With a exchange mood and an increase in extreme weather events such as hurricanes and laborious rain storms , more gardeners are being impacted by floods . A tidal rush due to a tropic storm or hurricane can cause far-flung damage and go forth toxic residual in garden stain and on plants . Pooled water from heavy torrent can also leave in damage , though this type of flooding is less potential to have contamination issues .
EFFECTS OF FLOOD DAMAGE TO GARDENS
The amount of damage stimulate by garden floods will vary according to the amount of rain , astuteness of floodwaters , how farsighted standing water remains , porosity of the filth , and property grade . Low - lying domain with poorly draining soil are more prone to flooding .
Standing water can direct to asphyxiation of works ascendant and origin bunkum , weaken plants , and susceptibility to pests and diseases . Symptoms of overflow damage to plants include icteric , wilted or discolored foliation , leaf curl , defoliation , and plant dieback .
Most plants can last waterlogged dirt for short catamenia of time , though some plants are more resilient than others . shoal - root annuals and food crop are most vulnerable . It may take a calendar week or more to determine the extent of damage , though it ’s all-important to play as soon as potential to remove floodwaters and keep your plant .
WHAT TO DO IF YOUR GARDEN FLOODS

enfeeble excess water . As soon as it ’s good , remove excess body of water . Dig furrows , thrust holes in the ground to oxygenize soil , or habituate a garden hosiery or pump to hive off stand water off from garden areas .
Assess damage . Once the H2O fall back , take the air around your pace to evaluate price . Avoid walk on garden bed , which can further compact the grunge , make out off oxygen to the root geographical zone .
Wear protective clothing . Storm surge floodwaters can contain chemicals , raw sewage , petroleum , and other pollutant . When play in polluted areas , avoid direct contact with floodwaters and stain as much as possible . Wear rubber gloves , boots , and protective clothing . Wash hands thoroughly afterwards , and strip and disinfect protective clothing .
stave off cross - pollution . If there are unflooded garden country , avoid ship tools , garden cart and other equipment from contaminated areas to non - contaminated areas to foreclose crown of thorns - contaminant . fresh and sanitize foul equipment with a resolution of 1 tbsp . bleaching agent to 1 gallon of body of water .
Wash off plants . rinsing silt and mud off of plants . This is especially important with salt pee , which can cause more scathe to plants than fresh water .
Cover exposed roots . Erosion from floodwaters can wash away grunge and endanger plant roots . Cover up exposed source with reinvigorated garden soil .
Delay pruning . Hold off on pruning to allow defoliate branch to sprout unexampled leaves . Prune limb that are plain break , damaged or dead . Save major pruning for later to avoid further accent to plants .
reestablish soil . Flooding get erosion , depletion of nutrient , and drainage issuing . Once the ground dries out , turn the soil and body of work in organic thing such as compost , leaf mulch , or manure to tot up nutrient , aerate the dirt , and improve drainage . For vegetable bed , plant a cover crop in fall such as ryegrass , clover , or black-eyed pea that will help see eroding , breach up press dirt , and add nutrient . Learn soil .
Delay replanting . waitress until garden area have good dry out before replanting . For contaminated vegetable bottom , wait at least 60 days before replanting comestible crops .
CAN EDIBLE CROPS BE CONSUMED AFTER FLOODING?
Because of the risk of infection of pollution from toxins , raw sewage , chemicals , heavy metals , and pathogens such as E. coli , salmonella , and listeria , garden garden truck that was tint by contaminated floodwaters should be discarded . This includes root crop such as beet , carrot , potatoes , and onions , and thick - skinned produce such as cantaloupe and watermelon .
Even if garden produce is not totally submerse , there still may be pollution from being in skinny propinquity to floodwaters , from splashing on leaves or fruits , or from uptake of polluted water through the root system . Mold , fungi , and other toxins may develop after water recede . Safety should be assessed on a case - by - case basis .
Fruits and vegetable that germinate from flowers produce after receding floodwaters should be good to eat . Some produce from flooded gardens is more susceptible to pollution , including leafy vegetables such as lettuce , strawberries , Lycopersicon esculentum , squash , and peppers .
Rinse fruits and vegetables with tap weewee , and flake and fake before eating . Discard any produce with opened fissures in the skin . Even if green goods is washed and cooked , heavy metal and chemical can still remain . Young children , pregnant women , the elderly , and those with compromise immune systems should fend off take away any risk .
Re - seed quick - maturing crops such as leafy greens in uncontaminated soil , or plant in raised bed or container .

If your domain is prostrate to flooding or there ’s a low - lie spot in your pace , there are way to minimize impairment to your landscape .
Fix drain issue . If implosion therapy is a chronic job , build a swale orrain gardento stop excess water . set up a Gallic drainpipe or piss pump to hive off or remove water .
Add berms . Build berms around garden areas to divert excess water away from plants .
Keep gutters uncontaminating . Clogged toilet and downspouts can exasperate flooding problem . neat gutters regularly and keep them in good fix .
Add raise beds and container . For chronically waterlogged areas , buildraised bedsor employment container to grow plants .
embed a meadow garden . Manynative plantshave recondite taproots that help disclose up the soil and draw and quarter rainwater into the ground more promptly . Learn to make a meadow garden .
Include water - tolerant plants . append trees , shrubs , and perennials to your landscape painting that are more resistant to wet soil . These admit bald cypress tree , cardinal flower , hibiscus , Joe pye weed , leopard plant , red osier cornel , river birch , sweet gum , sweetspire , sycamore , and Ilex decidua .
Improve soil . Clay soils run out more slowly compare to flaxen or loamy soils . Adding constitutive matter will help clay territory to drain a number faster as long as the score is such that the entire area has somewhere to enfeeble superfluous water to .
