Project Lemon Tree

A hands-on learning program for school, home & community.

Grow a Better World Through Lemon Trees!

Why Lemons?

Of all cultivated plants, Lemon trees are the top sequesterer of CO2, (see citation). Lemons are also a high value agricultural crop, used in cuisine world-wide and have active ingredients useful for cleaning and fragrance products. For education, Lemon tree planting offers experiences in soil science, agriculture practices, design and construction, culinary arts, innovation and entrepreneurship. Lemon Trees are also school-safe, drought tolerant and low maintenance. For FAQs and more, see About »

Leveraging Lemons to Learn

PLT empowers students to design and build their own outdoor classroom. Options include planting lemon trees in pots, planting in the ground and building support structures like trellises and pergolas. See Video »

PLT Curriculum features 16 modular activities that empower teachers to customize syllabi to fit available time, interests and resources. Our Teacher’s Guide includes a quick-start checklist, student handouts, student surveys, Care Plan and CCSS Alignments. Student Journals include team-building, Project Journaling, instructions, tips and examples. See Curriculum »

Student Perspective

I feel so lucky to have been part of the Project Lemon Tree (PLT) at Jefferson Elementary School and Kalani High School. It was truly inspiring to witness a community brought together to positively transform a torched playground to a beautiful pergola…

I gained many valuable critical thinking, presentational, and management skills… I learned how to build a scale model… how a trellis should be constructed and how to create a presentation to share the project. This project also taught me how to facilitate the process of building, initiate weekly reports and collaborate with others.

After hearing how lemon trees reduce carbon dioxide in our atmosphere and that gardening spaces will teach children about sustainability, my motivation to engage in serving our community, environment, and education system grew.

Teacher Perspective

The curriculum was based on “Why Lemon Trees?” Every day we talked about how we’re going to take care of the lemon trees, how we’re going to use the lemons in the future and how we’re going to connect with our community. This program gets them ready for the real world.
