When does the海棠花 (海棠花) bloom?
The editor will tell you about when the海棠花 blooms and some knowledge about the best viewing season for海棠花. Let's follow the editor and see the specific content!
海棠 generally blooms between March and October every year and can bloom 3-4 times a year. The specific blooming time of the plant is related to the sowing season, usually taking about 145-160 days from sowing to blooming. The flowers open at the top of the branches, mostly in red and pink colors, and the flower shape is small.
In order to make the海棠 bloom quickly, it needs to be provided with more than 6 hours of sunlight every day during the growing period to accumulate nutrients for blooming. It is recommended to place the pot in an outdoor sunny area, avoiding direct sunlight at noon, and spray potassium dihydrogen phosphate 2-3 times a month before the blooming period.
After the海棠 blooms, it is necessary to promptly cut off the withered flowers and branches attacked by diseases and pests, and then thin out some of the dense and long branches to improve internal ventilation and maintain the beauty of the plant. Moreover, the blooming period of海棠 consumes a lot of nutrients, so compound fertilizer should be supplemented immediately after blooming.

Methods to promote海棠 blooming
1. Watering and fertilizing
Watering should keep the potting soil moist. In dry and hot weather, it is necessary to spray water on the leaves and the ground to increase humidity, which is beneficial to growth. Avoid waterlogging and rain, as it can easily cause root rot. In winter, the potting soil should be slightly dry, and the leaves and environment should be sprayed with water every 7 days, which not only increases humidity but also keeps the leaves clean. During the growing period, apply a dilute cake fertilizer once every 10 days; during the bud formation period, apply a fast-acting phosphorus fertilizer. When fertilizing, be careful not to splash fertilizer on the leaves; do not fertilize during the blooming period and in winter and summer.
2. Light and temperature
The optimal temperature for the growth of bamboo-stemmed海棠 is between 18-20°C, with good ventilation and scattered light. Measures such as shading, ventilation, and spraying water are needed during the high-temperature season. It is better to maintain the room temperature above 10°C in winter and place it in a sunny area. When growing at home, it should be placed in a scattered light outdoors 1-2 times a week during the growing season and in a sunny and sheltered place in winter.
3. Tying and potting
As the bamboo-stemmed海棠 plant is tall, it is necessary to set up stakes to support the branches to prevent them from falling over. At the same time, every spring, you need to change pots, change soil, and prune, cutting off weak branches, overlapping branches, and residual roots. For plants that have bloomed for 2-3 years and are too tall, shortening should be implemented, leaving only 6-10 centimeters of the stem to allow new branches to grow.
