One of our goals for simple sustainability, is a Fruit tree in every yard, even on your apartment lanai. For years Mark and Candy Suiso and their extensive extended ohana, participated in the epic Fruit sharing event known as Mangoes at the Moana.
This was Mark’s simple message for all the ten years we staged this educational and fun, Ono for Mango fruit, local fun foodie event. Remember when every yard had at least one fruit tree, lots of vegetables, all kinds of things for the family to eat and to share?
Share with ohana, gifts for the neighbors, take a generous bag to work, etc.
Kupuna Pua Mendonca of Hawaii island shared some simple wisdom with me at an Aquaponics training conference in Hilo: survival trees to grow are avocado, niu or coconut, and `ulu or breadfruit. Those healthy fats and oils will get you through times of hardship and scarcity.
You’ve heard the scary news that we have one week of food on grocery shelves in Hawaii. Should we get cut off from imports, its handy to have some degree of self-sufficiency.
So, lets grow some survivor supplies in our gardens. I was visiting my great gardener neighbor Joan Takamori and admiring her plush and fruitful garden. She always has something to share and we learn from each other as we talk garden story.
Takamori asked me about a macadamia nut cracker. She had an abundance of macadamias from her mother’s garden.
I laughed, recounting our nutcracker as kids. It was a big pohaku in the dry stack rock wall, that was flat on top and had an almost perfectly sized mac nut puka. We would set in a nut, and hit it “just right” with a small sledge hammer. Sometimes it cracked open perfect, sometimes we smashed too hard and sometime the nut went flying!
This is how I learned (without knowing it) about scarification, a technique to help tough thick shelled seed to germinate and grow. The nuts we nicked that flew down the side sloping yard, were able to grow into seedlings.
Once when we had a cousin swap, I took a big paper bag of macadamia nuts to my Aunty Ruth in California (what a hostess gift, such an elegant bountiful paper bag!)
I told them how we cracked mac nuts at home. But no! Californians have a better plan! And my Uncle Merle was an Engineer. He had a vise in the garage. It was a big thrill for my cousins’ many friends in their neighborhood, to come over and everyone got a turn cracking a nut. (Sort of like Tom Sawyer getting all his pals to paint the fence, I later thought, with a laugh!) Akamai uncle Merle!
My Aunty then roasted the nuts in the oven and covered them with chocolate. Back home we generally just ate them raw.
I told Joan all of this and how my friend Nyna Weisser had researched nut crackers online and found a great one. Not cheap but perfect cracking. Nyna would hand us nuts and the cracker at a party. Fun for all the friends!
Joan Takamori and I also spoke about how macadamia nuts are another tree that more of us should propagate and grow.
They are a pretty tree with deep green ruffly leaves and very pretty and fragrant flower stalks. If you look closely at the flowers you will see that they look like miniatures of one of our favorite modern-day Florist ornamentals: Proteas.
Mac nuts are in the Proteaceae plant family and they are native to Australia.
I asked Joan about where her folks got their macadamia tree. She didn’t remember it being in the yard forever, and She has a theory.
‘My dad did bonsai my mom didn’t drive; she knew how to catch bus everywhere. I think she stole that tree from him and set it free in the yard’ says Takamori.
We never had it growing up. I think mom planted it, maybe about 10-15 years ago. She wanted to see it flower and fruit, although it would’ve made a kewl bonsai. Its now a very fruitful tree. I want to grow more of them, so I’ve been collecting seedlings, from under her tree to grow and share and plant in my current garden.
Mac nuts need to be scarified to germinate. The thick hard shell is nicked or filed down a bit so water can penetrate and activate the embryo of the seed to grow. Plant them in pots with quality potting mix, and water daily, until they get big enough to go into the ground.
You can also buy them already growing. Ask for them at your favorite garden shop. Or for even more fun, call ahead and visit a fruit tree specialty nursery. Buy some mac nut trees to grow and maybe another fruit tree for a friend or neighbor to grow.
