Wednesday afternoon walk: The wilt aster flower of my friend

Hello everyone,have a nice day to you all.. yesterday afternoon as I went for a walk to get some exercise.. I passed by in the house of my friend, I notice the flower that we bought together last Sunday.. The flower are getting wilt already, so I decided to ask him what happen to the flower why is it getting dry and almost dying.. He told me that even him don't know why the flower is like that.. He always watered the flower in morning and afternoon but still the same that the flowers are slowly dying..

It's filaments are gradually turning brown and black and then its petals are gradually withering away also.. He said that the leaves started drying up and he noticed something yellow that look like an insect but he didn't know what it was and he just ignored it.. but as time went on it quickly withered the leaves and so did the flowers..

He tried making an organic insecticide to get rid of the small yellow insect he saw, but nothing's change, so he just let it die,, he also told me to check mine, maybe the same thing would happen.. so when i got home i immediately check my flowers and luckily my flowers were fine..

That's all for today,, hope you like my photos..😊😊

The pictures and texts are all mine..
