Gardeners are being offered half-price allotments in a bid to improve their eating habits - but current users have complained the council is neglecting their plots.
Harrow is inviting health-concious residents to snap up 300 allotments at a discount rate, but environmentalists and plot holders feel their current plots are being left to decay.  
Mike Beech, of Dorish Drive, Harrow, has owned an allotment at Streamside, in Whittington Way, Pinner, for 25 years. He has seen areas of his allotment site which are inaccessible because overgrown shrubbery.
The 63-year-old said: "The council used to cut the grass twice a year, but this year it hasn't been cut at all.
"The council talks about getting people involved, but it doesn't put the money where it should. I enjoy having an allotment but there is no support."
More than 1,000 people within the borough rent allotments from the council to grow fresh fruit and vegetables. The borough has 33 sites, providing 1,325 plots over 39 hectares.
Georgia Weston, of Harrow in Leaf, an umbrella organisation for horticultural and allotment groups, said: "I would like to know where the money they are spending is going.
"We get our representatives calling up and complaining. People have requested plots and been told there is a waiting list and our records show there are ones available.
"In one case a man who owned an allotment had died and the council records said he was still using his plot.
"It [the half-price scheme] is a good idea, but there are a lot of management issues that need to be addressed."
A resident of Nelson Road, who did not wish to be named, was recently offered an allotment at Pleasant Place, in Shaftsbury Avenue.
She said: "The council sent us a key and said go and take a look and see if you want it, but it is a bit overgrown.
"When I got there I didn't need the key as the door was hanging off the hinges. It's out of control."
She is now waiting to see if the council will tackle the overgrowth on the 21-plot site before she accepts the plot.   
Councillor Susan Hall (Conservative), portfolio holder for environment services, said: "Each year, Harrow Council spends approximately s20,000 on allotment maintenance.
"However, we are aware that we need to invest additional resources in this service and have recently drafted our first allotment strategy.
"We are committed to upgrading this service."
