Pruning Catalpa tree meristems has forced lateral growth. The tree has reacted to our limitation of it’s vertical growth with lateral propagation of branches with auxillary stipule meristem configurations at multiple leaf axils.

I am looking forward to my Catalpa’s defoliation subsequent to the autumnal equinox. I will then see how the density of branches has increased relative to the propagation points at the axils. And, pruning thereafter will reduce the branch array to the desired sculptural form. I believe that sequential subsequent annual prunings and each year’s regeneration of foliage from the temporal arboreal prunings at vernal equinox times will eventually produce an exemplary caplyta.

Similarly, early this year, I felled three Acer rubrum of 3″-4″ dia., at DBH, and have observed them struggling to regenerate sclerenchema, parenchyma and spongy mesophil capacities facilitating a capillary action through the damaged cambium via evapotranspiration such that I have determined seasonality to be important therein. Accordingly, as we near next year’s vernal equinox I believe that similar severance of vascular cambium in several more rubrum, via felling at DBH upon the eqinox, will continue my experimental effort to make of the rubrum what I term “Versailles Maples”.

The Catalpa will eventually flower, and, in that there are dozens of red maples north of my home; I am hopeful that the next few vernal seasons will produce a process for the following decades of arbory here.
