The Tropical Fruit Forum

 Everything else is in the same potting media, made of coco chips, coco coir, and perlite with an added biochar.

Seems like a reasonable choice of pot mix components.
The ratio of these is important, in balancing water holding and air pore space.
None are completely inert, they all take up water to various degrees.
Some inert components, like quartz gravel,may give the same structure, but lower saturation.
Generally I stop at 33% coir for my mixes.
Most of the methods I mentioned are preventative or suppressive, although they might help recovery.
I would warn about trying everything at once to fix a problem.
Many nursery plants are grown and shipped with a dose of Fungicide to ward off problems, they might go backwards after it wears off.
A fungicide treatment sounds the best first option in your case.
It does sound like a possible problem with cutting raised plants ?


 

Plants in pots can be put higher up on benches. This will keep them in light for longer, out of shady sides or corners.
Also light from below will hit underside of leaves.
There is some use of white or reflective floor covers to bounce light up to leaves.
Some plastic greenhouse films are better at dispersing light, i.e. changing the path to more evenly use light throughout.

Yes I have grown seed. Highly true to type and vigorous.
Also a few interesting off types can appear. More like versions of Macrophylla.
It is not used much in Australia due to Tristeza, but I don't seem to have any trouble with it here.
Haven't tried cuttings but think they would root ok.

What a nut job! Why would anyone cut down their trees because the fruit got stolen by dumb kids?

Not necessarily Kids, but in my experience in Australia, it is not uncommon for fruit trees to be cut down to prevent someone else getting the fruit.
That's more so with people who don't eat or grow fruit and have no use for it. They just don't like people outside their fence even picking up fallen fruit.
Also they are spiteful of people who don't think like them and would eat something that they would not or didn't get bought in a shop.
I often sample fruit here and there mainly for propagation.
A Hi Vis vest is very handy for ''Official looking visits" to fence line fruit trees in daylight.

Since fruit fly got in here, many trees have been cut down, encouraged by Government to reduce overwintering hosts,
and by people who would cut down the tree rather than deal with the fruit every year.
Around here we have many Italian, Greek, Turkish etc families who grew fruit varieties.
As the parents and grandparents pass away, the varieties from home countries are being lost in the eradication processes.
In fact there was talk of local By Laws to prevent non commercial fruit growing in backyards.
This was also driven by Australian fruit growers who export fruit, Fruit Fly detection shuts the export market.

Finally on the Church/ Scouts issue.. I wonder if the order to cut the trees came from higher up, ( the Priest or Bishop ).
Maybe the were afraid of losing any more Altar Boys or Choirboys to the Scouts??
After all, when I was an Altar Boy, we only got reduced Pennance when we did something wrong. Never a badge when we did something good...

Is Rosso blood lemon a Lemon cultivar, Citrus limon, or something else ?
Maybe C.jambhiri ??

I am in a part of Australia where it is regularly 40'c to 45'c ( up to 110 f + ).
Mulberries are very tough, can handle this ok. The dense foliage is somewhat shading.
In fact they are great cool shade trees on those hot days.
However I do see your point overall.
Have you also considered dwarf cultivars of Mulberry, perhaps another way to overcome the problem.

Why Are So Many Seed Vendors So Dishonest?

Not totally in reference to tropical fruit species.
There is a level of skill and knowledge needed to harvest, store and despatch many seed types.
It is clear not all sellers have this.
Some aren't aware of seed lifespans.
There is an inherent failure rate in seed germination, even if everything is done right.
It can be hard to tell at what stage it went wrong, so failure is accepted to some degree.
Some sellers grow seeds, some repackage from other sources.
It is clearly a side business to some sellers, not a passion.
Buyers also lack knowledge about what they are buying.
Some seed sites are somewhere in the Psychedelic Fantasy range of what they offer,
Giant Blue Strawberries, Multi coloured grapes, photoshopped
( there are tricolour wine grapes on one bunch, but not that colourful).
Giant Sweet Pepper varieties, held in the hands of a very small lady.
Some buyers see these items and go Wow, and buy it.
After many years of seed collecting and growing I see this items and think WooooooooW. HaHaHa.

Australia.....No HLB so far.
Livestock farmers here are fretting because Foot and Mouth has broken out in Indonesia.
Bali in Indonesia is Australia's most popular holiday destination.

On top of that varroa mite, pest of honey bees has got into NSW at a port, from overseas shipping, spread further.
Beehive for pollination are restricted to be moved in some areas.

Possibly a Rangpur or Rangpur hybrid ?
Can you do a better pic of the foliage.
Could be Calamondin but hard to tell from foliage.
Both the above would have sour mandarin flavour more than exactly lemon.
Any reddish flowers or new growth tips.

I have a few Sweet Orange seedling rootstocks from purchased trees, that have fruited after the graft died.
The fruit are definitely oranges, nice sized but not sweet enough to bother eating.
They are not the Sour Orange species, Citrus aurantium but they are "sour oranges"
On the other hand some older trees around here are old Sweet Orange rootstocks. Fruit is fantastic, apart from the seeds.

Thanks for that. Are both those releases hybrids ? Wondering what the parents are ?
Guessing red fingerlime but one fruit looks like M.inodora too.
Also the Citrus parent ?

I recently found a fruiting Rough Lemon Rootstock in an abandoned yard.
The lower part of the tree had Navel Oranges growing.
Looks like a rootstock sucker has started to take over.
I ate an Orange, it was a little small and had tight skin.
Not sure of the actual Navel variety, early or late etc.
It is Navel Orange season here now, probably midway in the picking season.
The Orange flavour was quite acceptable, clearly orange.
It definitely tasted of Orange, not Lemon.
However there was a slight sourness at the end.
It wasn't the richest Naval Orange flavour, but it wasn't as bad as old oranges either.
Not sure how much this was due to the rootstock or fruit ripeness or lack of attention. ??
I will grab a few later and see how they improve.
