Detailed Explanation of the Causes and Treatments for Yellowing, Scorched and Curling Leaves of the Bird of Paradise

The bird of paradise (Strelitzia reginae), also known as the crane flower, stays evergreen all year round, with graceful form and a unique appearance, and is deeply loved by people. It can be planted in clumps at the corner of a courtyard and used for courtyard landscaping and as an accent in flowerbeds and flower borders. However, during care, the phenomenon of leaves turning yellow and curling can occur, so what is going on with yellowing, scorched and curling leaves of the bird of paradise? Let's take a look together.

I. Causes of yellowing, scorched and curling leaves of the bird of paradise

1. Excessive fertilizing

Many people, when growing the bird of paradise, increase the frequency of fertilizing in order to speed up its growth, but this behavior is wrong. Although the bird of paradise likes fertilizer, during the growing season, applying an appropriate amount of nitrogen and phosphorus fertilizer helps its flower bud differentiation, and generally twice a week is enough. If the frequency is too high, it will cause root burn in the bird of paradise, resulting in the phenomenon of scorched, yellowing and curling leaves, so fertilizing must be done in the right amount, and unfermented fertilizer must not be applied; you must make sure the fertilizer is fully decomposed before applying it.

2. Excessive light

The bird of paradise likes to grow in a warm and humid environment. If in summer it is placed outdoors in direct sun for a long time, it will cause the water in the leaves to be lost, leading to water shortage in the plant, which in turn causes insufficient nutrient supply to the leaves, poor leaf growth, and the phenomenon of scorched, yellowing and curling leaves.

3. Improper watering

The bird of paradise is a perennial herbaceous plant with thick roots that can store a large amount of water, so when watering, you must master the principle of watering thoroughly once the soil is dry. During watering, if the potting soil is not watered thoroughly, the roots will not be able to absorb nutrients, and long-term water shortage will also affect root growth and development, thereby causing leaves to curl and become scorched and yellow.

4. Too high temperature

The bird of paradise likes to grow in a warm and humid environment and fears intense heat. Generally, the optimal suitable temperature is between 20-28 degrees. When the summer temperature is too high, above 30 degrees, it will cause water loss from the roots, and the chlorophyll in the leaves cannot carry out photosynthesis normally, so when the rhizome of the bird of paradise cannot get nutrient supply, it will lead to phenomena such as scorched, yellowing and curling leaves.

II. Treatments

The bird of paradise is a perennial succulent plant, and its roots store a large amount of water and nutrients, so it is best to choose soil with good water permeability, generally mixing mountain soil, sandy soil and manure soil in a 3:1:1 ratio. Moreover, the bird of paradise needs fertilizer and water during the growing season, and needs appropriate watering before flowering, keeping the potting soil moist is enough, and generally topdressing once every 15-20 days is enough; it is best to grow it in a half-shade, half-sun environment. The bird of paradise is suitable for growing at around 20-28 degrees, so in summer it needs appropriate shading treatment, and in winter it needs heating, and finally it should be placed indoors in a ventilated and airy spot, ensuring 5 hours of light per day, which is beneficial to its leaf growth and development and alleviates scorched, yellowing and curling leaves.
