Planting Coastal Hedging Plants
Gardening beside the sea takes special consideration. The salty sea air is often intolerable to some species and varities of hedging plants. It is therefore important to choose species carefully when planting along the coast. The majority of suitable species are in fact evergreen, offering colour, shelter and protection to the coastal garden all year round.
The benefits of planting hedging in your coastal garden are extensive including:
- Privacy and shelter
- Filter against pollution
- Assist in the maintenance of healthy soils
- Provide shade from the Sun, shelter from the elements
- Produce food for smaller animals, birds and mammals in the ecosystem.
- Evergreen hedging plants Bring colour into the garden space all year round.
When conditions are harsh, we must then choose wisely to maximize the return from our investment in that space. Here’s a few options for hedging plants that thrive in coastal areas in Ireland.
Elaeagnus x ebbingei

They take a pruning well and pruning once in a 3 year cycle improves flower and berry yields.

Planting your Coastal Hedging Plants
Planting takes time, effort and after care. Keeping new planted hedges free from weeds and grass in the first few months after planting is important. Weeds and grass are competition for nutrients.
Before you get started, can we advise that you read our Guide to Planting or alternatively you can watch our Step By Step Guide.
Please be mindful, as with all plants and living things, trees need water to survive and thrive, especially in the few months immediately after planting.
Watering should be carried out early morning or late in the evening and consistently in drier Summer months to give your hedging the best possible start.
Regular feeding of these coastal hedging plants with a nitrogen-based feed is also recommended. You could work Chicken Manure pellets into the soil when planting to add vital nutrients that will promote growth and plant health.
