What is Overwintering?
Overwintering refers to the practice of safeguarding plants from harsh winter conditions, ensuring their survival until the subsequent growing season. This can involve various techniques, such as relocating plants indoors, covering them with mulch, or excavating tubers and storing them in a secure location. For delicate plants like the Four o'clock flower, overwintering is vital for maintaining their health and guaranteeing they will bloom again once the weather warms.
Step-by-Step Guide to Overwintering Four o'clock flower
When to Start the Process
The optimal time to begin overwintering your Four o'clock flower is following the initial light frost in autumn. This occurs when the foliage has begun to recede, but before the ground freezes solid. Early preparation ensures that the tubers remain in good condition for storage.
Preparing Your Four o'clock flower
Start by trimming the foliage of your Four o'clock flower to approximately 10 centimeters (4 inches) above the soil. This simplifies plant management and helps direct energy towards the tubers. Be sure to use clean, sharp tools to prevent unnecessary damage and potential disease introduction.
Digging Up the Plant
Carefully excavate the tubers using a garden fork or spade. Begin digging around the plant, gradually moving closer to avoid harming the tubers. Gently lift the plant from the ground and shake off excess soil. Handle the tubers with care to prevent bruising or breakage, which can lead to rot during storage.
Cleaning and Storing Tubers
Once you have unearthed the tubers, clean them by brushing off any remaining soil. Avoid washing them as moisture can cause decay. Allow the tubers to air dry for a day in a cool, shaded area. After drying, place them in a container with dry peat moss, vermiculite, or sawdust. Store the container in a cool, dark place like a basement or garage, where the temperature stays between 4-10°C (40-50°F) and humidity is low.
Replanting in Spring
As spring approaches and the danger of frost diminishes, it is time to replant the tubers. Select a sunny spot in your garden with well-draining soil. Plant the tubers about 5-8 centimeters (2-3 inches) deep and space them 30-45 centimeters (12-18 inches) apart. Water generously after planting to aid in their establishment. Afterward, maintain a consistent watering schedule.
