Course Details


Come join us for our biannual permaculture design course - the ninth time we have taught this course - here at Hundred Fruit Farm. The permaculture design course, or PDC, is an intensive 72-hour internationally recognized permaculture certification. It's designed to give participants the inspiration and knowledge they need to make a positive change in the world, needed now more than ever. It will give you the skills necessary to design your home/yard/landscape into an ecologically-resilient edible system, and for some, it could be the first stepping stone to a permaculture career in design, education, consulting, or regenerative farming.


This course will be offered as a weekend course designed for local residents who don't have time to take an intensive (and expensive) two-week PDC. This course will be mostly classroom-based but will also include hands-on components. It will go through the basics of permaculture design relating to different climates, energy, natural building, the global climate, social systems, and more. The course curriculum includes:

  • how permaculture started and what it means

  • the ethics of permaculture and how it informs what we do in designs

  • permaculture design principles and how to apply them

  • design process: a detailed run-though of the design process used in permaculture, including methods of design and how to apply design strategies

  • how to mimic natural systems to create better design

  • climatic factors and strategies, covering all major climates

  • trees, forests, and forest gardening

  • no-spray knowledge: learn which fruit trees and berries grow well here and which do not; how to grow a wide range of easy to care for and disease-resistant fruits

  • water: managing runoff, conserving, collecting, reusing water in your design

  • soil: learn the basics of soil chemistry and biology and how to work with the soil food web to build new soils and repair degraded land

  • earthworks: learn how to shape the land to prevent or remediate drainage problems and maximize the benefits of your natural resources

  • ecological sanitation systems: turning waste into a valuable resource

  • aquaculture and aquaponics

  • animal systems: the importance of animals in food systems and the symbiotic relationship between plants and animals; how to design silvopasture systems and other regenerative integrated animal systems

  • natural building: how to build beautiful, inexpensive, resilient structures using available natural resources

  • appropriate technology: home-scale biogas, solar cookers, rocket stoves, etc.

  • alternative systems: alternative economic systems, food sovereignty, community living

  • permaculture as a tool for sustainable development: using permaculture where it's needed most in underdeveloped countries lacking basic sanitation and infrastructure

The final part of the course will focus on co-creating a viable real-world design for a site that could include gardens, fruit trees, greywater systems, rainwater catchment, food forests, natural building projects, and more. Participants will have the opportunity to have their site designed by other students in the class.


Course Format


Classes will be held in person on Saturday and Sunday on alternating weekends from 9 am to 5 pm over a 12 week period at Hundred Fruit Farm in Buckingham, PA, for a total of six weekends with classes: Sep 2-3, Sep 16-17, Sep 30 - Oct 1, Oct 14-15, Oct 28-29, and Nov 11-12. Students are expected to eat breakfast and dinner before and after class. Lunches will be potluck style with each person bringing a dish and sharing with the group. Hundred Fruit Farm will also provide provide tea, coffee, and occasionally snacks for breaks. At the end of the course, we will have a End of Class Party at the farm in which all current and former PDC students will be welcome to attend!


The cost of the course is $900 per person. Most PDCs cost anywhere from $1000 to $2500. Why is ours cheaper? By designing this course for commuters and local residents, we don't need to factor in the cost of housing and meals into the course, which keeps costs down significantly.


Low on funds but have lots of spare time on your hands? We also offer PDC tuition reimbursement for anyone who completes an internship program with us! 

Who is this course for? 

This course is aimed at anyone who wants to live a more sustainable or regenerative lifestyle, bring more meaning into their lives, build a stronger community, and/or work towards an ecologically responsible future. This course is also ideal for backyard gardeners, homeowners, landscapers and landscape designers, teachers/educators, farmers, community organizers, nonprofit workers, orchardists, horticulturalists, students, etc. The curriculum of a PDC is designed to be introductory in nature, so there are no prerequisites needed to take it.

Course Instructors

Adam will be the primary instructor and facilitator for the course, but several other experienced and professional permaculturists in the region will join the course as guest teachers for certain sessions. Guest instructors for previous courses have included Lindsay Napolitano and Johann Rinkens from Fields Without Fences; Dale Hendricks from Green Light Plants; Ben Weiss from Susquehanna Sustainable Enterprises; Robyn Mello from Edenspore; JC Hogan from Earthen Arts Ecological Design; Gregory Crawford from Surplus Permaculture; Michael Green; Sara Wuerstle from Guilda Permaculture; and Jason Gerhardt from the Permaculture Institute. Guest teacher pictures and bios will be added below as they are confirmed for the course. Usually there are about four or five other guest teachers in every course.

Adam Dusen

Adam is the main teacher and facilitator for the course, and divides his time between running Hundred Fruit Farm and creating regenerative and productive permaculture designs for clients throughout the mid-Atlantic. Adam has previously helped manage the Panya Project, a permaculture educator center in Thailand, and served as a farm manager and permaculture teacher at The Island School in The Bahamas. Adam has a passion for regenerative farming that combines integrated animal systems with fruit and nut diversity. When not farming, designing, or teaching, Adam will usually be out paddling on a river somewhere in a canoe or kayak. Check out Adam's full bio here.

