Building Worm Paradise in Hawaii

Being raised on a Wisconsin farm may have given me rather high expectations for soil. Our humble 40 acre farm had deep, rich, black soil that you could sink your arm into, well past your elbow. That was considered “below average soil,” and that is where my false soil illusions began.

My brother and I would hunt night crawlers and all kinds of earthworms for Summer trout fishing. It was rarely much of a challenge to fill a bucket in a few minutes. The biggest challenge was to dig without severing the multitudes of them that squirmed below our shovels. We often abandoned the tools so to dig with our hands. We also wanted our worms to be happy and content in their last hours before they became trout bait. So sever we would not.

Fast forward over three decades and several thousand miles and land me in the Hawaiian islands where you would again find me digging in the dirt in search for worms. The result was quite different, because day after day, I found none. Not a single worm. This was a discouraging discovery that I needed to resolve, because if there were no worms, there would be no farm.

Industrial agriculture, wind erosion, lack of cover crops, multi year drought, years of nutrient depleting sun, and lack of organic materials, are things to consider when beginning a transition plan for a parcel. Though this area was prized for being some of the richest soil in Hawaii, that estimate took into account only soil type, and left nothing to be said for soil treatment.

The summary was easy: there was nothing to temp a worm to take up residence, and every other action on the farm was contingent upon this cornerstone of soil health.

The solution was equally clear: create a worm paradise.

If key players like worms were missing, that was a good indicator that other members of the soil building chain, like soil microbes, were also in short supply. I decided to focus my attention on the actions of one person, and develop a farm plan based around a worm’s favorite location: the compost heap. Creating a farm that was comprised of an organized pattern of composting heaps that would be piled on top of existing soil. The squash crop to be would be planted directly into the decomposing heaps, benefitting by the heavy food source available. The worms would be able to pull nutrients from this moisture and food rich pile, and bring the nutrients deep into the depleted soil.

No-till was an easy choice for methods, because a decade long drought and wind erosion had left little to till. No-till gardening techniques were expanded to a 1/4 acre scale. Between garden and farm in proportion and methodology, this framework would conserve moisture, encourage microbes, worms, and stifle weeds.

Cardboard created a zero waste solution, along with growing blocks reclaimed from the local hydroponics farm. Together, the cardboard, and both basalt and coconut coir growing blocks would create a moisture holding, shady mulch where worms could hide and soil would form. As pumpkins were harvested, some would be chopped into chunks and buried face down in the mulch. This created “worm buffets” that were also cool hiding places where worms could gorge and reproduce.

The image says it all.  The additions have changed the soil dramatically.

Now a year later, the soil is several inches deep of sweet smelling soil. Just like the days of my childhood, I often dig with my hands so not to risk severing any of the welcome guests that will not become trout bait. An “intensive soil care” initiative was the first move for the farm, and the efforts have surprised even the most hardened of soil scientists. Now reconditioned into a healthy soil system, EM-1, homemade fish emulsion, and coffee grounds are the additions made to the area.

Vines now tumble and interlock with each other, birds, bees, and butterflies circle overhead. Mushrooms show themselves and again disappear into the cycle. The purple worms surface and dip through the paradise that was both created for them, and one that they helped to create. Several tons of food has been gathered from a small, once dusty parcel, giving hope to one more farmer who has spent their first year farming new soil.

Fish Composting Beds Opened!

Remember this? Well….I am very pleased to report that it is now this!

Compost

I used EM-1 to add even more rich microbes to the heathy new compost and replace any that may have gotten burned out when the fish composting really heated things up. The fish composting was a success! (yeah! Thank you to Redwater Cafe and their continued donation of green waste and fish bits, Merriman’s for cardboard, and Starbucks for the donation of coffee grounds to help me build the soil!) The compost is a bit chunky due to my using a lot of sticks, but after a little bit of sifting out large pieces, the new compost was ready to be added to one of the beds. This will give a Spring makeover to a well used bed.

Simple and straight forward…fine pieces of fish scrap make a rich odor free fish emulsion when combined with unrefined sugar (or a mix of molasses and sawdust from untreated wood) in thin layers.  Top off with sugar in a thick layer, leave plenty of airspace at the top, and use a cotton tee shirt to allow it to breathe.  Periodically, you will continue to top dress with more sugar as needed.  The perfect rainy day gift making idea.  Who wouldn’t love to be suprized with this zero waste treat for their garden.

Leave in a shaded corner (garage or barn is good) where you can check on it.  It will take a few months to fully breakdown.  The rich dark syrup will then be used as approx one shot glass to 5 gal of water.  It will revive plants and help your farm and gardens grow.

