    Hi everyone. I have been using these methods in Saudi Arabia for more that a year now and have had amazing results. The same exact spices have been used. More lucina and siganporian daise. I will post videos on it soon to the channel. Very exciting to see that Geoff is recommending these trees and herbs as mulch and I’ve been lucky enough to be using them by chance.

    Thank you for all of your videos... especially the ones addressing dryland strategies. I live in Tucson, Arizona within the Sonoran Desert. It's definitely capable of growing more but the long drought we've been experiencing is a challenge. I've been following your advice for 6 years and I'm able to grow and keep alive more by mulching (rocks, wood chips, horse/cow manure/ chicken manure mixed with pine shavings). I grew 20ft Laucaena trees, so beautifully, but lost them during our winter and 3 hard freezes (zone 9b). They are slowly coming back in May. I plant vegetables in 15 gallon containers under mesquite trees so they receive some shade during heat. I like your perennial suggestion. I found Mexican Petunia's pretty and an easy to grow, self seeding (a pest at times) ground cover. It's been great for mulching. Love all of your videos, thank you and your team.

    For anyone living in AZ, I know that these methods are a lot about getting non-native plants to grow, but we actually have many native food plants! In fact, all 3 of our main native legumes: palo verde, ironwood and mesqute, are edible and delicious! So I highly recommend using them as shade, mulch and food while actively supporting native wildlife :) We have so many other edible native plants too like chia, cholla, prickly pear, saguaro, saltbushes etc! Im definitely not advocating against bringing in things like olives and whatnot, but adding in native plants whenever you can is a great way to support ourselves and our pollinators :D (Ps AZ has the highest diversities of native bee species in the US and possibly the world!)

    Are any students/instructors able to get into Palestine and teach those farmers permaculture? It's one thing they really could use..
    When I first saw that land, dusty, rocky, barren, I said to myself, "Wow, that's one challenge I don't think I could take on."

    Very informative. I have seen the benefits of this over the past 3 years. The soil in my yard is getting better at supporting more plants and grasses. I simply let the grasses grow without chopping it thru the rainy season, at which point I cut it all and made compost with it. This past rainy season, I did the chop-and-drop using the grass and the vegetables I grew are thriving, as well as some trees.
    Now I am using goat manure in and on top of the soil and mulch with the grass on top of the manure. I don't need to water as much, the soil stays moist longer. So I use less water to water my plants. In fact, I use water from cleaning utensils I give chickens water in most of the time now. My water bill hasn't gone up by much despite growing more plants.
    Compost tea from goat dung has percolated deep into the soil too and helps with improving nutrient profile of the soil. Worms are more plentiful too. Over the next few months after southern hemisphere winter, I will be planting lots of fruit trees finally. I hope to have a food forest in a few years in my yard.

    We're planning on how to use some of your techniques here on the ranch in Jalisco, Mexico. Fortunately we don't have so many problems with water, considering there's a rainy season that lasts for about 4 months, and also some natural springs on the property. Even so, many parts of the property get very dry during the dry season, so we hope to look at cultivating ground cover and mulching to keep the moisture in for the whole year.
    We're looking at the plants we can already find on the land to put to use. For example, we can get some equisetum from near the creeks and use it to make a reed bed for processing our grey water. There's also a herb which seems to be edible, which it seems the previous groundskeeper was using as ground cover near a banana tree. So we'll see if we can use that. Also some verdolaga/purslane which might be useful and tasty.

      You should consider the proliferation of huizache and mesquite because they are nitrogen fixers and are ubiquitous in Mexico. You are under the misconception that you do not have a water problem. Yes, you do. There two terms in Jalisco, estiaje and sequía. You do not use your spring for estiaje but only for sequía. You must rely on mulch and rain harvesting techniques. Here is a gastronomic 2020:13 suggestion: Beef mole, a side of verdolagas, 20:13 20:13blanched cactus garnished with freshly chopped coriander. There are many Tequileras inJalisco that need removal of the bagazo and vinaza. This perfect good mulch for you.

