The Tropical Fruit Forum

Hi
I've just found really interesting article https://solar.lowtechmagazine.com/2020/04/fruit-trenches-cultivating-subtropical-plants-in-freezing-temperatures/
What do you think guys? Is that possible and true or just fanciful and imaginary?

Hi everyone,
Like in the title of this topic - i want to push my hardiness zone and plant sth special that will provide tasty, high quality crop/food. I have on my property 3 places that can have high pottential to do that with really good microclimat.
Here are the photos of those :






First is probably the most protected and warm. It's small piece of land inside the household ambulatory/curtilage/cloister - I mean enclosed area made with all buildings around house besides small vehicle entrance which is "hole". As you can see from the north - sea - there is barn, from the West is byre and house and from the East is wood shed. The vehicle entrance is from the south- land mass- and also it's south exposition so there is plenty of sun. So far there is some old grape vine that doing very well.

Second is the lake. I guess there is some microclimats here bc of the water. There is some hedges/bushes from south, East and West, only from north (where photo Was taken) there is no bushes but in some distance - buildings. Maybe on the edges down to the center of that lake there is possibility for sth exotic?

And The third is south exposition Wall of utility room that belongs to that enclosed area in the First photo. Also plenty of sun. North is of course protected bc of that Wall, south no, west is house and east nothing but in some distance (not far away) there is willow Forest Wall.

So i'm curious what can be actually grown in those three places? Let Me know guys what do you think and your propositions for the most even extremely exotic plants that could doing well there. I Was thinking about some citrus, olive, acca,  loquat or even ... mexicola avocado.
Ps. I have in plan fig tree, persimmon and asimina in different places for sure so i'm not including them here.

On Canary Islands rainfall doesn't exceed 530mm (in the wettest place). Cacao tree need about 2000-2500 mm. I don't manage to foot the bill for water for cacao tree ...

Thanks a lot. As far as I know there is windy and rather dry. Is cacao tree which grow there needs additional water and shelter? Is that tree can be flowering and fruiting? Do you know where is the best place on this islands (south, north, west, east, on the coast, in the mountain, inland)? When cacao tree can be grown there, is cope there other tropical plants?

Thanks
 I wanted to lower it crown, because I don't imagine to use ladder to harvest.

I thought rather of rejuvenating cuts.

Hi
What if you put spiral pipes into the compost with an outlet on surface? Will there then be less work with heat distribution (in greenhouse)?

Welcome
I need your opinions or advices about compost heating . From what you can read on the internet, it is really cheap and ecological way to provide heat. The compost inside can reach a temperature of up to 80 degrees C. Do you think that in this way in 6b zone in winter you can heat a small greenhouse of plexiglas and polycarbonate (about 2m2)? Of course, this is not about high temperatures. The idea is to keep the temperature in the greenhouse around 5-7 degrees C, suitable for wintering olives, pomegranates, citrus plants etc. I choose this option because for me it is not possible to connect electricity and coal heating is unhealthy and quite dangerous.It is an effective solution? I look forward to your advice.

Best regards,

Jan

Hi
I grow exotic plants in a flat. Now they are standing under the lamp and wintering. Here are some photos of them :

Matisia soegengii :



Myrciaria sp. escarlate :



Graviola (Annona muricata) - August 2019



Browneopsis ucayalina (June 2019) - now it's ugly. Have you got some advice to grown this plant?



Synsepalum dulcificum (November 2019)



That's all for now. I will add more photos soon.

What kind of soil does persimmon need? In my allotment garden there is a sandy and clay soil. Is it good for my persimmon tree?

What does mean "astringent"?
Which of cultivars are astringent and which aren't  astringent and simultaneously can grow in Poland?
Which are healthier?

If its potted you can keep it in a garage or something.

  I'm afraid it isn't possible. My tree grow in ground.

I have never seen D. kaki in 6b and even the trees i saw in 7a did not look too good.
Why dont you get some tasty D. lotus variety? Tens of thousands of cherry sized persimmons per ature tree and in my experience much hardier than D. kaki.

This website http://przyjaznyogrod.blogspot.com/2016/12/diospyros-kaki-uprawa-w-ogrodzie.html convince me to plant kaki. In the plant nursery near me there were two cultivars to choose from: "Rojo brillante" and "Muscat". I chose "Muscat".
D. kaki are often grafting on D. lotus or D. virginiana, so even if it freezes, nothing bad won't become, because it will grow up with rootstock. What cultivars of D. lotus or virginiana do you recommend?
