Begonia Plant Propagation

Begonias are propagated from seed or cuttings. Begonia seeds are very fine, dust-like, and take two to three weeks to germinate. Many people will buy seedlings rather than try to start these tiny seeds. Cuttings are much easier if you want to propagate a few plants and already have one.

Tuberous varieties are commonly propagated by separating and replanting the tuberous roots.

How to Grow Begonias Flower Plants

Begonia flowers are annuals and do not like frost in the spring or fall. Set them out in containers, hanging baskets, or your flowerbed after all risk of frost has passed.

Begonias thrive in a range of sunlight from full sun to shade.

They like rich, loose, and fertile soil that drains well. Water thoroughly, then allow the soil to dry before the next watering.

Begonias like attention. Remove dead flowers, leaves, and stems. Trim off long stems to help retain their compact shape. A little care will pay you back with lusher foliage and more blooms.

Add a general-purpose fertilizer once a month. For houseplants and container plants, give them a dose of liquid fertilizer once a month instead of dry fertilizer.

You can harvest begonia seeds for planting next year. Harvest seed pods when they become dry and before they open and spill out the seeds. Remove them from the seed pods. Then, allow them to dry for a week before storing them for next year.

Insects and Plant Disease

There’s great news here! Your begonias should have few if any problems with insects or disease, indoors or out.

Bringing Perennial Begonias Indoors as Houseplants

Your Begonias can be brought indoors before frost. Remember, they will die in a light frost, so if one threatens your area, don’t wait!

Re-pot the plants if they appear crowded. Use rich potting soil. Help them in their transition indoors. When first brought inside, keep them near a sunny window, gradually, reducing the sunlight. This will help them to adjust indoors. Significant leaf drop is common at this point. But, in a week or two, they will be well acclimated to lower light levels and dry conditions in your home. They will brighten up your home all winter!
