How to Grow Green King? A Full Breakdown of the Latest Growing Methods

Green King is a perennial herbaceous foliage plant of the genus Rohdea in the family Araceae. Its broad leaves attract many people's attention, and its elegant and beautiful leaf form means it is often placed on long tables in studies and halls or beneath long scrolls of calligraphy and painting. In autumn and winter, red berries add even more color, and it can also purify the air and absorb harmful gases. Now let us take a look at how to grow Green King!

Green King's Growth Habits

Green King is suited to a warm, humid, and semi-shaded environment. It grows vigorously in summer, so it needs to be placed in a shaded spot for growing to avoid strong light exposure; otherwise, the leaf tips are prone to drying and the edges to scorching, which affects the ornamental effect. After being moved outdoors in early spring, it should be placed under a shaded trellis or eaves or in a shaded spot on a balcony. Pay attention to moisture control; it should not be too dry or too wet. In summer, water should be sprinkled around Green King and on the ground every morning and evening to create a humid microclimate. After being brought indoors in winter, the room temperature must not be lower than 12°C. If the room temperature is too low, Green King is prone to chilling, leaf drop, and death.

Green King's Propagation Methods

1. Division: Green King can be propagated by division using the suckers at the base, generally carried out in spring together with repotting. During the operation, lift the plant out of the pot, cut apart the rhizome at the base of the stem, coat it with plant ash to prevent rot, or leave it for half a day until the cut surface dries and then pot it, and water thoroughly. After planting, do not water too much; growth can recover in about 10 days.

2. Cuttings: Green King is best propagated by cuttings during the high-temperature period from July to August. Cut 7-10 cm from the top of the stem, remove part of the leaves to reduce water evaporation, coat the cut with plant ash or sulfur powder, insert it into a sand bed, or wrap the cut with sphagnum moss, maintain relatively high air humidity, and place it in a semi-shaded spot with about 50-60% sunlight. At a room temperature of 24-30°C, roots form 15-25 days after insertion. After new buds sprout on the stem section, transplant it into a pot.

Green King's Growing Methods

1. Soil: Growing Green King requires loose, fertile, well-drained soil. Peat can also be used to prepare the soil. Add water to the peat and mix well (after mixing with water, when you tightly squeeze a handful of peat, water seeps out between your fingers), then plant it in cups. A 12 cm pot uses about 350 ml of peat per pot; one 300-liter bag of peat can fill about 800 cups.

2. Repotting: For old pots reused for Green King, they must be soaked in a 1000-fold potassium permanganate solution for more than half an hour, then rinsed with clean water and dried for later use. Small potted plants are generally grown in pots with a diameter of 12 cm. When planting, first place about 2 cm of substrate at the bottom of the cup, then move Green King into the cup. Small seedlings should not be planted too deep; it is best to keep them level with the base of the plant. The substrate should be moderately firm, and the cup should be filled to 9/10 full, with 3 plants per pot.

3. Light: Green King tolerates semi-shade and avoids overly strong sunlight; otherwise, it easily causes dry leaf tips and scorched edges, affecting the ornamental effect. However, too little light can also cause Green King's leaves to fade.

4. Temperature: Green King likes high temperatures and is not cold-tolerant. The suitable growing temperature is 20-30°C, the dormancy temperature is 13°C, and the minimum overwintering temperature is above 12°C. Once frozen, Green King's leaves turn yellow and wilt, and the terminal buds die.

5. Water: Green King likes moisture and tolerates drought. Watering should follow the principle of watering when dry; generally water once every 3 days, keeping the soil slightly moist, and the specific timing should be judged according to the local air humidity. During the growing period from March to August, water more; in summer, sprinkle water frequently to increase environmental humidity.

6. Fertilizing: During Green King's growing period, apply nitrogen fertilizer every month to promote rapid growth. Apply compound fertilizer about once every 20 days. From March to August, apply fertilizer water once every two weeks, and reduce fertilizing after autumn. Repot once a year and apply base fertilizer, and apply a dilute liquid fertilizer once a month to promote leaf growth, deepen leaf color, and maintain the best ornamental condition.

7. Pests and diseases: Green King is most susceptible to leaf spot disease. This disease occurs on Green King's leaves. The lesions initially appear as small brown spots, with a water-soaked, faded green margin, and expand in concentric rings, round to oval, with brown edges and grayish-white centers. Later, dark brown mold spots appear in the center of the lesions, and under humid conditions they become a dark brown mold layer. The method to prevent and control this disease is to promptly remove diseased and dead Green King leaves. Both in the early and late stages of the disease, a 0.5-1% Bordeaux mixture (or a 50% carbendazim 1000-fold solution) can be sprayed.

Precautions for Growing Green King

1. Green King is a fleshy-root plant, and water accumulation easily leads to waterlogging; too much watering easily causes Green King's roots to rot. However, the air must remain humid; if the air is dry, undesirable phenomena such as dry leaf tips on Green King are also likely to occur.

2. In summer, increasing water spraying on Green King's leaf surface has multiple effects, such as washing off dust, lowering temperature, preventing sunscald, and increasing air humidity.

3. When growing Green King, care should be taken to prevent heavy rain from drenching it, especially during the flowering period when it must not be exposed to rain. It should be placed in a shaded, dry, ventilated place away from rain.

4. To make Green King grow dignified and symmetrical, the placement angle should be adjusted every half a year.
