Propagation: Stratify Everything but Tropicals?, 3 by

I used to start many different seeds years ago. Now I only sow Iris and Daylily seeds from my own crosses.

Let the hardiness of the plant whose seeds you are trying to sow be your guide as far as stratification (moist cold).

The fridge can be used but take longer to work. The secret to success for many seeds is flunctuating temps with moisture--- such as Nature provides---to break the dormancy of seeds.

Another way to sow that I used with other seeds, including Daylilies---Deno Method.

Seeds with long dormancy, such as Iris, I sow in plastic shoe boxes filled with potting soil and left outside covered (or in unheated garage or shed). They will sprout in early spring when temp reaches 55-70 degrees.
