Aspidistra Blooming Time, Yellowing Leaf Treatment, Growing Methods and Precautions
Aspidistra, also known as cast-iron plant, with the aliases large-leaf evergreen, bamboo-leaf tray, nine-dragon tray, bamboo-joint sinew-stretcher, etc., is a plant of the Liliaceae family, genus Aspidistra. In traditional Chinese medicine, the rhizome components are used medicinally, and it is a very widely applied medicinal material. So when does Aspidistra bloom? What should be done when the leaves turn yellow? Now we have compiled the growing methods and precautions for Aspidistra for everyone.
When Aspidistra blooms
Aspidistra blooms between March and April (under natural conditions). However, if grown at home, the temperature changes through the four seasons differ from nature, and when temperatures are higher than those of the same period, it generally blooms earlier. Still, Aspidistra grown at home rarely blooms, and this is also related to the environment, so it cannot be forced.
The flower language of Aspidistra
The flower language of Aspidistra is everlasting love and one of a kind, so Aspidistra is often used as one of the gifts exchanged between lovers. Because they hope to become each other's one and only, and everlasting love is also the best blessing for couples.
Cultivated varieties of Aspidistra
1. Spotted-leaf Aspidistra: Spotted-leaf Aspidistra, also known as sprinkled-gold cast-iron plant, spotted-leaf cast-iron plant, star-spotted cast-iron plant, is a cultivated variety of Aspidistra, with milky white or pale yellow spots on the green leaf surface.
2. Golden-line Aspidistra: Golden-line Aspidistra, also known as golden-vein cast-iron plant, white-vein cast-iron plant, is a cultivated variety of Aspidistra, with pale yellow longitudinal line stripes on the green leaf surface.
Division propagation of Aspidistra
1. Division time: Division propagation of Aspidistra can be carried out in spring when temperatures rise and before new buds have sprouted, combined with repotting. It is generally done in early spring (February and March) after the soil thaws.
2. Division method: Take the mother plant out of the flower pot, shake off excess potting soil, separate the tangled root system as much as possible, and cut it apart with a sharp knife into two or more plants. Each divided plant must carry a considerable root system, and its leaves should be properly pruned so that each clump carries 3 to 5 leaves, to help it survive.
Growing methods for Aspidistra
1. Potting: Soak the divided small plants in a 1500-fold solution of chlorothalonil for five minutes, then take them out and let them dry, and they can be potted. Alternatively, immediately after potting, drench the roots with chlorothalonil.
2. Management: After the divided plants are potted, drench the roots or water thoroughly once. Because the root system has been greatly damaged and its water-absorbing capacity is extremely weak, it takes about 3 to 4 weeks to recover and sprout new roots. Therefore, within 3 to 4 weeks after division, watering must be restrained to avoid root rot. However, the transpiration of its leaves is not affected, so to maintain the water balance of the leaves, the leaf surface needs to be misted 1 to 3 times a day. Do not apply fertilizer during this period either. After division, also be careful of overly strong sunlight; it is best to place it in a shade shed for care.
3. Potting up: First place a 2 to 3 cm thick layer of coarse substrate at the bottom of the pot as a drainage layer, then place the plant in. The substrate used for potting can be one of the following: peat: perlite: ceramsite = 2:2:1, or peat: vermiculite = 1:1, or peat: cinder: ceramsite = 2:2:1, or sawdust: vermiculite: medium-coarse river sand = 2:2:1, or vegetable garden soil: cinder = 3:1, or garden soil: medium-coarse river sand: sawdust = 4:1:2, or paddy soil, pond mud, leaf mold, etc. After potting, water thoroughly once and place it in a shaded environment for care.
Maintenance techniques for Aspidistra
1. Soil: Aspidistra is not strict about soil and tolerates poor soil, but loose, fertile, slightly acidic sandy loam is best. For pot cultivation, equal parts leaf mold, peat soil and garden soil can be mixed as the substrate.
2. Water: During the growing season, Aspidistra should be watered sufficiently, keeping the potting soil consistently moist, and the leaf surface should be misted frequently to increase humidity, so as to favor budding and the growth of new leaves. After late autumn, the amount of watering can be appropriately reduced.
3. Light: Aspidistra can be grown year-round in a bright indoor space, but whether indoors or outdoors, it must not be placed in direct sunlight. Even a short period of direct sun exposure may scorch the leaves and reduce its ornamental value.
Summary: The growing methods for Aspidistra are introduced here for now. In fact, Aspidistra is very suitable for arrangement and placement in homes and offices. It can be enjoyed on its own or arranged together with other flowering plants, and it is also a foliage material for modern flower arranging. Friends who are interested can continue to look at the precautions for growing Aspidistra!
