Gardening by the Seaside
Gardening by the sea side has a number of unique challenges . Although the climate may be milder, less prone to frost and snow, coastal gardens are often in exposed sites and suffer from sea spray heavy with salt. Many gardens are part of a second home and so the garden must fend for itself for periods.
If the garden is very exposed, it may be necessary to create a wind break or some shelter. A hedge is better than a wall or a fence which can creates wind eddies and be blown down. A mixed hedge can be formed from many of the shrubs listed below.
If garden pots are unattended for periods, a good tip is to add water gel crystals to the soil. They help to retain water as will a mulch, stones and shells can look attractive.
