When I visited eastern Poland many years ago each house and garden was enclosed with a fence or hedge of some sort. Some fences were wood, some stone, some ornamental iron and some were living fences that divided properties. I thought the living hedges were the most beautiful and neighborly. Whether you need to screen a water tank or noisy road or the neighbor’s second story window there are lots of choices. Fall planting season is still going strong.
Many people only think of plants that remain evergreen when they need screening. However, if you use one-third deciduous plants to two-thirds evergreens they will weave together and you won’t be able to tell where one leaves off and another begins. This makes mature hedges secure borders, especially if you throw a few barberries or other prickly plant into the mix. You’ll also get seasonal interest with fall color and berries for wildlife.
Narrow spaces can be challenging when you need to screen the house next door. There’s not room for a big, evergreen tree or hedge to solve the problem. One way is to use plants that can be espaliered against a fence or trellis. Some plants like azara microphylla naturally grow flat without much coaxing on your part. This small dainty tree is fast growing and reaches 15-25 ft tall. The yellow flower clusters will fill your garden with the scent of white chocolate in late winter. They are ideal between structures. I’ve used the variegated version to screen a shower and it’s working great.
Variegated Mint Bush is another shrub to consider for a living hedge. Creating pleasing plant combinations is a big part of gardening and this one would look great alongside a Fringe Flower of either color. Allow each plant to interweave and grow together. The Mint Bush will grow 4-6 feet tall and 3-5 feet wide. The foliage smells very strongly like mint so deer avoid this shrub, too.
Small trees that make a good screen are purple hopseed, and leptospermum ‘Dark Shadows’. Both have beautiful burgundy foliage. California natives that can be espaliered against a fence include Santa Cruz Island ironwood, Western redbud, mountain mahogany, toyon, pink flowering currant, Oregon grape and spicebush.
If you have a wider space to grow screening plants, one of my favorites is Pacific wax myrtle. This California native grows quickly to 30 ft tall with glossy, rich forest green leaves. Its dense branches make a nice visual and noise screen for just about anything or anybody. Best of all the fragrant waxy purplish brown fruits attract many kinds of birds.
California coffeeberry grows 6-8 feet tall and gets by with very little summer water once established. Birds love the berries. I also like osmanthus fragrans for a screen with its sweet scent and pittosporum ‘Marjorie Channon’ or ‘Silver Sheen’ for their showy variegated foliage. Email me and I’ll give you even more suggestions.
Provide the best growing environment for the fastest results. By this I mean amending the soil at planting time if your soil is not very fertile. Cover the soil with mulch and fertilize with compost or organic fertilizer. Water deeply when needed especially during the first three years when young plants put on a lot of growth.