Michael Green

Recently relocating back to the Philly region that he calls home, Michael spends his weekdays continuing his work as an educator in the alternative school setting where he sees much potential to redesign the classroom, through a permaculture lense, to allow greater opportunities for experiential, community based learning. Michael is especially focused on social permaculture and is currently working to strengthen and develop networks of communities that will continue to enhance our interdependence and resiliency by creating spaces for connecting with and learning from one another.


Dale Hendricks

Dale is a nurseryman, avid fruit explorer, biochar expert, and all-around jokester who's been growing and propagating plants professionally since 1975. He has been honored with the American Horticulture Society’s Individual Commercial award and the Perennial Plant Association’s Young Professional award. He has taught plant propagation at Longwood Gardens and lectures widely across the region. Dale is the operator and owner at Green Light Plants, under which he consults on sustainable and fecund landscapes and grows native, woodland, and permaculture plants renewably, organically and joyfully. Dale lives with his family, gardens and makes biochar whenever he can in Landenberg, PA.

A Bucks County native and resident who has worked internationally with leading permaculture practitioners, including facilitating more than two dozen PDC courses and trainings worldwide. She spent 5 years as the lead designer for a Bay Area Permaculture design, installation and maintenance firm, where she fine-tuned her skills in flood, drought and wildfire mitigation. Most recently, she co-founded GUILDA Permaculture with Eunice Neves to tackle broader global challenges through collaboration with policy-makers, community groups and businesses.

What happens if I miss a class or a weekend? Can I still receive my certificate?

This is one of the questions we get asked the most. We understand that everyone lives busy lives and there are going to be times when you will have to miss a day or weekend. Any relevant notes or presentations from each class are uploaded into a google drive folder that everyone from the course will have access to. To receive your certificate, you must attend at least 75% of the sessions and take part in the final design projects and presentations. If a student is unable to be part of the final design presentations, we will work with that student to schedule an online design presentation via zoom. Anyone who drops out or fails to complete the course can re-take any future PDC course with us again at 50% cost.


Do I have to commute?

This course is designed for people who live close enough that they can travel to and from class each day. That being said, every year we have students attending the course who live 2+ hours away. Some people who live a little further may find that it makes more sense for them to stay somewhere locally Friday and Saturday nights to cut down on travel time. We are happy to suggest nearby accommodation for students who wish to do this (although truthfully, the options around this area are fairly limited), but we do not yet have the facilities to host students ourselves on the farm. 

How far is the farm from Philadelphia and NYC?

Depending on where you're coming from in Philly, our farm is about 50 minutes to 1 hour away. We are about 2 hours away from NYC. Most people who take the course are from Philadelphia, Philly suburbs, and Central NJ, but we have had students coming from as far as NYC, Delaware, and Central PA.

What ages are the students? Am I too old or too young to attend?

Our students are all adults (18+) of all ages. We have had students as young as 19 and students well in their 70s. It's a very welcoming environment for people of all ages.

I am a vegan and I'm not sure if I should take this course. Is this a vegan-friendly course?

We want to be very clear that we do raise some animals for meat on this farm, always on pasture and as ethically and humanely as possible. Animals are a major component of both indigenous cultures and permaculture systems around the world, and when done properly, animal systems enhance and support the agroecosystem in countless ways. So we want any vegan who takes the course to be fully aware that this is the case for us. That being said, we welcome vegans and vegetarians and people of all dietary choices and always maintain a very respectful atmosphere in the course for different dietary choices. Although we have had some people decide not to take our course because it conflicted with their vegan ethics, every vegan who has taken our course has had a great experience.

Do black lives matter?

You're goddamn right they do! We support Black Lives Matter. For the most part we keep discussions of politics outside the realm of this course except where it pertains to permaculture directly. But we believe there is nothing political about saying that black lives matter, because they do.

Is this a safe space for LGBTQ people?

Absolutely! We welcome all genders and sexual orientations and will not tolerate hate, racism, sexism, or discrimination of any kind at our farm or in the course. 

How do I register?

To register, you will need to pay a 20% deposit ($180) to secure your place in the course. To register and to pay this deposit, email us and let us know you want to register, and we will give you instructions for how to pay the deposit. The remainder of the course tuition is paid in person when the course begins. Please also feel free to contact us if you have any questions about the course. Deposits are non-refundable unless you cancel your registration no less than 60 days before the course begins, or unless the course is cancelled by us, in which case you will be fully refunded for any deposits made. 

Please note that this course usually fills very quickly every year, sometimes in only a few weeks once we make the course live. So don't delay if you are thinking of signing up, because the course may be full by the time you get around the registering later.
