Floods

COPING WITH A FLOODED GARDEN
More and more people are getting concerned about flooding and the damage it causes. No house is really safe, although the severity of the floodwater will differ depending on where you are. Although we escaped the severity and distress of the damage, there have been floods in Inishowen with Greencastle being the worst hit. The issues of why this is happening are open to debate…Global Warming and the fact that we have been building on flood plains are just two theories. Whatever the reasons our hearts go out to the families who have been so affected by the floods. When the waters recede and it is time to clear up and count the costs there will also be some work to do in the garden.

HERE COMES THE FLOOD
I used to live in an area where the bottom of the garden got washed away every year. It wasn’t that the area was low lying though, it was because the storm drains were not sufficient to carry away the water fast enough. The result was the manhole covers used to pop off of the drains and the water would come out like a very powerful fountain. It wasn’t just the water of course as the drains were also linked to the sewage pipes. Having sewage in the water is why so many household items have to be dumped. Veggies contaminated by sewage couldn’t be eaten either.

AFTER THE FLOOD

After the water level has gone down there are some steps you can do to bring the garden up to scratch.

· Add some slow release fertiliser or well-rotted manure to the soil (beds and lawn) as nutrients will have been washed away. Don’t disturb unti it has dried, then gently aerate the soil with a fork.
· Put some coarse lime-free sand into the holes as well to aid the drainage.
· Most garden plants will survive a day or two under water so don’t panic and start digging everything up straight away.
· Wash down hard surfaces and collect up debris to prevent drains blocking, soil surfaces being covered, and pollutants or contaminants lingering in the garden. Wear gloves and overalls to minimise contact with pollutants.
· Remove damaged shoots from affected plants.
· Consider planting trees on a slight mound.
· Grow plants in raised beds.
· After flooding, edible crops near to harvest are best not eaten: no assurances can be given that root crops will be safe to eat, so they should be discarded. Plants eaten raw should be discarded too, and it is prudent to avoid growing salads and other uncooked crops for two years in case disease spores remain in the soil. However, the following year after flooding, it should be safe to grow crops that are to be cooked.
· If you know in advance that a flood is coming then try to gather everything from the veggie patch that you can before it comes.

Here are a few other things you can do:

· Roofs converted into living green roofs absorb storm water and release it slowly.
· Move any items kept outside such as garden furniture to higher ground. Remember that floodwater could get into your garage so move any chemicals or fuel to ensure that they do not spill into the floodwater and cause damage.
· Close off the flow valves on propane tanks, oil drums, or other fuel containers that supply your home through pipes and fittings.
· Unplug any exterior electrical connections such as outdoor lighting, pond pumps and filters.
· Turn off the water supply to the garden.
· Tie in climbing plants.
· Check tree ties are secure on any newly planted trees.
· Anchor fruit cages and coldframes against storm damage or dismantle them if time permits.
· Take valuable or sentimental items and store them indoors or move them to higher ground.
· Empty petrol lawn mowers.
· Lock gardening tools away.
· If there is somewhere for water to go, drainage can be installed. Or, where appropriate, it may be worth digging out a ditch or seasonal pond at the lowest part of the garden to catch surplus water and let it soak in slowly.
· Choose permeable surfaces when laying drives, paths and patios to allow rain to soak in.

REMEMBER:
Floodwater will often be contaminated, usually by untreated sewage, spilled chemicals, silage from farms or dead animals.

· Always wear protective clothing when working in or near floodwater.
· Wash all cuts and cover them with waterproof plasters.
· If you receive a wound during a flood you should go to a doctor and get a tetanus injection.
· Small children, pregnant women, elderly people and those with mobility difficulties or other health problems should be kept away from floodwater.
· If you feel unwell at any stage or if you ingest floodwater you should contact a doctor.
