2. Choose a location. Begonia is a common flower, which can be successfully planted indoors and outdoors. They like shade, so they are very suitable for indoor potted plants. If you want to plant begonia in a flowerpot, you should choose a place in the window facing east, west and south in the house, or you can put it in a cool and dimly lit corridor. If you plan to plant them in the garden, plant them on a shady clod under a big tree or on the north side of the garden.
3. Prepare the soil. It is better to say "no soil preparation" than "no soil preparation", because begonia grows better in the mixed soil of the garden than in the specific soil. Prepare a mixture of 2/3 peat soil and 1/3 free potted soil (available in gardening stores and nurseries). Begonia likes the acidic environment with good drainage provided by peat soil. If you must use other soil, mix peat soil and organic matter in the soil to provide the best environment for your begonia.
4. Know when to sow. Begonia is an annual plant, so it can't grow back the next year. Therefore, it is necessary to replant every year, usually when spring is strong. Begonia can't stand low temperature and frost, so plant it at least one week after the last frost in winter. If there is no other way, plant it in indoor pots at an early stage and transplant it when the weather gets warmer.
Planting steps 1. Prepare a garden or container. If you plan to plant begonia outside, dig a hole about 10 cm deep and bury the seeds and stems, as long as it can cover the root pile of potted plants. Begonia should be placed in flower beds or flowerpots, in containers slightly larger than the roots, or mixed with other potted plants in larger containers. Begonia doesn't need much space. You can plant them with other plants in your garden, in a flowerpot or beside the bed at will.
2. plant begonia. Place stems, seeds or transplanted plants in the holes you dig. Each begonia should be planted in a separate hole, but these holes can be close together. Cover roots, stems or seeds with soil or potted mixed soil more than ten centimeters deep. If you plan to plant a small begonia, break the roots into small pieces and bury them in the pit.
3. Water the plants. Most plants need extra water after planting to avoid the so-called "transplant shock". Water your begonia more to keep the soil moist.
4. Maintain the garden. If you plant begonia on the porch or in an indoor flowerpot, you don't need to deal with weeds. However, if you plant begonia in an outdoor garden, check the weeds and clean them up every few days. Apply 20-20-20 liquid fertilizer once a month, or mix some compost and peat soil to increase nutrition.
5. Pick the dead flowers of begonia. Over time, you will find that the flowers of Begonia begin to turn yellow and then die. At this time, it is necessary to pick the dead flowers of begonia, that is, cut or pull out the dead flowers to promote the growth of new flowers and transfer nutrients to other parts of the plant. At the end of the flowering period, the dead buds are picked, leaving green plants.
Begonia can be planted from seeds, but it takes about 4 months to break ground. Seeds are very fragile, so this planting method is very difficult.
If you prune a part of begonia, you can put it in water and indoors to let it take root and sprout. Once it takes root, take it out and move it into a flowerpot to grow new begonia.
