Giant Patio Begonias Mixed - Tuber
Plant the large tubers of the Patio Begonias in spring in fresh potting compost. Choose a pot or planter with holes in the base so that the irrigation water can easily drain through. Cover the bottom with a layer of potsherds or hydro grains. Put the compost in the pot and place the tubers on top spaced approximately 20 cm apart. Cover the tubers with 1-2 cm of compost. Water immediately after planting. These begonias grow and bloom well in partial shade.Patio Begonias as a border plant
Due to their very rich and strong-flowering stems, Patio Begonias also make great border plants, planted in groups or along the garden path. They appear throughout the entire summer and will attract many admiring glances. Apply a fertiliser regularly when planted in the garden.
If you want your Patio Begonias to flower earlier you can 'withdraw' them. Place them in a shallow tray in moist compost at 15-20˚ C during the month of April. When shoots begin to appear, place them in potting compost. By the beginning of May, you should let them get used to the outdoor temperature and you can plant them from mid-May onwards in either your garden or in a pot.
Deadhead the faded flowers to encourage further flowering throughout the growing season. When the plant is established it is often advisable to provide a regular liquid feed, which will help to encourage an extra rich flowering. Protect them from direct, bright sunlight. The compost around the tubers should not be too wet as this may cause the begonia tubers to rot. The stems and leaves contain high amounts of moisture, therefore they can definitely not tolerate frost.Overwintering begonia
Begonia tubers are easy to preserve during the winter. After the first night frost and when the begonia foliage begins to yellow, reduce watering until the pots dry out. Lift the begonias and cut the stems back to just above the tuber. Attach a label with the name of the Begonias to remind yourself for the next year. Shake the compost from the begonia tubers and place them in a box with compost or sharp sand. Keep the tubers in a frost-free area. Next spring, you can plant them once again and the plant will reward you with its beautiful flowers.
