Window Boxes For Outdoors: Popular Questions

What are the best plants and flowers to fill outdoor window boxes throughout the year? -
For spring, fill your window boxes with daffodils, crocuses, and pansies for a bright start. In summer, choose geraniums, petunias, and trailing ivy to create lush, colourful displays. Autumn is perfect for cyclamen, violas, and heather, while winter window flower boxes shine with pansies, Skimmia, and evergreen foliage. Rotate your plant selection each season for year-round interest and life.
Which materials are best for outdoor window boxes and why? +
Terracotta offers classic style and breathability for plant roots, while zinc metal and polystone provide modern looks with excellent durability and weather resistance. Fibreclay combines lightweight convenience with a traditional appearance, and eco-friendly plastic is a sustainable, easy-care option. All our containers are designed to withstand the UK climate and protect your plants.
How do I care for my window boxes and keep my plants healthy? +
Ensure your window boxes have drainage holes to prevent waterlogging, especially during rainy months. Raise pots on pot feet in winter to avoid freezing, and use quality soil to help your plants thrive. Regularly refresh your plants and flowers to keep your display bright and inviting, and choose the right size and material for your windowsill, balcony, or garden ledge.
