Plot holder Ted Hitchmough has lost all of his crops
Flash flooding and poor drainage at allotments in Wavertree have destroyed a year's worth of crops.
Thingwall Road Allotments in Wavertree have seen over 30cm of water in recent weeks after flash flooding.
Plot holders believe the site, which has four wells and three underground springs, has been affected by the demolition of local buildings.
Chairman of Thingwall Allotments Ron Lamb said "We think that the water has been directed onto our allotments."
"A lot of people have lost their crops due to the flooding. They worked all year for this and it is all under at least a foot of water," he told BBC Radio Merseyside.
Ted Hitchmough who has had an allotment for almost 20 years at Thingwall said "I've lost almost everything, potatoes, cabbages, everything that I've been growing to eat have gone.
"All my fruit trees have gone, there's very little left.
"We've got a show in a fortnight and I've got nothing to show."
Flash floods have destroyed David Mason's plot at the Thingwall Road site
Weather conditions throughout the summer have proved tough for gardeners. A very dry June led to a hosepipe ban in Liverpool and very dry ground.
When intense heavy rain fell in July the combination of dry ground, poor drainage and run off from concrete surfaces led to flooding at the allotment site in Thingwall Road.
Plot holder Sarah Mason, who shares an allotment with her brother David said, "It's saddening the amount of time and money you put into it just to rot in front of you.
Chairman of Thingwall Allotments Ron Lamb added, "People are getting really despondent.
"They want to walk away but that's not the answer.
"The answer is to get the drainage sorted out.
"We think United Utilities should come and look at this. Since the council has changed we haven't seen anybody. We're not giving up."
