There were bug problems but resolved by spraying diluted soapy water (Ivory) on all my plants. After that it just started dying? I don't know what's happening. Please help. Thank you.

Could it be too wet? Rosemary likes to be pretty dry.

What was the Ivory to water ratio? (I'm assuming Ivory dishwashing liquid rather than another Ivory product). I find rosemary growing indoors on a windowsill tends to dry out more quickly than one might expect but it's hard to say whether the plant is over or under-watered from the pictures. From the colour of the potting mix it looks more likely over-watering but it also looks like a gap between the mix and the side of the pot which would suggest too dry. Is the pot heavy for its size when you lift it or light? There's also white powdery looking stuff on the surface of the mix, could it have been given too much fertiizer?

Thank you guys for answering! Here are the answers to the question asked:
1. The ratio is 1 tablespoon of ivory (dish soap) to a quart of water.
2. Yes there is a gap between potting mix and the edge of the pot (about an inch deep and 1/2 inch wide). I will try to reduce the time of watering since there were no sunny days in the past week in Knoxville - I guess that's why.
3. It's not light like it's very dry. I only water when I touch the surface of the soil and it's dry.
4. I have not applied any fertilizer to any of my plants. I don't know what is happening.

Thank You!

If the white deposit is not fertilizer salts then I wonder if your water is hard? I'm not sure it is relevant, but why not fill in the gap between the rootball and the pot? I think the Ivory was maybe a little strong at a tablespoon to a quart but probably not enough to have seriously damaged the plant. I find rosemary a little finnicky as a houseplant, you don't want it to be too wet at the roots but it also hates to get too dry and can do so quite quickly on a sunny windowsill.

Was the soap solution rinsed off with water?