    I helped a cousin who lived in eastern Washington state turn his yard into a lawn. It started as hard-pan, and they'd tried putting mulch on it but that had only a negligible result over three years. What I did was till up the ground ten inches deep, then put six inches of mulch on top, then tilled sixteen inches deep, which mixed the mulch into the top layer of soil. What this did was give enough organic matter that the ground absorbed moderately quickly where before water had pooled and mostly evaporated despite the mulch on top. After one good rain where the neighbors' yard had standing water that mostly evaporated, my cousin's yard absorbed most of the rain. With another heavy rain forecast in a few days I implemented my next step: they had a rabbit which of course produced copious amounts of droppings that were high in nutrient content, so while the soil was damp we spread rabbit droppings in a layer about 3/4" deep and tilled that into the top eight inches. Since the ground was highly alkaline, and since coffee grounds could be had for free by the five-gallon bucket load, we mixed another 3/4" worth of coffee grounds with the rabbit droppings before tilling. After the next rain we bought enough "planting mulch" mix to cover the ground an inch deep; we mixed grass seed and some vetch seed into the planting mulch thoroughly and spread the result out evenly then tamped the surface down so it was smooth and level. He had to water it a few times through the summer but that was the last time; with the organic content in the upper layer of soil and a light addition of light mulch each spring that yard turned lawn became the envy of the neighborhood; it turns brown in mid-summer but becomes green again after the first rain (which sometimes comes in August!). The only things he added after the second year were corn gluten meal granules and coffee grounds. That lawn was a superb selling point when they got a new house!
    Anyway, I related this to point out that sometimes mulch on the surface isn't enough and tilling in a first batch of mulch to give soil fiber and the ability to actually absorb water can get things started. It isn't even necessary to till the entire area if you're just trying to green it (as opposed to making a lawn); in Eastern Oregon with the same sort of alkaline soil it's been show that tilling some strips or circles covering only a fifth of the area and tilling in compost/mulch is enough to jump-start things; once there is green plant cover on those portions the earthworms will slowly but steadily extend the borders, turning more and more ground into actual soil -- it's just necessary to keep the entire area well-covered in mulch (including coffee grounds; in small amounts the earthworms love them).

    The mulch is also very useful and important for organic growers in areas where there is plenty rain. Fungi will feed from the mulch, and provide plant available nutrients to the roots from the plants. Healthy plants will have a certain amount of sugar content that is high enough to protect them against insects. Insects are not capable of digesting those amounts of sugar content, that is why you will never see that healthy plants, living in a healthy soil with a high diversity of micro organisms, (fungi and bacteria) and enough bio mass from the right composition, getting attacked by insects. Fungi is for 70% the most important factor for a healthy plant growth. At least that is what I learned from watching this lecture, Why insects do not (and cannot) attack healthy plants | Dr. Thomas Dykstra | Regenerative Ag

Maybe even throw some rows of strawberries etc in raised bed containers and then run chickens free range through there in the warm months to eat the beetles etc off. then winter crop throwing buckwheat down on the pasture to green manure the rest of the 60 acres while the 4 acres (leaves and branches) provide feed for me and the goats. Still gotta figure some stuff out and probably will try to figure a hay for the bulk of the land... but if i can get something to be efficient enough on 4 acres i may just creep that to the horse barn area, main barns and house area and slowly work the bulk of the pasture like that until my seasonal creek basin is just 3 acres of prime hayland quality pasture/hay.
    Might be a pipe dream in the short term but if i can get somethings to go my way...

    Very interesting Geoff. Pretty sure the groundcover you are calling Caprobrotus is in fact Sesuvium portulacastrum, used a lot in the ME as an ornamental groundcover, as is Wedelia. A flower would soon tell which plant it is! Purple plant is a form of Ruellia, probably R. ciiosa. Very inspiring, I hope to initiate something in the UAE at some point.

    Be neat if you were or Mark Shepard were go to a conventional California orchard that someone is wanting to rehab according to permaculture practices. Always hear Californians whining about water rights.
    I'm 💯% certain there is zero or poor ground covers being used in most instances. Also see zero rainwater harvesting employed. It would likely be initially impractical to remove large portions of the trees out of production, to plant different trees and shrubs to improve diversity that way.
    It would be interesting to see how much impact a permaculture approach can have in these chemical- and irrigation-dependent valleys.

