Spring swords are unearthed from early May to early June every year, and autumn buds are unearthed in the middle and late August. There is a slow period of about 20 days after the new leaf buds are unearthed, from the end of May to the end of June, from June to 10, and the dormant period is 1 1 to February of the following year. It takes about 1 year for each spring sword seedling to grow.
The suitable growth temperature of spring sword is 18 ~ 28℃, not more than 35℃ in summer, not less than -2℃ in winter, and the reproductive growth temperature is 8 ~ 18℃.
Spring sword's requirements for air humidity: 55% ~ 70%, the air humidity in winter dormancy period (the driest air exercise) should not be lower than 50%, and the best air humidity in growth period should be kept at about 70%.
Spring sword's requirements for water: Spring sword likes to be cool, the soil in the basin should not be too wet, and more water should be watered during flowering and growth period, and less water should be watered during dormancy period. Spring sword should be cultivated in a deep-barrel plain-fired pottery jar. Its pseudo-scales are clustered and oval, with strong roots. Both pseudo-scales and thick roots have certain water retention, which can cope with short-term drought for about 6 days.
Requirements of spring sword on light: The light condition suitable for the growth of spring sword is semi-cloudy, and the shade is required to be about 65% ~ 75% in summer and autumn, and the light can be appropriately increased in winter and spring.
Spring sword and cymbidium have similar habits, can resist cold, and can survive the winter smoothly at room temperature; In winter, we should also fully irradiate the sun to make the flower buds full and strong.
Spring sword should be cultivated in spring and replanted after flowering. If it is grass, you can plant it before it blooms in spring, and you can see the flowers soon.
