- Grey mould patches develop on tomato leaves in the
greenhouse. It first appears as yellow patches on the leaf surface
with grey mould underneath. This can occur as as early as April but
more usually in June and July. The mould spreads to cover the upper
surface. Later on you will find the leaves turn brown and shrivel
but remain on the plant. Flowers and fruits may also be infected.
