Cultivation of Clivia Miniata in Spring
Core content of this article: knowledge about Clivia Miniata cultivation at home, focusing on spring maintenance. Below, the editor will provide you with detailed explanations.
In spring, the gentle sunlight and suitable temperature are the best conditions for Clivia Miniata growth. Timely spring maintenance is crucial for the plant's development, flowering, and bud formation for the current year and beyond.
Appropriate timing for moving outdoors: Clivia Miniata that overwinters indoors should be moved outdoors for maintenance as the spring temperatures rise. The suitable time for moving outdoors is generally around Qingming Festival in temperate regions and about half a month later in colder regions. It can also be moved outdoors when the temperature is above 15°C. One or two days before moving outdoors, windows should be opened for ventilation. After moving outdoors, the plant should be placed in a sheltered and semi-shaded area first, and then moved to a sunny and well-ventilated place as it gradually adapts to the external environment, fully absorbing sunlight.
Repotting and dividing: The repotting time for mature Clivia Miniata is generally after flowering in spring, while non-flowering plants can be repotted when moved outdoors. Remove the old soil and dead roots after taking the plant out of the pot and replace it with new potting soil to increase nutrients and permeability. Established plants should still use the same size pot, while growing plants should use a larger pot. For plants with suckers at the base, having 3 to 4 leaves, and over 10 cm tall, division should be done during repotting. Suckers with roots can be separated from the mother plant with a sterilized knife, while those without roots can be pulled off by hand. Apply sulfur powder or wood ash to the wounds to prevent rot. Suckers with roots should be planted in small pots, while those without roots should be cultivated in fine sand first, and then repotted after rooting.
Watering and fertilizing: As spring temperatures rise and the plant enters the early growth stage, water requirements gradually increase. The frequency and amount of watering should increase from less to more, maintaining the potting soil moist. After the slow growth in winter, Clivia Miniata has few nutrients left, especially after flowering, which consumes most of its nutrients. It is necessary to supplement nutrients timely and appropriately to meet the requirements for spring growth and development. During the spring, when the plant is in the stage of producing new leaves and expanding leaf size, fertilizing should focus on nitrogen. Generally, apply a thin liquid fertilizer every 10 days after moving outdoors, adjusting the concentration based on the plant's growth and temperature. For compound fertilizers, apply a small amount around the pot edge.
Promoting bud formation and flowering: For Clivia Miniata with the habit of shooting in late winter and early spring, measures should be taken to prevent arrow lodging due to low temperatures or other factors, which can affect flowering. Two to three weeks before shooting, increase indoor temperature, increase watering, and apply liquid fertilizer every 7 to 10 days or a phosphorus-potassium-based compound fertilizer every half month. Water the soil with 20°C to 25°C water and spray the leaves with 25°C to 30°C water. Try to maintain the indoor temperature at 10°C to 15°C, which can promote the plant to shoot and form buds rapidly and bloom on time. Once the flowers open, reduce watering, stop fertilizing, and move the plant to a low-temperature area to extend the viewing period.
Disease and pest control: As temperatures rise, pests and diseases that are dormant start to become active and spread, affecting the plant's growth and development. Use 0.3 to 0.5 degrees Baume lime sulfur solution to spray on the plant leaves and bulbs every 10 days for 2 to 3 times, which can prevent diseases and kill overwintering pests.
