We had such a weird windstorm with those super strong and gusty west winds! So different then normal.
Up in our valley we lost power twice to the wind and HECO did not restore power until 9:30 p.m. on Wednesday 3/8/2023.
Mangoes and avocados were full of blossoms, Honohono orchids were in bud and some in bloom.
My Portuguese Madeira roses, and native Hawaiian gardenia Na`u have been blooming well, loving the cool and rainy winter were are finally having.
As I clean up the storm debris, (Mahalo for nature’s Arboriculture) including blown down dead twigs and branches, and lots of leaves, some I notice are from my mauka neighbors.
One of the tenets of true Horticulture is to OBSERVE nature and plants, to track the moon, winds, rain and other weather phenomena as see how the plants respond.
I am still reflecting on how the plants would respond.
What do you see? How are your plants after the winds?
Did you have any big tree failures? Or just small or dead branches?
The leaves are whipped on my gingers, Surinam cherries, mulberries, and ohia shed a few flowering branches. A young popolo plant got totally blasted on one side, it was just coming into fruit.
So, we shall see!
Honohono orchids had been in full glorious fragrant bloom as they budded and bloomed early this year. Originally I thought the orchids stood the wind storm but after a few days those in the main wind tunnel area of my garden wilted and withered prematurely.
Went to a neighborhood watch potluck pa`ina and a nice lady, Lokelani, that I always say hi to on my walks was there, with a gorgeous papale lauhala. She admired my honohono and said she caught a whiff of fragrance, from way across the yard, and she looked for the source of this favorite old time Hawaii fragrance, and from where? My hair!
Since she admired the orchids, I had to give them to her, along with maire ferns!
Now a couple weeks after the winds, I’m observing some of my favorite flowers and fruit trees in my garden and neighborhood:
• ‘Ohi’a lehua Blooming profusely, some dead wood branches and twigs broke in the winds
• Native White Hibiscus wind whipped leaves, a few blooms at the very top of the tree
• Tahitian mountain apples were blooming before, still many flowers and now small fruit.
• Gardenias surprise early blooms two on one stem, but no other apparent buds yet. (they usually bloom for me in May).
• Na`u, native Hawaiian Gardenia lots of flowers and buds (also triggered by abundant soft rains before the winds)
• Madeira roses Blooming profusely.
• Mangoes my Friend Dawn Shim from Makakilo brought me a gift of Haden mangoes, super early for this to fruit.
• Mulberries wind whipped leaves, lots of young fruit
• Pua Keni keni usually Bloom less in winter, BUT after the storm mine are full of Buds, flowers and lots of developing green “ball” fruit. I made some lei for a fundraiser, and plucked and cut off all the young fruit, to encourage more blooms from the tree
What are YOU observing, in your garden in your unique microclimate? I would love to hear back from my Gardening Readers …..
After three years of lockdown, we are finally, Happily, able to celebrate Arbor Day in Kapi`olani Park once again.
On Saturday November 19, 2022, we will gather with ScenicHawaii, Inc., Kapi`olani Park Preservation society, some Dedicated City tree workers and Arborists, Volunteers, and all of us who love and cherish trees and our Park.
We will be planting and ceremonially mulching four new trees courtesy of the Division of UrbanForestry led by Certified Arborist Brandon Au and DUF/ City and County of Honolulu Parks Department.
Citizen Forester Emily Perry will be representing our busy parks director Laura Thielen.
The trees are drought tolerant and are native to coastal subtropical forests of Australia.
The common name is FLAME Tree, or Illawarra Flame tree. Also called the lacebark tree.
One thing our mentor Paul Weissich, Director Emeritus of the Honolulu BotanicalGardens taught us, is to look beyond flowers when you view trees.
What does the bark look like? How is the truck shaped? What is the growth pattern? What kind of shade pattern does it adorn the ground with? What are the leaves like? Are they good for mulch and soil nurturing? For Keiki art projects?
As we Arborists say, “Touch trees”. Place your hand on the trunk and look UP! What do you see, in the Tree Canopy? I love doing this with keiki of all ages!
When we plant a tree, we are investing in, and finding out about the future. This small tree, grown from a tiny seed and planted today. What will it grow into in the Future?
