Avocado farmer explains secret why you can't grow Hass avocado trees from Hass seeds

Did you know this?

An avocado tree farmer explains the science of Hass avocados

Have you ever seen anyone put an avocado pit in water to grow an avocado tree? I've seen lots of people try, but only a few succeed. My mom has a tiny avocado tree growing in her living room that she managed to grow from the pit of a Hass avocado she ate. It's small but thriving, and I've often wondered if it will ever grow actual avocados.

As it turns out, it could—but they won't be Hass avocados.

Wait, huh?

In a wow-that's-an-interesting-factoid-I-never-knew-before video, an avocado tree grower explains in this YouTube video why a Hass avocado seed doesn't grow into a Hass avocado tree. Avocados, apparently, are not "true to seed" plants, meaning if you plant the seed, you'll end up with a different variety of the fruit the seed came from. Apples are the same—if you plant a Fuji apple seed, you will not get a Fuji apple tree. In fact, chances are really, really high that you'll get an avocado or an apple that tastes terrible if you try to grow it from a seed of an existing fruit.

The guy from Sleepy Lizard Avocado Farm explains how it all works using an analogy with candy flavors. This is the genetics lesson we all needed in school when we were trying to figure out Punnett squares, and he explains it all so clearly.

Incredible how nature works, and so amazing what human beings have been able to figure out over millennia of agricultural advancements.

So how do you get a Hass avocado tree if you can't plant a Hass avocado seed to grow it? As he explains in the video, you can plant the pit and start to grow the tree, but if you want Hass avocados you have to graft a branch of a Hass avocado tree onto the stem of the tree you're growing.

Or, you can just buy a baby Hass avocado tree that's already been grafted, which is probably a heck of a lot easier than figuring out how to graft one yourself.

So go ahead and sprout that seed in water and grow yourself a pretty avocado plant if you'd like. Just don't expect any yummy avocados from it, since your chances are about 1 in 10,000 that it'll happen.

Thanks for the fascinating lesson, avocado guy!

A viral reminder that Native people are the historical experts on sustainability

Environmental catastrophes like the recent Australian bushfires and ecological travesties like plastic-filled whale stomachs serve as stark reminders of our precarious relationship with our planet. While many of us call for greater sustainability in all areas of life, we don't really know what that looks like—which is why we should listen to those who do.

Unfortunately, ignorance about Native cultures and history prevents many people from looking toward indigenous wisdom when it comes to environmental issues. Many of us tend to think of sustainability as something new and innovative rather than a way of life that has already been accomplished in multiple places by multiple peoples.

A viral Facebook post from The Audacity of the Caucasity illustrates this point beautifully. A screenshot of a post on tumblr shows three people's posts about how Native people didn't just live in harmony with nature, but actively and purposefully managed the land to meet their own needs while also maintaining healthy ecosystems.

RELATED: Still don't think climate change matters? Here's how it's hitting people where it hurts.

The first, from @downhomesophisticate, reads:

"I don't think a lot of people really understand that ecosystems in North America were purposefully maintained and altered by Native people.

Like, we used to purposefully set fires in order to clear underbrush in forests, and to inhibit the growth of trees on the prairies. This land hasn't existed in some primeval state for thousands of years. What Europeans saw when they came here was the result of -work-"

Then @feministdragon explained in more detail what that work entailed:

"The east coast was all mature and maintained food forests. Decades if not centuries of nurturing and maintenance. When the British arrived, they were amazed that there were paths through the forest just 'naturally' lined with berries and edible plants, like a Garden of Eden. Then they tore that shit down to grow wheat."

Finally, @worriedaboutmyfern shared what they'd learned from their mom, who happens to be an ethnobotanist.

"My mom is an ethnobotanist and getting people to understand this is literally her life's work. A lot of native tribes just had a whole different way of looking at agriculture. Instead of planting orchards in tidy rows near their villages, they went to where the trees were already growing and tended them there. They would girdle trees by stripping the bark in order to stop the spread of disease or thin out badly placed saplings. And they would encourage the companion plants they wanted and weed out the ones they didn't, so that in the end the whole forest would be productive while remaining an ecosystem and not a monoculture. It is still agriculture, but it is a form of agriculture that is so much gentler on the landscape that, as the OP says, the European settlers could not recognize what they were seeing. To them the natives must have seemed to magically live in abundance while they starved."

