Fruit Cracking: Understanding the Causes and Solutions for a Healthy Harvest

Fruit cracking is a common problem faced by many gardeners and farmers, resulting in significant losses and disappointment. It's a phenomenon where fruits, especially those with a high water content, split open, making them unsuitable for consumption. In this article, we'll delve into the causes of fruit cracking, its effects, and most importantly, provide you with practical solutions to prevent and manage this issue.

What is Fruit Cracking?

Fruit cracking, also known as fruit splitting or fruit bursting, occurs when the skin of a fruit becomes unable to withstand the internal pressure caused by rapid growth or water uptake. This leads to the formation of cracks or splits on the surface of the fruit, allowing bacteria and fungi to enter and cause decay. Fruit cracking can affect a wide range of fruits, including tomatoes, peppers, cucumbers, squash, and melons.

Causes of Fruit Cracking

Several factors contribute to fruit cracking, including:

1. Rapid Growth: Fruits that grow too quickly can develop cracks as the skin struggles to keep up with the expanding flesh.

2. Water Uptake: Fruits that absorb too much water can become over-hydrated, leading to skin splitting.
