Natural rainfall is not always sufficient for plants, even when they are growing in the garden, so it is particularly important to their health that watering is not neglected when they are growing in containers.
Watering Systems
In their natural surroundings, many plants survive during periods of low rainfall by extending their roots deep into the earth in search of residual moisture. In containers, they are totally dependent on a regular supply of water to keep them alive.
You can cut down on the need to water frequently by adding water-retaining gel to the compost. This swells up as it absorbs water, and releases it back to the plants as they need it.
Irrigation systems that connect the water supply directly to the plants are an excellent way of cutting down on wasted water, because all the water is delivered exactly where it is needed, at the plants' roots. These can be operated by timing devices to suit the needs of the plants.
As well as providing enough water for your plants, you also need to consider how to get rid of rainwater. On a balcony, excess water can usually be drained away without a problem, but on a roof it may be more difficult. The surplus must drain off quickly, or the roof might not be able to bear the weight.
If you are laying flooring, such as timber decking, it must not interfere with the waterproof membrane covering the roof, and it is important that no damage occurs during installation that would cause water to seep into the rooms below. You should also ensure that canopies will not trap water during bad weather.
