Tropical Fruit Discussion / Re: Subtropical suggestions for a 5 acre orchard
« Last post by Humboldt9aRiverBottomland on September 29, 2023, 08:30:59 PM »I used to go to college up in humboldt, so I got an idea of what the fog is like. Most of my experience thus far is with subtropicals one half zone higher than you. If you pick the right fig it should work for you, biggest things to consider there are figs that don't require high heat and full sun to ripen fruits. Probably Breba. Growers in the PNW would be able to advise you better on fig selection. I'm not sure how well a banana would do for you since you're in a colder area than I was, however online resources say the ice cream banana is hardy down to zone 8. Feijoa might work. The 22f would just barely kill a mature longan so if you feel like risking it it could work with some protection. Yuzu should probably work.Mulberry should work too, but I'm not sure how that'd do with low light. Oh and the right avocado should work for you if mature. I suspect this would take some babying the first few years.
Yup Humboldt has the coldest summers in the lower 48 states, with an average high of just 65F in Eureka. There's a fantastic "fruits of the Humboldt Bay" guide that says what does well right by the bay, including a couple fig varieties. I estimated the summer high at 80F but someone else told me it's 85F at my location. I'm right at the eastern boundary of the fog so I'm hopeful that I can have more success with heat loving stuff than the rest of Humboldt (and hopefully stays warm enough on my land). I'll probably stay away from stuff like longan until I get a greenhouse up. Thanks for your reply!
I would build a high tunnel if you want to grow sub tropicals in that environment. No subtropicals like it that cold , and most want it warmer as well.
Cherries and Figs can be tough too because , how many days a year are your temps in the 80's ? How foggy and close to the coast can play a big part.
If your too close to the coast and too foggy, It's hard to grow tomato's and you may as well plant artichokes and brassica's.
I can't wait until I get a high tunnel up. Do you know how much it might raise my summer high temp? I've found a few varieties of cherries and figs that are known to do well even right up on Humboldt Bay. I'm 30 miles inland right at the eastern boundary of the redwoods/fog, so I'm gonna plant a ton of stuff I know will do well, and roll the dice on stuff I start myself and graft at home, such as late blooming almonds. Thanks!

Mt Lewis Rescue, the higher elevations of Far Nth Qld mountains are misty cool, other worldly, magical forests. The tree foliage itself is quite beautiful.
Under threat from any rise in temperature.
Lowland Cairns has had heat waves in recent years. My friend said many palm trees around town dropped dead.
https://www.abc.net.au/news/2019-04-22/mountaintop-rescue-mission-to-save-threatened-plant-species/11021404
I wonder if the addition of Selenium to soils could help prevent palms and other species from dying in such a way. This year we had a pretty bad drought, and a lot of the Pona palms died suddenly in the area. And no, they did not receive a covid jab.

Tropical Fruit Online Library / What's The Deal with Syntropic Agroforestry?
« Last post by agroventuresperu on September 29, 2023, 07:53:04 PM »At first glance, it sounds like one of those "hey I've got the magic beans to make your landscape extremely productive even if Aluminum saturation is 90% and every nutrient is deficient in your soil" approaches.
The guy who coined the approach, Ernst Gotsch, seems to be a pretty intelligent person, although I get sleepy watching his presentations, and have to muck through his diatribes about the usual environmentalist gripes in order to glean a few nuggets of gold. What's missing is the hard data. Or perhaps it's not presented well and I haven't found it yet with my less-than-extensive internet searches. Most everything seems anecdotal, although it looks like a good approach to regenerative agriculture as far as I can tell.
Okay he started with a desertified piece of land with "soil pH from 3.7 to 4.5" in northeastern Brazil. What was the aluminum saturation? What was the CEC? Which species did he use in the areas that were pH 3.7? Did anyone conduct a geological assay of the soil using Inductively Coupled Plasma - Optical Emission Spectrometry? What elements were deficient?? Were any of these elements imported to the landscape in the form of amendments, fertilizers, manures, mulches, etc? Was any liming ever done during the reforestation process? What was the average annual precipitation of the area?
Hard to believe that a property that was a total desert with soil so poor that farmers "couldn't even produce a pineapple", was able to be converted into a thriving rainforest ecosystem without any irrigation nor inputs besides seeds and hard work - but that appears to be the insinuation. I guess if it took the guy thirty years to get to that point, it makes more sense. But I imagine the better part of the first decade saw little to no production, which wouldn't be practical for most people lacking a swiss bank account.
How does pruning tall trees effectively mine subsoil of elements? I can understand that, but what if those elements aren't there in the first place? Surely healthy populations of microorganisms can access unavailable nutrients, but I don't believe they have the ability to add elements that aren't in the soil profile or parent materials in the first place. If I'm wrong, someone please tell me there's a microorganism capable of the alchemy necessary to start adding gold to my soil. Now that would solve some of my problems. I have a lot of questions about this approach, which sounds like it's being marketed as a silver bullet solution.

Tropical Fruit Discussion / Re: Should I be concerned about this Cherimoya graft union?
« Last post by hammer524 on September 29, 2023, 07:45:33 PM »I'd be more interested in what the graft union looks like under the wrap. Is it fully healed? Cherimoya grafts are known to shrink and fail even with a few leaf flushes. Definitely protect that union so it doesn't snap off and as mentioned cut those rootstock limbs.
i didnt know that about the failed grafts after a few flushes does that stand for all annonas or only cherimoyas from you experience?
