Do you want your gardenias to bloom all year round? There is a chance. You should know that they thrive in USDA plant hardiness zones 8 through 11, but if they’re a hardy variety, they can survive in zone 7. Gardenias are the perfect flowers for people who wish to add color to their homes. Their bright, bold blooms can stand alone or blend with other plants in your garden. But before you plant them, it’s important to know how they bloom and when they bloom. Here’s what you need to know about gardenias, when they flower and how to make them bloom all year.
Gardenia Bloom Cycle
There are two distinct seasons for gardenias: spring (April and May) and summer (July and August). Each season lasts approximately two months. So if your gardenias bloom in May, they will need to be repotted at the end of summer into a new pot. Then again during fall when their flowers begin to fade. That is why it’s best for these plants to have spent more than one year before planting them. But don’t worry about this too much because you can always give old cuttings or runners away with no guilt.
How Long Does Gardenia Flower Last?
Six to eight weeks after being picked, gardenia flowers can last for a long period of time. It’s possible that the variety of Gardenia planted and the condition of the blooms could impact this. Gardenias bloom for ten weeks, the longest known periods for a flower to bloom.
How To Make Gardenias Bloom All Year
Consistency is the Key
Gardens that are consistently warm and humid can trick Gardenias into believing that it is spring all year. Only gardenias grown in such an environment are susceptible to this trick. Gardenias are notoriously difficult to care for. It may take you a season or more to get the hang of Gardenia maintenance. The rewards, on the other hand, are well worth the effort. The Gardenia is one of the most beautiful flowers on the planet.
Water Your Gardenia as Needed
Check the moisture level in your Gardenia’s soil regularly to ensure that it remains moist. Water your Gardenia as soon as the top few inches of soil or the top one-third of the soil in the container becomes completely dry. The soil should be moistened with 1 inch of water for gardenias planted in the landscape. Water container gardenias until the soil runs out of the drainage holes in their bottoms, which should be every 2 to 3 weeks. If you allow your Gardenia to become drought-stressed, it may begin to drop its blooms and flowers.
Maintain the Humidity of Your Gardenia Bush
Spread a layer of organic mulch of two to three inches thick around the planting area of your Gardenia. But keep it at least 3 inches away from the plant’s base) to assist in the soil’s ability to retain moisture.
Fill a planting tray with pebbles and water for plants growing in pots to keep them moist. To increase humidity in the air surrounding the Gardenia, place a tray underneath the pot and allow water to evaporate into it. Use a misting bottle to mist your Gardenia every day if it’s growing in the ground or you don’t have a planting tray.
Provide Your Gardenia With the Exact Amount of Sunlight
Gardenias require full sun, with some shade provided during the hottest part of the day, to grow successfully. Gardenias grown indoors should be placed near a window with southern exposure to receive indirect sunlight.
Keep Your Gardenia As Warm as Possible
The temperature should be between 65-75° F (12.8-23.9°C) during the day and between 55-65°F (12.8-18.3°C) during the evening for gardenias grown indoors to bloom all year.
Feed Your Gardenia With Nutrients
Maintain the health of your Gardenia by fertilizing it regularly. Use a commercial 15-5-15 flowering shrub fertilizer on your Gardenia once every two weeks to keep it blooming and healthy. Alternate the general fertilizer with a special acid-based liquid gardenia fertilizer once every three months to ensure optimum growth. Follow the directions on the package application rates and amounts based on the size of your Gardenia. After fertilizing your plant, make sure to water it thoroughly.
