Why are school gardens important?

School Gradens can be helpful to students in many ways, whether it's for the classroom or for life skills. While in England i saw how the garden had helped the students compared to the students i have seen and met who do not have a graden at school or even at home. Before working in the garden many students are/ have:
Causing problems in class
No interest
Complaining
Do not want to get dirty
No motivation or attention
hard time focusing in the classroom
bad eating habits inside school as well as oustide school
Little to no physical acitivty outside of school
Low self-esteem and confidence

Not only do they learn math, english, history, art, physical education, health, etc from the garden but they also learn life skills such as:
leadership, teamwork, community engagement
better eating habits, more willing to try new foods
more physical activity
more confidence, self esteem, outgoing
therapy

According to Impact of School Gardening on Learning, "Another teacher remarked that the garden was removed from the flashing images of computers and the busyness of the classroom, and therefore gave the pupils more opportunity to be quiet and reflective. This can be seen in the following quotation from one pupil, for whom the garden provided:

A chance to get away from everyone in the classroom. They're all noisy and they ain't listening and they start shouting. And then some of us get in trouble and it’s not even us; people wind you up.

'Most of these boys come with other baggage, which is what is causing them not to be able to focus in the classroom and to display challenging behaviour. When boys have got their hands dirty they talk, they talk and get it off their chest without realising it and possibly without remembering afterwards what they've talked about. But they've gone through that process and they feel lighter because they have talked about it.'"

After working in the garden the students:
Students change their opinion of the garden being "cool"
More willing to learn and tech, help others
More focus and motivation in the classroom
Greater understanding of school subjects
Are able to step away from commotion and calmly reflect on homework, personal issues, etc.
Gives them a sense of accomplishments and a sense of purpose
