Cause A physiological problem. The exact causes of pit breakage are unknown. Fruit of most early peach cultivars enters the final swell of growth before the pit is completely hardened. As the fruit enlarges rapidly, stress exerted by the expanding flesh causes or enhances much of the pit fracturing. Because most early varieties are cling types, the strong attachment of flesh to pit probably enhances the forces exerted on the immature pit by the expanding flesh. Cultural practices that enhance fruit size such as thinning, nitrogen application, girdling, and irrigation usually increase the level of split pit.
This feeding activity scars the tiny fruit in the blossom. As the fruit grows, the scarred tissues expand to produce the russeted areas on the mature fruit. In the home garden control of thrips is not recommended.
The consumption of scarred fruit is not harmful, and the fruit can be peeled if the scarring is objectionable. Severely scarred fruit may be deformed. If this happens often, a spray of insecticidal soap may be warranted.
Spray in the late evening or at night when there is no bee activity. The splitting of the pit is caused by rapid growth of the fruit and by excessive watering or watering irregularly a good irrigation after a dry cycle. To reduce split pits, do not fertilize peaches or nectarines after bloom, and keep the trees evenly watered or even reduce watering slightly after fruit reaches an inch to an inch and a half size. Skin splitting can have a number of causes and may or may not be related to russeting and pit splitting.
Skin splitting may occur when the fruit gets wet from dew, rain or fog drizzle. Maturing fruit can absorb moisture directly through the skin, and the fruit may expand faster than the skin can stretch to accommodate this expansion.
Split pit is a defect in peaches that occurs when the fruit enlarges too quickly, thereby creating a void or hollow center inside the seed or around the seed. The result of this is a peach that often splits into the open air near the stem, opening a path for fungal or insect pests to invade.
A peach with a split pit is unmarketable. It looks funky and offputting. While the flesh on the outside of the peach may be just fine, everyone expects to see a picturesque pit at the center of the peach surrounded by rich red colored flesh. Excessive rain hello Stephenville, TX , excessive irrigation, and thinning can cause it.
Regardless of the cause, the result is a peach that typically just gets thrown away. Earlier ripening cultivars are more prone to this defect. These pictures are from late May. Depending on the severity of the split pit, your peaches may still be great to eat! Because not all split pit peaches will split all the way to the stem, it can be hard to tell which ones have a split pit. The answer is in whether or not that peach should be ripe yet.
A peach with a split pit will ripen faster than normal.
