Flower arranging and designing will help you make more profit from your greenhouse. Some of the flowers and foliage you use can be grown in your greenhouse or garden—other material will have to be purchased—preferably from a wholesaler, if one is accessible to you. New Year’s Day, Valentine’s Day, Easter, Mother’s Day, Decoration Day, Thanksgiving, and Christmas are the big holidays when cut flowers, arrangements, accessories, greens, and corsages are in greatest demand. But there is also year-round trade for birthdays, parties, showers, weddings, and funerals.
