How To Take Care Of Gardenia House Plant

Gardenia needs conditions with temperatures over 60 °F and no chilly draughts. Additionally, this plant demands a high humidity level of around 60%. During a cold, dry winter, indoor plants may need the use of a humidifier or continuous misting to maintain the right humidity.

Do gardenias thrive inside?

The common gardenia, which has its roots in East Asia’s tropical regions, thrives in its natural environment’s subtropical growth conditions.

When planted outside in the soil of a border or garden bed, it thrives in high humidity and will bud and bloom in places with temperatures that only dip to 55 to 60F at night and reach 70 to 75F during the day.

This species can be grown as a perennial in USDA Hardiness Zones 8 to 11 because it is relatively cold-hardy outside.

However, some of the more recent hybrids can withstand temperatures as low as Zone 7’s 5F or even Zone 6b’s wintertime average low of -5F. It can survive cold weather but not when temps drop below 10F.

Many gardeners in colder climates raise G. jasminoides in containers before bringing them inside to survive the winter. In our tutorial, you can find out how to successfully overwinter gardenias.

With a few additions to help them adapt to the limitations of containers and the dry air inside your home, they need the same conditions as they would if they were grown outside if you only wish to grow them as houseplants.

The requirements you must fulfil are as follows:


Your home’s thermostat should ideally be set to a lower temperature at night, but you don’t want to subject these plants to frequently changing air temps.

Put the pots in a location with a relatively constant temperature of about 60°F at night and 70–75°F during the day.

Avoid places with draughts and ones where the daytime temperature swings by more than a few degrees.


One of the most challenging elements of growing these gorgeous plants everywhere, not just inside, is this. They require around four or five hours of bright sunlight each day. However, they also wilt in excessive amounts of direct sunshine.

The optimum location has afternoon shade and morning sun. Place the plants on or on a sunny windowsill that faces south or west to give that indoors.

Additionally, take into account using a grow light on a schedule to supplement the light as needed, particularly during the shorter winter days.

Soil and Drainage

Make sure your chosen planting container has at least one drainage hole at the bottom, and add plenty of additional humus to the growing media to ensure proper drainage and moisture absorption.

Place a functional planter inside an attractive container that doesn’t have drainage and insert a saucer between the two to collect any extra water if the ornamental planter doesn’t have drainage.

For these acid-loving plants, the soil should also have a pH of 5.0 to 6.0. I advise purchasing a prepared blend.

How frequently should you water an indoor gardenia plant?

Gardenias typically thrive in full sun, but in the warmest regions of their hardiness range, they may benefit from shade during the hottest time of the day. They don’t seem to thrive in dry or arid environments and seem to thrive in humid environments.


Plant your gardenia bush in acidic (pH 5.0–6.5), humus-rich soil in the fall or spring, making sure to leave plenty of room for drainage. (Get a soil test if you’re unclear of the pH of your soil generally.) Plant in a large hole in soil that has been improved with compost or bark to improve drainage. Because gardenias dislike rivalry, make sure there is space for the roots to spread out. Also, after planting, try not to disrupt the roots. Gardenias grown outside do best in raised beds with good drainage and amendable soil; when grown indoors in pots, make sure the plants aren’t placed in a saucer or other area with standing water.

Watering and Mulching

Regardless of whether it comes from a hose or a weekly inch of rainfall, gardenias require water. Apply mulch to a depth of two to four inches to help maintain soil moisture and manage weeds that consume a lot of water. Water your plants frequently, and don’t wait until they are fully dry. The buds and leaves could fall off if you’re inconsistent.


Apply a dose of fertiliser made for acid-loving plants in the spring and once more in the middle of the summer, adhering to the label’s directions. Along with regular applications of fish emulsion or blood meal, which can help increase soil acidity, plants may also benefit from regular dosages of coffee grounds, which offer a mildly acidic mulch.


Don’t panic if your shrub’s heady, milky white flowers fade to a disgusting shade of brown; it doesn’t mean your shrub is dying. Just after flowering, the plant can be tip trimmed, but if you wait until August to do so, you risk reducing the number of flowers the following year by removing buds that are already growing. Gardenias shouldn’t require much pruning if they are growing in the proper conditions.

