|What soil temperature is required for yucca seed germination and what is the length of germination required?
|Yucca seeds have a hard outer coating so either soak the seeds in warm water for 24 hours, or nick the outer coating before planting the seeds.
They need heat to germinate, about 70F degrees, so find a source of constant heat, such as the top of the refrigerator, or on top of a heating cable used for seed starting.
Germination usually begins within 2 weeks, but it could take over two years for the process to be completed. Since these guys aren't in much of a hurry to sprout, hope you have a lot of patience! Once they've grown their first set of leaves, the heat can be turned off and they can be transplanted outdoors.
