We could include the begonia tuberose among the bulb plants that bloom in summer, although their beautiful flowers can appear at any season of the year depending on the weather. The peculiarity of the begonia is that it blooms it prefers to be in the shade, so it is a species indicated for those less sunny corners of the garden where it is difficult to find flowering plants.
The genus Begonia is composed of hundreds of species of tropical plants, but tuberose is not exactly one of them. It is actually a hybrid created by growers who were given the botanical name Begonia x tube hybrid. It is a perennial herbaceous plant that grows from a crushed tuber. The stems and leaves have a hairy surface covered by fine and soft hair. The foliage is bright green and very attractive. The flowers are big.
Begonia tubers must be planted in late winter or early spring. The soil must be somewhat warm so that the plant can sprout and generate new stems.
Begonias are not resistant to direct sunstroke, the sun’s rays cause burns on their leaves. The best place for them is a shaded area, even inside the house in front of a window that provides good lighting. It is a plant suitable for shady gardens.
They should not be irrigated in excess, the roots of the begonia do not tolerate waterlogging. However, they are plants that require a humid environment. This can be achieved by placing them next to other major plants that protect them and create a humid atmosphere around them.
In autumn, irrigation can be reduced and even suspended in winter.
Begonias are very sensitive to cold and can die if frosts occur. In cold climates, they can lose their aerial part. In this case, the irrigation should be reduced at the end of the flowering season and suspended when the leaves turn yellow. The tubers can be removed to protect them from frost and store until the next season.
Like any bulbous plant, the best way to reproduce a begonia is to divide the bulbs that have buds, leaving at least one in each new piece. Before planting, let the cut heal.
Plagues and diseases
At Aphids are attracted to new outbreaks of begonias and thrips love to set them on the undersides of their leaves tender. The best way to prevent the attack of these insects is to check the plants from time to time and act at the slightest hint. The most effective natural treatments are to apply potash soap dissolved in water spray or clean with a brush dipped in alcohol.
In addition to preventing the attack of insects that impair their appearance and health, begonias need little attention to look good. The branches full of flowers should be numbered so that the stems do not break by weight. It is also advisable to eliminate withered flowers and dried, diseased or damaged leaves.
