When to Start Preparing Pearly everlasting for Winter
Monitoring Weather Changes

Begin monitoring weather patterns and plan your preparations to coincide with the start of cold temperatures, typically in late autumn.
Optimal Timing for Preparations
The ideal time to start preparing Pearly everlasting is in mid-fall, around late October or early November. This allows the plant to gradually adapt to the approaching cold. During this period, start reducing watering frequency and begin other overwintering steps to ensure a smooth transition for the plant.
What Steps to Take to Overwinter Pearly everlasting
Pruning the Plant
Pruning is vital for winter readiness, helping to prevent disease and encourage vigorous growth. Cut back the stems to approximately 5-7 cm (2-3 inches) above the ground. Be careful not to over-prune, as leaving some stem and foliage can shield the plant's base from frost.
Mulching for Insulation
Applying a thick layer of mulch around the base of Pearly everlasting can effectively insulate the roots from extreme cold. Use organic materials such as straw, shredded leaves, or bark mulch. Aim for a 5-8 cm (2-3 inches) thick layer for optimal protection.
Watering Techniques
Proper watering before the ground freezes is critical. Reduce watering as fall progresses but ensure the soil remains slightly moist. Water deeply about a week before the first expected frost to provide the plant with adequate moisture, as this helps prevent root desiccation.
Pest and Disease Control
Inspect your plant for any signs of pests or disease before winter sets in. Remove any infected parts to prevent spread during the dormant season. Applying an organic fungicide can also help keep potential diseases at bay.
