Yes you will have to select a slower shutter speed or select higher ISO. I always opt for higher ISO. This is the major advantage a digital camera has over a film camera in my opinion, it is so easy to change film speed.
I work on the principle that the composition including focus and depth of field is most important. Then I worry about shutter speed. I like to use about 1/250th of a second on flowers to counteract my movements and the flowers movements. If I need a high ISO to achieve a good exposure with these two variables then so be it. I will underexpose and correct the exposure in post if I have to. A slightly noisy underexposed but well focused image is I believe always preferable to a fuzzy well exposed image.
I can't recall what camera you have but if it has the TaV mode, this is the best thing to use. I set it to 1/250 at f11 and let the camera work out ISO for exposure. Those settings are excellent as a starting point. Noise and exposure can be treated to a large extent in post processing, focus can not.
