Can a houseplant fig tree be planted outdoors in Michigan?

Yes, a houseplant fig tree can be planted outdoors in Michigan, but it requires careful consideration of the climate. Fig trees are generally suited for USDA hardiness zones 8-10, while most of Michigan falls within zones 5-6. This means that if you choose to plant a fig tree outdoors, it should be a cold-hardy variety and may need protection during the winter months, such as mulching or bringing it indoors if temperatures drop significantly.