Winter Protection

Apply a thick layer of mulch over plants in the fall, right before the first frost, to shield roots from the brisk winter weather. At temperatures of 15 degrees Fahrenheit or lower, plants are susceptible to cold damage, therefore on the coldest nights, be careful to cover them with breathable cloth or other materials.


One of the simplest shrubs to root is the gardenia. Simply trim off the branch’s tip in the middle of the summer, remove any blossoms, and add a few lower leaves and water. Within days, roots will become apparent, and the cutting can be planted.

How to Care for Gardenias in Pots

The optimal conditions for gardenia growth are heat and humidity. You’ll need to simulate those conditions indoors. Your plants should be placed in a space with a temperature range of 55 to 75 degrees. Keep them out of the hot, direct sun, but provide lots of bright light. Grow them in pots atop trays of pebbles and water, use a humidifier, or spritz them to increase the humidity.

How can I ensure the health of my gardenia plant?

Gardenias are often cultivated outside where the winter climate is manageable, or grown in pots and brought within for the winter because they are cold-sensitive and may perish in harsh conditions. The gardenia bush should be planted in the fall or spring.

Regarding gardenia care outdoors, you should be aware that the plant often loves to be kept in some shade when cultivated outdoors. Gardenias also favour an acidic soil that is damp but well-drained and rich in organic matter. Gardenias should always be kept moist, even after the blooming has stopped. Once the gardenia bush has finished blooming, prune it to remove wasted flowers and unsightly branches and to maintain the plant healthy.

Healthy gardenia plants are more likely to survive the winter and frequently recover stronger in the spring.

Why is the gardenia in my home dying?

Gardenias are delightful to plant either indoors or outdoors because to their fragrant blossoms and shiny green leaves. The only issue is that they might be difficult to stay content, so you have to put in extra effort to appreciate them to the fullest. This article will help you identify the issue and restore the health of your Gardenia if it has started to die or appear a little unwell.

Root rot brought on by wet soil or over irrigation is the most frequent reason for a Gardenia’s demise. Despite the soil being damp, look for widespread leaf yellowing and wilting. A Gardenia’s struggles are frequently caused by pests, illness, inadequate light, and overfertilization.

How are gardenias kept from blooming?

In the late summer and early fall, gardenias create flower buds that will bloom the following year. Wait to prune plants until after they have finished blooming in the early summer to prevent removing these flower buds.

Pruning is often not necessary for gardenias. Cut back crooked branches and older, less productive stems to reshape the plant. You can always remove faded flowers. By late summer, plants will start producing flower buds for the following season; therefore, avoid pruning after mid-summer.

Should I trim the gardenia’s yellow leaves?

  • In U.S. Department of Agriculture plant zones 7b to 10, gardenias can survive outdoors. In USDA zones that are colder, they can be grown indoors.
  • When summer gives way to fall, gardenia leaves frequently start to yellow. When that happens, they might inevitably fall off the plant.
  • Springtime yellowing of the leaves could indicate a lack of iron. Instead of cutting them, think about leaving them on the plant as doing so might also remove flower buds. Instead, use an iron-rich fertiliser to feed your gardenia. In accordance with the size and age of your plant, follow the instructions on the packaging.

Do gardenias prefer sunlight or shade?

Location is the key to success because it is usually simpler to prevent plant issues than to solve them. The optimal conditions for gardenia growth are bright early illumination and afternoon shade. For flower buds to develop properly, exposure to sunlight is essential. Without enough sunlight, plants would grow slowly and bear few flowers. On the other hand, blossoms may fade quickly under excessive sunlight.

When choosing a planting site, take soils into account as well. Gardenias need a soil that is nutrient-rich in organic matter, acidic (pH 5.0-6.5), and well-drained. Give plants a lot of space so they can spread their roots Crowding and root competition are not acceptable to gardenias. To minimise pest issues, choose a site with sufficient air circulation.

Do gardenias thrive in containers?

