Is the peach still edible?
Stone fruits, such as peaches, nectarines, and apricots, can sometimes develop a condition known as split pits. This issue arises due to a variety of environmental and cultural factors that affect fruit development.
Key causes of split pits include:
- Overwatering or excessive water uptake: When stone fruits absorb too much water, it can cause the flesh to swell unevenly, leading to the hard pit splitting or cracking. Moderate watering is essential for juicy flesh, but too much can result in split pits.[1][5]
- Spring freezes during bloom: Freezing temperatures early in the season can damage the tissues involved in pit formation, leading to abnormal pits that may split as the fruit grows.[3]
- Early thinning and fruit development stresses: Practices like thinning the fruit too early can stress fruit growth, contributing to split pits, especially in early-ripening varieties.[5]
- Weaker tissue resistance: Some fruits, such as apricots, peaches, and nectarines, have slight differences in tissue strength, with apricots being more vulnerable to internal damage, which may increase susceptibility to split pits under stress.[2]
It's important to note that split pits can also be caused by human-made factors, such as thinning the tree during the growth phase.[4] Researchers advise against thinning the tree until the pits are ripe and hard to reduce the risk of split pits.[6]
Regarding safety concerns, the inner pit of stone fruits should not be eaten due to the presence of amygdala, which can be converted into toxic hydrogen cyanide in the body. However, the fruit flesh contains only very small amounts of amygdala, making it safe for consumption for children and adults.[7]
If you encounter a split pit in a stone fruit that is moldy or the fruit flesh is unusually hard, it's better to discard the fruit as a precaution.[8] Split pits in stone fruits can be eaten safely in most other cases.
By managing water levels properly, avoiding damage from cold snaps, and being mindful of thinning practices, growers can significantly reduce the incidence of split pits in stone fruits.

- Excessive watering or water uptake, as well as other human-made factors like thinning the tree during growth, can lead to split pits in stone fruits like peaches, nectarines, and apricots, affecting health-and-wellness and food-and-drink safety.
- Resistance of the fruit tissue is crucial in preventing split pits; for instance, apricots, a popular stone fruit, have weaker tissue resistance and are more susceptible to internal damage.
- Implementing proper water management, avoiding cold temperatures during the bloom season, and taking care during thinning practices can help reduce the occurrence of split pits, promoting a healthier lifestyle and nutrition through the consumption of stone fruits.
