How to Plant Gloxinia Tubers? A Detailed Guide to the Planting Method

Gloxinia is a very brightly colored ornamental flower, and quite a few people grow it, so how do you plant gloxinia tubers?

1. Basic Introduction to Gloxinia

Gloxinia is a perennial herbaceous plant of the Gesneriaceae family and the genus Sinningia, with colors including pink, red, purple-blue, white, and bi-color, blooming from March to August each year.

Gloxinia prefers a warm, humid, semi-shaded growing environment. It blooms twice a year, in spring and autumn, and is an ideal flower for holiday decoration and indoor display.

The suitable temperature during the growing period is 20-25°C. When the winter temperature drops to around 5°C, it goes dormant. Excessively high temperatures also affect normal plant growth; when the summer temperature rises above 30°C, the plant enters a semi-dormant state.

2. How Do You Plant Gloxinia Tubers?

First, bury the tuber in prepared soil. Water the gloxinia thoroughly. When the sprouts grow to about 0.5 cm, dig out the tuber and cut it into 2-4 pieces, each piece needing to have a sprout, then transplant them into other pots. After transplanting, place them in a spot with scattered light to grow, and water and fertilize according to the gloxinia's growth conditions.

The flowers and leaves of gloxinia are covered with fine hairs, and once they get water droplets on them, they rot very easily, so do not spray water on the flowers and leaves. It is best to water using the immersion method. Normally, water in moderation; too much can easily cause tuber rot, yellowing leaves, and even the death of the entire gloxinia plant. During the high-temperature period in summer, water 1-2 times a day, and when the air is dry, frequently spray water around the plant to increase the environmental humidity. Watering should be even, neither too dry nor too wet. During the flowering period, rain must be avoided. In winter, the potting soil should be kept a bit drier.

Gloxinia prefers loose, fertile humus soil with good water retention. It is best cultivated in humus-rich, loose, slightly acidic soil. A common mix is 1 part perlite, 1 part river sand, and 3 parts leaf mold, plus a small amount of decomposed, sun-dried, finely crushed poultry manure. From leaf unfolding to before flowering, apply a dilute decomposed organic liquid fertilizer once a week; after flower buds form, additional phosphorus fertilizer is needed. When fertilizing, never let it contaminate the leaf surface. After each fertilization, spray clean water once and keep the leaf surface clean. Also note that after watering, water droplets should not remain on the leaves for a long time, otherwise the leaves will rot.
