"Each day they would water them with their watering cans and watch them grow, so they were really sad this morning when they came down and they were all gone."
Miss Collings said the centre would be considering increasing its security.
"We are thinking that we might have to put a lock on our gates.
"We've never been broken into here before. It's an early childhood centre and so many of them do get ripped off. It's just not fair."
Miss Collings hopes those responsible for the theft will return the planter boxes. "It's not fair on the children that planted all the flowers and now they're just ruined. "It's so sad that people can do these terrible things to places in our community, especially when it affects children and makes them upset."
A hose and hose connections were also stolen. The burglary is thought to have occurred on Sunday night.
