Nicotiana paniculata grows best in loose, well-drained soil with some organic richness, which supports steady root growth and balanced plant health.

Soil Drainage
Well-drained
Native to Peru, Nicotiana paniculata comes from seasonally dry, open ground where soil drains freely and roots get good air. That background points to a loose, well-drained substrate that does not stay heavy or compacted for long.
The best soil for tobacco is sandy to loamy, with enough organic matter to hold some moisture without becoming soggy. Its root system benefits from a balance of aeration and steady moisture, which supports active growth while matching the plant’s preference for slightly acidic to mildly acidic conditions.
A simple homemade blend can give Nicotiana paniculata the balance of drainage and moisture retention it needs in containers.
The finished mix should feel crumbly and light, hold together briefly when squeezed, and let excess water move through without staying heavy.
A slightly acidic to near-neutral range of about 5.5–7.0 suits tobacco well. Within that window, major nutrients and trace elements stay more available to the roots, which supports even growth.
Nicotiana paniculata generally performs best on the mildly acidic side of that range, but it can handle small shifts as long as the soil does not drift strongly alkaline or sharply acidic for long periods.
This species can respond quickly when the root zone stays out of balance. Check the soil first if growth seems stalled or the surface is behaving unusually.
If the surface stays wet for a long time and the container feels dense, improve airflow in the root zone by blending in a lighter, coarser medium.
When water sits on top before soaking in, the structure may be too tight, so gently loosen the upper layer and replace part of it if needed.
If tobacco soil shrinks from the pot edge or dries unevenly, refresh the mix so it re-wets more evenly and supports steadier root contact.
A pale crust on the surface can point to mineral residue, so scrape off the top layer and flush with clean water if drainage is working well.

Yes. A pot with enough depth helps the root system develop more evenly and keeps the lower soil layer from swinging too quickly between soggy and dry.

Banana water can provide potassium and some nutrients that may support plant growth, but it is not a universal fix. Use it carefully and only when the plant actually shows signs of nutrient deficiency rather than as a routine treatment.
