Wax begonia prefers local shadows and indirect sunlight.
How to take care of the tuberous begonia's bulb in winter?
If the ground in the planting area freezes in winter, the bulbs need to be dug up after frost or when large amounts of leaves fall. Cut off the withered leaves, remove the rotten locals, and leave it in a warm and dry environment for days to dry the tubers. Place the dried tubers in a paper bag, store in a cool and dry place, and keep them indoors for winter.
When and how to repot wax begonia?
If wax begonia stops growing under normal conditions of fertilization and water supply, only a few flowers will bloom during the flowering period. This circumstance may indicate that the flowerpot is too small to grow it and a larger container is required. If the basin soil doesn't dry easily, this means the container may be too large. Potted wax begonia is usually repotted in the early spring of each year. Pat the flowerpots gently to remove the plants and soil blocks. Trim off old and rotten roots, change media, and apply thin base fertilizer. The outer perimeter of the new planting container should be 2 inches larger than the begonia root.
Why does my wax begonia only grow long leaves without flowering?
①Lack of light. Wax begonia is sensitive to light and can undergo flower bud differentiation and blossom under long-term scattered light. Lack of light makes it difficult to form flower buds.
②Excessive fertilization. Applying too much fertilizer (especially nitrogen fertilizer) makes it conducive to strong vegetative plant growth with dense branches and leaves and no flowers. For begonias, thin fertilizer should be applied frequently with balanced nutrition, and more phosphate fertilizer should be applied in the flowering season (gardening stores will sell compound liquid fertilizer for the flowering season and vegetative growth period).
③Overwatering. Overwatering leads to excessive growth and is accompanied by a risk of root rot.
In addition, frequently cut off plants according to their state, trim off the terminal buds and overgrown and over-dense branches to promote the growth of the remaining lateral branches, and shape full plants.
