  • 146. Seed Mixes• We plant some species individually, but generally we put seeds in a seed mix before planting.• For our most recent planting, we made three seed mixes – mesic, dry mesic, and general.• If we have any questions what mix to put a species in, we refer to Swenk and Wilhelm.• To mix the seeds, we put down a large tarp, pour all the seeds onto the tarp, mix them well using rakes and shovels, and then shovel the seeds back into the barrels.
  • 147. Barrels of mixed seeds ready to plant. Photo courtesy Hank and Becky Hartman
  • 148. Restoration Planting Methods• Harvest corn in September or October.• Burn corn stubble in early November.• Spread seed mixes – general mix over the entire planting after November 15 and before the ground freezes.• Harrow the field.• Many seeds require exposure to cold temperatures for a certain period of time, and the freezing and thawing of the ground prepares the seeds for germination in the spring.• If you wait and plant in March or April then many of the seeds will not germinate until the following year.

  • 151. Overseeding Methods• Overseeding in November or December is preferred, especially if the area is burned first.• After a spring burn (March or April) – only best if there is a heavy thatch buildup and cannot do a fall burn.• Plant as you pick – violets – pick, let dry for a week so they dehisce, and then plant the next week.• Porcupine grass – pick in the morning and plant that afternoon.• Follow natures pattern by planting at the same time that the seeds would naturally fall from the plant.• This can work well, especially if you burned the prior spring or fall because there should not be a lot of thatch build up.
  • 152. Where to Collect Seeds• Seeds should be picked as close to the restoration as possible – 25 to 50 mile radius.• The genotype should be better adapted to the location of your restoration.• Most of our seeds are picked at Nachusa.• Other options – railroad and road right of ways and hillsides.• Always obtain permission of landowners or public area managers before collecting.
  • 153. Keeping Seed Records• GPS works well for tracking the exact locations of your seed sources.• Keep seed diaries that record the locations and dates that you picked a species.• Detailed records will help you remember where and when to pick in subsequent years.
