Commn Flower Problems

Aphids are the most common of all pests and almost every plant from the smallest shrub to the tallest oak tree can be infested. Find out the other top common flower probles below...

Aphids

The most common of all pests and almost every plant from the smallest shrub to the tallest oak tree can be infested.

Further details on aphids.

Earwigs

A pest that eats the developing buds of chrysanthemums and dahlias. These bugs cause damage to plants as they eat the young leaves and flowers. Damage is most easily recognised as irregular holes in leaves and petals.

Grey mould

This is an extremely common fungus and grows on many plants. As the name suggests a greyish fuzzy fungal growth develops over the infected area.

Rain Damage

Causes ‘balling’ of flower heads.

Red spider mite

Perhaps the smallest of the common sap feeding insects. Leaves first develop a pale mottling but as the infestation progresses so the leaves become increasingly yellowish white.

Further details on red spider mite.

Smuts

Small dark spots on stems. Larger dark swellings again on stems often accompanied by leaf distortion. Sometimes swelling and distortion of a flower’s stamen. Black sooty powder.

Further details on smuts.

Thrips

Thrips (sometimes called Thunder Flies) are yellow-black, very thin and about 2mm long. Yet another sap feeding insect but one with a difference. This one will happily feed on the surface of a leaf.
