Our six-acre food forest sits quietly within the old Hawaiian rainforest, a place where the hum of jungle life surrounds you and the unmistakable call of coqui frogs fills the night air. This is no polished resort but a working, off-grid farm where fruit trees reach for dappled sunlight and the rhythms of nature guide our days. Here, we've spent decades learning how to live with the land instead of against it, tending to a diverse food forest rooted in permaculture principles and hands-on experience. This farm honors Josanna's memory by sharing its abundance with the community and teaching those who come after us how to care for this land. What follows is a grounded look at how we manage sustainable agriculture in this unique Hawaiian setting - a glimpse into the practical, sometimes messy, always rewarding work of stewarding a food forest that feeds both body and spirit.

Principles Of Permaculture In Our Tropical Food Forest

When we talk about permaculture here, we mean learning the rhythm of this wet, wild jungle and arranging the food forest to follow it. The goal is simple: let the land do more of the work, and stop fighting what wants to grow.

The first principle we lean on is working with layers. In the canopy we have taller trees catching full sun and wind. Under them, shorter fruit trees sit in dappled light. Beneath those come shrubs, then herbs, then ground covers hugging the soil. Vines run up trunks and trellises instead of taking up their own space. Each height has a job: shade, windbreak, mulch, food, or habitat.

That stacked structure copies the native forest. Sun hits many levels, not just the top. Fallen leaves from the canopy feed the soil for everything below. Ground covers keep roots cool and slow the hard rains. This is how we think about sustainable agriculture in Hawaii: less bare soil, more living layers.

We also pay attention to patterns rather than single plants. Instead of one row of papaya, we plant small mixed clumps: a couple of trees, a nitrogen-fixing shrub, a pollinator-friendly flower patch, and a low plant to shield the soil. If one crop struggles, something else in the group still thrives. That mix gives us hawaiian food forest crop diversity without needing huge fields.

This is where agroforestry comes in. We treat trees, shrubs, vines, and ground covers as one community. Deep-rooted trees pull minerals up. Shrubs and vines use the filtered light and feed bees. Ground covers and leaf litter protect the soil and become future compost. Animals and insects move through all this, spreading seed and keeping some pests in check.

Permaculture shapes how we think about everything that follows: which crops we add, how we rotate harvest areas, where we drop prunings, and how we build compost. The food forest stays resilient because each layer supports the others, from the tallest canopy tree down to the thin skin of soil under our bare feet. 

Crop Diversity And Its Role In Farm Resilience

Once the layers are in place, the next question is simple: what fills them? For us, resilience starts with planting many kinds of food, not betting on just one or two favorites.

Up in the high canopy, we keep taller trees that handle wind and sun. Breadfruit, mango, and taller avocado form a loose roof. They slow the trade winds, drop leaf litter, and hold moisture in the understory. Scattered among them are nitrogen-fixing trees that feed hawaiian soil health composting efforts with constant leaf fall and prunings.

In the middle layer grow smaller fruit trees and nuts. Bananas, papayas, citrus, cacao, and dwarf coconuts sit in the broken light. This is where most people's eyes go first, because this is where the bulk of the daily harvest comes from. Between them we tuck in kukui, ʻulu keiki, and other culturally important trees that remind us this is old Hawaii, not a neat orchard grid.

Shrub level holds coffee, hibiscus, chili peppers, and medicinal plants like mamaki and turmeric. These fill gaps, draw in pollinators, and give us leaves, flowers, and roots for the kitchen and tea table. Their roots knit the soil between tree trunks so hard rain does less damage.

On the ground we use sweet potato, comfrey, ti, lemongrass, and perennial greens instead of bare dirt. They shade the soil, soften heavy showers, and feed our compost piles when we chop and drop. Vines like lilikoi and edible gourds climb up existing trunks instead of taking new space, tying the whole tropical food forest design together.

This mix matters for more than taste. Pests tend to specialize; when every few steps the plant changes, their spread slows. Some strong-scented herbs and flowers confuse insects. Tough border plants blunt wind and salt, while deep-rooted trees pull minerals up for shallow-rooted vegetables. When a wet season knocks back one crop, another peaks, so we still have food for the table and the community.

