Injecting summer colour in your garden couldn’t be easier, with the introduction of modern varieties of begonia (view our 10 best begonias here). Though frost tender, they’re surprisingly resilient, flourishing in hot and dry, dull, damp and draughty conditions.

Begonias prefer light shade or partial sun, but don’t like scorching midday sun, so keep this is in mind when choosing a planting location. Use a peat-free, multi-purpose compost to plant up your seedlings, being sure to keep it moist but not waterlogged.

Many begonias can be bought as potted seedlings, with several plants in one pot. These can be grown on a windowsill or in a cool greenhouse until ready to plant out. Find out how separate them and plant individually, in our step-by-step guide.
