I bought a dracaena reflexa a couple of weeks ago, in a rather good state. In less than a week it turned from seemingly perfectly healthy to practically dead and I would like some advice. Both in case this plant can be saved and because I plan on buying another since I really like this plant.

When I purchased the plant, I moved it to a new pot with new soil. I should note two things here, first of all the pot didn't have a draining hole. It does now but at that time I didn't have a drill. Secondly, the soil was the compact dried type that you add water to decompress. I initially used tap water but have switched to bottled water for watering.

Since I live in Scotland, the weather isn't ideal but the plant is inside, close to a window with some indirect sunlight at least.

The plant was perfectly fine for 2-3 weeks, and suddenly it started dropping good green leaves without warning. Then the leaves turned yellow at their starting point and started drooping.

The latest move I made was to remove the plant for the pot, discard all the soil, wash the roots and plant it again in the pot with fresh soil, using much less water to prevent the possible root rot.

Any advice would be greatly appreciated!