That steady, shifting patchwork is what Josanna wanted here: a place where bananas, ʻulu, weeds, and medicine all share the same space, and where WWOOF students and visitors see how real crop diversity in a hawaiian food forest feels underfoot and overhead. Managing it means pruning more than plowing, observing more than forcing, and trusting that a mixed forest will carry us through strange weather and normal seasons alike. 

Daily Soil Care And Composting Practices

All those trees and shrubs only thrive if the thin skin of soil under them stays alive. Our volcanic ground starts as sharp rock and ash. On its own it holds little organic matter, so our main task each day is to keep feeding it.

Composting is where most of that feeding begins. We sort materials into rough layers: green, wet matter for nitrogen, brown, dry matter for carbon, and a bit of finished compost to seed microbes.

• Greens: banana leaves, papaya stems, kitchen scraps, coffee grounds, and fresh prunings from the food forest.
• Browns: dry leaves, shredded cardboard, old mulch, coconut fiber, and stalks that have started to toughen.

We build piles directly on the ground so fungi, worms, and centipedes can move in from below. Each layer gets watered just enough to feel like a wrung-out sponge. In our wet climate, too much water turns a pile sour fast, so we use loose materials and avoid packing anything tight.

Turning the piles is steady, simple work. Every week or so we flip the outer material toward the center, check moisture by hand, and add more browns if things smell sharp. Steam on a cool morning tells us microbes are busy. When the pile cools, darkens, and smells like forest floor instead of food, we spread it.

Finished compost rarely goes on in a thick mat. We tuck it into planting holes for new trees, dust it around heavy feeders like bananas, or blend a thin layer under fresh mulch. That way the microbes stay shaded and do not dry out.

Compost is only one part of how we protect this ground. We keep soil covered almost year-round. Chopped prunings, palm fronds, and fallen leaves become mulch around trunks and paths. Living covers like sweet potato and perennial peanuts weave between trees, soften heavy rain, and slow erosion.

Where we need to rest a bed, we use quick cover crops instead of leaving bare dirt. They throw shade on the surface, mine nutrients with their roots, and then drop back into the cycle when we cut them down and lay them in place. We disturb the soil as little as possible. Instead of tilling, we use hand tools to open just enough space for roots, leaving fungal networks and worm tunnels intact.

These habits add up over years. Compost, mulch, and minimal disturbance build a dark, crumbly layer where there used to be pale cinder. Trees root deeper, bananas lean less in storms, and the food forest needs fewer outside inputs. When we run composting workshops or walk visitors past the piles, what we show is not a complicated system, just consistent attention. Scraps go to the heap, prunings drop where they fall, and the soil slowly gains the strength to feed us back. 

Sustainability In Daily Farm Life And Operations

Sustainability here is not a slogan; it is how we get through the week without burning ourselves or the land out. Every choice, from when we flip a breaker to where we dump a bucket of rinse water, has to fit the limits of this off-grid, jungle home.

Our power starts with the sun. A small solar system runs lights, pumps, fridges, and enough outlets for tools and a bit of work time. We plan tasks around daylight and battery levels. Heavy draws like freezers, power tools, and laundry wait for clear mornings when the panels are full. When clouds stack up, we fall back on hand tools, gas for only what matters, and early nights with headlamps and candles. That rhythm keeps our footprint and our power bills low, but it also keeps us honest about what we actually need.

Water gets the same attention. We collect rain and move it slowly through the farm. Catchment tanks, gutters, and simple gravity lines feed sink taps, outdoor showers, and irrigation. Hoses reach priority areas only; the rest of the food forest leans on mulch, shade, and deep roots. We schedule big hand-watering for seed beds and new transplants early in the morning so less evaporates. Dishwater from the outdoor sinks heads to bananas or vetiver clumps, never to waste ground. When a dry spell hits, everyone feels it: shorter showers, fewer laundry loads, and more time mulching to hold what little moisture we have.

Waste has to earn its way here. Green matter returns to soil care for organic farming through compost, mulch, or direct chop-and-drop in the paths. Tree trimmings become bed edges or rough trellises before they finally rot down. The pig pen, when we run pigs, sits where their rooting and manure can repair tired ground instead of wrecking a fresh corner. They clean up breadfruit, coconuts, and kitchen culls, then send that fertility back as manure we compost carefully before spreading.

