Can Gloxinia tubers be cut and propagated in winter?

Gloxinia is one of my favorite potted flowers. The blooms are truly vivid, with rich colors, and it can bloom twice a year. As for gloxinia propagation, the common methods are seed propagation, cutting propagation and tuber propagation. Gloxinia's peak growing season is in spring and autumn, so it mainly blooms in spring and autumn as well.

In the high-temperature summer and the low-temperature winter, gloxinia goes dormant. Gloxinia likes a warm, humid, bright-indirect-light environment and fears high temperatures and direct scorching sun. After the temperature rises above 30 degrees, it will slowly enter dormancy, so summer is mainly a period of dormancy. Winter is severely cold and gloxinia is afraid of the cold. When the temperature drops below 5 degrees, insulation measures must be taken. If it stays below 5 degrees for too long, it will suffer cold damage.

If the timing for cutting the tuber is wrong, it is all in vain

As for the question netizens care about, gloxinia can indeed be propagated by tubers, so after autumn begins, it is also the time when many enthusiasts frantically hunt for tubers. After winter begins, the upper leaves slowly wither and then it enters dormancy, so gloxinia is not recommended for propagation in winter, unless it is in a greenhouse environment, where a temperature of around 15 degrees is needed for safe propagation.

Gloxinia tuber propagation can be done by directly burying the tuber in potting soil to propagate, or by cutting the tuber to propagate. Just like when we plant potatoes, we can directly cut potatoes into pieces to propagate, and gloxinia is the same; the tuber can also be directly cut open to propagate. However, in winter it is not recommended to cut the tuber open; instead, let it spend the winter safely. It is recommended to take the gloxinia corm out of the pot, dig it out, and store it in a cool, dry place to overwinter.

In early spring, when all things revive, after seeing buds sprout on the trees outdoors, choose a gloxinia corm that has already grown for 3 to 4 years, then cut it into four pieces, cutting straight down the middle. It should be emphasized here that tubers at least 3 years old have a higher survival rate when cut open. If it is a 1- or 2-year-old tuber, the tuber is too tender, and once cut open it is not easy to get it to take, so simply bury the whole intact tuber into the potting soil.

For a cut tuber, bury it directly in the potting soil, do not water it thoroughly, and place it directly in a cool, ventilated, bright-indirect-light spot for care. After 20 days, you will see the tuber begin to grow roots, and then just spray water to maintain moisture for care.
