Catfacing on tomatoes is a disorder that affects the appearance and shape of the fruit. When a tomato develops catfacing, its surface becomes puckered and distorted, resembling the face of a cat, hence the name. The fruit may have deep grooves, indentations, or protrusions, giving it an irregular and misshapen form. This can make the tomato less appealing and aesthetically pleasing.
In addition to the puckered surface, catfacing can also cause the fruit to have bands of tan-colored scar tissue running across the blossom end. These scars can further contribute to the distorted appearance of the tomato. The scar tissue is a result of the fruit’s attempt to heal itself after experiencing damage during growth.
When observing a tomato affected by catfacing, it is important to note that the severity of the disorder can vary. Some fruits may only display mild catfacing, with slight puckering and minimal scar tissue. On the other hand, more severe cases can result in highly distorted tomatoes with extensive scar tissue.
To better understand the cause of catfacing, it is important to consider the role of pollination and fruit development. Catfacing occurs when there are disruptions or abnormalities during these processes, often due to environmental factors.
One of the main causes of catfacing is cool temperatures during flowering and fruit set. When temperatures drop below a tomato’s optimal range (around 60-70°F or 15-21°C), it can interfere with proper pollination. This can result in incomplete fertilization and subsequent fruit abnormalities, including catfacing.
Another factor that can contribute to catfacing is excessive rainfall or moisture. When tomatoes receive too much water, it can cause the fruit to expand rapidly, leading to uneven growth and the formation of puckered surfaces. Similarly, fluctuations in moisture levels can also contribute to catfacing. For example, if tomatoes experience alternating periods of drought and heavy rainfall, it can disrupt fruit development and contribute to the disorder.
Furthermore, certain tomato varieties may be more prone to catfacing than others. Some heirloom varieties, in particular, are known to be more susceptible. This is because they often have larger fruit sizes, which make them more vulnerable to irregular growth and development.
In my personal experience, I have encountered catfacing on tomatoes several times. One memorable instance was during a particularly cool and wet summer. The tomatoes in my garden displayed varying degrees of catfacing, with some fruits having only minor puckering and scars, while others were severely distorted. It was disheartening to see the imperfect appearance of the tomatoes I had eagerly anticipated harvesting.
To overcome catfacing, it is important to create optimal growing conditions for tomatoes. This includes providing consistent temperatures within the suitable range, ensuring adequate pollination, and managing moisture levels effectively. Planting in raised beds or using plastic mulch can help regulate soil temperature and moisture, reducing the risk of catfacing.
Catfacing on tomatoes is a disorder that results in puckered surfaces, distorted shapes, and scar tissue on the fruit. It occurs when weather conditions, such as cool temperatures and excessive moisture, disrupt proper pollination and fruit development. Understanding the causes of catfacing can help gardeners take appropriate measures to minimize its occurrence and ensure healthier, more aesthetically pleasing tomato harvests.
