How to cultivate Canna seeds
This article provides an overview of how to grow Canna seeds and related introductions to the cultivation and management of green plants and flowers. Next, the editor will introduce to the netizens.
Canna is a perennial herbaceous plant that can grow up to 1.5 meters tall, with the whole plant being green and hairless, covered with waxy white powder. It has block-like rhizomes. The aerial shoots are tufted. The leaves are alternate, with a sheath-like petiole; the leaf blades are ovate-oblong. The raceme inflorescence has solitary or opposite flowers; there are 3 sepals, greenish-white with red tips; the corolla is mostly red, with 2-3 outer退化 stamens that are bright red; the labellum is lanceolate and curved; the capsule fruit is oblong, green, and flowers and fruit from March to December.
I. Light
During the growing period, it requires sufficient light and should receive at least 5 hours of direct sunlight every day. Insufficient light in a dark environment will delay the blooming period. It prefers warmth and dislikes severe cold. To extend the blooming period, it can be placed in a place with low temperature and no sunlight during flowering, and the ambient temperature should not be lower than 10℃.
II. Temperature
The environmental temperature should be around 30℃ during the day and 15℃ at night. After 10 days, the seeds will germinate. After germination, plant the rhizome with 2-3 buds in a pot, keep the soil moist, and fertilize appropriately. Flower buds appear in early April, and flowers can bloom by Labor Day with proper ventilation.
III. Fertilization
Proper fertilization is a key measure for maintaining Cannas. Whether grown in a pot or in the ground, sufficient base fertilizer should be applied before planting, with the base fertilizer mainly consisting of compost, and an appropriate amount of soybean cake, bone meal, or superphosphate should be added. During the growing period and before flowering, liquid fertilizer should be applied every 20 days or so, and during the peak growing season, 3-4 times of thin cake liquid fertilizer should be top-dressed each month. If no flower scape has emerged 20-30 days before the expected flowering period, a 0.2% potassium dihydrogen phosphate solution can be sprayed on the leaves to promote flowering.

IV. Watering
Before new roots grow after planting, water sparingly. The potting soil should be moist but not too wet, as excessive moisture can cause root rot. After the flower scape has emerged, water frequently to keep the soil moist. If water is insufficient, "flowers in the leaves" may appear after flowering. In winter, reduce watering, following the principle of "keeping dry and wet."
V. Cultivation
Plant in early to mid-April (Zhengzhou area). For ground planting, use hole planting, with each hole containing 2-3 buds, spaced 80cm apart and about 20cm deep. After planting, cover with 10cm of soil. For pot planting, choose shorter varieties, leaving 3 buds per pot. After planting, cover with 8-10cm of soil.
VI. Pest and Disease Control
Leaf mosaic disease; when propagating, choose virus-free and vigorous rhizome materials, and control the vector of the disease, aphids, throughout the growing period. Banana shoot borer; promptly remove leaf sheaths and kill larvae; before the larvae form leaf sheaths, use a 90% carbaryl solution diluted 1000 times to kill the larvae, or spray with 1000 times dilution of Itabac at dawn or dusk.
