Large-flowered Bacopa problems — and how to fix them
Large-flowered Bacopa (Sutera grandiflora) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bud drop from drought stress
Even brief periods without water cause buds and flowers to abort; plants show no wilting as an early warning sign, so check soil moisture daily and never allow compost to dry out completely.
Whitefly and aphids
Under glass or on sheltered patios, whitefly and aphids colonise the soft stems; introduce Encarsia formosa for biological control under glass or treat outdoors with insecticidal soap.
