Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Extension.org has several fact sheets that address how to deal with the aftermath of flooded landscapes. Although things may look horrible, many plants will survive after being flooded and submerged. You can take some steps to help them.
If your plants are covered with silt, you need to give them a bath. First wet the plants with plain water. Next use your pump up sprayer to cover the plants with water containing one tablespoon of dishwashing liquid per gallon. Add a teaspoon of dishwashing liquid to a gallon of water in your sprayer and spray the plants. The dishwashing liquid will help dissolve the sticky silt. Work in small areas .Wait for one minute and rinse with clear water from a hose. Don’t be tempted to use a high pressure spray which can injure the plant’s cells.
