Hi Har,Last year was the first year I got good flushes (about 4 flushes)I’ve noticed them growing from lower on the tree. The very top got badly roasted a couple years ago when we had a 116° day and has been kind of hanging in there but every year I would have to remove branches.Soil is clay. Based on research I did years ago I built a 4x4 planter out of redwood fence panels and mixed some native clay but also raised bed mix and sunshine #4 to make a fast draining soil. It is irrigated by in-line drip tubing coiled around the tree. This morning I proved around and found that not very close to the dropper the soul was significantly drier even though the irrigation ran last night (42 gallons over 6 hours, set to run every 5 days right now.)I believe a culprit lately has been our winds. It hasn’t been that hot, but the wooden slats with gaps and the loose soil could dry out easily with the winds we get here. Also my trees in clay do quite well with the drip emitters because the moisture spreads more evenly over distance. In the raised planter it just goes down quicker. Today I thoroughly wetted the entire root zone with a hose. I read a study on Pakistani mango growing on drip and they reported that soaking the entire root zone once a month brought tree production closer to flood irrigation. So I will monitor.Last year I gave my trees citrusgain once a month and they responded well. This year I’ve used to coated oscomote on my non fruiting trees and this year on the Vp just been using a drench of fish and kelp emulsion and humid acid kelp concentrate that works out to about 2-1-9. Trees get applications of pelletized gypsum and iron/sulfur in spring and fall. I should spray with Southern Ag citrus spray as I haven’t since right after harvestSummers here average very hot (90-100) and UVis intense and I’ve found this tree to thrive under 30% shade cloth. But maybe I’m not irrigating enough? Last year was good growth with increased irrigation.Sorry for the novel and thanks for you time
You didn't mean to say 42-gallons on one plant, did you?
Check with a magnifier lens, for mites. Or it might have phytophthora root rot. The stems already look shriveled.
Calusa,Deficiencies of Zinc and Copper.
Tonyma,Probably Mango Bacterial Black Spot. Or Anthracnose. For either, spray with any Copper product.
