Gardenia fertilizer should be one designed for acid-loving plants, which will promote continuous gardenia blooms, according to the Univ ersity of Hawaii Cooperative Extension. Dilute 1 tablespoon of water-soluble fertilizer in 1 gallon of water for an outdoor gardenia, and use the diluted solution to water the plant once every one to two weeks during spring and summer.
The number of hours of light and darkness the gardenia receives can affect its blooming. Gardenias are short-day plants, which means they form buds when there are 10 to 12 hours of light and 12 to 14 hours of continuous darkness per hour cycle.
Artificial light during winter may prevent an indoor gardenia from producing flower buds. Heavy shade may prevent blooming during the spring and summer blooming season. In fall, a gardenia can be transplanted to a sunnier spot. Keeping as much of the root mass as possible intact, dig up the shrub with its roots, and plant the gardenia in its new location at the same depth at which it grew in its old location.
Pests and other problems can interfere with gardenia flowering, too. Aphids, for example, suck juices from leaves and stems and can cause gardenia buds to drop before they bloom. Dislodge tiny, wingless aphids from your gardenia by using a forceful stream of water from a garden hose, or remove the bugs by hand.
This ensures proper maintenance and feeding. Fertilize your Gardenia with an acid-based fertilizer once every three to four months. Gardenias should be sparingly fertilized in the spring after the risk of frost has gone. Then, in late June, fertilize your plants once more. Another alternative is to fertilize with a half-dose more regularly.
When a Gardenia refuses to blossom, it might be due to a significant insect infestation. Spider mites, aphids, scale, and mealybugs are all known to attack Gardenias. But the most commons are:. Aphids: These are soft, little insects that congregate beneath the Gardenia leaves and around fresh growth. They harm the plant by sucking its sap, and in severe situations, they can even kill it. Thus, stopping the flowers to grow. Whiteflies: These produce damage that is comparable to that caused by aphids.
Plants that have been infected grow stunted, their leaves become yellow, and they finally die. Honeydew is also excreted by these insects, which promotes the growth of sooty mold fungus, killing all the fresh buds.
Mildew with a powdery appearance is the common disease visible in Gardenia. Powdery mildew causes a white, fuzzy, or powdery covering on the leaves of Gardenias, and distorts any new growth of flowers. This illness is caused by inadequate air circulation, which causes dampness to build up around the plants. Thus, allowing mildew spores to germinate. To keep aphids at bay, use insecticides around your Gardenias regularly or neem oil.
To keep whiteflies away from your Gardenias, use insecticidal soap sprays. Thin out the plants to improve air circulation or move your potted Gardenia plants away from other plants. This helps in building control over powdery mildew in Gardenias.
Powdery mildew can also be effectively controlled with the use of neem oil. If you want your Gardenia plant to grow healthier and stronger flowers, then these are some other most important solutions. When dealing with Gardenia plants, there are a couple of things to bear in mind:. Gardenia plants grown from seed can take up to three years to flower, whereas softwood stem cuttings often bloom the next year.
Gardenias are evergreen blooming plants that are hardy in zones Their fragrant white flowers bloom from late spring to fall and remain for a long time. Before fading, each flower can endure several weeks. Most of the Gardenias blooms once a year. But depending on the type of Gardenia cultivars, a few of them can bloom many times in a year, such as their bloom buds appear in late spring, early summer, or even early fall. Coffee grinds, tea bags, wood ashes, or Epsom salts put into the soil would also benefit these acid-loving plants.
Coffee grinds are a better homemade Gardenia fertilizer since they are high in nitrogen, magnesium, and potassium. All you have to do is be more cautious, attentive, and compassionate toward these natural wonders.
