Dragon Heart Cranesbill problems — and how to fix them

Dragon Heart Cranesbill (Geranium 'Dragon Heart') 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.

Flopping stems

Tall, trailing stems on vigorous plants can sprawl and smother lower-growing neighbours; insert twiggy pea-sticks or grow through an open-mesh hoop support placed in spring.

Geranium sawfly larvae

Greyish-green, spotted larvae create ragged holes in the foliage in late spring and again in late summer; check leaf undersides regularly and remove by hand to protect the display.
