Hope all goes well!before I go into the hospital
Copper plus the fruit tree mineral oil…spray in fall, again in spring. I did that this year and the trees are definitely looking better. One site where I was reading up on this problem indicated to spray at leaf fall ( in the fall), and they actually knocked off/removed the leaves still in the tree and immediately sprayed the copper/oil mix and never had a problem since. The trick is to spray before there is any growth at all in the spring. The fungus hangs out and infects the leaf as soon as it begins to grow. This fall I’ll try knocking off leaves (the trees are very small right now bc young) and spraying immediately.
I have a rhubarb variety (from Gurneys I think) called “Kanga-Rhu”. Grows in Australia and can tolerate up to zone 8 I recall. I’m sure that micro climate placement can also impact its success. It is growing well for me, but I’m zone 6. It does look quite happy in July and August too. It was around $30 for one crown, but it produced a “daughter” this year , as I discovered when I was reworking the soil this spring - another plant chunk just broke off on its own, so I planted it on its own. It is a smaller rhubarb, but tasty and red.We can't grow rhubarb here in the Deep South. Too hot...
