A Detailed Guide to the Cultivation and Care of Thalia dealbata (Powdery Alligator-flag)
Thalia dealbata (Powdery Alligator-flag)
Scientific name: Thalia dealbata
Aliases: water arrowroot, water lotus banana, Thalia.
Family and genus: Marantaceae, genus Thalia
Morphological characteristics: perennial emergent herb, plant height 2 m. The whole plant is covered with a white powder; leaves ovate-lanceolate, light grayish blue, with purple margins, 50 cm long and 25 cm wide. The petioles are extremely long. Compound raceme, flowers small, violet. The bracts look like flying birds.
Ecological habits: grows well in slightly alkaline soil. It likes a warm, humid and sunny climate; not cold-tolerant, tolerates partial shade, fears drought. The optimum growth temperature is 20-30 degrees C; growth stops below 10 degrees C. In winter the temperature must not fall below 0 degrees C; it can withstand short periods of -5 degrees C. After winter sets in, the above-ground parts gradually die back, and it overwinters as rhizomes in the mud.
Propagation method: propagated by rhizome division. In early spring, cut rhizomes with 1-2 buds from the mother plant, plant them in a tray, apply sufficient basal fertilizer before planting, preferably peanut bran and bone meal, place them in a water pool for care, and once new plants have grown, transplant them into the pool to grow.
Cultivation and care: when grown indoors, keep the soil moist during the growing season, spray the leaves with water frequently, and fertilize once a month. When planted in the open, provide appropriate shade during high summer temperatures and strong light (however, the author has seen plantings in Wuhan without shade). Prune out excessively tall growing branches and damaged leaves, and thin out overly dense clumps appropriately to improve ventilation and light penetration. Generally divide the plants once every 2-3 years.
Flowering period: summer and autumn.
Flower meaning: fresh and lovely.
Landscape uses: the plant form is beautiful and graceful, and the purple flowers are interesting. For waterscape greening, as a background in wetland landscapes, and for potted ornamental display.
Species identification: both its plant form and leaf shape resemble those of the water canna; Thalia dealbata grows in clumps and has extremely long petioles, whereas the canna has upright stems and very short petioles.
(1) Temperature and environment: Calathea makoyana is native to Brazil and likes a warm, humid, semi-shaded environment; it fears low temperatures and dry winds, has poor resistance to low temperatures, and dislikes direct sun exposure, so in summer it should be grown under a shade frame. When the temperature is above 30 degrees C, the leaf margins scorch, new shoots sprout less, and the leaves turn yellow; water should be sprayed frequently to maintain moisture and lower the temperature. In winter it should be given plenty of sunlight.
(2) Soil: Calathea makoyana likes well-drained, fertile, loose, slightly acidic leaf mold or potting soil. For the growing medium, a small amount of decomposed basal fertilizer can be added, and leaf mold, peat soil and river sand mixed in equal parts to make potting soil.
(3) Water and fertilizer: Calathea makoyana likes a humid environment and should be given plenty of water during the growing season. If it goes dormant at low temperatures in winter, watering should be controlled, keeping the potting soil merely from drying out, and after new leaves emerge the following spring, watering can gradually return to normal. During the growing season, apply a liquid fertilizer once a month to supply the nutrients needed as old leaves are replaced by new ones, and to promote vigorous plants and vivid leaf color. When fertilizer is lacking, the plant becomes noticeably smaller, the leaves turn pale yellow, and the metallic sheen loses its brightness. Fertilizer should be based mainly on phosphorus and potassium, and nitrogen should not be excessive. Generally, use a 0.2% liquid fertilizer sprayed directly on the leaves, then rinse with a small amount of water to prevent fertilizer burn; phosphorus and potassium fertilizer is also very beneficial for the sprouting and growth of new shoots. Fertilization should stop in winter.
(4) Pest and disease control: Calathea makoyana has relatively few pests and diseases, but under dry air and poor ventilation it is prone to scale insects and whiteflies, which can be killed by spraying with a 1000-fold dilution of 25% phosmet emulsifiable concentrate or a 1500-fold dilution of 40% omethoate.
