My earliest peach, Earlitreat, in previous years has given me delicious fruit at this time of year. This year, although the tree is loaded with fruit, there are problems.
- Possibly unrelated and not necessarily a problem for me is that many of the peaches are dimpled, but show no other external problems.
- Although the fruit is hard to pick from the tree, many are falling off rotten, possibly due to what looks like small holes (insect damage?) that progresses to rot of the bottom of the peach.
- Most I have picked so far, and those that fell on the ground, have split pits.
- Although rotten fruit is dropping, others are holding tight to the tree requiring much effort to pick them. To me, that indicates they are not yet ripe. Also they are not sweet.
Each of these items may be unrelated.
The tree is 6 years old, kept about waist height with summer pruning, never fertilized but always put on good growth and blossoms. Despite years of drought and no supplemetal watering, it and my other trees never looked stressed. Dormant trees sprayed 3 times with Daconil, no pesticides. It is currently loaded with fruit despite having been thinned.
This winter, California emerged from years of drought with rather heavy (for us) rainfall through March with periodic light rain since then.
Next in line for harvest is FlordaKing in about two weeks. No evidence of dimpling there.
