the epsome salts i use in the flower beds is mixed with other things and i only use1 cup of salts. and they are dispursed throughout all of my flower beds.( and thats a lot!) thank yall for your info on this issue with the salts in the pots. when i spray a bug spray, the plant gets moved into the dark and then sprayed. they stay in the dark corner for 24-36 hrs before i put them back into the sun. that way there is no chance for burnt leaves, i learned that the hard way when i first became interested in plants, that seems like forever and two days ago...lol. i appriciate all the help you guys have been.
