Description

School gardens allow students to garden during school or non-school hours with school staff guidance, generally on school grounds. School gardens are typically accompanied by nutrition education, food preparation lessons, and fruit and vegetable tasting opportunities. School gardens can also provide students with hands-on learning opportunities in subjects such as science, math, health, and environmental studies.  

Expected Beneficial Outcomes

Increased willingness to try fruits & vegetables
Increased fruit & vegetable consumption
Improved nutrition
Reduced obesity rates
Increased physical activity
Improved health-related knowledge
Enhanced academic instruction

Evidence of Effectiveness

There is strong evidence that school gardens modestly increase participating children’s vegetable consumption and willingness to try new vegetables (Savoie-Roskos 2017, Davis 2015b, AHA-Mozaffarian 2012Langellotto 2012Scherr 2013Ratcliffe 2011Parmer 2009McAleese 2007Rauzon 2010). Establishing school gardens is also a recommended strategy to promote healthy eating, improve nutrition, and reduce obesity (CDC-School-based obesity preventionCDC MMWR-School health guidelines 2011CDC-Fruits and vegetables 2011IOM-Government obesity prevention 2009). Additional evidence is needed to determine long-term effects (Savoie-Roskos 2017, Davis 2015b). 

Gardening increases vegetable consumption among children, perhaps due to increased access to vegetables and decreased reluctance to try new foods (Langellotto 2012Scherr 2013McAleese 2007Rauzon 2010Ratcliffe 2011Parmer 2009). Garden-based nutrition intervention programs have also been shown to increase health-related knowledge, willingness to taste, and preference for fruits and vegetables (Kararo 2016, Cotugna 2012Robinson-OBrien 2009Blair 2009Ozer 2007Koch 2006Morris 2001Morris 2002Morgan 2010Gatto 2012Jaenke 2012Dirks 2005). School garden participation can also increase elementary school children’s moderate and moderate-to-vigorous physical activity (MVPA) during the school day (Wells 2014). A New Zealand-based study associates school gardens with lower BMI and reduced prevalence of overweight among children (Utter 2016).

Research suggests that short-term after school gardening activities are less effective at changing children’s fruit and vegetable preference and consumption than year-long in school programs (O'Brien 2006Poston 2005). Students participating in a school garden program as part of a multi-component intervention that includes activities such as farmers’ visits to schools, taste testing, field trips to farms, in-class lessons, and farm to school programs have greater increases in fruit and vegetable knowledge, preference, and intake than students participating in school gardens alone (Evans 2012a, Jones 2015). A UK-based study suggests that high intensity school garden interventions may be needed to significantly increase fruit and vegetable consumption (Christian 2014), and that teachers may be better able to change students’ attitudes towards eating fruits and vegetables than external gardening specialists (Hutchinson 2015). 

School gardens can enhance academic instruction (Berezowitz 2015, Graham 2005aGraham 2005) at the middle and possibly elementary school level (Klemmer 2005Pigg 2006). School gardens are associated with higher test scores among fifth graders (Ray 2016), as well as increased science knowledge among elementary students (Wells 2015). More intensive garden interventions are associated with greater knowledge gains (Wells 2015).

Research suggests that establishing, integrating, and sustaining successful school gardens over time requires ongoing attention to the physical garden, student experience, school community, as well as dedicated resources and support (Burt 2017).  

School gardens appear to be more prevalent in urban districts than rural ones, and in the western US than in other regions. School gardens are less prevalent in schools with high proportions of students from families with lower incomes than schools in more affluent areas. School gardens are also more common in schools with farm to school programs (Turner 2016). 

State laws that support school gardens are associated with the use of garden produce in school nutrition programs (Turner 2017). 

Implementation

United States

Most states have schools with school gardens (NASBE-Competitive foodsKidsgardening.org). State departments of education, departments of agriculture, and university extension programs can actively encourage school gardening; examples include California (CDE-Gardens), Florida (FL DACS-Gardens), South Carolina (SCDA-SC F2I), and Louisiana (LSU-Ag Center). 

Community organizations such as DC Greens (DC Greens-School support) and Gorge Grown Food Network (GGFN-SGN) also support the efforts of schools and teachers to maximize school gardens, integrate food education into standard curricula, and develop school garden programming.

Surveys suggest that approximately 30% of elementary schools have school gardens as of 2014 (Turner 2016).

Wisconsin

The Wisconsin Department of Health Services provides support to school gardens through its “Got Dirt?" gardening initiative (WI DHS-Got Dirt) and the Wisconsin School Garden Initiative is increasing the number of sustainable gardens at schools, after-school sites, and childcare centers across Wisconsin (WSWP-WSGI). Over 30 WI schools are listed in the Kidsgardening.org register (Kidsgardening.org).
