Depending on whom you ask, it is either considered pretty, with its dainty flowers, or pesky, a troublesome weed in many Florida lawns.
Blowing in the Wind?
Part of what makes Florida pusley so persistent, is the same feature many find attractive—its proliferation of flowers. These flowers, however, very quickly produce seeds; and, in a matter of just a few weeks, what was once only a small patch of delicate flowers in your lawn has taken over half the yard!
One interesting note about Florida pusley (Richardia scabra) is that there are two other closely related species. One has larger blooms which can be pink, blue, or violet, and is R. grandiflora, aka, largeflower pusley. The other, R. brasiliensis, has thicker roots. Both species reproduce by both seeds and stem/root sections.
Regardless of the species, however, weed control for Richardia requires some amount of patience and persistence. Control recommendations include:
- frequent mowing to interrupt the life cycle and prevent flowering and seed-set;
- use of pre-emergent herbicides to inhibit seed germination; and
- careful selection of broadleaf post-emergent herbicides.
Prevention is always better than a cure. Following research-based turf management practices helps lawns to maintain vigorous growth which deters weed infestations.
