Birdsfoot trefoil is a non-bloating legume best suited
to permanent pasture situations. It is well adapted to steep
or stony land that should not be cultivated, because birdsfoot
trefoil will reseed itself. Although individual plants live
for only a few years, stands of birdsfoot trefoil have remained
productive for 10 or more years when allowed to go to seed.
It is also adapted to soils with marginal drainage. Trefoil
has a lower yield potential and is more difficult to dry
than alfalfa, so it is recommended for hay prduction only
in areas where alfalfa will not grow well.. Because trefoil
seedlings are slow to establish, it will usually take at
least a year to get a satisfactory stand. Trefoil, like
alfalfa, has a critical fall harvest period, beginning about
10 days earlier than alfalfa at the same location.
