Growing tuberous begonia by dividing a tuber


Growing tuberous begonia based on dividing a tuber with several sprouts into parts, followed by germinating them in pots or boxes.

After the tubers are separated, the slices are sprinkled with crushed coal, dried and placed for germination. Reproduction and cultivation of tuberous begonias by dividing the tuber is usually practiced to rejuvenate old tubers, because old plants bloom much worse than young ones.

For targeted reproduction begonias by spring cuttings, large tubers are left alone in autumn for 3 months, planting for germination only in January. After the third leaf appears on the sprouts, cuttings with 2 leaves are cut from them with a razor and part of the sprout with 1 leaf is left.

After dusting the cuts with crushed coal, the cuttings are planted in the substrate according to the 5 by 5 cm scheme (a mixture of leaf, peat soil and sand in equal parts) and moistened well. When maintaining a temperature of 20 degrees, high humidity of the air, soil and shading from the sun, the cuttings take root within a month. Then you can plant them in individual pots.

In addition to the spring, there is also autumn cuttings: shortly before the digging of plants, in August, the shoots are separated from the tubers of adult begonias, planted in a substrate to a depth of about 4 cm, kept until spring, like houseplants, with moderate watering.

Since tuberous begonias have a dormant period in winter, most of the leaves (and sometimes the entire aboveground part) often die off in cuttings, although the compacted underground part remains. In the spring, cuttings are also planted in individual pots.
