All week, I've been watching pecan trees as the buds start to swell and the first signs of new green growth appear. What I've noticed is that not all pecan trees break bud at the same time. I'm not talking about the timing of pecan budbreak in Texas vs. trees growing in Kansas. The differences I've noticed this week have been among trees all growing in my local area.
Earlier this week, I noticed that the Kanza trees growing on my farm had
buds that had split open to reveal just the first glimpse of green
tissue. With my interest peaked, I immediately went down to the Pecan
Field to check on the progress of Kanza trees at that location. What I
found were Kanza trees with buds showing just the initial signs of bud
development (photo at right). Here was the perfect example of how soil type can impact on early spring tree growth. The tree on my farm is growing in a Cherokee silt loam soil. The tree at the Pecan Field is growing in a Osage silty clay. The lighter the soil texture, the faster a soil warms up in the spring. Spring root growth is stimulated by warm soil temperatures and once the roots start to grow, bud growth follows shortly there after.