      Yup. I haven't driven past many orchards on the west coast where there's any ground cover, aside from some of them having grass that is manicured. I watched a church up the street from me do a replanting of Christmas trees. They only put down a thin layer of cow manure when they planted. Otherwise it is bare earth. Their trees appear to grow slowly and not be as "full" as they could be.

    Ruellia is the name of the plant with purple flowers. That stuff grows fast and can withstand heat and drought fairly well (I'm in Texas). Also, after they get a drink all the purple flowers open up and the bee's and humming birds love them. It can take over a space if not cultivated yearly, and its difficult to remove completely as it keeps coming back from the rhizomes that are left in the ground. I had to look up the name, we just call it "the bamboo looking stuff with the purple flowers."

  • @nekomancer9157
    @nekomancer9157 2 ปีที่แล้ว

    if you have a pummice like volcanic rock/ashstone you can use that as mulch because it will shade the soil keeping it cool and reducing evaporation, it will keep the wind from causing evaporation and the key factor of pummcie is that it doesnt transmit heat ie it insulates so also keeping the soil cool. this will allow you to plant pioneer species without any organic mulch available. if you cant get pummice get wide flat stones and lay them on the soil. they will also shade the soil but heat will eventually transmit through the stones as they heat up.

      Me and my dad planted 60 nut trees on our property in central texas late last fall, little did we know we would be in the worst drought in a decade here this year, we've gotten a few inches of rain this year at best and it's been well over 105 every single day for weeks now... what I can say from my limited experience on my 100 acres is that mulch is worth its weight in gold. Any tree that didnt get mulch dried up and died very fast. The difference between those with mulch and without is comparable to night and daytime. I havent watered in over a week and the soil underneath the mulch is still damp and about 20 degrees cooler than the ground around it. I forgot to mention that my soil is almost 100 percent shell rock that starts about 3inches down if that. I had to dig 2ft holes for the trees to even have a place to be put in with a rockbar. I know it maybe apples to oranges comparing solid rock to sand but I was pretty hopeless before discovering permaculture, now that I've implemented some of the techniques, I swear by them. Try your local dump ground or exposition center, anywhere that does rodeo's might be willing to fill up the bed of your truck with the cleanouts from the horse stalls which is great because it's got all them nutrients in it too. Dont sleep on the mulch though, it is my lands most powerful weapon in combating desertification

    Everyone in Greece is concerned with fire risk, with last year seeing 10's off thousands of hectares going up in flames taking livelihoods and homes with it.

      I would like to hear from others with experience on this.
      My thought initially is that mulching cools the soil and helps retain moisture which over time can refresh the water table so the plants have something to drink all year. Fire breaks might be of value to build into the layout of the land, but really, when the land is moist from the water getting planted in the rains and not evaporating or running off immediately, you would have a far smaller fire hazard.

      I think if you plant support leguminous species densely, you not only put less flammable mulch but after a year or two not only you will have a lot of shade which will also reduce fire hazard via increasing moisture in soil and organic matter and in soil but you also bring your food forest system a step forward and produce all your high quality nitrogen on site. in my experience there are some good ground cover plants which you don't even need to sow their seed and some are actually edible like lambs quarter. I think they also contribute to the fungi in soil as they are mostly "woody plants".
      of course you can use other plants that you want some plants as Geoff mentioned have "gels" that reduce evaporation and are fire resistant. not only that but you can use fire resistant trees as well there is video in Geoff's channel about how to fire proof your land, other than that using swales,dams, ponds high in the property obviously increase moisture in soil and help mitigate any fire risk.

      By implementing Geoff’s strategies you are helping to reduce overall fire risk by several different means. That said, there IS a greater chance of fire breaking out in a mulched permaculture site than on bare, scorched earth ground devoid of plants or any organic matter. It’s important to try to educate authorities and neighbors, as much as an uphill battle this can be. And to diligently design with the inevitable risk of fire in mind. The best way to prevent fire is to obsess over possible ignition sources and worst case scenarios, since the vast majority of wild fires are ignited by humans.