(The tumblr post also includes many more details about how Native peoples managed the land.)

While it's clear that modern life makes a total return to Native land management practices impractical, that doesn't mean we can't learn from indigenous wisdom. All of us will be impacted by an unhealthy planet, and it only makes sense to consult the historical experts on sustainable living to find solutions.

At the same time, we need to acknowledge that Native communities are disproportionally impacted by environmental issues. Oil pipelines are being built through Native lands. Indigenous people in the Pacific islands are having to navigate rising sea levels. Inuit communities are having to figure out how to move entire villages due to melting Arctic ice. Native environmental leaders not only have generational wisdom to offer, but an urgent need for all of us to take meaningful action.

RELATED: Laws and climate change are harming this tribe's foodways. Here's how they survive.

When prominent activists like Greta Thunberg tell the world to listen to indigenous leaders, we should share and heed that advice. We can learn about and support young indigenous activists on the front line of environmental issues. We can check out the initiatives of organizations like Indigenous Environmental Network and their allies like Climate Justice Alliance.

When we have a collective problem, we look to experts to help solve it. And when it comes to protecting the environment and maintaining a sustainable relationship with the earth, indigenous people are some of the most experienced experts we have.

Their neighborhood was in poor health. These amazing teens changed that.

True

In February 2018, a South Los Angeles community gathered to celebrate some local heroes: teenage agriculturists.

The event was the grand opening of a brand new, state-of-the-art greenhouse on the John C. Fremont High School campus.

This greenhouse is custom designed and optimized with the latest technology for plant growth and education. The vents are computerized. The blinds open and close by themselves, depending on the brightness of the sun.

This facility might sound like something you'd find in Beverly Hills. But it's in South L.A., which has the highest rates of poverty and lowest rates of health in Los Angeles County.

In other words, the place is unlike anything this area has seen before.

That's why city officials, community organizations, and local residents came together for the grand opening. It symbolized the growth of a neighborhood that was severely lacking green spaces and is now being transformed through healthy food and community.

The greenhouse is the newest addition to Fremont Wellness Center and Garden, which opened in 2012 on an unused lot at the high school. The whole project includes a community clinic, community garden, and small park, and the neighborhood youth are spearheading its mission.

When it comes to resources, South L.A. students and their low-income neighborhoods are overlooked far too often — but not with Fremont Wellness Center and Garden.

It began as a vision for safe and open green spaces as well as quality health services for students and the surrounding neighborhood.

So the Fremont Wellness Center and Garden's creators started the Gardening Apprenticeship Program — or GAP — which teaches students about gardening, environmental science, and food justice.

GAP currently only works with 14 students at a time. But with the addition of the greenhouse, students can participate in a Regional Occupational Program (ROP) as well. About 60 students can take part in ROP, making an even greater impact on youth in the community.

For inner-city youth who would ordinarily have to travel to wealthier neighborhoods for safe, green spaces, this opens up exciting new possibilities.

They learn about the social issues affecting communities like theirs and how they are amplified by a lack of access to fresh food. They also learn how to grow their own organic food, which helps improve their community's health and wellness.

"They learn more about agriculture and learn more about the field and get the professional experience to hopefully, one day, go into this field," says Keshia Sexton, director of organizing at the Los Angeles Neighborhood Land Trust.

And exciting events, like the greenhouse grand opening, allow the students to showcase their hard work for the community.

"It was definitely a student program and a student celebration for this new state-of-the-art resource that's now on Fremont campus," Sexton says of the grand opening ceremony. Presentations included a Fremont High School drill team performance and speakers from L.A. Unified School District, with photographers present to capture it all.

The program has been transformative for the youth involved, and one special speaker, Tiani, a GAP student, demonstrated that transformation.

"[She] spoke about how the program impacted her and made her a stronger advocate and gave her the confidence she needs to really succeed," Sexton recalls.

And she is not the only participating student to feel this way. The students' experiences and knowledge provided a crucial perspective on food equity. Their recommendations helped shape the future of their communities as well as offering expertise gained through education and lived experience with fresh foods.

