Container gardening is something to get excited about because of the scope it allows the amateur gardener. You can grow lime loving plants alongside lime hating plants. No matter how small your garden you can have fresh herbs outside your kitchen window, all you need is a window box.
Containers don't have to be expensive, you can use almost anything to grow plants in if you don't happen to have an old Bentley lying around the place. Obviously you're going to want something that's pleasing to the eye but with a lick of paint the world is your oyster.
Containers need to be watered and fed on a regular basis. You can buy purpose made baskets, window boxes and planters with built in reservoirs or you can invest in an irrigation system. It really is all about making the time to water your plants. The larger the container the more able the compost is to store enough moisture to keep the plants healthy but a large container full of compost is heavy.
You can use containers to restrict the growth of plants which are otherwise invasive, a good example is mint. You have a pot with mint growing in it on your doorstep so why stop there? Rosemary is garden hardy along with chives, bay, oregano, thyme the list goes on. If you have a cold greenhouse you can move your herb garden into it to prolong the season.
Even in larger gardens there is a place for containers. A tub planted with spring flowering bulbs can be moved to a spot out of sight when the blooms have passed their best and another brought out to take it's place.
Take a look at Blueberry, Top Hat. White flowers in spring, good flavoured fruits in July and blazing crimson foliage in autumn. It grows to a maximum height and spread of 600mm so it's ideal for a container.
if you decide to give container gardening a try the only thing that's going to hold you back is cramming enough containers into the space available to you.
