Only for about 5 minutes. Then lift the draining pot out until it drains, re-inserting after dripping stops.

Are the leaves fading, first? That would be a sign of over watering.

Try using baking soda and water and letting that sit on the pot for an hour or two before washing off and cleaning it as usual.

There are countless options to decorate a flower pot. You could use patterned napkins to decoupage, fabric for a collage, or use oil-based paints. Try using stencils and decorating with...

Make sure it's getting enough water and 6 - 8 hours of sunlight per day. You could also try giving it fertilizer once a week.

Yes. Since the plant is just a decoration, you can replace it with a fake plant if you'd prefer.

I don't think you should use a cast iron pan but it could work if you are desperate. I would definitely use a gas stove.

Yes, but it's better to plant in a small pot first and then transfer it to the larger pot.

Yes, you can. I have two growing in pots right now. They have survived two zone 6 winters, sitting right out on the patio with no protection.
