What is the trick to growing sunflowers?
Plant sunflower seeds 1 to 2 inches deep after the last threat of frost. Space seeds 6 inches apart for smaller varieties and 12 inches apart for taller varieties. Once seedlings emerge, be sure to thin out as needed. Rows need to be spaced 2 to 3 feet apart. Only larger seeds with tough exterior coatings should be soaked. Tiny seeds with thin outer shells do not require soaking. Soaking tiny seeds can cause them to clump together, making them almost impossible to sow.Soaking them in water softens the hard seed coat, exposing the embryo to moisture and kickstarting growth. Sunflower seeds don’t need to be soaked before planting—after all, the seeds split easily—but soaking them for 12 to 24 hours will hasten germination and increase the number of seeds that sprout.Soaking them in water softens the hard seed coat, exposing the embryo to moisture and kickstarting growth.

Some, like onions and parsnips, are viable for only a year or two. Others, like squashes and tomatoes, last longer, for 5+ years.Seed life can be maximized by Freezing – which will increase shelf life 4-5 times. Do not refrigerate. Refrigerators humidity fluctuates too much and can shorten the life of your seeds. If freezing – avoid condensation – which can shorten a seed’s life.
