Begonia sutherlandii is a perennial tuberous herbaceous plant, native to southern Africa; this species produces thin fleshy, translucent, light green, prostrate stems, which bear medium-sized cordiform leaves, light green in color, with irregular and serrated edges, slightly fleshy and waxy. Throughout the year it produces thin stems that carry yellow or orange flowers. They are grown in the apartment, in a container, often in hanging baskets; flowering is abundant, especially during the spring months; it is advisable to remove the stems that carry faded flowers, to prolong the flowering. They are plants of easy cultivation, they can also be used in the garden, in shaded flowerbeds, generally as annuals and to be grown with simplicity even by those who are beginners with gardening.
Like most tuberous begonias, they prefer semi-shady or shaded positions in order to grow optimally; they are grown in the apartment, although they can withstand temperatures close to zero or even very short frosts. If grown in the garden they lose the aerial part during the winter months; It is also possible to plant them in the garden in spring and unearth the tubers when the aerial part dries up, to keep them in a sheltered place until the following spring. As for watering, it is good to irrigate the begonia sutherlandii regularly, avoiding leaving the soil dry for long periods of time; water it abundantly, with regular frequency. Every 15-20 days add fertilizer for green plants to the water.
The soil is an element that should not be underestimated if you want to grow a plant in an optimal manner. The soil is in fact the main source of sustenance for the plants and it is good to choose it carefully to guarantee the best growing conditions for our cultivation. Begonia sutherlandii plants prefer fresh and soft, well-drained soils; avoid heavy or too compact soils. Pot cultivated specimens should be repotted every 2-3 years.
Reproducing plants always causes great satisfaction as it is an operation carried out with care and attention, with patience and expectations. Let's see how the begonia is reproduced.
The plant is multiplied by seed, in spring, or by division of the tubers, in autumn. In this second case, the largest tubers are chosen to allow those who wish to carry out this procedure to leave at least one shoot on each portion. The ideal temperature for reproduction should be around 20 degrees.
Begonia - Begonia sutherlandii: Pests and diseases
Begonia sutherlandii species can be attacked by aphids or cochineal. Aphids are also called plant lice and are particular types of insects that attack most ornamental plants. They have a tiny body (1-3 millimeters) and a mouth apparatus able to suck the sap contained in the plants and to perforate leaves, branches and shoots.
Just like aphids, cochineals are very small insects that cause discoloration and spotting of leaves, deformations and a slowdown in growth.
Another problem could concern the excesses of watering: in this case you will probably notice root rots.
