Here's hoping...

Given that we're both very inexperienced gardeners and are very ignorant, I was sad to see the new nemesia looking much the worse for wear last week.

I think the problem was a lack of soil and water. So we rectified those problems a few days ago and it looks a bit better now. At least it hasn't actually died yet anyway! Any advice would be appreciated.

Hopefully another photo might show it in its full glory and having fully come back to life...
