- 1). Check marigold plants daily or every other day for spent blossoms. You should start this a week or two after planting.
- 2). Look for flowers that are withered and not just brown and dry. Deadhead any blossom that is done performing. Watch for entire sections of the plant that are withered and dying. Remove anything that is turning brown or not developing properly.
- 3). Grasp the flower head at the base between your thumb and forefinger.
- 4). Snap the entire flower head to the right or left and remove form the plant. Do not just remove the flower petals as this will not remove the developing seed head. You must get the entire flower for the deadheading to be productive.
- 5). Look for signs of insect damage and remove those heads or plants as well. Getting rid of insects early can prevent infestation.
- 6). Be sure the flowers you are pulling off are truly finished. Marigolds will close a little bit in the evenings and be fully open in the daytime. Do your deadheading in the morning when flowers are full and vibrant.
