Gardenias are popular shrubs and ornamentals in the southern division of the United States where severe cold won't mar the plants. Plants always come across to have more blooms at the time you receive them than any other time surrounded by their life due to smaller quantity than favorable growing conditions in most homes.
Gardenias thrive on 68-74 degree F temperatures contained by the day, and 60 degree F evening temperatures. Plants prefer full sun indoors; if grown outdoors for the spring, summer and impulsive fall, hold plants in obscurity. An east or covered west porch will be satisfactory.
High humidity is essential to gardenia thinking. Avoid misting the foliage, though, as leaf spot fungal problems will develop. The soil should be kept uniformly moist, but don’t overwater. A loose, well-drained natural soil is recommended.
Fertilize monthly between April and November with an bitter fertilizer.
Check regularly for insects and other pests such as aphids, mealybugs, spider mites, thrips and scales. Follow recommended control practices if pest problems occur.
The most irritating problem encounter with gardenias is "bud drop,"when flower buds abort only just before blooming. Common cause include low humidity, over-watering, under-watering, insufficient light elevated temperatures, speedy temperature fluctuations, cold drafts or redeploy in plant locations. In other words, gardenias are unstable!
Plants that do not set flower buds may be experiencing too much warmth.
Disease Problems:
Canker (fungus--Phomopsis gardeniae)
One of the most adjectives gardenia diseases, canker is identifiable by a main stem swollen hard by or below the soil line. The yelp also becomes corky and contains numerous longitudinal cracks contained by the cankered area. The stem above the canker is bright washed out in contrast to conventional greenish white. If the humidity is high, a yellowish substance may be see on the surface. Affected plants are stunted and die slowly. Destroy all diseased plants to prevent spread of the disease. Place brand new plants in a different location. Disease is smoothly spread on propagating knives.
Bacterial Leaf Spot (bacteria--Pseudomonas gardeniae, Xanthomonas campestris cv. Maculifolium-gardeniae)
Small, round ovoid spots on infantile, tender leaves are the first sign of bacterial leaf spot. As the spots amplify, the center is at first pale ashen and later become reddish-brown surrounded by a ashen halo. Margins of the lesion are thickened and water-soaked surrounded by appearance. Spots may coalesce to form large, irregularly shaped spots. Severe infection may effect defoliation. Avoid overhead watering. The disease is spread by taking cuttings from infected plants. Use sterilized soil and pots.
Rhizoctonia Leaf Spot (fungus--Rhizoctonia spp.)
Leaves infected with this fungal palm leaf spot disease have sunburn to brown spots up to 1/4 inch in diameter. Spots are circular and zoned. The disease begin on the older leaves and spreads upward when the plants are watered excessively or when nouns circulates poorly because of overcrowding. Diseased leaves should be destroyed and sterilized soil should be used. Disease-free plants should be used for propagation. Avoid wetting foliage when watering.
Leaf Spot (fungi--Cercospora spp., Phyllosticta spp.)
These fungi exact spots of various sizes on leaves throughout the year. Spots may be small, dark-brown necrotic areas surrounded by a pallid halo. In severe cases, premature branch drop may occur. Control is obtain by spraying with a folia fungicide at regular intervals.
Sooty Mold (fungus--Capnodium spp.)
Sooty mold cause black, thin layer of the fungus to form over the upper surface of the leaves. Sooty mold is caused by a fungus that grows on sugary exudates from white flies. Control white fly.
Bud Drop:
Bud drop, the out of the ordinary dropping of buds, occurs during period of high hours of darkness temperatures or during period of low light intensity. Some bud drop is a crude condition. Every effort should be made to hold on to the soil uniformly moist, but not wet, during flowering.
Powdery Mildew (fungus--Erysiphe polygoni)
Powdery mildew is characterized by white, powdery spots on leaves. Use preventive fungicide.
