We are renovating a pasture and would like to frost seed.
Last year we successfully frost seeded clover. Are there any
other legumes, or any grasses, that can be frost seeded?
Thanks for the question on frost seeding. The idea of frost
seeding is to get your seed out onto the soil as early as
possible following snow melt. Once the seed is on the ground,
the freezing and thawing action that takes place near the
soil surface this time of the year, (when the sun thaws the
surface during the day and at night it refreezes), actually
pulls the seed into the cracks and crevices that appear.
Given that theory, any seed that can tolerate cold temperatures
could be frost seeded. We frost seed alfalfa, orchard grass,
brassicas, oats, field peas, etc. We tend to frost seed these
crops into existing crops like fall-planted wheat or what
you suggest, pasture renovation. There may be many other crops
that will work in a particular area or region. Figure out
what you need in your mix, knowing that any cold-tolerant
crop will work, that is, any crop you would normally want
to plant first thing in spring.
