Hi,
The handle is hollow and utmost care should be taken when soldering. I mean hard soldering, not with soft a low-temperature tin-based solder.
If the previous repair was done with soft solder there is a problem because tin residuals will prevent hard solder flow and hollow handle can actually deteriorate (burn) beyond repair. There is evident green corrosion and also dark patina to be completely chemically cleaned before soldering.
Successful soldering is not easy and it is done this way:
1.Cleaning of both parts
2.Fixing the handle to jardinière with steel wire in desired position
3.Heatng both parts close to desired soldering temperature with the torch (take care to not overheat ).
4. Apply flux to the joints
5. Apply solder either in form in small rectangles cut from solder sheet or touching the joint with solder rod under the torch.
6. When done, heat the entire piece again and the pickle it in diluted sulfuric acid.
7. Rinse with water and brush with brass brush
Pickling and brushing with brass brush will leave silver shiny white and I prefer leaving it like this because it will tarnish sooner ot later to desired antique patina. Just leave ut exposed to elements (polluted air and acidity in the air will do the job ).
