The plaster itself is not a food source for mold to grow on. Mold cant consume it. Plaster is non-porous and not organic. It is made with a lime or clay base and is very similar to concrete.

When You Do See Mold on Plaster

In older homes, those built in the 1930s and before, plaster was mixed and then spread over wood lath that had been nailed to the houses studs. If your home was built in this era, and the walls are original to the home, it probably has wooden lath behind the plaster. These wooden lath are susceptible to mold growth.
If the plaster walls are painted, especially with a latex paint, mold can grow on the paint, but most people just assume that the mold is growing on the plaster. Latex is an organic material and organic materials are a nutrient for mold.

Does Vinegar Kill Mold On Drywall

What Causes Mould On Walls
Black mould is often a result of condensation. When warm moist air comes into contact with a surface at a lower temperature, the moisture condenses on to it. After a while, mould will start to grow on the surface.
Condensation commonly occurs on surfaces such as windows and walls, in particular external walls. This is because they are often the coldest surfaces. Black mould will generally start growing in crevices and window sills and seals because there is even less airflow.
Its common to find black mould in the bathroom due to the high humidity.
Mould spreads incredibly quickly as it is an asexual organism. This means one single pore can reproduce trillions of mould spores in the space of a few days. Find out more about black mould here.

How To Remove Mold From Drywall
How the problem is handled on drywall depends on the condition of the sheet rock itself. If the material is unpainted or unsealed it is much more porous so it will absorb the spores right through to the back of the surface. In most situations, if you have a problem on the outside of sheetrock, it is probably on the inside as well. If you find it on unsealed sheetrock, the only thing you can do is remove the section that is affected and replace it. It is important to cut out a large enough section of the sheetrock to expose the wood behind it. Molds cannot be removed from insulation, so completely removing and replacing it is necessary.
