I have dug up my freesia bulbs and separated them. Is there a powder that I could or should apply to protect them from disease when in storage? Thanks.
Some people like to dust their stored bulbs with an anti-fungal powder. This is normally available at garden centers, though may be sold as a powder you put on plants like roses to keep them from getting black spot. This powder is fine for dusting your bulbs as well.

Typically these plants are propagated from offsets. This article has more information on collecting offsets:

I have many freesias which have finished blooming. Many of the stems have what appears to be new corms where the flowers were. Can they be planted and, if so, when is the best time to gather them (my husband thinks I should wait until they have dried, I think many of them will fall off and blow away if I do that)? Also, can I plant them now, or do I need to wait until fall? Thank you so much!
You can try to grow Freesia from the seed pods that form. It can be very difficult to germinate them.
I have had garden friends tell me that they just remove them and scatter on the ground or you can just let them naturally dry and drop.

I have freesias planted in a large trough. They started out as all colors and have now changed to just the one color. Can you please tell me why? They are now red with yellow throats and otherwise look and smell really good.
The article below will give you some reasons why flowers can change color. Some reasons include age, soil acidity, stress from transplant, and too much exposure to sun/heat.

I recently bought some Freesia corms/bulbs and I wanted to ask, is there any way of telling whether they are good or bad simply by sight or touch? Thank you.
Unless the corm is visibly rotten or smells moldy, I'm not sure you can tell except by simply planting them. See this article for proper storage:

I am in USDA Zone 10 and I planted some Freesia corms in containers a week ago. How long would it take for them to sprout? Should I leave the container indoors or outdoors? Thank you for any help, I really appreciate it!
You should see flowers 10 to 12 weeks from planting.

Do the leaves of the freesia plant stay green all year like an iris plant or do they dry up like a tulip after blooming?
If the Freesia are in a pot, you can allow the soil to dry once the flowers have faded. The leaves will die down naturally.
If you have planted them outdoors, the leaves will stay green for awhile after flowers have faded. You can deadhead the spent flowers and allow the leaves to die back on their own.
If you live in zone 9 and warmer the bulbs can stay in the ground. Colder zones you will need to lift the bulbs.
