Tuberous begonias are among the most popular flowering plants, prized for their colorful blooms and abundant foliage. These plants are native to tropical regions of South America, but they can be grown in many different climates around the world. One of the most important aspects of growing tuberous begonias is knowing when and how to harvest them. In this article, we will discuss the optimal time and technique for harvesting tuberous begonias.
The best time to harvest tuberous begonias is in the fall, when the plants have finished blooming and their foliage begins to die back. This usually occurs in late September or early October. At this point, the tubers will have fully matured and will be ready for harvesting.
Harvesting tuberous begonias is a relatively simple process that can be done in a few easy steps:
Cut back the foliage: Before harvesting your tuberous begonias, you should cut back the foliage to about 2 inches above ground level. This will help the plant conserve energy and make it easier to dig up the tubers.
Dig up the tubers: Using a garden fork or shovel, carefully dig up the tubers, being careful not to damage them in the process. Gently shake off any excess soil and remove any small roots that may still be attached.
Dry the tubers: Once you have harvested your tubers, you should allow them to dry for a few days in a warm, dry location. This will help them cure and prepare them for storage.
Store the tubers: After your tubers have dried, you can store them in a cool, dry location until it is time to plant them again in the spring.
You should wait until the foliage of your tuberous begonias begins to die back in the fall. This is a sign that the tubers have fully matured and are ready for harvesting.
While it is possible to leave your tuberous begonias in the ground over the winter, it is not recommended. The cold temperatures and moisture can cause the tubers to rot, and they may not survive until spring.
You should store your harvested tubers in a cool, dry location. Many people choose to store them in a paper bag or cardboard box with some ventilation holes to allow for air circulation.
You should plant your harvested tubers in the spring, after all danger of frost has passed. This is usually around mid-April, depending on your climate.
Yes, you can divide your tubers before planting them if they are large enough. Simply cut them into smaller pieces, making sure that each piece has at least one growing point.
