Poinsettia 'Green Envy'

Summer Growth: Water and fertilize with a balanced houseplant fertilizer every 3 to 4 weeks during spring and summer as new green leaves emerge. You can move it outdoors to a shady spot after the last frost passes

Encouraging Color for Next Christmas: Starting in late September or early October, give the plant 14 to 15 hours of total, uninterrupted darkness every night (by placing it in a dark closet or covering it with an opaque box) and bright light during the day for about 8 to 10 weeks
