Also know, is kale grown in water?

Water. Keep your kale plants well-watered. Along with cool temperatures, moist soil helps keep kale leaves sweet and crisp, rather than tough and bitter. Mulching under the plants will keep the soil cool and moist, the way kale likes it.

Also, how do you pick kale? Kale is ready to harvest when the leaves are about the size of your hand. Pick about one fistful of leaves per harvest. Avoid picking the terminal bud (found at the top center of the plant) because this will help to keep the plant productive. Kale will continue growing until it's 20°F.
