The call was made by Clive Knowles, chairman of the British Ironwork Center and Sculpture Park.
People have ten days to bring all sorts of medical supplies to the Palm House in the center on the main A5, near Oswestry.
Clive, 60, said: “The greenhouse will be open 24 hours a day so people can drop off supplies.
“We are open seven days a week on site and the Palm House will also be open in the evenings.
“We have already completed a week where we collected clothes, dried food, sleeping bags, wheelchairs and strollers.
“We filled an articulated truck with food, medical supplies and clothing on Friday.
“We now hope to fill a transit van which we will then organize to travel to the eastern region of Poland where it can enter Ukraine and where volunteers are available to ensure vital supplies reach trouble spots in Ukraine.
“The variety of medical supplies needed includes everything from wheelchairs to eyewashes and antiseptics to bandages, in fact anything and everything that is new and sealed.
“Second-hand wheelchairs and crutches are fine, but anything else must be sealed.
“We are trying to send the message to people that medical equipment is absolutely necessary.
“We have contacted Shropshire Council to help in this way via social media and have also enlisted the Royal Shrewsbury Hospital, Princess Royal Hospital and Oswestry Orthopedic Hospital to help with supplies.
“We are also reaching out to community groups, Rotary groups and schools to help with donations.
“There is a ten-day window during which supplies can reach us and that ends on March 24, so we hope that as many people as possible will answer our call.
