Begonias are one of the easiest plants to propagate; most varieties only need a little water to start new roots. They come in infinite varieties (I love the leaves as much as the flowers) and stand up incredibly well as city house plants (requiring relatively low light, rather infrequent waterings (a once-a-week soaking will suffice in a pot with good drainage), and they are undeniably gorgeous. Click below for the how-to.
How to: Propagate Begonias
Prepare a small container by washing thoroughly, making sure to leave no residue of suds. The smaller the container, the better since the cutting will release growth hormones into the water to help the new roots develop. Fill with tepid water.
Snip a large healthy leaf and place it in the water. Leave in a sunny window.
When significant roots show up (2-3 weeks), gently remove the cutting and plant in potting soil in a well-draining pot. Enjoy!
