How to Overwinter Begonias Successfully: Tips and Techniques
How to Overwinter Begonias?
To overwinter begonias, there are three methods to consider: leaving them in the ground, keeping them in pots, or digging up and storing the tubers.
If your begonias have tubers, they can survive in the ground as long as the temperature is above 50°F.
You can also dig up the tubers and store them in a cool, dry, dark location, such as an unfinished basement or heated garage.
If your begonias are fibrous, they can be kept indoors as houseplants during winter.
To ensure successful overwintering, reduce watering in the autumn, cut the stems down to a few inches above the tuber, and gently remove the tubers from the soil.
Check the tubers periodically for rot or pest damage and store them in dry peat, paper bags, or open trays with good airflow.
In the spring, gradually acclimate the begonias back outside after the last frost has passed.

Types Of Begonia Plants For Overwintering
Begonias are popular flowering plants known for their vibrant colors and delicate blooms. There are three main types of begonias commonly grown: tuberous begonias, hardy begonias, and Begonia semperflorens (also known as wax begonias).
Tuberous begonias are larger-flowered and often double-flowered varieties that are commonly grown in containers and flowerbeds. To overwinter them, it’s recommended to reduce watering in the autumn months until the leaves start to turn yellow, indicating that the plant is ready for a period of rest. Once this happens, stop watering the plants and cut the stems down to three or four inches above the tuber. Gently remove the tubers from their pots along with some stems, taking care not to damage them.
Hardy begonias, on the other hand, are more resilient and can tolerate colder temperatures. They can be overwintered by covering them with a thick layer of mulch in well-drained soil. Alternatively, you can bring them indoors to a cool greenhouse or frost-free shed for protection. If you have pot-grown hardy begonias, it’s advisable to bring them indoors and acclimate them to indoor temperatures.
Begonia semperflorens, or wax begonias, are usually grown as annuals and do not require special overwintering care. However, if you want to enjoy these plants again the following year, it is recommended to dig them up and plant them in containers before the first frosts occur. These plants can then be overwintered indoors in a cool room, conservatory, or glazed porch. They need enough light and fresh air, but be cautious about exposing them to too much light, as it can cause the leaves to burn. Pruning the leaves before planting them in a new container is also suggested. Remember to slowly acclimatize the plants to warmer temperatures before taking them back outside.
Proper Care For Tuberous Begonias In Autumn
Tuberous begonias require special care in the autumn to prepare them for overwintering. Reducing watering is essential as the plants prepare for a period of rest. Once the leaves start turning yellow, it’s a sign that the plant is ready to be prepared for winter. Stop watering the plants and cut the stems down to three or four inches above the tuber. This will not only promote root growth but also ensure that the plants are ready for proper storage.
After cutting the stems, the stems will naturally fall away from the tubers, so there is no need to force them. This process allows the plant to focus its energy on the tuber, which is the part needed for future growth. Gently remove the tubers from their pots along with some stems. It’s crucial to handle the tubers with care to avoid damaging them.
Storing And Checking Tubers For Winter
Once the tubers have been removed from the pots, it’s time to prepare them for winter storage. There are several methods you can use to store tubers, depending on your preferences and available resources. Placing tubers in dry peat, a paper bag, or open trays with good airflow are all suitable options.
A temperature of around 50°F (10°C) is ideal for storing tubers. This can be achieved in various locations such as an unfinished basement, heated garage, or root cellar. However, regardless of the storage location, it’s important to periodically check the tubers for signs of rot or pest damage. If any tubers show signs of rot, it’s recommended to remove them using a sharp knife. Removing rotting tubers early on can help prevent the spread of diseases and ensure healthier growth in the following season. By properly storing and checking your tubers, you can increase the chances of successful overwintering.
- Store tubers in dry peat, a paper bag, or open trays with good airflow.
