Begonias are popular Summer bedding plants with green or chocolate brown glossy leaves. These plants produce a remarkable display of bloom and are trouble-free. They are equally happy in sun or shade.
Germination Temperature (°F)
Waterings should be given when compost is dry.
Feed every 3rd watering with high potash fertilizer.
When flowering stops, cut back and re-pot in peat based compost.
Sow seeds on surface in seed and cutting compost. Do not cover seed tray and keep it in light to germinate. Not all seeds will germinate at once.
Begonia Semperflorens can be raised from seeds or from cuttings in Spring. Take 3-6 inches long cuttings taken from shoots near the base of the plant. Cut with a sharp knife between 2 nodes. Remove the lower 2 or 3 leaves and insert the cutting to about half its length into a mixture of equal parts of sharp sand and moss peat. They root in 3-4 weeks. Stem cuttings can also be rooted in water.
Begonia Semperflorens will bloom all year round if it is in the right place. The flowers can be double or single. When grown outdoors as bedding plant, it can be potted up before first frost of Autumn and brought indoors as houseplant in Winter.
Be careful not to remove flower buds when pruning.
When they are seedlings, they need good light but not full sun. When they are plants keep in full sun and well watered. Normal room temperatures are suitable for actively growing plants. They suffer in dry air. Pinch back new stem tips to keep it bushy.
On windowsills or in the garden.
Light overhead spray during Spring to early Autumn. Keep plant on wet pebbles.
Scientists were able to revive a flowering plant from the fossilized fruit found in the stomach of an Arctic ground squirrel who was trapped in ice around 32,000 years ago.
