What it looks like: Mature tomato plants suddenly curl their leaves, especially older leaves near the bottom. Read more on learning to eat ugly produce! 7. Catfaced tomatoes are safe to eat simply cut away the scarred areas. Black plastic can be used as a temporary measure until the temperatures warm up enough that it’s no longer needed. As the plastic heats during the day, it releases the heat back towards the plants at night. Using black-plastic spread on the soil can also help. Devices such as a “Wall of Water”-a circle of water-filled plastic tubes-raise temperatures near the tomato and help keep them high enough on cold nights to prevent cold-related problems. Make sure the weather has truly warmed up enough to support proper tomato development. What to do about it: If possible, plant tomatoes a little later in the season. This creates the lumps and bumps typical of catfacing. However, if the flower is pollinating before the petals begin to drop off, some stick to the developing tomato. Blossoms fall off when temperatures drop too low. What causes it: Plants pollinated during cool evenings, when the temperatures hover around 50 to 55 degrees F, are subject to catfacing. The blossom end is rippled, bumpy and lumpy. What it looks like: Catfacing makes tomatoes appear deformed. Water plants regularly at the same time daily to ensure even application of water. Apply it early in the morning or late in the day - if sprayed onto leaves midday, it can burn them. A foliar spray containing calcium chloride can prevent blossom end rot from developing on tomatoes mid-season. Adding crushed eggshells to your compost pile can also boost calcium naturally when you add compost to the soil. Lime and gypsum may be added for calcium, but they must be added in the proper amounts depending on your soil’s condition. Tell them you’ve had problems with blossom end rot in the past, and they will give you recommendations on the amendments to add to your soil.
What to do about it: Before planting tomatoes in the spring, have your local garden center or Cooperative Extension conduct a soil test. Hot, dry spells tend to exacerbate blossom end rot.
Uneven watering habits also contribute to this problem. This soil pH level also makes it possible for them to absorb calcium. Tomatoes need a soil pH around 6.5 in order to grow properly. There’s either not enough calcium in the soil, or the pH is too low for the plant to absorb the calcium available. What causes it: Your plants aren’t getting enough calcium.
Tomato seedlings Patch#
When you try to cut off the patch to eat the tomato, the fruit inside looks mealy. The black spots on tomatoes look leathery. What it looks like: The tomato plants appear healthy, but as the tomatoes ripen, an ugly black patch appears on the bottoms.
