Queen Anne’s Lace Sun or Shade

Starting Queen Anne’s Lace Indoors
It’s usually not a good idea to start Queen Anne’s Lace indoors since it can be hard to transplant without damaging its delicate root system.
However, if you live in an area with a short growing season you can start Queen Anne’s Lace seeds indoors in a heated seed-starting tray two weeks before the last frost in your area.
You want to use a loose potting soil mix that has excellent drainage. It’s also important to not plant Ammi Majus seeds too deep to avoid poor germination rates.
Once the seeds are planted keep the soil moist and make sure the tray remains covered until the seeds germinate.
Once the seedlings start to emerge you can move them to a warm sunny window, or you can place them under an LED Grow Light (Buy Online) until the soil thaws out in your area.
Once the seedlings have two full sets of true leaves you can start to slowly harden them off by setting them outside in the sun for a couple of hours a day before carefully transplanting them into your garden.