We can read about the size and growth habits in a book, but how big will it really get here in Hawaii? Will it grow big and strong with proper nurturing and akami tree maintenance?
Will it withstand the abuse that trees sometimes take in public park spaces? Will most people be happy and respect the growing young trees? We sure hope so! Trees ensure a healthy, happy future for all of us.
Known in Scientific Latin as Brachychitonacerifolium, the Illawarra Flame trees are in the Sterculiaceae plant family.
We don’t have many of these trees in Hawaii. A few grow at Foster and Ho’omaluhia Botanical gardens. These were grown from seed by the Horticulturist and Plant propagators at Foster Botanical Garden.
They are particularly striking when in bloom,with bright red orange or scarlet flowers. The flowers look like a hanging red bell when viewed from the side. If you look directly at them, they look like stars.
The leaves are shaped like a kukui leaf, or a mainland maple tree leaf. This is what the species name acerifolium means. Acer is the Latin name for Maple, and folium as you might guess is referring to the foliage or leaves, maple shaped leaves.
The trees will grow up and into a pyramid shapewith a tall, greenish grey, smooth round shapedtrunk. In time they can grow up to about 100feet tall (30 – 35 meters). They are a popular street tree in Australia and around the subtropical world.
The seeds of Brachychiton species are edible. But like many plants in the sterculia family they have irritating hairs, which must be removed or carefully removed to get to the edible seeds. Native Australians ate them raw or roasted. They are nutritious, containing 18% protein and 25% fat with high levels of zinc and magnesium.
There are uses for this tree in its native Australia. Fiber is made from the bark and a kind of gum can be extracted. The wood is soft but dries hard. Shingles, among other things, are made from the wood. The roots of young trees are edible, but let’s not do this in our park!
A related tree, Brachychiton rupestris is called the bottle tree. It grows a big fat water retaining trunk over time, somewhat like the Baobab tree from Africa.
Mahalo to Wikipedia for some of this info, I also referred to our old standard book: In Gardens of Hawaii, by Marie C. Neal.
I found out writing this that you can eat the fruit of cashews and its high in vitamin C and good for your teeth and gums.
Linda Neumann who has a farm on Kaua’i helped me learn more.
It would be a pretty, and fun fruit tree to add to our gardens. Lots of other useful and yummy things come from Cashew trees.
For years we had a Cashew tree growing at Foster Botanic Garden. It’s in the Economic section of the garden. In this section we grow plants with various economic value or potential such as herbs, spices, medicines, food, and even poisons.
The main thing we were taught about cashews, is “Handle with extreme care”. If it is not ripe enough, or too ripe Abunai! (Danger in Japanese) It is hard, and possibly toxic to harvest and process the hard-shelled seeds (nuts). You need to harvest at just the right time, and then extract the seed carefully. Juice from the shell around the fruit may burn your skin.
That is why I’m happy to buy this heart healthy nut at the store!
Interestingly the toxic principles in the shell may make a good insecticide! Research continues.
The Latin name is Anacardium occidentale, (“Ana’ means upward, and “Cardium” refers to the heart). Cashew is in the Mango family, Anacardiaceae. Cashews are native to Brazil and Tropical America
Relatives include Fruit trees like Mango, Wi or Otaheite apple, Hog plum (my Honey’s favorite, one grows and Fruits in Foster Garden). Christmas berry tree is related. Poisonous relatives are poison ivy and sumac, and the Marking nut tree.
Flowers are greenish yellow, fragrant and grow in panicles. Bees like to visit and pollinate the flowers. The trees can grow up to 40 feet in ideal conditions, we usually find shorter, wider trees here in Hawaii.
The fruit and nut are very interesting to see. The “fruit” that catches our eye is actually a “false fruit” or pseudocarp. Some call this a “cashew apple” Being Eurocentric they called all kinds of tropical fruits “apples”!
The actual fruit (botanically speaking) of the cashew tree is a yellow or red kidney shaped drupe that grows at the end of the cashew apple. The drupe develops first on the tree, and then the pedicel expands to become the cashew apple. The true fruit contains a single seed, which is generally considered to be a nut.
Aren’t plants wonderful and Complex?!