Precautions for growing Aspidistra
1. During the growing season, Aspidistra should be watered sufficiently, keeping the potting soil consistently moist, and the leaf surface should be misted frequently to increase humidity, so as to favor budding and the growth of new leaves. After late autumn, the amount of watering can be appropriately reduced.
2. When growing Aspidistra, besides paying attention to controlling temperature and moisture, special attention should also be paid to whether the Aspidistra is diseased. Diseased leaves should be promptly cut off and burned to reduce sources of infection.
3. Before the rainy season arrives, Aspidistra should be sprayed with a 1000-fold solution of 50% Shibaike or Shibaogong wettable powder, or a 500-fold solution of 25% Tanteling wettable powder. Once every 10 days, for 3 to 4 treatments.
4. Aspidistra is a shade-tolerant plant, and the light should not be too strong, otherwise it will cause leaf yellowing or disease. Overwatering, especially in winter, will cause root rot and will also lead to leaf yellowing.
5. When caring for Aspidistra in a greenhouse or shed, measures can be taken to raise the nighttime temperature of the shed, increase ventilation time during the day, and reduce the humidity inside the shed and the duration of fog formation, thereby achieving disease control.
6. During the vigorous growth period in spring and summer, Aspidistra should be given liquid fertilizer 1 to 2 times a month to ensure the leaves remain clear and bright. It can be grown year-round in a bright indoor space, but whether indoors or outdoors, it must not be placed in direct sunlight.
Reason one for Aspidistra leaves turning yellow: excessive light
Aspidistra has broad leaves, and its verdant leaves give people a feeling of warmth at all times. This plant is most afraid of strong direct light; even a short period of sun exposure will scorch the leaves and affect its ornamental value. If the green leaves in your home, after being baptized by the midday sun, turn into a pile of withered grass, you would be angry enough to die, or at least the plant would wither to death!
Solution: Aspidistra can be kept year-round in a bright indoor space for cultivation, but it should not be placed where sunlight shines directly, especially beside a window. There is no need to deliberately put it in the sun.
Reason two for Aspidistra leaves turning yellow: too little light
Plants are sometimes very strange, and it is hard to guess what they are thinking. They cannot take sun exposure, but shade is not good either. Although Aspidistra is very shade-tolerant and can grow for several months in a dark environment, long-term darkness is not conducive to the budding and growth of new leaves. The newly grown leaves are dull and lusterless. Although they will not turn into withered leaves, their appearance is not very beautiful either.
Solution: Aspidistra can be placed in a dark environment, but it is best to move it to a bright environment every so often so it can feel the warmth of the sunlight, which is more conducive to growth and ornamental value. Especially during the period from the growth of new leaves to maturity, keep it in a bright place for care as much as possible.
Reasons for Aspidistra leaves turning yellow
Too little light
Aspidistra has broad leaves, and its verdant leaves give people a feeling of warmth at all times. This plant is most afraid of strong direct light; even a short period of sun exposure will scorch the leaves and affect its ornamental value. If the green leaves in your home, after being baptized by the midday sun, turn into a pile of withered grass, you would be angry enough to die, or at least the plant would wither to death!
Solution: Aspidistra can be kept year-round in a bright indoor space for cultivation, but it should not be placed where sunlight shines directly, especially beside a window. There is no need to deliberately put it in the sun.
Overwatering
Overwatering is also one of the reasons for Aspidistra leaves turning yellow. Aspidistra likes water, but there is a certain limit. It will not wither and die even after several days of drought, but overwatering will affect root respiration, thereby causing the leaves to turn yellow. It is like a person who cannot swim suddenly being thrown into the water; after coming out, they will certainly be wilted!
Solution: Water Aspidistra by the principle of watering when dry and stopping when wet; do not water too much, but do not water too little either. During the growing period it needs sufficient water, but it must be ensured that there is no water accumulation.
Overly concentrated fertilizer
Aspidistra does not have a particularly large demand for fertilizer. It is best to use light fertilizer. Too much fertilizer can easily burn the roots, damaging the growth of Aspidistra, and the leaves will also turn yellow due to fertilizer damage.
Solution: Fertilization should not be too frequent. Apply a thin liquid fertilizer once every 15 days to promote the budding and growth of branches and leaves and ensure the leaves remain clear and bright. Absolutely do not apply too much fertilizer.
Pest infestation
Aspidistra cared for indoors is very prone to red spider mites. Red spider mites parasitize the leaves, and sucking sap will cause the leaves to turn yellow.
Solution: Frequently check both sides of the leaves, and frequently wipe the leaves with clean water to keep them clean and glossy. Once red spider mites are found, promptly spray dicofol, hexythiazox, etc. for control.
