I have a house fern that is about 100 years old. My question is that the fern is turning brown and I'm wondering what I am not doing right. I think it needs to be repotted but thought it would be better to do this in the spring. Could you please tell me why it is turning brown?
Normally, ferns this time of year are hurt by low humidity. Make sure that it is getting misted regularly and set it on a tray of pebbles filled with water. This will raise the humidity around the plant.
Is it true that scales can't be killed and they say just throw away the houseplant? Then I read about cooking oil dish soap and alcohol all together will kill the scales. Please help. This is the neatest houseplant I have. It's called 'Emina' fern.
Scale can be dealt with no problem. You can use these ingredients together to try to get rid of them (though the alcohol may hurt the plant, so it is best to leave it out). Here is the proper mix: https://www.gardeningknowhow.com/problems/pests/how-to-make-white-oil-for-an-insecticide.htm
You may also want to consider neem oil. It is very effective against scale and is harmless to people and pets. You can learn more here: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
I have had a box with three fern plants in my garage for three years. How long can these be stored?
It is not likely they survived 3 years. They normally can only stay dormant for about a year.
My fern is dropping its leaves. Might be that I let it get too much sun--they look burned. I have had it in the shade for days now and it is getting worse. Could it be something else?
It might have sun scald, which is like a sunburn for plants. There is not to much you can do for the damaged leaves. They will continue to turn brown. But keep it in the shade and watered as it should be and it should regrow the leaves.
Do you recommend any particular product to treat the rust disease on my outside ferns?
Transplant the fern plant or the fern bulb.

I am not certain what the exact name is of my fern, not a Boston, it has smaller leaves but sort of similar. I have no idea. Many have taken clumps out and had great success. I feel the remaining is very root bound. The water goes right through the pot and out the drainage hole. It's alive, and ok but doesn't seem to want to grow like it used to. What should I do?
Time to transplant to a larger pot. Use a good potting soil that is rather loose. Do not be tempted to buy cheap potting soil. YOu can either gently seperate the individual plants in the pot or just transplant as is. I generally just leave them because I tend to do damage to the roots if they do not seperate easily. It will still live but goes through an ugly stage where some of the top dies off (for me, anyway).
