Last year I posted a piece on using fire mimicry to treat early leaf senescence in California buckeyes. A few days ago I checked up on these buckeyes and re-photographed them. As you can see in the photos posted here the buckeyes are continuing to show improvement after tending with fire mimicry practices.
When I first saw these trees in 2005 they appeared to be severely stressed due to soil acidification. The lawn areas around their base had a dense cover of mosses growing among the grasses. The mosses were removed by thatching the lawn areas and the soils were treated with several hundred pounds of soil minerals (Azomite and calcitic limestone).
These and other results (see here and here) are showing that the fire mimicry practices which are working so well in restoring the health of the oaks (see here, here, here, here, here, etc.) are also useful in restoring the health of other kinds of trees. This certainly makes sense if the problem is ecological (e.g. fire suppression, soil acidification, overcrowding, etc.) rather than pathological (e.g. disease, insect pests).
I encourage anyone who is interested in getting more information on the methods and services of tree care and forest restoration shown here to please contact me.
