The unseasonal weather has forced Yorkshire in Bloom to cancel judging through the Easter holidays.
Normally, its spring round of judging runs up to April 12 and the cancellation is a first.
Brendan Mowforth, chairman of Yorkshire in Bloom said: “The decision has not been made lightly, and is based on the prolonged severe weather conditions that we are currently experiencing.
“In the last 12 months gardeners all over Yorkshire have been challenged to the highest level.”
Mr Mowforth said gardeners had to contend with flooding, snow, severe frosts and freezing easterly winds through autumn, winter and now spring.
“I am aware that many of our entries are extremely concerned about the current ongoing weather conditions and that they may not have anything to show judges during this spring judging period,” he said.
“In view of this, the executive has agreed the best move is to cancel spring judging and that the Yorkshire in Bloom Awards this year will be based on the summer judging only, which will take place from July 1 to 19.”
There are almost 180 entries for 2013 and each is usually judged twice during the year with the aim of showing the effect of work being done all year round.