"It's a healing space, and it's a space for folks to enjoy nature," Sexton says. "But it's also a learning space and a civic engagement space, where people are getting activated in being part of the solution for addressing the food inequity."

This program helps empower young people to be part of the solution, advocate for their communities' needs, and get healthy food growing in underserved neighborhoods that really need it. And their impact is already significant.

Their South L.A. neighbors now have new resources for healthier living within walking distance.

For example, the community clinic offers medical care for all ages at low to no cost, which will likely help improve overall health of the local population. The clinic is also hosting a free, biweekly farmers market open to the community. Healthy eating plays a critical role in preventative health care; nutritious foods can help prevent things like diabetes and high cholesterol.

It's no wonder these students are so proud to show off their work. This is an incredible model that could inspire resources for healthy living in urban areas throughout the country.

In South L.A., Fremont High School students now get to enjoy the fruits of their hard work. They're not only eating fresh food that they've grown themselves, but they're also realizing the impact that they can make on their community.

When imagining what it means to have green spaces in urban areas, most people might imagine a park or garden. But with a model like this, green spaces can be hubs of wellness, community, and education.

Chinampas: What they are, how they work, and why they matter today more than ever.

One of today's most innovative forms of sustainable farming is old. Like, really, really old. Aztec Empire old: chinampas.

With all the focus we put on technology, it's easy to believe that sustainability is a new-age idea. Scientists are frantically trying to develop something to save the world from our recent mistakes — the pollution of the Industrial Revolution, spills from any number of oil companies, and the human-made climate change that scientists only began to notice in the late 1900s.

In reality, one of the most innovative farming solutions has been here all along. Sustainable farming isn't a 20th century invention. It's something the Aztecs started doing centuries ago called chinampas.

The Aztecs used stunning floating gardens — otherwise known as chinampas — to grow their crops without harming the environment.

[rebelmouse-image 19533243 dam="1" original_size="800x562" caption="Photo by Karl Weule/Wikimedia Commons." expand=1]Photo by Karl Weule/Wikimedia Commons.

Chinampas were created by piling mud and decaying plants into small stationary islands on top of which the farmers would sow maize, beans, chilies, squash, tomatoes, and greens. Farmers would also grow the colorful flowers used in a variety of their ceremonies. To stabilize the islands, sturdy reeds were bound together and used to both border each chinampa and to help anchor it to the ground.

The dredging of the mud cleared the way for canals and naturally reinvigorated the nutrients in the soil that fed their crops. The resulting system of canals and gardens created a habitat for fish and birds, which helped maintain the health of the ecosystem and also provided additional sources of food.

The chinampas didn't harm the environment — they enhanced it.

This wasn't just a feat of incredible gardening — chinapas took a lot of complicated work to create.

Chinampas are sustainable, but they aren't self-maintained. Farmers had to construct a series of systems and processes to keep their people and the land healthy. Drainage systems were added to avoid flooding during the rainy season.

To fertilize the gardens, they developed a waste system to collect human excrement from the cities and spread it over their crops. The result was more than just flourishing crops: The chinampas actually helped prevent waste from entering and poisoning the water supply.

The fact that Aztecs found a way to turn unworkable swampland into a flourishing garden is an accomplishment in itself. Even more impressive is the amount of organized manpower, planning, and utilization of their resources required to make their idea a reality.

So don't call it a comeback. Chinampas have been here for years.

They're still in place around Mexico City, where they're both a tourist attraction and a working farm maintained by the locals. Other cities and countries have picked up on the chinampa idea, too — you can find them on the Baltimore waterfront and even cleaning up New York's polluted Gowanus Canal.

Some ecological companies have even taken elements of the Aztecs' methods and used it to create new technology that resembles the ancient version of the floating gardens. The sustainability benefits still appeal to modern gardeners — especially since chinampas can grow plants, clean and conserve water, and don't require large swaths of land.

The success of chinampas is a testament to the fact that sometimes the most innovative solutions don't involve looking to the future, but to the past.

The incredible efficiency of this indigenous gardening method serves as a reminder that sustainability doesn't have to be expensive or rely on the most advanced technology available to us today.

Sometimes, the best thing to do is to look backward — toward the people who figured out how to do it right the first time.
