Plant Growth
This spell channels vitality into plants. The casting time you use determines whether the spell has the Overgrowth or the Enrichment effect below.
Overgrowth. Choose a point within range. All normal plants in a 100-foot-radius Sphere centered on that point become thick and overgrown. A creature moving through that area must spend 4 feet of movement for every 1 foot it moves. You can exclude one or more areas of any size within the spell's area from being affected.
Enrichment. All plants in a half-mile radius centered on a point within range become enriched for 365 days. The plants yield twice the normal amount of food when harvested. They can benefit from only one Plant Growth per year.
Plant Growth 5e 2024 vs. 2014 edition differences
The 2024 version clarifies casting options (action for Overgrowth, 8 hours for Enrichment) and specifies only one Enrichment benefit per year. The 2014 version combines effects with different durations and does not specify a limit on Enrichment uses per year. The core mechanics of plant overgrowth and food yield remain consistent.
