50 Seeds Cardinal Climber Vine White Flowers Morning Glory Seeds HOW TO PLANT Seeds may be scarified, but not a requirement. To scarify, you may nick the seeds with a knife, or rub the seeds with sandpaper or a file. Then soak the seeds overnight. Plant seeds 1/2 inch deep and provide 8-12" spacing between plants. Once vines reach 6 inches, provide trellis support unless planted in hanging planter in which case you can leave it to spill over. HOW TO CARE FOR Water weekly at first or when the soil looks dry. Once established, only water as needed. Remove any spent blooms as they appear and at the first sign of killing frost, cut back dead vines.
