The trunk is whats left of last years growth so I don't go poking holes in the root bulb/knot thing in the spring while they are still dormant. Both the healthy and the unhealthy ones still have stumps, they will eventually break off the rest of the way for disposal and don't go below the soil / freeze line. I feed them several times a year with Chilated Nitrate(organic) and pelleted chicken manure, so nitrogen shouldn't be any issue. The critter on the bull-nettle is a common spider and there hasn't been any hail here in years. I can't imagine the sprinkler causing damage as it was hitting the trees directly last year with no signs of damage, not even yellow leaves.
I didn't notice the leaf miners before... I'm going outside again tonight to walk my dog and I'll take a closer look at them. They don't solve the asparagus and Moringa trees though.
In April of 2016, we had a 100 year flood and a month of rain afterwards but I don't see that being the cause since the summer and the rest of that year still saw vigorous growth, but I haven't ruled it out either. This year, nothing has any kind of vigor, except a few rows in the adjacent garden that so far has avoided this.
On some plants its like edge rust, others are missing leaves or the leaves are deformed, followed by necrosis, etc, on others like the nettle it browns from the outer edge. Dill turns brown, asparagus browns, Moringa leaves curl inward and yellow at the edges first, then yellow and fall off. As far as I can tell, its limited to the leaves.
I also have every pest known to man out here from swarms of leaf hoppers, stink bugs, shield bugs, squash vine borers, grasshoppers, snails, etc. No amount of pest control, weeding, etc, will get rid of them since I'm near a shaded water source and in the middle of a forest. However, they never caused any significant problems either. Crinkle virus is out and about but has only ever affected about five plants at most.
I suppose I should say the only plants not affected are nut-grass(common name / weed), and collard plants. Eggplant seem fairly resistant to it.
I used to. The mulch (woodchips) I still have lying around, have been used since last year and in both gardens, as well as newspaper. The woodchips I still have piled up (about 30 meter/yards away) are largely dark and composted. The other woodchips I used in spring of 2016 are from on-site when having electrical right-of-ways serviced(fresh). Most of them got washed away in the flood.
. I shifted to Johnsongrass hay from the neighbor which had weathered too long being rained on and was unsuitable for feeding. I discontinued that when I discovered it was the perfect haven for forest lice, snails, millipedes, centipedes, etc. It did do wonders for the topsoil though! The remaining haybales are for compost use with lawn trimmings, among other things. I inevitably chopped some of the woodchips into the soil while weeding so a portion of two rows are a bit slow to grow, even with supplemental nitrogen, but they were never diseased. The last time I added any kind of mulch to the garden was sometime last year.
Now all my mulch is sitting in a big pile away from the gardens and I'm probably going to use it as land fill for some of the weak spots on the levies or holes.
