-Biomes have changed so that they take up a 4x4 area and so greenhouse biomes now can bleed outside of the greenhouse. Unfortunately, this cannot be mitigated (as far as I know). If you have a good imagination, you can say that the biome of the greenhouse influences the surroundings a bit and it is natural! So it's a feature, not a bug!
