Answer: Herbs are like most other plants. They like a deep soaking and then want the soil to dry out a bit before being watered again. Depending upon the weather and the size of the plants you probably need to water once or twice a week. You can stick your finger down into the soil when the top of the soil is dry. If it is moist 2 inches below the surface, you won't need to water for a few days; if it is dry, it is time to water. Soak the soil thoroughly when it is time to water. I've had parsley leaves turn white, too. I just pick them off the plant. It can be caused by sunscald or nutrient deficiency. If the rest of the plant looks okay, it's sunscald. If the rest of the plant looks pale, you are either overwatering or your plants need to be fed. Best wishes with your herbs!
