Because metabolic processes are at a near-standstill in winter, plants cannot use excessive soil moisture whereas pathogens that function at lower temperatures can, thereby increasing the susceptibility of dormant plants to basal rot
and other fungal infections.
Some bulbs also suffer from basal rot
, a soilborne fungus, it spreads rapidly in warm, moist soil.
Or it could be basal rot
against which there is no control.
Any other fungal diseases such as rotting, or fluffy pinky-white basal rot
on daffodils is also a bad sign.
