Both complementary foods are added once in 2 weeks during the entire period. This is about a month and a half before flowering and then all the flowering time.
7. Top dressing
During flowering, the plant needs a larger amount of nutrients, so it would be advisable to fertilize the flower more than three times a month during the growing season.
For this, mineral mixtures for abundantly flowering plants are perfect. When Begonia Melanobullata does not bloom, it is enough to feed once a month.
Begonia Melanobullata should only be transplanted if the previous pot for the plant is too small and the roots have filled the entire space in the container. In this case, you should take a pot a few centimeters larger, put drainage on the bottom, and then fill the plant with suitable soil.
When transplanting Begonia Melanobullata, you need to be very careful with its roots because it is very easy to damage them, and the recovery process takes a long time.
a) Propagation by cuttings
This is the easiest and most efficient way. Cuttings with 3-4 leaf plates should be cut from an adult plant. To prevent rot from appearing on the cuts, it is recommended to treat them with charcoal. The resulting cuttings are planted in a mixture of leaf and peat soil and sand, equal proportions.
The container is placed in a well-lit and warm place. Water moderately and do not allow overflow. After about a month, we should expect the rooting of the cuttings. Then they can be planted in pots and grow a full-fledged bush of home begonia.
b) Propagation by leaves
When propagation by leaves, the entire leaf plate and its part is suitable. If the Begonia Melanobullata is propagated as a whole leaf, then the veins must be cut on the underside of the leaf.
Then the sheet plate should be laid with the notched side on the surface of moistened sand (sand for disinfection should be calcined in advance). Watering, in this case, occurs through the pallet because.
The sheet itself cannot be wetted in any way; otherwise, it will rot. After about eight weeks, roots will appear from the incised places.
c) Propagation by seeds
Although growing Begonia Melanobullata from seeds is considered unpopular, it is relatively simple and labor-intensive. When the flowering period is over, you should collect the seeds and save them until February or March.
During this period, sowing is carried out, evenly distributing the seeds over the soil’s surface. After that, the bed should be sprayed with water, covered with film or glass, and placed in a warm, well-lit place.
Seedlings should be sprayed daily with water or watered through a pan. When the first shoots appear, the shelter is removed, and after the formation of 3-4 true leaves, the sprouts should be picked in separate containers.
In two months, the sprouts will get stronger, and they can be transplanted into a permanent pot. With proper care and good lighting, the flowering of a crop grown from seeds begins in the first year.
Begonia Melanobullata is a slow-growing plant with ovate to round leaves from the Vietnam cliffs. Its leaves are green, covered in beautiful structures known as bullae. It does well in high humidity and bright, indirect light but require some airflow because it originated from the limestone cliffs.
