1 Pick your pots
When planning your display, the advice given by expert Rob Cassy, author of 101 Ideas: Gardens, is always to pick your pots before your plants, as then you can go for greenery that will grow happily in the size of vessel you invest in. 'This way, your flora will be more likely to survive and require less attention in the long run', says Rob. Think about available space and consider it in the same way as you would any other room in the house.

• Measure up to ensure your containers aren't too big or too small.
•Consider weight – can your roof terrace or balcony support a heavy trough full of damp compost and plants?
• If pots or boxes are to be placed up high, ensure they are secured properly and are in no danger of falling and causing injury.
• Large tubs will take far longer to dry out than a tiny pot, which on a hot summer day will lose its moisture faster than you can say 'hosepipe ban', and drenching a couple of large containers is a lot less time consuming than watering a dozen small pots.

Almost anything can be used to accommodate plants. From a reclaimed butler's sink to an old paint tin, the pot you pick can be your own preference, as long as it has adequate drainage. But do take into consideration the area you're looking to fill and pick a style of container that's sympathetic to the surroundings.

Pot Materials

Some types of planter make tending your foliage less hassle. Choose from:
• Terracotta – A good all-rounder when it comes to looks, but its porous nature means compost inside will dry out more quickly. Line with plastic before adding plants, or choose a glazed pot, which will minimise moisture loss.
•Plastic – Terracotta look-a-likes can be very convincing and modern tubs come in all colours, shapes and sizes. Plastic pots need less watering as they retain moisture and are cheap and lightweight, making them ideal for roof terraces and balconies. If you place them in a windy spot, make sure they're properly weighted down so they won't blow over.
•Galvanised – Metal containers look great in a contemporary setting and are non-porous, so need watering less frequently. However, if they're left in a sunny spot they can become very hot and scorch the roots.
• Wood – Crates or half barrels age beautifully and have a great natural look, but they can be really heavy to move. Check if your space is strong enough to support a full container.
•Stoneware – Looks beautiful, but again can be quite heavy. Resists frost well.
