Field Growing 3: Spreading Roots & More

Digging a field grown Japanese Black Pine. From Bonsai Today, issue 75.

In Field Growing 2 I said I just dug a hole and planted. Actually, that isn’t the whole story; when you field grow bonsai stock, you need to cut off the downward growing roots and spread the lateral roots. This encourages lateral top growth (above ground growth) and nebari development (check the top photo in Field Growing 2).

Some people put a board, or tile, or some other flat object a few inches under the roots to inhibit downward root growth and encourage lateral growth. Others, like me, just dig their plants up every couple years and prune and spread the roots each time.

Chinese Bonsai Tools

Five piece carving set. Made in China.

For years we’ve resisted importing Chinese tools. Japanese tools were absolutely superior and more-or-less affordable, and Chinese tools, though very affordable, were mostly inferior.

Now, all that is changing. Robert Steven (accomplished bonsai artist, author of Vision of My Soul and major player in the Asian and world bonsai communities), has founded a line of Chinese tools that are quite good. And, compared to the ever increasing prices of Japanese tools, a very good investment; at least for those of us with tight budgets.

Energy Balancing

cascade-pine-book-p1753-corrected
This powerful old cascading Japanese Black Pine (Pinus thunbergii) is a masterful example of how energy can be directed downward in a tree that naturally wants to grow upward. The photo is from Bonsai Today Master Series; Pines.

Whenever you prune, trim or pinch, you are redirecting energy.

If you remove a branch the energy (primarily water, gases and nutrients) that would have flown into that branch goes somewhere else. Some of it goes to forming a callous where the branch was, the rest goes elsewhere.

Basically energy flows two ways in plants; up from the roots, and back down from the leaves. For bonsai, it’s the up from the roots that we are primarily interested in.

Field Growing 2: Native soil

trident-nebari-bt64-p231 This impressive Trident maple’s (Acer buergeranum) massive nebari is a dead giveaway that it was field grown. The original article is in Bonsai Today issue 64.

I once read a report from Cornell University (I can’t find it; anybody?) about the advantages of planting trees directly into the native soil, rather than the common practice of digging in soil amendments, a practice that may be good for the garden center’s bottom line, but not so good for your plants.

If you think about it, it makes sense; if you create a pocket of richer soil, then the roots tend to stay in that pocket. In the not-so-long-run, this causes slower growth and increased susceptibility to drought and winter kill (this may be more relevant to landscape planting than to field growing bonsai, but in my case it works for both).
