Salmon, a former tennis coach, said the LTA sent an email about ending the competition, and described the decision as a surprise.
“There was an email in October which went to the men and women captains of each county, saying last November’s event would be the last ever.
“It was a bolt from the blue for players, captains and supporters. We were all asking the question of why.”
The following day, Salmon set up the “Friends of County Cup” Facebook group, to “celebrate” county tennis.
“We all feel the LTA should have consulted everyone before making a decision with key stakeholders, ex-players, captains and supporters,” he added.
