Stormwater Ponds: Plant at the Right Time of Year

  • Last spring frost through summer is GOOD 
  • Winter planting of shallow water plants is BAD

 

Plants installed above the normal water level may tolerate winter planting.  Emergent (shallow water) plants RARELY survive  winter planting.

Midsummer plantings during droughts may need irrigation for 6 weeks while the plants establish themselves.  The soil needs to be kept moist, not flooded during this period.

If forced to install shallow water plants in winter, keep the water drained down below the soil surface for at least 6 weeks, and budget for replanting in spring.
