Tips on how to plant a window box 

How to choose the best window box
Obviously this will mostly come down to taste, but there are some practical things to consider. Most importantly size. Measure your window sill before you order your window boxes to check they will fit both length ways and the depth too. There are a couple of different types of window boxes too – ones that just sit on your window sill, ones that you can wall mount or ones that sit over a railing. 

What soil do you need for a window box?
Treat a window box the same as a pot when it comes to choosing soil. You will need potting compost mix, or any other good quality compost. Ideally, your window boxes should have drainage holes in them, but if they don't you can either drill them in if they are plastic or metal or just add a layer of gravel at the bottom of your box and then fill it up with your chosen soil. 

What plants can you plant in a window box?
Pick smaller plants and flowers that won't spread too far or grow too high. Lobellias, petunias, fuchsias, daisies, pansies, lavender and pelargoniums all make for a lovely colourful window display, but you can also plant herbs and even fruit.
