Begonia

Begonia

A genus of deciduous or evergreen, shrubs, small tree-like plants, perennials and annuals.

Most Begonias grown in the garden produce spectacular flowering plants, either by virtue of their flower size, or multitudinous numbers of individual blooms, which are produced in a full spectrum of vibrant colours from the purest whites, through pastel shades of apricot, pink, orange, yellow, and red, right up to solid colours.

There are also types grown specifically for their attractive patterned foliage.

However, the plants we are most familiar with are the small fibrous rooted bedding plants Begonia semperflorens so widely used in bedding schemes throughout the UK. Yet, the most magnificent flowers are produced by the tuberous varieties, with upright forms that are best suited to the garden, and pendant varieties used to produce spectacular hanging baskets.

 

General Advice on Cultivation: -

Grow in slightly acidic, fertile, well-drained but moist, soil or compost, in full sun or partial shade.

Keep well watered and feed regularly with tomato fertiliser, and dead-head to prolong the flowering season. 

On tuberous varieties the female flowers should be removed to allow the larger male flowers to achieve full size.

Cut back semperflorens types in Autumn.

Lift tubers in Autumn before the first frosts and store in a dry place over Winter, and restart into growth in Spring by planting in pots and watering.

 

Propagation: -

Sow seed in late Winter or early Spring at 70oF (21oC)

Take stem tip cuttings in Spring or Summer.

Half Hardy to Frost Tender

Pests & Diseases: -

Susceptible to powdery mildew and botrytis  from late Spring to early Autumn.
