I believe it is a watering problem. Do you check the soil before you water your plant? Make sure the top 1-2" are dry before you add more water. The soil should never be allowed to completely dry out, but it needs to dry some between watering. This is very important for the roots to breath. Roots require oxygen. They can not get it from soil that is ...

The bark looks like its on an ash tree, not an elm tree. Could this be correct? If it's an ash, then I suggest a bad (and fatal) infestation of emerald ash borer. I've seen this kind of bark loss all over the city in which I live - including on four of my own mature ash trees. It does look like you have borer exit holes in the last photo, particularly the ...

It's time to get your soil tested. You tested most of what that is to be tested. The the biggest reason for fruit drop is some sort of nutrient deficiency. I had suggest you use a Citrus or Palm Tree fertiliser because they have higher amount of certain micro-nutrient, but now I think you might as well test your soils before you go adding more fertiliser ...

The veins are all there. The picture you posted shows them clearly. It also show that they plant is needing some fertiliser. The entire leaf should be dark green not just the centre vein (see leaf in background for clear view of what I mean) The veins are dark green, but the rest is not. You want fertiliser made for either Palm Trees or Citrus Plants. ...

Look like the virus pictures I see. Streaks parallel to the veins. The other leaves looking good means it is not due to other growing conditions. looking at ref. https://www.researchgate.net/figure/Leaf-symptoms-on-canna-cultivars-between-8-and-12weeks-of-age-Cultivar-Aida-healthy_fig3_264671027 If url not working, search "virus on canna indica" and "...

According to the Royal Horticultural Society; 'Canna yellow mottle virus (CaYMV) & Canna yellow streak virus (CaYSV) both causes streaks of pale tissue between the leaf veins. These later die, resulting in streaks of dead brown tissue Bean yellow mosaic virus (BYMV) causes a yellow mottling of the leaves' I do not see either of the symptoms in your ...

Monstera Deliciosa are an interesting plant in the wild. They start out as terrestrial plants, but become epiphytic with time. Their seeds fall down to the ground, where the take root. The plant will crawl across the ground to the first tree. At that point it will 'climb' up the side of the tree. They can grow as tall as the tree 50', so they use ...

Over-fertilising is probably not the problem, unless you are giving it full strength fertiliser every time you are watering. Especially not a problem if you are flushing the pot every time you water. There is small chance you are under-watering that you do not run water through it long enough, but this is slim. I believe you are over-watering. I ...

Sclerotinia sclerotinorum, White Mold Without being able to see much detail, this particular fungus, White Mold may be what you have. It is rare for this fungus to bother mature trees but since your tree is still immature, this is another fungus to consider. Not at all a cool fungus. If this is a correct ID you have to be incredibly careful about ...

It is a fungus, but it's not harmless - unfortunately, this will have been at work inside your tree for quite a while, digesting the wood. What you see on the outside as these white deposits are the fruiting bodies because the fungus is mature enough now to produce them, and it is a signal that your tree is dying. If it is somewhere it can fall onto someone ...
