Christopher Ratten and Lindsey Cooper of Baket Tilly Restructuring and Recovery are joint administrators.
The company, which turned over £8.9m in 2013, was hit by the administration of Paperlinx, its largest supplier. It also blamed "challenges in the envelope market" and a weather-related slowdown in its horticultural market.
Mr Fothergill's Seeds commercial director Tim Jeffries said: "D&C have printed our packets. Very sad to see such a good supplier go into administration - full of excellent and supportive people.
"We have been working on alternative supplies for a while and also have plenty of packet stocks. Our packet printing business is being picked up elsewhere and our trade customers will not see an interruption of supplies."
Thompson & Morgan managing director Paul Hansord said: "Dobson & Crowther does produce a percentage of our seed packets, but we also work with several other print companies as we require such a high volume to meet customer demand, which will allow us to transfer outstanding work if needs be to ensure an unbroken supply of our retail and mail order seed. It’s a real shame to see this happen to a company that always provided us with a quality service and we hope they can resolve the issues to carry on trading in some form or other."
Suttons Seeds said: "We are obviously very sorry to see a long standing supplier in trouble. But we do however have alternative suppleirs both here and in Europe."
