Ecological habits of Gloxinias

Gloxinias (Sinningia speciosa) prefer warm and humid growth periods and avoid direct sunlight. It has a certain anti-heat ability, but it should be kept cool in summer. It is favorable for flowering at around 23℃, tubers in the temperature of 5℃ or so, can also be safe over the winter.Growth period requires high air humidity, do not like water, to avoid rain invasion; Winter dormant period should be kept dry, such as humidity is too large or the temperature is too low, the tuber is easy to rot. Gloxinias like fertile loose micro acid soil.

Wild in the tropical highlands where summers are cool and winters are warm. Gloxinias prefer warm, humid and semi-cloudy conditions during growth. High temperature and humidity in summer, unfavorable to plant growth, need appropriate shade. The growing period requires high air humidity, and the leaves grow luxuriant and green. Winter dormant periods to stay dry, such as humidity is too large, the temperature is low, the tuber is easy to rot. The temperature in winter is not lower than 5℃. Gloxinias require fertile, loose and well drained humus - rich soil.

The origin of Gloxinias

Originally from Brazil, gloxinias (Sinningia speciosa) was discovered in Brazil, South America, in 1785 and introduced to Europe in the early 19th century.

In the 1990s, dwarf and miniature Gloxinias were bred, which opened up a new way for potted appreciation of Gloxinias.

In China, Gloxinias (Sinningia speciosa) was introduced mainly from the United States in the 1930s by the College of Agriculture of Jinling University and the Zhongshan Cemetery Memorial Botanical Garden in Nanjing. After the founding of new China, botanical gardens around the formal introduction of trial species. It wasn't produced in small quantities until the 1990s, and it hasn't taken off yet.

Summer high temperature stage, watering 1 ~ 2 times a day. When the air is dry, spray water around the plant often to increase the humidity of the environment. Watering should be uniform, not dry wet, sometimes hot and sometimes cold. Rain must be avoided during flowering. The pot soil should be drier in winter.

Four, fertilization. Gloxinias (Sinningia speciosa) prefers loose, fertile humus soils that retain water well. Gloxinias is suitable for rich humus, loose and slightly acidic soil cultivation. Commonly used 1 perlite, 1 river sand and 3 leaves of soil plus a small amount of decayed, dried finely fowl excrement preparation. From the opening of the leaves to before flowering, apply a thin organic fertilizer once a week, after the formation of flower buds you need to add phosphate fertilizer. Do not stain the leaf surface when applying fertilizer. After each fertilization, to spray water 1 time, keep the leaf of Gloxinias clean. Water droplets should not stay in the leaves for a long time, otherwise the leaves will rot.
