Gardenias

Gardenias are one of the most popular plants because of their exquisite, white, beautifully perfumed blooms which contrast perfectly with the dark green glossy foliage. They require warmth, shelter, well drained soil and plenty of water in the flowering months.


Gardenias flower best during the warmer months (late spring to early autumn). Their large fragrant creamy white flowers and glossy green leaves make them one of Australia's most popular evergreen shrubs.

USES:
Gardenias are versatile plants. Gardenias look impressive mass planted or as a hedge. Can be used as underplanting or background planting. Grows well in pots and can also be grown as a standard.

PLANTING TIPS:   
Plant in well drained soil to which compost or manure has been added. The root system is shallow and sensitive, so mulch generously with a quality mulch to keep plants healthy throughout the year and control weeds. 

Container plants should be potted in good quality potting mix with a high organic content.

SOIL: 
Gardenias require a deep, well-structured soil which has been enriched with compost or manure (cow or horse). They like acidic, cool, moist, well-drained soils. If soil is too alkaline it can cause yellowing of the leaves due to a magnesium deficiency. This can be corrected with an application of Epsom salts.

ASPECT: 
Require a warm, sheltered position, protected from frost. Early morning sun with light shade in the afternoon is preferential. Gardenias can scorch in full sun.

PRUNING: 
Prune lightly after flowering to maintain shape.

WATER REQUIREMENTS: 
Water well, especially in warmer months when the plant is flowering.

FEEDING: 
Fertilise regularly during the growing season. We suggest Harry's Gardenia Food.

PESTS & PROBLEMS:
Yellowing Leaves – usually a sign of magnesium deficiency and can be treated with Epsom Salts.

Bud Drop – This is when buds fall or drop off the plant just before blooming. This is most commonly due to lack of water.
Nematodes – can lead to leaf yellowing and may kill gardenias if not treated. 
Scale Insects – use white oil to rid the plants of these pests.
Weevils, aphids, thrip, mealy bugs and hawk moth caterpillars – use a general pest spray to manage these pests. We suggest the Yates Confidor Insecticide Range.
