How to create a green or floral windbreak

If you live right on the coast (or at a higher elevation that receives strong gusts of wind), you might find it a good idea to create a ‘living windbreak.’ Windbreaks reduce wind speeds, protect your garden plants, and give shelter to local wildlife.

While you might think that high walls, rock formations, and solid fences would do the trick and block winds, this is a huge mistake. Winds will simply blow over these solid walls and create eddies in the air. These eddies can make the wind conditions even more severe down in your garden, creating damage and destroying your efforts.

  • Erect a fence or hurdles
    While a solid fence will cause bigger problems than no fence at all, a slatted fence is much more effective. Make sue that your fence is approximately 50% gaps.
  • Hedges are a classic choice – Hedges are a classic choice that look great and keep things in your garden green and lush. Choose a local hedging plant that thrives in your area. Some common choices include hawthorn, escallonia, and rosa rugosa.
  • Trees are a lovely windbreak – Plenty of coastal gardeners have success with rows of tall trees or shrubs as a windbreak. Another option is a tall grass good coastal gardens, ornamental miscanthus grass.
  • Consider a ‘fedge’ – Can’t decide between a fence or a hedge? Go for a ‘fedge’ – a row of braided or woven live willow stems (withies) that will grow into an attractive and effective windbreak.

Exotic Seaside Garden

If you are in a warmer coastal climate such as the South of England, there are some exotic looking plants that thrive[1]. The Jelly Palm is the kind of ‘palm tree’ that you’d expect to see on an exotic holiday abroad; however it’s one of the best coastal garden ideas if you’re looking for something that looks like it’s from across the seas. The Chusan palm also has beautiful exotic looking fan leaves that give that holiday feeling. Arum lilies also love the sea air, and these thrive in a warm coastal garden. This traditional pure white lily flower is just stunning.

Other Coastal Garden Ideas

Of course there are some great tips for coastal gardening[2] that can mean you can grow other plants that aren’t intended for those kind of areas. Ensuring that you create some kind of a wind break if you are in a particularly windy spot can help to let plants and shrubs become more established. The Royal Horticultural Society gives a great comprehensive list of plants that thrive in coastal areas.

Famous British gardener Alan Titchmarsh says[2] it’s no use trying to create a normal garden as most standard lawns, fruit and veg plants and flowers won’t survive the tougher conditions of the coast. He also suggests using nautical themed decoration such as rope, fish netting and driftwood to give that seaside feel that compliments those beautiful plants and grasses for coastal gardens. He also suggests planting with lower ground covering plant that will avoid the wind – the wind will literally swoop over them and so won’t prevent them from growing well. Plants like armeria and Profusion are great ground huggers that grow low.

What types of plants and grasses are good for coastal gardens?

Firecracker  – ‘Cordyline’

Coastal Garden Fruit and Veg

Just because your garden is by the sea it doesn’t mean you can’t grow your own fruit and veg[3]. The main issue is that the soil is very salty, so you need to create the perfect environment for fruit and vegetables to flourish. One great idea is to create a raised bed and fill it with nutrient-rich compost that will be a fantastic foundation for healthy fruit and vegetables to flourish. Also consider using pots, hanging baskets and grow bags to give the same perfect conditions. Leafy vegetables like kale and spinach can grow fairly well in salty soil as can beets and asparagus so if you must plant directly into the soil these are a good idea. As with any fruit and vegetables, coastal plants will need pest control to ensure that the bugs don’t munch your produce before you get the chance.

So there you have it – some great coastal garden ideas to give you a bright, beautiful and perhaps even edible garden if you do like to be beside the seaside!
