|Liberty apple on MARK rootstock. MARK is now considered obsolete.
We had thunder storms blow in while we were fishing last night. No fish were caught. We picked up 2" of rain in the last 24 hours.
The light was murky, consequently the colors in the pictures don't "pop".
|Wild Plum. In this case, Prunus nigra or Canadian Plum. It is possible that a few pieces of scionwood from this bush followed me home a few years ago.
Rewind: Fifteen years ago I was hunting deer in that woods and the edge was a nearly impenetrable thicket of blackberries. Deer and bunnies like to bed in that dense thicket. Birds fed on the berries and bugs and nested in the dense tangle. With all the light hitting the ground, that thicket should have extended fifty feet deep.
Putting those two phenomena together, is seems obvious that careless post-emergence spraying of glyphosate had a huge impact on the forest floor along the edges of farm fields. That is forcing me to rethink what and how I am going to plant mast crops to take advantage of the ash and elm die-off.
I presume some species of mast producing trees and bushes are more tolerant of glyphosate than others but it is not well documented. At this time, the only strategy I can think of is avoidance. That is, to use species that leaf out later in the season, to use "tree tubes" and to plant taller trees with the lower branches pruned off.
I assume I could build a linear brush-pile to give the spray something to plate-out on but that is a lot of work.
This is going to take some thinking.
