What to Do When a Clivia Miniata Gets Stuck Flower Stems? The Latest Solutions Are Here

Clivia miniata is also known as sword-leaf stone garlic, large-leaf stone garlic, etc. It is a perennial herbaceous plant of the genus Clivia in the Amaryllidaceae family, native to southern South Africa, with very high ornamental value. In China it is often grown in pots in greenhouses for viewing. The so-called “stuck flower stem” refers to the phenomenon in which, when the Clivia miniata sends up its flower stem, the stem cannot emerge and is trapped inside the rosette when it blooms. Now let us take a look at what to do when a Clivia miniata gets a stuck flower stem!

Causes of Stuck Flower Stems in Clivia miniata

1. Temperature too low: The temperature for the Clivia miniata to send up its flower scape is about 20°C. If the temperature stays below 15°C for a long time, its flower scape will be very difficult to grow out.

2. Insufficient nutrients: When the Clivia miniata is forming buds and blooming, it has a relatively large demand for phosphorus and potassium fertilizers. A lack of these will lead to insufficient strength for sending up the scape and cause a stuck flower stem.

3. Lack of oxygen in the potting soil: During the bud stage, the root system of the Clivia miniata has a high oxygen demand. If the potting soil has poor permeability, oxygen deficiency will occur, causing the stuck flower stem phenomenon.

4. Constant-temperature cultivation: The blooming of the Clivia miniata requires a day-night temperature difference of 5-8°C. Constant-temperature cultivation will affect the accumulation of nutrients and very easily cause a stuck flower stem.

5. Root damage or root rot: If the root system of the Clivia miniata is damaged or rots, the channels for nutrient absorption will be blocked, affecting the plant's ability to send up the scape and bloom.

6. Poor variety: Some varieties of Clivia miniata are naturally prone to the stuck flower stem phenomenon.

What to Do When a Clivia miniata Gets a Stuck Flower Stem?

1. Adjust the temperature: The suitable growing temperature for Clivia miniata is 15-25°C. Below 15°C it grows poorly. In particular, if the temperature does not reach above 15°C before the scape emerges, the flower scape will be difficult to send out. Therefore, adjust the temperature in time to help the flower scape emerge.

2. Adjust the temperature difference: The growth habit of Clivia miniata favors a large day-night temperature difference. If the temperature difference is small, sending up the scape becomes difficult. After flower bud differentiation and before the scape shoots up, the temperature should be controlled at about 10°C, which makes shooting the scape easier; otherwise, the stuck flower stem phenomenon will occur.

3. Reasonable fertilization: After being grown for 3 years, Clivia miniata needs more frequent fertilization once autumn arrives. It is best to apply liquid fertilizer with a relatively high phosphorus content, and alternating applications of nitrogen, phosphorus, and potassium are preferable. When necessary, a 0.2% potassium dihydrogen phosphate foliar fertilizer can be added to promote flower bud formation and earlier blooming.

4. Timely watering: If there is a lack of water when the Clivia miniata sends out its scape, the growth of the flower scape will also be hindered and lead to a stuck flower stem. Therefore, when the scape is shooting up, increase the amount of watering and keep the potting soil moist; otherwise, the bulb and leaves will suffer from water shortage, blocking the plant's physiological activities and causing a stuck flower stem that affects blooming.

5. Cut open the scape sheath: When the Clivia miniata shifts into reproductive growth, pay frequent attention to changes in the bulb. If a stuck flower stem is caused by excessive pressure from the bulb, use a sharp knife to cut open the leaf sheath holding the scape by 1.5 cm to reduce the pressure of the leaf sheath base on the scape and encourage the scape to emerge.

How to Grow Clivia miniata Well?

1. Soil: Clivia miniata suits acidic soil rich in decomposed organic matter, and it should have good permeability and sufficient but not overly saturated moisture. It can be mixed from 65% humus soil, 20% clean sand, and 15% fine furnace ash, and the soil needs to be changed continuously during growth.

2. Fertilization: In winter, apply a solid fertilizer once to Clivia miniata, with less nitrogen fertilizer and more phosphorus and potassium fertilizers. A nitrogen, phosphorus, and potassium compound fertilizer can also be applied to promote the sprouting of more new plants and leaves, but fertilization must be moderate. Never apply concentrated fertilizer or raw fertilizer that has not been fermented and decomposed.

3. Watering: About every 20 days, Clivia miniata can be given fermented bean cake water, diluted fishy water, and water from soaked water chestnuts along with watering. When the room temperature is low, watering should be controlled to prevent the potting soil from becoming too wet. Too-wet potting soil will cause root rot and plant death, but the potting soil should not be allowed to become too dry either.

4. Temperature: The suitable growing temperature for Clivia miniata in winter is 15-20°C, and it is best not to go below 10°C. After the scape shoots up, the temperature should be kept at about 18°C, and the day-night temperature difference is best at about 10°C; otherwise, the flower scape will bloom before reaching the proper height, easily forming a “stuck flower stem”.

5. Light: Clivia miniata is a medium-light plant and does best with scattered light. It does not need strong light during growth, and especially in summer direct sunlight must be avoided. In winter, strong light during the flowering period will shorten the flowering period, while medium light can prolong it. If earlier blooming is desired, short-day treatment can be used.
