Golden Sunlight' requires an acidic medium. Consumers can acidify soil by using aluminum sulfate at a rate of 1 pound per 7 gallons of water. New flowers on big-leafed hydrangeas like 'Golden Sunlight' develop directly under the old flowers of the previous season's growth. Any pruning, which is usually only done to control height, should be done immediately after flowering. There are no major pest problems.
Plants produce attractive white to light-pink petals at the edge of darker pink flowers.
This is the first golden-leafed hydrangea on the market.
