Contagion

Contagion is one of the heavy hitters of the mutation roster, carrying a massive x205 sale multiplier that puts it firmly in the elite tier alongside the rarest crop tags in Grow a Garden. A number that large fundamentally changes a sale: a single premium crop wearing Contagion can be worth more than an entire plot of ordinary produce.

Its exact trigger is currently listed as TBA, which fits its profile as a rare, likely event- or admin-gated effect rather than something you roll from common rain. When the condition is unconfirmed, the practical takeaway is that you should not expect to farm Contagion casually; mutations at this multiplier are almost always tied to limited windows or special mechanics, so availability matters as much as the number itself.

Where x205 truly shines is in stacking. Because crop mutations multiply together with size, Rainbow, and any weather effects already on the crop, layering Contagion on top of an existing high-value mutated crop produces explosive totals. If you ever get the chance to apply it, save it for your largest, most-mutated specimen rather than a throwaway plant. As a chase target, it is among the most rewarding multipliers in the game when obtainable.
