Hello from your newest member.............
I recently completed a new home project on the coast of Northern California, that included the Sonoma County mandated requirement for 40+ new trees on what was formerly pasture land overlooking the ocean.
The trees (5 gallons when planted) have been in the ground for almost 2 years and have not progressed very well. They are (were supposed to be) Macrocarpa Cupressus or Monterrey Cypress (MC). Photos below.
As part of my investigation of this problem (more in a moment) I tried to identify them as truly MC and not some other variety. I have several other of MC trees that came from the wild that are on the same drip system, some older and larger and some smaller and younger and those trees are all doing fine. The trees in question all have a smaller than pinhead white spot (that is easily scraped off with an exacto knife) on each of the sections of new growth and that remain there until the growth dies - as all new growth on these trees do.
At present, there is only new growth on the top of the trees (most are about 3+' tall). A neighbor recently planted 300+- 1 gallon trees on his acreage and all are taller and healthy and without the white spots.
So, a couple of questions:
Are the white spots indicative of a variety of Cypress or is it indicative of the problem that they are suffering from.
Personally I think they are suffering from some sort of root problem, like fungi, rot or are root bound and were not properly installed???
The trees have all (both the problem trees and the others referred to above) have been drip irrigated with the same twice a week with about 1.5 gallons per application. I changed the emitters at the end of last summer to provide a more circular pattern and they seemed to do much better, until the fall rains began and I turned off the drip system - they are now the worst I have seen them. I don't think they have had too much water, but I could be wrong.
One other observation: the branches at the juncture of the trunk have a slight thickening in some no so isolated cases.
Finally, I almost forgot. The neighbor's trees are not bitten/munched on by our herds of local deer, but these trees all seem to be enjoyed by the deer as do my other trees from other sources
I'm sure I have not provided enough info here, but this may be good enough for a start.
The photos attached below are of the same tree.
Appreciate any and all help.........
Many thanks,
Nick
