Q. astilbe

I have 2 in large pots and live in central Minnesota. Can I just put them in the garage and should I water them and cut them back?

Let the plants die back naturally.
When they have gone dormant you can dress the top of the pots with a layer of leaves or some hardwood mulch. This will help with moisture retention.
When they have gone dormant you can move them to the garage.
Check the pots once a month to make sure the soil has not completely dried out. You can add a small amount of moisture if needed.
The key to wintering is to make sure the temperature stays quite constant.
Not cold, then thawing.

Q. Do deer like astilbe?

I know deer will eat most anything but there are some things they seem to like more than others such as hosta, hydrangea, etc. I was wondering if they seem to especially like astilbe.

Deer will eat almost anything when there's a limited food supply, so it's possible they will eat astilbe if there isn't anything better on the menu. I can tell you from personal experience that rabbits seem to love astilbe. This article may help you if you have a large population of (hungry) deer in your area:

Q. How to promote Astilbe blooms?

I planted Astilbe in my shade garden late spring/early summer. I have tons of leaves and they are very tall (12″ or more) but there are no blooms. They are kept moist due to the location; I hardly have to water them. I read now that compost should have been used to promote growth of the blooms. Is there anything I can do now to get some late summer blooms? I am in coastal VA.

You likely have high Nitrogen in the soil, which causes lots of lush greens but little flowering.
Phosphorous can be added and Bone Meal is a good way to do this.

Here is a few links for you.
