Storing tuberous begonias properly before replanting is essential to ensure healthy growth and vibrant blooms. Proper storage prevents rot, disease, and damage during the dormant period. This guide outlines best practices to keep your tuberous begonias in optimal condition until it’s time to replant.
Preparing Tubers for Storage
Before storing, carefully dig up the tubers after the first frost or when the foliage has yellowed and died back. Gently brush off excess soil without damaging the tubers. Remove any damaged or diseased parts with sterilized scissors to prevent rot during storage.
Cleaning and Drying
Wash the tubers in a solution of water and a small amount of fungicide or horticultural soap. Rinse thoroughly and allow them to dry in a well-ventilated area away from direct sunlight. Proper drying reduces the risk of mold and rot during storage.
Choosing the Right Storage Conditions
Store tubers in a cool, dark, and dry location. Temperatures should ideally be between 45°F and 50°F (7°C – 10°C). Avoid areas with high humidity or fluctuating temperatures, as these conditions can promote mold growth or shriveling.
Ideal Storage Materials
- Paper bags
- Cardboard boxes
- Mesh or burlap sacks
Line containers with dry peat moss, vermiculite, or perlite to absorb excess moisture. Do not store tubers in plastic bags, which can trap humidity and cause rot.
Monitoring and Maintenance
Check stored tubers periodically throughout the winter. Look for signs of mold, shriveling, or rot. Remove any affected tubers immediately to prevent spread. If tubers appear shriveled, lightly mist them with water to maintain moisture, but do not soak them.
Preparing for Replanting
As the planting season approaches, gradually rehydrate the tubers by soaking them in water for a few hours. Then, inspect for healthy eyes and sprouting points. Discard any tubers that show signs of disease or damage before replanting.
Additional Tips for Successful Storage
- Label each tuber with the variety and date of harvest.
- Keep tubers in a single layer to prevent bruising.
- Maintain consistent storage conditions to avoid temperature or humidity fluctuations.
- Avoid storing near fruits that emit ethylene gas, which can promote rot.
Following these best practices will help ensure your tuberous begonias remain healthy and ready for replanting, resulting in beautiful blooms season after season.
