The Early Day Motion on the Great British Elm Experiment was tabled by Bob Russell MP and has been signed by MPs including All Party Parliamentary Gardening and Horticulture Group chair Ann Cryer.
It follows the launch of the project - which is run by the Conservation Foundation - in 250 schools across the country.
The first 250 schools to join The Conservation Foundation's Great British Elm Experiment received their young tree during the first week of March.
Pupils will be monitoring and caring for an elm tree from a sapling upwards in an experiment to unlock the mystery of why some trees survived Dutch elm disease which is estimated to have killed 25 million elms from the 1960s onwards.
Schools will be asked to log their tree's progress over the years on The Conservation Foundation website.
Height, girth, biodiversity and any signs of Dutch elm disease will be recorded and it is hoped that a new generation of elms will become established throughout the country.
The new national elm planting campaign is using young trees propagated from mature healthy native elms which The Conservation Foundation has discovered still growing in the English countryside. It is part of the 30th anniversary celebrations of Elms Across Europe, the project which led to the setting up of the Foundation by David Shreeve and David Bellamy in 1982.
