Plant the thick tubers of  'Prima Donna in fresh potting compost in spring. Use a flowerpot or plant box with holes in the base, so that the water can drain away properly. Cover the base with pot shards or a layer of hydro pellets. Put the potting compost in the pot and place the tuber on top of it. Cover the tuber of the huge begonia with 1-2 cm of soil. Place the tubers approximately 20 cm apart and water immediately after planting. Begonias will flourish in partial shade.

Begonia as bed plant

Thanks to the very rich bloom and sturdy stems, Begonia 'Prima Donna' also makes an excellent bed plant. Try filling a border along the garden path or a bed with box hedges with the beautifully fringed flowers. They make an appearance throughout summer and will draw a lot of attention. Also add fertiliser regularly in open ground.


By regularly cutting away spent flowers, you will encourage the large begonia to reflower. For an extra rich bloom, Bakker recommends mixing fertiliser in the water regularly. The soil around the tuber may not be too wet. In very wet soil the tuber may start to rot. Protect the plant against bright sunlight. The stems and leaves contain a lot of moist and are absolutely unable to resist frost.

Overwintering begonia

It is very easy to overwinter begonia tubers. Uproot the plants after the first night frost. Cut off all stems just above the tuber. Attach a label with the name to the tubers. In this way you will know you are dealing with begonia 'Prima Donna' next spring. Shake the soil off the tuber and place the begonia in a box with peat dust or sharp sand. Store the tubers of Begonia 'Prima Donna' in a frost-free room. Next spring you will be able to plant them again and you will be rewarded with magnificent flowers.


It is possible to make your large begonia tubers bloom extra early. For this, place the tubers of Begonia 'Prima Donna' in moist peat dust from spring, at 15-20 °C. When shoots appear, you can pot them in potting compost. Allow the begonias to get used to the outdoor temperature in early May. You can plant them outdoors in open ground or in a pot from mid-May.
