Prop the basket on a bucket and line it with moist grass clippings. Alternatively you can buy a pre-moulded coir basket. To help retain moisture add a layer of plastic inside this.
Snip a few drainage holes into the plastic, then fill the basket two-thirds full with compost (mixed with water-retaining gel). Plant the tallest plants off centre.
Plant the trailing plants around the edge, where their flowers will quickly grow over the sides.
It's important to keep plants well fed, so give them a boost of liquid plant food, such as tomato fertiliser, at this stage.
Give your plants a good water, and allow to drain before hanging the basket in its final position.
