Agave Lophantha Germination

Agave lophantha, native to south Texas and the Chihuahuan Desert, is a perennial succulent plant that makes a dramatic statement in the landscape. Hardy to U.S. Department of Agriculture plant hardiness zones 8 through 11, Agave lophantha can be propagated by germinating seeds.
  1. Preparation

    • Agave lophantha seeds are planted in a lightweight, well-drained medium consisting of half inorganic matter such as pumice or perlite and half organic matter such as compost or peat moss. The potting medium is placed in a wide, shallow container or planting tray.

    Germination

    • Agave lophantha seeds are scattered over the surface of moistened potting medium, then covered lightly with a thin layer of coarse sand. The tray is placed outdoors in bright, indirect light. Agave lophantha seeds germinate best when nighttime temperatures are between 65 and 70 degrees Fahrenheit. Seeds usually germinate in two to three weeks.

    Preventing Problems

    • The seed tray is covered with clear plastic to keep the seeds warm and moist during the germination period. Once the seeds germinate, the plastic is removed, as too much humidity will rot the seedlings. Proper moisture level is crucial. The potting medium shouldn't be soggy but should never be completely dry.
