Having been hit hard by the freeze in mid-January, the cherimoya trees are now budding again. This one shown here is the ‘Helmuts,’ probably the second hardest hit of our orchard’s block of cherimoyas.
The tops of the branches are killed back (i.e. the extremities suffered most from the cold), but the remainder of most branches is alive and now sprouting the growth of spring. Note the brown leaves clinging to some parts of the branches. Dead leaves cling to dead wood. Living tissue pushes its dead foliage off, and so now I realize that the massive leaf fall shortly after the freeze was a good sign. At the time, it sure did not seem that way!
Normally in this region, cherimoyas defoliate for a very brief period in April, thus making the cherimoya, at least in our climate, a rare case of a deciduous subtropical, albeit one that drops leaves only after the real deciduous trees have leafed out following their months of winter dormancy. These trees have now been mostly without leaves for over two months, and I had feared that they would be far off their normal cycle if they re-leafed too soon after the freeze. But now they are only a bit early, and I suspect they will get back to normal fairly soon, despite the shock. In fact, they might even bloom especially well this year, there being nothing like instilling the fear of death in a fruit tree to get it “thinking” about reproducing! Whether they can hold and ripen fruit their first year after such a big setback to their internal energy levels is another matter.