What we cannot compost, we sort. Recyclables stack in a covered corner, and we keep a small bin for actual trash. After enough WWOOF seasons, we know which snacks, packaging, and gear generate the most waste, so we steer farm shopping toward bulk, reusable, and simple materials. It is not perfect, but each adjustment trims the pile that leaves the land.

Living this close to the forest means we answer to it daily. Lights stay low at night for insects and birds. We leave corridors of wild growth between planted zones so native species still have cover. Traps and hand-picking come before any stronger pest control, and we accept that some fruit goes to birds, rats, and insects as part of the deal. Old Hawaii organic farming, at least the way we understand it, respects that the jungle was here before us and will be here after us.

Teaching keeps these habits alive. WWOOF volunteers do not just hear about tropical permaculture living in Hawaii; they lug the hoses, clean the solar panels, and stir the compost. Morning rounds include checking water levels, turning piles, feeding animals, and walking the trees for signs of stress. Garden parties fold work into community: harvest in the afternoon, clean and cook together at dusk, then eat under the trees while we talk through what went right or wrong that week.

Farm-to-table meals carry the same thread. We walk guests through the beds, pick what we will cook, and explain which parts of the meal came from long-term soil building, careful water use, or animal integration. The food is simple - ʻulu, greens, herbs, eggs, fruit - but every plate is proof that slow, steady habits still feed people. Keeping Josanna's farm thriving means holding that line every day: accept the mud, the mold, and the breakdowns, keep learning from the land, and share whatever we figure out with the next set of hands who arrive at the gate. 

The Role Of Education And Community In Our Sustainable Farm

Education here does not live in a classroom; it lives in muddy boots, stained cutting boards, and questions asked while hauling mulch. For twenty years we have hosted WWOOF volunteers who learn by doing: pruning bananas, turning compost, planting ʻulu keiki, and cooking what they picked that morning. The food forest becomes a moving textbook on agroforestry in Hawaii, natural farming methods, and what it takes to keep soil and people fed over time.

WWOOF days usually start with a simple walk-through. We point out what changed overnight, which trees are flowering, where pests are building, and how last week's chop-and-drop already softened the ground. That slow, daily tracking teaches pattern recognition more than any manual. Volunteers see how one decision with a machete or hose ripples through the rest of the system.

Guests and neighbors step into the same living classroom, just in shorter visits. Farm tours wind through the orchards, compost areas, and kitchen spaces. We explain how layers, water use, and soil care connect, but we also pass around leaves to smell, fruit to taste, and mulch to crumble between fingers. Composting sessions stay hands-on: sorting greens and browns, checking moisture, and watching how fast tropical piles heat and cool in this humid climate.

Farm-to-table meals tie everything back to the plate. We walk the beds, gather what is ready, then cook and eat together while talking through each ingredient's path from planting to harvest. Those conversations often reach beyond the fence line: how to adapt these ideas back home, how Hawaiian jungle organic farm practices differ from mainland gardening, how to share abundance without stripping the land.

Community, for us, means more than visitors passing through. It includes long-time neighbors who trade seedlings, workers who have watched trees mature, and returning WWOOFers who see how their earlier efforts grew into shade and fruit. Sharing what we know, and admitting what we are still figuring out, keeps Josanna's vision active instead of frozen in time. Knowledge moves through this place the same way nutrients do: passed along, broken down, reshaped, and then taken up by whoever shows up ready to learn and lend a hand.

Our food forest is more than just a patch of land; it's a living example of old Hawaii's jungle lifestyle intertwined with thoughtful, organic farming. Here, permaculture principles guide us as we nurture diverse crops, care for the soil, and live sustainably every day. This steady, respectful approach honors Josanna's memory and keeps the farm thriving for the community and the generations to come. Whether you're curious about how the layers of trees and plants work together or want to see composting and water conservation in action, there's something to learn and appreciate at every turn. We invite travelers and farm enthusiasts alike to visit Hawaiian Retreat, take a farm tour, stay in one of our rustic cottages, or share a farm-to-table meal with us. It's a chance to experience firsthand the rhythms and rewards of working with the land in this special corner of Hawaii.
