I have a new raised bed and five transplanted tomato plants. The leaves are curling upwards and they have small brown spots on the leaves and stems. It seems to be spreading to all plants. Can they be saved or should I pull them?

Curled or cupped leaves are not anything to be concerned about. The condition appears to be more common on staked and pruned plants and occurs when excessive rainfall or overwatering keeps the soil wet for extended periods of time. It is also related to intensive sunlight which causes carbohydrates to accumulate in the leaves. Some varieties of tomatoes have characteristically curled leaves. Your plants should continue to produce fruit with or without curled leaves. Small brown spots can indicate insect feeding or might be the early signs of a fungal infection. If the spots enlarge or if unaffected leaves begin to develop spots, a fungicide applications might be required. Best wishes with your tomatoes!
