The Tropical Fruit Forum

Maybe it is Kai Apple? https://en.wikipedia.org/wiki/Kei_apple

I leave frost cloth on all winter. Pinned to the ground has been fine for me. It does breath enough to not trap the moisture.

Leaving it in place means that I don't have to check the forecast all the time.

Not yet. I have heard that they are supposed to take several months. I was also not on top of winter preparation and let them get down into the 40s*F which probably wont help my odds.

In my experience jackfruit seedling trees are more precocious than grafted trees and are much more vigorous.

Do I want a very vigorous tree? I have to keep it under 8 feet tall so that it is half way reasonable to protect it in the winter with frost cloth and heat.

One of my zone pushing projects is to try and fruit jackfruit here in Phoenix. I have direct sowed lots of grocery store seeds this summer and last, and I would like to graft something next spring.


I read somewhere on the forum that jackfruit in climates with a cold winter will not usually ripen the fruit in the same year that they flower, but that there may be varieties that will ripen the fruit faster. Maybe even fast enough to harvest in the same year that the tree flowered. Does anyone know of varieties that mature fruit quickly?

Assuming that small fruit would mature faster than large fruit I did some searching and came up with this list in no particular order.

• Nangka Mini^1,2
  
  • grafts relativly easily¹
• Cochin¹
  
• Honey Gold¹
  
• FAIR 1¹
  
• Rang Dashni¹
  
• Chirappuram Cluster Jack¹
  
• Gold Nugget¹
  
• Small/Mi Papi¹
  
• Golden Pillow¹
  
  • fruit as small as 3 lbs to 10lbs

The problem is that terms like "small" are relative and I don't know how small most of these are. I also don't know that small fruit will ripen any faster. Any ideas where I can find out how big these actually are, or if any of them ripen faster than others?

Won't that will have an affect on the accuracy of the reading? With the greenhouse effect and all.

A sensor like this will never give an accurate reading of the air temperature in direct sunlight with or without the cups. The cups would make it worse though.

Not in direct sunlight, the cups will slow down the heat transfer between the sensor and the outside air. This will make the temperature reading lag behind the true value a small amount (weak low pass filter). But I'm not running a high precision lab. I just don't want my plants to freeze. I don't think that the disturbance from the cups will be enough to mater in my case, but I hope they will go a long way to protect from moisture.

And use a garden var. If it is applied immediately after pruning, the wood on the cut will not cork and the wound will heal well without creating dead wood inside.

Is there another name for "garden var"? A google search only gives two results, both are products out side the US. Is this something that can be made instead of purchased?

I picked them up at Tropica Mango in Apache Junction.  He had one left ($60).  I also purchased a 15G Venus grafted to 13-1 from A Tropical Concept a month ago to test out.

Awesome! Thanks!

I have had some that I enjoyed eating that were grown here in Phoenix. It seems like it belongs in a similar culinary category as popcorn. It isn't something that you eat to fill your stomach. It is just something to munch on.

The Inkbird app gives me alarms as push notifications and audibly beeps too. Without an app store though, you won't have access to that function other than the audible beeping (you won't hear it indoors).

I may be overly paranoid, but that won't alert in the case of a power outage or tripped breaker right? Also, I think the push notifications won't work if there is an issue with the WiFi.

Congratulations! Always exciting when an experiment works

Did they say where they got their tree from?

Growing out this acanthocereus sp. from seeds from Brian Laufer. No fruit yet but hoping to get some flowers in the next year or two. I’ve treated them just like dragonfruit in terms of care

That's cool. I like the way some of the ribs terminate abruptly. I haven't noticed that before in a cactus. How old are your plants? Any idea how many years from seed before they fruit?
