Begonia maculata Care Guide

Begonia maculata, often called the Polka Dot Begonia, is one of those plants that always gets a reaction. With olive green leaves scattered with silver spots and deep red undersides, it looks almost hand painted. Despite its dramatic appearance it is not nearly as demanding as most people expect. Once it settles into a steady place and a simple rhythm it grows happily and rewards you with elegant wing shaped leaves and small white flowers that seem to appear when you least expect them. In our barn it is the plant visitors point at first.

If you live somewhere warm, gardeners often grow Begonias outside in shaded porches and balconies, especially in parts of the southern United States. Here in the UK, maculata stays indoors with us, protected from cold nights and grey winter mornings.

Begonia maculata light
Begonia maculata likes bright indirect light. A curtain filtered windowsill or a bright room that stays lit throughout the day is ideal. Too much direct sun can scorch the spots, while too little light stretches the stems and dulls the contrast. A gentle east facing window is often perfect in a UK home.

Begonia maculata watering
Let the top layer of compost dry slightly between drinks. When you water, do so thoroughly and let the excess drain away. Begonia maculata is sensitive to overwatering and the stems can soften if the root ball stays wet for too long. Touch the compost to check rather than following the calendar. It is an easy plant once you learn to listen that way.

Begonia maculata humidity
Maculata enjoys moderate humidity but most homes provide enough without extra effort. Older properties with central heating can dry the air in winter so avoid placing the plant directly above radiators. Crisp leaf edges are usually a sign of dry air.

Begonia maculata temperature
A steady temperature between sixteen and twenty four degrees suits it well. Avoid cold draughts or placing it too close to heaters. Sudden drops in temperature can cause a few leaves to fall.

Begonia maculata soil and repotting
Use a well draining indoor compost mix. Repot every one to two years in spring. Choose a pot only slightly larger than the existing one. Begonia maculata enjoys a snug pot and does not want to be moved more than necessary.

Begonia maculata feeding
Feed every two to four weeks in spring and summer with a balanced liquid feed. Stop feeding in winter when growth naturally slows.

Begonia maculata toxic to pets
This plant can be toxic if eaten, so place it away from pets and curious youngsters.

Begonia maculata pests
Spider mites, mealybugs and aphids can sometimes appear, particularly in warm spells. Check the undersides of the leaves now and again. Early detection makes these small pests easy to manage.
