Here, we demonstrate that both the CDW and magnetism of FeGe can be effectively tuned through post-growth annealing treatments. Instead of the short-range CDW reported earlier, a long-range CDW order is realized below 110 K in single crystals annealed at \\SI{320}{\\degreeCelsius} for over 48 h. The CDW and AFM transition temperatures appear to be inversely correlated with each other.
