As the chilly winds of winter approach, many of us in Staffordshire and the wider Midlands area begin to worry about the safety of our beloved wall planters. Over the past 15 years as a professional gardener, I've learned a fair bit about keeping these plants safe during the colder months. Here’s a practical guide to help you keep your wall planters thriving until spring.
Quick Answer
To overwinter plants in wall planters, move them to a sheltered location, insulate the containers, and use protective coverings to shield them from frost.
Assess Your Wall Planters
First and foremost, evaluate the condition of your wall planters. Check for any cracks or damages that could worsen in freezing temperatures. Repair or replace them as needed to prevent further issues.
Choose the Right Plants
Hardy vs. Tender Plants
Knowing which plants can withstand the winter is crucial. Hardy plants like ivy and certain types of ferns are better suited for colder weather, whereas tender plants such as geraniums may need extra protection or relocation.
- Hardy plants can remain outside with minimal protection.
- Tender plants may need to be moved indoors or given extra insulation.
- Identify plant hardiness to determine care needs.
Protecting Your Plants
Insulate Your Planters
Use bubble wrap or hessian sacks to insulate your wall planters. Wrap them securely, ensuring that the material covers the container completely. This helps maintain a stable temperature around the root zone.
Move to Sheltered Areas
If possible, relocate your wall planters to a more sheltered area, such as under an eave or against a south-facing wall. This can protect them from harsh winds and excessive rainfall typical of the UK winter.
Watering and Maintenance
During winter, water your wall planters sparingly. Overwatering can lead to root rot, especially when the soil doesn't dry out quickly. Check moisture levels regularly, and water only when necessary. Remove any dead foliage to prevent disease.
