What size windowsill planter should I choose? For small windowsills, herbs and compact flowers, choose a 21cm, 30cm, 32cm or 33cm windowsill plant pot.

For larger windowsills, balconies, patios and longer displays, choose a 52cm, 54cm, 60cm or 90cm plastic window box. Why choose plastic window box planters? Plastic window box planters are lightweight, affordable and practical for everyday gardening. They are easier to move than ceramic, stone or terracotta planters, and they are simple to clean and reuse when changing seasonal displays. Best plants for windowsill plant pots Windowsill plant pots are ideal for herbs, bedding plants, strawberries, lettuce, small flowers, trailing plants, pansies, petunias, geraniums, lavender and seasonal displays. Use them indoors on a bright windowsill, outdoors under a window, or on a balcony or patio ledge. Window boxes for flats, apartments and balconies Window box planters are a great option if you live in a flat, apartment or home without a large garden. They let you grow herbs, flowers and small plants in a compact space while adding colour to windows, balconies and outdoor seating areas. Do windowsill planters need drainage? Outdoor windowsill planters should have drainage holes so excess water can escape. This helps reduce the risk of waterlogging and root damage. If using a planter indoors, place it on a tray or saucer to protect your windowsill from water.
