Ok I did the experiment this afternoon.
Interesting! Do you have time & energy to repeat the experiment but eat the whole fruits instead of making juice?

Seems like it would be difficult to get plants out of an air pot with all the bumps and verticle walls.  You take a tree in a regular pot and turn it over and tap the pot and it slips right off.  I like to turn my plants over and slip the pot off sometimes to look at the root system and see if its time to up pot or plant out. 
Don't you just remove the "button" that holds the air pot together and then unwrap the sidewall?

Boooo  :'(, thanks for posting the update! I just ordered two Air Pots, and 7 Ultra Oxy Pots. I'm trying to get 10 pots from Litgrow, which would be the cheapest source. I'll run my own (no scientific) experiment to see whether I like this type of pot. I don't quite understand the huge price difference when compared to normal pots...

Very cool & impressive! Thanks for posting pics!

I don't want to send you away  :o but you're better off posting on http://www.bananas.org... Read there first, lots of posts dealing with exactly your question.

Here I see the limit of my English... ;)
Hey, you did great, plenty clear! I find it great that there are people from Europe and other places on this forum and if that requires some language bending and/or translation, then that's fine with me. I think it would also be fine to post a paragraph in duplicate in your native language.

Interesting: "Powerdrain Isostud must be backfilled within 15 days of installation to protect the membrane from prolonged exposure to UV rays."
At that price it's worth experimenting, though!

Well, so far the ones I've looked at state "do not expose to sunlight for more than X months" where X is pretty small. :-(
Did you get the Dörken Delta MS by any chance?

Oh, I misunderstood your previous post, I thought they were of freshly grafted plants  ::). Now it all makes sense. Thanks for the clarification.

Do I see correctly that the scion is a shooting tip with a bunch of fresh leaves? Do you do anything special in terms of watering before/after grafting?

Interesting, I'll have to see whether I can get that here. Looks like the type of product that US construction might discover in the next century...  :o

Update: I looked into the specs of two manufacturers and I didn't see anything about UV resistance, which makes sense given that these membranes are designed to be installed underground. I'm not a plastic expert, but as far as I know, UV resistance doesn't come for free, it requires relatively expensive additives. Plastic without such additives breaks down after 6-9 months in the California sun. Unless I'm missing something, that kills this idea for me  :'(.
i keep them outdoor and in full sun .The plastic its verry thin but on the most exposed parts looks like new,didnt discolored or lost flexibility.Only a single pot has a dimple that cracked and i toght its because of UV radiation but its not because its almost in the shade.If kept in a greenhouse then the UV its filtered or best would be to keep them in the shade .They are made for constructions and are a tough material.
Interesting. For how long have you had this stuff outside in the sun?

I found a way to build my own airpots from polypropilene plastic sheets used for construction( concrete casting) and they are put together with pop rivets.
What type of product did you use? I looked at concrete forms and couldn't find anything similar. What is the original use of the PP sheet?

Citrus General Discussion / Re: Bark inversion tutorial
« on: May 12, 2019, 02:05:58 PM »
SeaWalnut: no pain, no gain  :) Just pick a tree and give it a try! Or buy a cheap tree at a sale and try...

Joe: what is the impact of the bark inversion on the long term health of the tree? (I don't think the canadian power companies really care much about that aspect...) Doe it make the tree more susceptible to diseases? And how about drought tolerance? If the bark inversion restricts flow of nutrients it must also restrict the flow of other beneficial chemicals, no? I'm just wondering about pros and cons and what to watch out for... This seems really interesting for potted citrus, maybe I don't need to chase that elusive flying dragon rootstock after all  ;D

Thanks for the reference, now I'm trying to figure out how to get the full text, ugh. I hate Elsevier and that whole journal system...

Very interesting, thanks for posting! What is the failure rate one should expect?

We use our greenhouse to start plants for the veggie garden in february. We can get frost all the way to april and it's great to get such a head-start. Also, it's great to baby some small plants that go into the ground later, for example, I have a dozen citrus "trees" in pots there right now plus two dragonfruit. Come june/july the greenhouse is basically emptied and becomes an oven 'til the next cold season. If we had a more conventional property/house a lean-to with some shelving units with lights would probably be the most economical way to go.

After somme interesting discussions on Spaugh forum ,looking for ways to chill a greenhouse i allready decided on my dome chiling.I will make a transparent pad door onto wich a small ,really cheap and efficient pump will pump water on it.The door will be like a waterfall with holes like a sieve through wich air will pass assuring evaporative cooling.I also like the idea of having a waterfall door.
That sounds cool, so each time you walk in or out you walk under the waterfall and get a shower?

Interesting info. Has anyone got some links to the science behind the "maturing" or "curing" of citrus? Citrus is a non-climacteric fruit and also doesn't sweeten with added ethylene (but does change color). There's no starch to convert to sugar in the fruit... I thought that (to quote Wikipedia): "Once [citrus fruits] are separated from the tree, they do not increase in sweetness or continue to ripen. The only way change may happen after being picked is that they eventually start to decay." I'm sure I'm missing something, though  ;D ;D

Welcome here! In case you're not aware: you can get the persian mulberry in tree and bush form. Stay away from the weeping kind if you're looking for fruit production.

Thanks for the advice. I’m definitely looking for fruit.

I got a weeping one, because ... well ... never mind. Anyway, they get grafted high, like 5'-6' high, and then it's supposed to weep down from there. But it doesn't just do it, the weeping only happens if you carefully prune every branch every year. So the end effect is that the fruiting branches start somewhere up there in ladder territory and go higher. Plus you need to cover it with bird netting. Needless to say, I planted a bush form as replacement and that tree will come out once the bush has fruit. But 'til then I'm willing to do anything to get that fruit...

Yeah, isn't it true that whatever crazy stuff may be happening, a walk in the orchard brings the smile back?

Can you share more detail about the sprinkler and irrigation setup, especially for the younger/newly planted trees?

Nothing really special. I like the Netafim Supernet Jr sprinklers. They're used quite widely commercially but not so easy to source retail. I run a std 1/2" plastic irrigation tube down the row/terrace, and then plug in the sprinklers. I get the blue spreading discs with "short range" tabs. The tabs deflect the spray so only about a 3ft radius is covered, which is great when a small tree goes into the ground. After a few years I break off the tab as the root zone expands to get a ~6ft radius and I move the sprinklers a bit further away from the trunk. Two sprinklers per tree, or just one in between every two trees depending on how things work out. The latter is what is done commercially, but my crazy hillside terraces aren't that regular. In addition, I got special little deflectors that keep the water off the trunk. I can't get those anymore so I now use small binder clips instead. Doesn't seem to be so essential for citrus, more so for stone fruit.

Long reply, but the main thing for me is that I add mulch every year or two and I want sprinklers so the mulch gets rained on and decomposes. We have basically zero rain from about april to november. Plus, in sandy soil I don't believe that drip really works for trees due to the lack of lateral spread of the water.

I got some mislabeled Brokaw Hass trees a week ago at a retail nursery. The label said "clonal rootstock" but by talking to them I found out they're actually on zutano. They said that everything they sell to retail nurseries is on zutano. Whatever that means... probably price and keeping the clonal stuff out of widespread circulation.
After being miffed I ended up concluding that it really doesn't matter for me. I'm more than mile from any commercial Avo farm and on sandy soil, so the whole root rot and salinity stuff doesn't really apply. The issue is really replanting in infected soil. From the few papers I've read, it doesn't seem like the rootstock has much influence on productivity in Avos, I could be wrong though.