In pots or containers, gardenias thrive and can enhance the beauty and aroma of a patio, front porch, or terrace. It’s simple to grow these aromatic evergreen plants outdoors in containers. They are low maintenance and just occasionally need to be pruned to maintain their size and shape.

One benefit of growing these shrubs in containers is that they can be readily relocated indoors or inside a cool garage or greenhouse if you live in a lower region where they wouldn’t survive the winter cold.

Is my gardenia in need of water, and how can I know?

Your shrub definitely needs additional water if it starts to drop flower buds or if the leaves start to dry out and wilt. Observe the soil’s surface as well; if it is dry and breaking, additional water is required. By probing a few inches below the soil surface and checking at the root level, you can assess your soil for dryness. This is particularly crucial when your plant is fully bloomed.

On average, gardenia plants require around an inch of water per week. Depending on where your shrub is growing, this might be raised. You might need to give your plant more water if it is located in a location with direct sunlight. Additionally, bushes planted near concrete or heated structures that warm the soil typically require more water.

What causes the yellowing and dropping of gardenia leaves?

Naturally, some older gardenia leaves may turn yellow and fall off, especially in the early spring when the newest leaves are just emerging. There is no reason to fear because this is typical. However, if a lot of your gardenia’s elder leaves are turning yellow, it may be dying from root rot brought on by overwatering or inadequate soil drainage. Remove it from the pot gently, or if it’s outside, remove a small amount of soil from around the plant’s base. The celebration is over if the roots you see are brown and spongy. Your plant has a chance if you uncover white, strong roots.

Low iron is the most frequent cause of yellow leaves on gardenias. But what’s this? To remedy the issue, you should test the soil rather of adding more iron. Gardenias require acidic soil, or soil with a pH of 5.0 to 6.5. Gardenias can access iron in the soil thanks to this pH range. You can change your soil’s pH by adding an acidic fertiliser if it is outside of those ranges. Use the fertiliser twice a month from early spring through late summer, or as soon as your gardenia leaves become green once more.

Gardenias are among the more difficult houseplants to maintain and can be difficult to manage as outdoor shrubs due to their stringent maintenance needs. You may enjoy your plant for many years to come by understanding what it needs to look its best and appropriately identifying any issues that do arise.

Gardenias thrive best where?

Gardenias are stunning subtropical plants, but they may be difficult to grow and have unpredictable cultural requirements. Make sure you adhere to the guidelines below if you want to successfully develop them.

  • Choose a location with strong sun to light shade. Although a Gardenia plant enjoys full sun, some shade is preferred during the hotter months of the year since too much sunlight can cause its leaves to scorch and its buds to drop off. Gardenias do well in hot regions with morning light and afternoon shade. They may survive full sun in milder climates, especially if their roots are protected by organic mulch. Container-grown gardenias require strong lighting or filtered shade, not direct sunlight. Indoor gardenias need at least 6 to 8 hours a day of direct sunshine coming in through a sunny window.
  • A wet, well-drained soil is essential for Gardenia growth. Every week, gardenias require at least 1 inch of rain (or comparable irrigation). Always keep the soil moist but not drenched. Gardenias need water, but don’t overwater them or the flower buds won’t bloom and might even fall off. Apply an organic mulch layer of 2-4 in. (5-10 cm) thickness to keep the soil moist and at a steady temperature. Use distilled water to irrigate the soil once each month to remove extra fertiliser salts.

What is the lifespan of a gardenia plant?

Older examples can easily exceed 10 feet in height, even though the majority of mature gardenias stay between 4 and 6 feet tall. With the right care, gardenias can live up to 50 years and grow into this enormous shrub. For instance, do not place plants close to gardenias to prevent competition for natural resources; vital nutrients must reach the stems, foliage, and flowers. Once you’ve chosen the ideal gardenia planting position, don’t move it around too much and mulch the base of the trunk. A minimal amount of ground disturbance promotes longevity. With a minimum overnight temperature of 60 degrees Fahrenheit, mild daytime temperatures up to 75 degrees Fahrenheit also promote long-term growth.
