Help frangi­pani thrive at home

Life & Style Weekend - - GARDEN - with Angie Thomas Angie Thomas is a hor­ti­cul­tur­ist at Yates.

IT’S been a big year so far for scale in­sects. They have been at­tack­ing a mul­ti­tude of plants in­clud­ing cit­rus trees, shrubs like gar­de­nia and also na­tive plants, in­clud­ing the na­tive frangi­pani, Hy­menop­spo­rum flavum.

This beau­ti­ful na­tive rain­for­est tree is widely grown in home gar­dens in warm to tem­per­ate ar­eas, pro­duc­ing masses of sweetly scented white and yel­low flow­ers.

Scale in­sects can in­fest the stems and fo­liage of na­tive frangi­pani, lead­ing to yel­low­ing leaves and the devel­op­ment of sooty mould (which is a black, ash-like layer that grows on the sweet honey­dew that sap-suck­ing scale in­sects ex­crete and can cover stems and leaves).

Scale can sig­nif­i­cantly af­fect the health of the tree, leav­ing it look­ing ab­so­lutely mis­er­able.

Scale in­sects can be con­trolled with oil-based sprays. Cover as much of the na­tive frangi­pani as pos­si­ble (a step lad­der might come in handy if the tree is large – be care­ful up there), en­sur­ing stems and up­per and lower leaf sur­faces are cov­ered. Sev­eral sprays a few weeks apart may be re­quired and dead scale can re­main on the plant for a few weeks af­ter spray­ing.

Cor­rea ‘Catie Bec’

Cor­reas are gor­geous Aus­tralian na­tive shrubs that have cap­tured the eye of clever plant breed­ers. Some­times called na­tive fuch­sias, they have bell-shaped flow­ers that now come in some re­ally lovely colours, in­clud­ing bright and del­i­cate pink, or­ange, pale green and white.


Al­though hardy, frangi­pa­nis can at­tract scale in­sects that dam­age their leaves and flow­ers.
