Why doesn't a Clivia that has been grown for over 10 years bloom?

Every time I mention that a Clivia (Clivia miniata) will bloom once it grows more than 12 leaves and has been grown for 3-4 years, a gardening friend comes to ask me: Editor, take a look at my Clivia, how come it still hasn't bloomed after 10 years? I've tried everything like rice water and tea leaves, so why doesn't it work?

1. If it won't bloom, it's because you don't understand them well enough yet. Let's take a look together below.

Wild Clivia

The native habitat of Clivia is relatively moist, warm woodland. They usually grow under evergreen forests with scattered light, in places with well-drained, humus-rich small hillsides. Their habitats range from subtropical coastal forests to canyon highland forests.

Clivia miniata planted in the ground can grow into a very spectacular large patch. They enjoy a cool winter and warm summer environment. If given fertile, loose humus soil, their fleshy root system can grow as deep as 80 cm below.

Whether the leaves are in a regular fan shape or a scattered chive-like shape, they are all very appealing. Each stem can produce 15-20 trumpet-shaped flowers, each 5-8 cm (that's how big Clivia miniata flowers are).

Clivia miniata grows slowly and generally takes 3-5 years to fully mature. Each stem can produce one inflorescence, and the inflorescence is filled with small flowers clustered at the top.

Its fruit can be picked once it turns from green to orange. Remove the outer skin and you can sow the seeds. Its seeds have a pearly luster and can be sown while fresh.

2. Tips for caring for Clivia indoors

Clivia miniata is a familiar indoor plant for gardening enthusiasts. It can live for many years, grows easily, and is simple to care for, but it requires plenty of patience.

During normal care, avoid moving the plant frequently. Just turn the pot once a week. Wipe the leaf surface gently with a moist soft cloth every week to make the leaves more glossy.

If you don't want your Clivia to keep fruit after blooming, you can cut off the flower stem with a knife when the flowers are almost finished. Otherwise, it will affect blooming the following year.

1. Choosing the placement location

The best location for caring for Clivia miniata is one where it can get 3 hours of light in the morning and then another 3 hours of light before evening. That would be perfect.

The midday sun is too strong and will scorch the leaves of the Clivia. Remember, it must not be exposed to direct blazing sun. But if it is too dark, it won't bloom, and the plant won't be strong and healthy either.

In summer, you can place the Clivia in a shaded, ventilated environment, but it must not receive too much rain. Remember, do not let water accumulate.

2. Suitable temperature

In a warm environment, Clivia miniata grows extremely quickly. In winter, it needs a short dormant period (6-8 weeks), that is, keeping the temperature at around 10 degrees for 6 weeks, which can help them bloom better the following year.

If there is too much heating in winter, it may still bloom the following year, but if the winter is too warm, it will affect the timing of blooming and shorten the lifespan of the flowers.

3. Wateringand fertilizing

Avoid misting the Clivia too much, and especially do not let excess water remain on the leaves.

In spring and summer, you can give a bit more water. As much as possible, let the potting soil dry out completely and then water thoroughly each time. After it turns cool in autumn, gradually reduce the frequency and amount of watering.

But by late winter, once the Clivia has bloomed and has a flower stem, you should start increasing the watering frequency again. Be careful not to overwater, as frequent overwatering can cause root rot.

4. Potting soil and fertilizer

In spring and summer, you can give liquid fertilizer once every two weeks. It is best to use fertilizer specially made for Clivia. In late winter, appropriate additional fertilizing is needed.

The best soil for potted plants is loose humus soil with good drainage. A mix of leaf mold and wood shavings works well, and fertile humus soil is the best.

5. Introduction to repotting and potting up

Potted Clivia generally needs to be repotted once every 2-3 years, though of course it depends on the size of your pot. When repotting, clean up diseased roots, weak roots, and old roots. For Clivia that is over 3 years old, you only need to keep a little more than 1/3 of the root system.

When potting up, you can place broken tile pieces at the bottom of the pot and add base fertilizer to the soil, preferably well-rotted organic fertilizer. You can appropriately add some bone meal.

6. How to grow Clivia outdoors

If grown outdoors, Clivia needs a mild, frost-free environment. Clivia is very sensitive to frost and is especially easily damaged by cold in freezing wind.

Many people who grow Clivia on a large scale plant Clivia miniata under tree shade, in a dry, cool place with scattered light. The tree canopy can protect them from frost damage or sunburn.

7. Sowing and division

The most suitable temperature for sowing Clivia is around 21 degrees. It is best to use a seedling tray for care. Clivia grown from seed needs at least 3 years to mature and bloom.

When repotting, if you see side shoots growing from the Clivia, you can separate them and cultivate new plants.

3. Common problems gardening friends have when growing Clivia:

1. Pests

If the Clivia is harmed by mealybugs, scale insects, or spider mites, use an appropriate insecticide promptly. You can also wipe them off with a cotton swab dipped in alcohol, or spray with soapy water diluted in water.

2. Hasn't bloomed for many years?

If your Clivia still hasn't bloomed after 10 years, then ask yourself whether you have never fertilized it, overwatered it, and so on. (It is partially male and female.)

3. Root rot

If your Clivia shows symptoms of root rot, then you must promptly remove the rotten roots, let the wounds dry, soak it in carbendazim, and then repot it.

4. Spots on the leaves

If spots appear on the leaves, it is very likely sunburn, or it may be caused by light refracting through water droplets on the leaf surface. Otherwise, it is leaf spot disease. Promptly remove diseased leaves and spray with thiophanate-methyl. Too-wet potting soil or careless fertilizing can also cause this, so try to avoid it.

5. Flowers stuck in the leaf axils

When a Clivia's flowers are stuck, meaning the flowers are hidden among the stems and leaves, it is generally because the winter environmental temperature is unsuitable, usually too warm. Keeping it at around 10 degrees is the most suitable.

If the flowers are already stuck, then you need to provide shade, appropriately supplement a little fertilizer and water to avoid a lack of nutrients, appropriately increase the temperature difference, and improve the care environment.
