I just brought my hibiscus plants outdoors for the summer (three to four feet tall). It has been bright and sunny outside. The leaves are suddenly turning a bit white and wilty looking. Could the sun be too much of a shock for them after being indoors?

Your plant is suffering from stress and possibly too much light as a result of its new outdoor environment. They should always be acclimated to their new environments to reduce the amount of stress while they adapt to their new surroundings. Try reducing the amount of light and slowly give it more once it has acclimated.
