Dig Up and Clean Bulbs
Timing: Dig up tender bulbs (e.g., dahlias, cannas, gladiolus) after the first light frost when the foliage begins to wither.
Cleaning: Gently shake off excess soil and remove any remaining foliage. Avoid washing the bulbs, as excess moisture can lead to rot.
Cure the Bulbs
Curing Process: Lay the bulbs in a single layer in a dry, well-ventilated area for 1-2 weeks. This step allows the outer skins to dry and toughen, which helps prevent rot during storage.
Ideal Conditions: Cure the bulbs in a spot with good air circulation and temperatures around 60-70°F (15-21°C).
Inspect and Prepare Bulbs for Storage
Inspection: Discard any bulbs that show signs of mold, rot, or pest damage.
Dusting with Fungicide (Optional): To prevent fungal growth, dust bulbs with a fungicide powder before storing.
Pack the Bulbs
Material: Use paper bags, mesh bags, or cardboard boxes lined with newspaper. Avoid plastic containers or sealed bags, as they trap moisture and cause rot.
Insulating Medium: Place bulbs in layers with peat moss, vermiculite, sawdust, or dry sand to help absorb excess moisture and keep them dry.
Store in an Appropriate Location
Temperature: Store bulbs in a cool, dark, and dry place with a temperature range of 35-50°F (1-10°C). Basements, unheated garages, or root cellars are often ideal locations.
Humidity: Ensure the storage area has moderate humidity to prevent bulbs from drying out or becoming too moist.
Air Circulation: Maintain good ventilation to prevent mold and mildew.
Monitor Bulbs Periodically
Check Monthly: Inspect the bulbs every few weeks to ensure they are firm and free from rot or mold.
Adjust Moisture: If the bulbs are drying out, lightly mist the insulating medium to add a bit of moisture. If mold is present, remove affected bulbs and increase ventilation.
Prepare for Planting
Rehydrate (Optional): Before planting in spring, some gardeners soak bulbs for a few hours to help rehydrate them.
Plan Early Planting: Once the danger of frost has passed, plant the bulbs in the garden according to their specific growing requirements.