The attractive colorful and juicy fruit is an adaptation to attract fruit eating animals to aid in seed dispersal.
Although it is perishable, we can eat the fruit and make value added products like wine and fruit roll ups.
Cashew trees favor well drained soils and regular watering to get established. The flowers like it dry, just like mangoes. They benefit from leafy mulch. Keep turf grass well away from the root zone.
Today it is mainly grown commercially in Brazil and India. We do have some intrepid farmers in Hawaii who are growing trees and even selling products. I salute their courage. Farming and marketing etc., is not easy!
Recently my friend Kaui Lucas, who is a Trained Permaculturist, was talking to me about her Cashew keiki trees. She showed me these cute and vigorous keiki, that she is growing on her sunny lanai, protected with chicken wire.
Lucas got an email from the Department of Agriculture about a seed giveaway from Hinshaw Farms. She said “Frank Hinshaw is the cashew guy. He invited me to go visit, we could make a holoholo day out of that ! Super sweet guy and he was so helpful. The farm is at “Poamoho”.
A few years ago, My Friend Elizabeth Reigels and I went on a kalo and farm kokua, Gourmet Foodie and Educational event and on the Reppun farm. We visited a gorgeous tree that was loaded with ripe fruit. The fruit are very pretty and interesting to see.
This tree was so attractive and productive that it got me thinking cashew might be a viable crop for backyard growers and even for diverse mixed Fruit tree farms.
This would maybe be a good crop to grow more of in Hawaii. Especially if we grew it like old-time Hawaii farmers did, and like Permaculture and Regenerative Agroforestry plant scientists do now.
That is, grow a diversity of tree species, not a single Monoculture or plantation style. Layers of tall and short trees, shrubs, and groundcovers all grown together. Leave the leaves and let them naturally decompose and enliven the soil.
This diversity keeps the plants and soil health and helps capture rainwater and let it percolate down to our aquifer. It’s also more enjoyable to work in the Diverse cool shady spaces, cultivate and harvest than in a Monoculture, plantation, chemical using style of tree farming.
Besides eating cashews raw, roasted or salted, have you ever had cashew cheese? It is a bit labor and time intensive to make but it is so creamy and delicious. And it has less of some of the less healthy parts of yummy cheese: no cholesterol (since it is from a plant) and only healthy nut fats.
There is a farm in Moloa`a on Kauai with more than 200 Cashew trees. Linda and Scott Neuman started in 2002, are learning about which varieties grow best and how to harvest, dry and roast. Check them out online and buy some of their locally grown products. The Farm is called Neu Mana Hui farm.
They have an abundance of other crops too, including figs. Interestingly they used a ‘chicken tractor’, a mobile coop that lets the chicken’s control, and eat weedy grass and fertilize trees and crops too. Akamai, no?!
The oil around the nut is toxic and needs to be handled with care.
As Neumann says: “Our farm has 2 employees: my husband and myself. We do all the planting maintenance and production of our product. I have spent a lot of time trying to educate on the “toxic” product….
People get confused. Old school way is to throw the nuts into a fire and then crack to get inside. That smoke is toxic.
The cashew is fruit where the seed grows outside the fruit. The nut is the seed. The seed itself is covered by testa a covering like you see on a peanut. That protects it from CSL fluid which is in between the exterior shell and the testa. (cashew seed liquid)
That substance is used for many products in paint, brake fluid and other products. Some methods of processing capture the CSL we do not. The CSL will peel the skin on your hands.
We use gloves when handling the shells. A lot of people ask about growing cashew, cashew grow well in most areas of Hawaii, but the equipment is costly and difficult to obtain.”
The CSL fluid, or cashew seed liquid, and it has insecticidal properties (Makes sense no, since it would protect the seed from insects and grazing munching herbivores).
Traditionally the nuts would be thrown on a fire and smoked open. This smoke extremely toxic.
There is now an expensive machine to open the nuts safely. The Neumann’s do this and don’t bother with the seed oil
BUT what a diverse and useful crop for Hawaii’s future as we wean ourselves off toxic tourism. 30,000 visitors a day is way too many. Let us grow some nuts instead, and support local farmers, chefs, and True value-added businesses.