 

For the Love of Baskets

Bringing a bit style to my deliveries are the baskets the I use. I have tried my best to make a sustainable, stylish solution to delivering to the chefs of Hawaii. They have loved the vintage style that both the car and the baskets add to their day. I have even been asked to leave my ol’ little car out in front of Merriman’s restaurant at their 25th anniversary party. Both “Pixie”the car and the delivery basket brimming with squash are featured on this month’s special 4-course squash menu at the Hapuna Beach Prince Hotel.

Both examples prove that an inexpensive, stylish, zero-waste solution comes in ahead of mainstream produce marketing. Rethink your marketing and delivery system and you may win by creating a big cost savings for your farm, and a meaningful connection with your customers. Do it your own way…guerilla style.

Fruit Fly Warfare

It isn’t my nature, but I have been slinking around like a true guerilla with my sites on the fruit fly population.  I wrote a 4 page essay on my findings, that I will spare you for now.  I will unleash it on my readers soon enough.  As some of you bundle up, and pour through your seed catalogs in hopes of Spring, perhaps dreaming about lands where there there is no true Winter, let me remind you, here in Hawaii we have the same brutal Agricultural pests as the Congo.  I wish I were joking.  One soon learns why 90% of our veggies are shipped in from Fruit fly free localities.  Here in Hawaii we are in the heart of yet another fruit fly “bloom” (they can have 8 to 9 cycles within the Calendar year. ) I refuse to be defeated.  Who knows, maybe outsmarting tropical pests will be my legacy.  It isn’t glamorous, but it is true.  OK back to the war…

Three waves of determined effort are necessary, and well, a continuous parts of your growing practice here in Alohaland.

Clean crop practice: I bag the stung squash in reused metallic coffee bags that my Starbuck’s Grounds for your Garden come in.  I then place them in the sun for a couple hours before they are dropped into a sealed bucket where they will die and decompose in the weeks again.

Lures:  The men are targeted and lured by the use of the right scent for the right fly ( sorry guys.)  Though Oriental Fruit fly does not attack squash, they are on the property in large numbers, so I am taking them out for the benefit of someone’s crops.  They may be feeding on a neighbor farm. The mean, but gorgeous Melon fly is my leopard spotted enemy.  Cure lure is their bait.  See reused cup trap image in prior post for the general idea.  Homemade traps have cleared hundreds of males from the two varieties, with the bulk being Oriental Fruit Fly.

Bag…no double bag ’em:  I have used my fledgling Blue Hubbard as a case study plant, trying out all kinds of strategies.  So far, my vote is for a quick, but meaningful hand pollination followed by a parafin wax baggie, topped with a brown paper lunch bag.  Driven by scent, this seems to be a good solution so far.

Fish composting and fish emulsion

This week feels like two. It is a hot week here in Hawaii.  What better time to be carting about my body weight in fish heads?  Yes, you heard me.  Alright, so it isn’t an ideal time to be working with raw fish, but opportunity knocked, and I answered. The theme of the week is to make use of even more restaurant waste.  What better place to make the most of the discarded fish bits from our beloved Ahi and Mahi Mahi?  The Chefs have set me up with enough fish heads to enrich the new farm addition. I am getting my composting game in overdrive with the gloves pulled up high for this messy week….but I am ready and grateful for the challenge. And it should also be noted that I say a small prayer of gratitude for each fish that is added to the soil building project.

Fish composting and fish elulsion making are on the adjenda.

Organic no-till, sheet mulching, lasagna gardening

It takes a lot of time up front in the collection of mulch materials, but the big gain is that your squash plants can feed for months on the rich nutrients that you have made for them.  I plant when the bed is new.  That is not ideal, but it allows me to hit production faster.  Being in Hawaii, our composting beds age quicker than in cooler climates.  By the time the pants are two to three months old, the beds are beginning to break in…by six months (squash grow year round here if you work hard) the beds are getting rich and crumbly.

Sometime in my lifetime, many farmers forgot how to build soil

For hundreds of years, farmers built the soil as a foundation for the food that fed their families.  A foundation for their future. A built-in daily vitamin for themselves that would be harvested in the months ahead.  Then something happened when I was still measured in relation to my Gandpa’s knee.  There were better ways, they were told.  Better?  Faster, more….but really it was the point of diminishing returns.  More lackluster crops were produced in greater numbers.  A strong line was drawn. Agricultural crops were now treated very differently from vegetable gardens.  Farmers seemed to hang on to the build the soil method in the vegetable patch that fed their family, and in times of need, their neighbors.  Why was that?  Was it because that was the domain of the woman of the house?  She held onto these methods that are methods that organic farmers still use today.  Rotating, covering, mulching…So was it scale that was the issue?  Probably.  In the never-ending American push that bigger was better, we learned quite late that bigger was simply bigger. And the “better crop” was in the farmer’s own veggie patch.  

Can You Even Recognize It?

One quarter acre all filled out after 7 months of farming.  We can do it, everyone!  Every inch of soil…and it is now deep rich soil, was lovingly built with one woman (me,) one shovel, and a fair bit of focus.
