You should water your begonia once a week if the top later (an inch) is dry. It is the most important part of it’s care – keep it moist but not overwatered!

When To Repot

Begonias are comfortable when pot bound, and in fact they prefer it, o you can leave them be for quite a while. But if they have really, really crowded roots then pot it up one size in spring.


Begonias love 50% humidity, or they can get crispy leaves from drying out.

How To Propagate A Begonia Maculata

The easiest way to propagate a begonia maculata with with water propagation. Cut off a cutting and put it in a jar of water to allow it to root before potting it up. Take the cutting and let them callous over for an hour or so so the wound heals. Then put then in a jar of water to root.

I have also had some good results from taking node cuttings and putting them in wet sphagnum moss to root new plants, then potting up to soil after a month or two.
