Post-Storm Flooding and Your Landscape
-leaf yellowing or browning
-leaf and stem wilting
-stem and limb die-back
Wet soils are also favorable for a number of soil-borne root and crown rots including Fusarium spp. and Phytophthora spp. These organisms are responsible for a number of root and crown rots that are potentially fatal. Keep a watchful eye on your landscape after flooding for symptoms that often look similar to drought stress like wilting or a dull appearance to leaves. Contact Extension if you suspect these infections as there are different control and sanitation methods that may help manage the spread of the organisms. Different plant species and root and crown rot species call for different responses that would be too numerous to explore here. So, keep an eye on your landscape and an umbrella at the ready.
Finally, this post mainly addresses freshwater flood impacts. If you have experienced salt or brackish water flooding you will want to flush the plants root zone and rinse the plant with fresh water once the salt water recedes. Carefully wash away sediment and debris as well. After a thorough rinsing and flushing use the above methods to promote drainage and aeration as much as possible.
Good luck- and consider this a warning from Mother Nature. Be sure to have a hurricane plan in place for your family, pets, property, and landscape!
