I have a large Ginger plant and an Anthurium that have brown edges on the end of some of their leaves. They are outside under a tree in partial sun/shade. Most of the leaves are green and they look happy and healthy. I bought them about 6 months ago as 'leftovers' for 75% off because they were not in perfect condition. The new growth is green and hasn't turned brown yet.
This is probably due to poor care that it recieved before you bought it. If the new leaves look healthy, then you have nothing to worry about. You can trim off the brown spots and edges if you would like for aesthetic reasons, but it is not necessary.
Is white ginger the same as the spice? Looks the same. The white ginger I have in abundance has a white flower with a pleasant smell. Its roots look like the ones found in the grocery stores. Is it safe to be used in cooking?
It is not edible. While they are related, white ginger is not to be used for cooking. It won't kill you, but may make you feel unwell.
I have new white butterfly ginger. They are about three (3) ft high and have some old blooms on the stalks. What do I need to do to keep getting new blooms and not destroy the plant?
Old stems should be pruned back in late winter/early spring. This plant flowers on each season's growth, so pruning old growth will help encourage new shoots. Remove the stem, leaving a few inches above the ground.
I bought 3 variegated ginger lilies. Two of them have developed brown spots or new developing leaves are brown. What is causing this? Also, I thought variegated ginger lilies were a deeper green/yellow, but the ones I bought are a faded yellow/green. Why is that? Thank you for your assistance.
It sounds like your plants have a fungus. Treat them with a fungicide. The off coloration is due to the fact that they are under stress from the fungus. They should return to a normal color when the fungus is gone.

I have some ginger plants in my garden which have died. I was wondering if I just left them there would they grow up back again?
Unless you live in zone 10, ginger must be dug up in the winter or it will die in the ground.
