The waterway pest
Water hyacinths are beautiful plant with a pretty flower that can go really bad as it spreads so fast you can almost see it grow. It creates dense free-floating mats and can root in the mud if necessary to live.Yes…it is invasive nuisance, but not illegal to buy for your pond in most places. At this time 3 states prohibit its sale. It does not survive the cold weather so the northern climates are free from its “clogging” behavior.
ORGANIC AND BIOLOGICAL CONTROL:
- Don’t put it in your water, but if you have it, pulling it out by hand is easy. Place the removed plant in a plastic bag, seal it and trash it.
- Manatees eat it but you can’t bring manatees to your waterway easily or legally.
- Three insects and a moth are known to eat water hyacinth and are used to control and manage extreme situations, however there is question whether this has introduced another invasive incidence.
- A foliage spray can be used to kill it but beware…be careful as it could harm other plants.
