Our pecan trees are still waiting for some warmer temperatures (especially warm night-time temperatures) before bursting out with a new crop of leaves. This year, pecan bud break is proceeding slower than normal. The buds have swollen but leaves have not yet emerged (photo at left). This slow bud development has been a blessing as we have experienced several hard freezes in early April and not suffered any cold injury.
The pecan grafting season will start late this year. I like to see the first signs of leaf burst on stock trees before making any grafts. At this point, I probably won't carve a single scion until early May.
