I have mushroom or fungus-like mushroom growing in and around my rhubarb. Is this good and how can I get rid of it and can my rhubarb be saved?
It is actually a good sign. Mushrooms like to grow in good soil. A little bit of a fungicide put on the ground where they are growing will get rid of them, if you want to.
The rhubarb is fine to eat, just make sure you don't accidentally harvest the mushrooms with the rhubarb.
I bought a rhubarb plant 2 yrs ago and the stalks are green. The plant is huge and looks healthy.

Will a freezing frost hurt rhubarb that is up?
Rhubarb is a fairly hardy and frost tolerant plant. If it is hit by a hard frost or freeze in late spring, it still can be eaten as long as the stalks are still firm and upright.
What happens if my rhubard got flowers and I cut them off? What will happen now?
If your rhubarb porduces a flower, this will not affect the plant other than sapping energy from its stem and leaf growth. Most people simply remove the flowers as they appear. If you already did this, your plant will be better able to focus its energy in producing larger stalks for you to harvest.
Do I keep the plant from going to seed by breaking pod off the top stem?
You can simply cut and remove the flowers as they appear to prevent the plant from seeding. If you already have seedpods on the plant, just cut them off.
