Tips to Grow Larkspur

  1. Arrange good quality larkspur seeds.
  2. The soil should be evenly moist, rich, well-drained, slightly alkaline.
  3.  Plant your seeds ¼ inch deep in a container and place the container in a plastic bag.  Refrigerate for 2 weeks. After 2 weeks, remove the container from your refrigerator and place it in a sunny window in a cool room. 
  4. The seeds should germinate in 2 to 3 weeks. The seedlings need temperatures below 55⁰F so keep them in the cool room until you are ready to transplant them into your garden after your last frost. Transplant carefully trying not to disturb or injure the taproot.
  5. We can add compost and can spread Mulch lightly around the plants to retain moisture for better growth.
  6.  harvest the flowers when 1/3 of the flowers are open on the stalk. Keep them cool until you are ready to use them. They will last 5 to 7 days in a vase.
