Foamy patches that form in gardens and on lawns following a period of rain or after implementing freshly ground mulch are the fruiting bodies of slime molds. The patches might be almost any colour and are frequently described as resembling dog vomit. Slime mould is more unsightly than dangerous and doesn’t cause plant diseases. If left untreated, slime mold typically disappears on its own in five to seven times, but even this short period of time is too long to check at particularly revolting slime molds. Chemical therapy for slime mould is usually ineffective, therefore gardeners use mechanical techniques to remove slime mould without damaging the environment.
Mow lawns that are infested with slime mould to split and ruin the fruiting bodies.
Douse slime mould having a hard spray of water from a hose when the region dries to split the slime mould. Spraying while the soil is moist only encourages it.
Prune affected regions of garden plants to remove slime mould.
Rake slime mould on mulch to split it up or turn it under. Alternatively, you can lift it with a shovel and discard it or add it into the compost pile.
