I want to bring a bunch of crocus indoors. Do I have to put them in soil or can I take the bulb and put it in a vase with water? I would like this for an Easter Sunday table centerpiece.
The following article should be of some help to you:

What is the exact requirement of fertilizer for crocus per hectare?
Not sure on the per hectare part, as different brands of fertilizer have different strengths, but for crocus, you want to look for something a little higher in phosphorous to help with blooming better.
I received several plants for Easter and would like to save the bulbs and plant them outside this fall. I live in Michigan. How do I store the bulbs until time to plant?
You can go ahead and plant them now. They will not bloom this year but they will be fine in the ground.
If this is not an option, simply treat them as a houseplant until the foliage dies back, then place them pots and all in a dry place and let them dry out. In the fall, take them out of the dry potting soil and plant them in the ground.
If you leave the bulb in the ground throughout winter, will it come back in the spring? Also, do the bulbs reproduce each year?
It depends on where you live and what variety of bulb you plant. Say, a hardy bulb like a daffodil, the bulb replenishes itself after it blooms and also makes bulblets, which are small baby bulbs. These small bulbs will grow to full size bulbs and thus the dafodill bulb multiplies.
I Have Crocus, Nacsissus, Allium and Muscari bulbs that I bought last fall. I live in upstate NY. Can I plant any or all of these now, or do I have to wait for next fall?
You can plant them all now. They will not bloom this year but should bloom just fine for next year.
When do crocus bloom? I planted them in April and just found them in a move.
They bloom in the spring. Since you planted them in the spring, they will likely not bloom until the following spring.
We recently moved into a new house and the previous owners had a vegetable garden along with several flowers planted. One of those flowers is a crocus. How do you care for them once they are growing? How often should they be watered? I don't know much about gardening, so this is all new to me and I don't want to kill off all their hard work! Thanks for your help!
Crocus are easy care plants and established plants pretty much take care of themselves. Crocus prefer their soil damper in the spring and fall, but somewhat dry during the summer. Rainfall is normally enough for these little jewels but you may need to give them a bit whenever conditions in spring or fall become drought like.
