impacts on neighbouring plants. A decurrens i've found tends to retard
growth of neighbouring plants. The best species i've found as pioneers for
fruit trees are the smaller wattles (they're also easier to remove when
their life span or function has reached use-by) include A. florabunda, A.
saligna and A. fimbriata.
As a smaller shrub legume for mulch I've found pigeon pea to be a great
sub-tropic substitute for tree lucerne
