Tropical Fruit Discussion / Chempedak disease - advice
« Last post by fruit nerd on Today at 08:16:02 PM »
Unfortunately, our chempedak is looking pretty bad at the moment. I've been noticing a bit of dieback recently but I just noticed yesterday that one whole lateral branch has died. As can be seen, it looks like fungus is growing around the top of the trunk. For a bit of background, I chopped the top of the chempdak out in mid-March last year to minimise wind damage from a cyclone. We have since had ~4m of rain with about 1m falling so far this March.

What do you think I should do? I am thinking of cutting off the diseased wood and potentially spraying the trunk with copper/wettable sulfur. Also, what is the disease? I'd like to do some research into the issue.

Thanks

I have sampled the roasted agave being prepared to ferment for Mezcal. It’s roasted underground for about 4-5 days. It is very tasty. I get the comparison to sweet potato but would say that it is much juicier and has fiber, almost like sugar cane. Surprisingly good!

My comments on the mediums has to do with two things.
What sort of soil would jabos naturally grow in.
What sort of soil will they eventually be planted in.
Seeds can produce roots that adapt to their media. For instance some people root cuttings or large seeds in water. The resulting roots are brittle and less suited to soil than seeds or cuttings started in a balanced soil medium.
I have never been to Brazil to examine the soil where jaboticaba occurs but we have good production in CR in clay soil, some of it quite acidic. My best jaboticaba in production is in a clay loam soil that doesn’t have any sand and has a ph of about 5.8.
For what it’s worth…

The JC Raulston arboretum in Raleigh NC has a marumi kumquat that was planted in ground in 2011. In 2014 and 2015 Raleigh experienced single digit freezes. In 2017 that kumquat was measured as 4 ft tall, indicating that it had not frozen to the ground recently, and was certainly not dead. 2018 saw an even colder winter with a low in the lower single digits. The website seems to indicate the kumquat is still alive, so I'd hazard a guess that, at least in the South, and probably in part shade, marumi kumquat is hardy below 10 F.

They also have a Dunstan that was planted in 2009. I can attest that in 2021 that tree was not only alive and producing fruit, it was also a good 15-20 ft tall.

If I may add, to the best of my knowledge it seems that the arboretum has misidentified most of their citrus with the exception of the Dunstan citrumelo. Their Citradia seems to be a Swingle citrumelo, their Ichang lemon is actually an Ichang papeda, and their Japanese kumquat may actually be Fortunella hindsii aka Hong Kong kumquat.
If these are in fact the correct varieties, it says a lot about the hardiness of Fortunella hindsii which may be greater than other kumquats. There is also the possibility they are planted in a good microclimate.

I believe it was a seedling tree from Ft Myers Beach, black skin, good tasting fruit  from a lady named Victoria. Fruitscapes is who propagated it, they may have better information. I hope my tree holds fruit this year for the first time. I was wonder if the original tree was destroyed in Hurricane Idalia.

I can only do trees in containers. I killed many a mango in pots in the past, I’ve got things working well now for my unusual setup, but  it’s seems a lot of work. I use a 50/50 organic peat/fir bark with about 5-10% worm compost and then mix that 50/50 with perilite (so 1:1:2). I use tall ceramic pots for improved drainage. I have the pots sit on big pots full of soil and wait for the roots to grow out the bottom before I pot up. I water with 75f distilled water from dehumidifiers mixed with very dilute 200ppm of fertillizer every time  I water. I Have them Sit in the driest and warmest area to avoid acanthranose and powdery mildew. Plants look healthy, no tip burn. My Florigon, orange sherbet, and Pickering all flower even though they don’t get under 60f.

There are people where u live who seem to have great success growing mangos with way less effort, but if u have a black mango thumb like I do I think this should work.

Best of luck

I'm growing Dialium indum-- are these worth growing in containers, or am I wasting my time?

I did one more prune on my Smathers WS today have have four scions (see photo). I’m thinking $4 each + $10 shipping so $26 shipped for all four.

Would also trade for certain Annona scions.

Cheers!

You growing them in a greenhouse inside or outside?
What's your soil like?
any more specs?
sorry about the lack of info, it is about 85% average humidity and about 72°f average temp inside the greenhouse . Im not sure about the soil because i received it from forum member Drymifolia who probably knows more than me about mango soils. I think it could be some kind of pathogen
