Steps to eliminate lawn leaf spot and melting out

Disregard - Double-post due to technical difficulties. Original post: https://ask.extension.org/questions/131664

I am reasonably certain that my Kentucky Bluegrass lawn is/was suffering from leaf spot and melting out. I applied fertilizer a few weeks prior coupled with the wet/cool weather and the signs/symptoms of the disease that I have read. I treated with Spectracide Immunox after an application of dish soap from a hose-end sprayer last Monday the 9th. The affected areas still have a water-starved appearence and are slowly browning in spots. I sometimes feel that the lawn looks like it is improving - but other times not. I cannot find the proper treatment steps anywhere on the web beyond chemical applications and methods to prevent reinfection. I don't know what to expect or what I should be looking for. Should I rake/dethatch the affected areas? Will the lawn die and have to be reseeded? I have been following the suggestions I found on the internet and have not been watering, have sharpened my mower blade and have been bagging clippings. Should I have noticed a significant inprovement a week after treatment? I have attached a couple of photos from before treatment. Any suggestions or information would be greatly appreciated. Thanks in advance.

Japanese beetles

This year was the worse! The beetles destroyed our flowers, grapes and apples. We want to wage war against them next year. I have read about using milky spore and neem oil to treat the adult beetles and grubs. Probably to late to do anything this year. Can you give me more information about applying these products for next year and where the best place to purchase them in the metro area.

Honey Crisp Apple Trees

I have three young Honey Crisp Apple Trees that were transplanted about three years ago. I believe that they had blossoms last year. This year none of the tree had any blossoms. I checked with the nursery where I bought them which is about 1/4 miles away, and theirs did not blossom either. Why would that be?

Shouldn't the shrub rose bushes be full of leaves now? Most of my bushes show dead stems but some have green stalks up to a point. There are leaves and buds on some stems so the bush is not dead. Only two out of eight rose bushes are full of leaves now with buds. Four of the bushes show new leaves near the ground but that is all.

Grass Issues......

Hi: I have a few problems with my lawn this season. First, we recently removed two large cottonwood trees. I filled the holes with new soil and planted Scotts EZSeed in the patches. The grass germinated and came in very well. However, recently those formerly nice growing patches have become brownish and seemed starved for water (See Pic Below). The confusing part is that when I water, I get a lot of mushrooms in those spots. I am assuming from the decomposition of the wood/stumps under the dirt. Any ideas on the new grass? Second, I have noticed that there are numerous small patches of dark green on the lawn too that look out of place (See Pic Below). Any ideas? Lastly, the removed Cottonwoods are throwing suckers up everywhere in the lawn. I have removed the larger roots where I can, but the clusters of suckers keep coming up every couple of days. I am now spraying them with Weed-B-Gon and waiting to pull them. The suckers have been wilting. Is there anything else that I can do? Thanks for your time. You provide a wonderful service. Regards, Greg
