A representative said: "April has been very dry as was March. Water companies are confident that there will be enough water to avoid restrictions through spring and summer although we may have to speak to farmers about the use of water in some agricultural practices.
"If the very dry weather continues we may look at preventing farmers taking water from rivers to irrigate their crops. We are working closely with the water companies and with the Met Office, and will monitor things to ensure supplies are not disrupted."
United Utilities has said reservoirs across the North West are 90 per cent full on average so there are no plans for hosepipe bans despite April having just 21 per cent of expected rainfall.
Growers said conditions would be a challenge and could mean retailers have to replace guaranteed plants.
