a good reference if working with Juniper and it is available through Stone Lantern publishing.

I’ve had a thought re: cascade trees. How about laying the tree down on the side opposite the cascade and let the sun do its thing? Anyone ever try that?

An afterthought. I just picked up a true weeping dwarf jap maple grown from seed. It’s got a great main branch going downtown. The nebari isn’t bad. It has three surface roots about 120 degrees apart. More later.

Good thought. That is a common technique to strengthen the cascade portion and retain balanced growth.

Somehow I knew that the thought probably wasn’t original. “Nothing new under the sun than that
which is common to man”. Do you live on St. Victoria Island? If not, what is the name of your island/town?

I live on Vancouver Island near the town of Parksville, British Columbia, Canada. Small acreage backing on to protected parks area near the Englishman River. Vancouver Island is just off the coast of British Columbia and the city of Vancouver BC. Victoria is the capital of British Columbia and is also located on Vancouver Island about two hours south of my location.
