A tomato plant is just like any other type of plant and it can get a disease that is likely to kill the tomato plant if not properly cared for. Just like people, tomatoes are prone to getting various ailments and diseases so proper care of a tomato plant is vital. Gray wall is one of many diseases associated with a tomato plant and it can be very fatal to the tomatoes. Gray wall is a disease that affects the tomato itself during the ripening process and it is exhibited through appearance. A tomato that is suffering from gray wall will show various symptoms throughout the ripening stage and it can kill every tomato you have. If you have a tomato plant and want to keep it healthy, then you should know about a possibly damaging disease called gray wall.
Gray wall is a disease that affects the tomato during the ripening process and it can lead to a barren tomato plant if not managed. Gray wall is damaging because it affects all aspects of the ripening process and can make your tomato useless and can infect every tomato. A tomato suffering from gray wall will show symptoms and they are very specific to the gray wall condition. Gray wall will make the green tomato appear gray or have spots of gray on it which happens before the tomato is ripe. If you have a ripe tomato infected with gray wall then it will appear on the inside and not the outside. The ripe tomato will have green spots or brown spots inside of it and it will appear mushy and softer than it should. The gray wall will basically make the tomato ripen at an uneven rate which is why some areas appear too ripe while other areas of the tomato appear normal.
Gray wall can be found anywhere in the world where tomatoes are grown but mostly occurs when a tomato is in the wrong environment. Gray wall does not affect the foliage of the tomato plant which is what makes it so characteristic since it only affects the tomato. There is no real cure for gray wall disease except using a disease-resistant variety tomato plant for your specific location. Since there is no real cure for gray wall, prevention is the best method of treatment and is mostly common sense. You should provide your tomato plant with a good growing environment and make sure you follow the recommendations on the plant. The tomato plant should not be too heavily shaded and it needs a large amount of sunlight to cut down the risk of the disease. A tomato plant should also be watered evenly and a proper amount of water should be used to decrease the chances of gray wall disease. The fertilizer and soil also should be loose around the roots of the tomato plant and it should not be too compact. A tomato plant might also be susceptible to gray wall disease if you live in a cooler climate so it is important to be in the right region. Some tomato plants will get gray wall for no apparent reason and some are just unhealthy to begin with which makes them more prone to certain diseases like gray wall. Overall the best thing you can do to stop your tomato from getting gray wall is to provide the right environment for the plant and keep the soil loose around it.
