How To Fill Gaps In Hedges
Garden hedges provide you with both beauty and privacy for your gardens. However, gaps can make them look unattractive. Do not fret because there are easy solutions that will revive the beauty of your hedges.
Here are some ways to fill the gaps in hedges:
Mask the Bare Bottom
Conceal the void at the hedge's base by planting new and bigger plants in front of it. Choose big plants because smaller ones will not grow enough when it is time for trimming.
Add Flowering Shrubs
You can add your choice of flowering shrubs to hide the gaps and unattractive parts of the hedge. This way, you not only fill in gaps but also add blooms that enhance the hedge's appearance. The small to medium size of the shrubs is ideal as camouflage for a hedge.
Make Use of the Outlying Branches
Try hiding gaps with neighboring branches of plants in the hedge. You can do this by redirecting the shoots of the adjacent plants with some support. Give it time, and the gaps will close.
Add Decorative Garden Ornaments
Showcase your creativity by adding decorative garden ornaments in front of the hedge. There are plenty of hedge decor you can buy online and in gardening stores.
Arrange Wood Gratings, Vines, Trellis, and Structures
Arrange wood gratings, plant vines, trellises, and similar supports to conceal any void area of the hedge. This technique creates an illusion of a filled hedge by adding some structures behind the hedge, such as a fence, brick wall, or stone columns. In that way, the gaps will not be obvious.
Tips When Filling Gaps In Hedges
When you fill in the gaps, there are some tips worth noting:
- The plants you can grow under or in front of the hedge will depend on the type of hedge. You can get some plant ideas here: What To Plant Under Hedges [7 Ideas Including Flowers!]
- When adding new plants, consider the growing room. Hedges have deep and established roots that you might sever while planting. The new plants need more nutrients, so give them enough room to avoid competing with the existing hedge.
- Place the new plants or other structures close enough together, otherwise they will not effectively conceal the gaps. The distance of the masking plants or structures also depends on the type of hedge.
- Regularly water and nourish the plants with fertilizer. By doing so, you also keep the hedge healthy and lively.
- Prevent new gaps from forming by taking care of the hedge. Remove pests and avert diseases that affect the growth of hedge plants.
- If your hedge has gaps on the bottom, dig a 1-foot deep trench in front. Then fill the trench with compost. Afterward, plant contrasting shrubs that can tolerate some dry shade.

How To Fill Gaps In Privet Hedge
A privet hedge is one of the common hedge types. It creates a classic feel but is affordable to create. Privet can grow tall and wide while producing dense foliage. This hedge is popular as a boundary for properties and topiary displays.
They will grow well in the right conditions. Hence, the right maintenance will keep the hedge looking good.
However, there will be gaps that ruin the appearance of the hedge. Just like leylandii, you can also grow to fill in gaps.
For a privet hedge, you can plant the following underneath:
- Sweet woodruff
- Rusty foxglove
Besides adding new plants, you can also cut back the hedge base in the summer. If the base gets sunlight and you prune the vertical tips, it will grow back.
How To Fill Deciduous Hedges (Like Hawthorne And Beech)?
You can add suitable plants for this type of hedge. It is best to choose bare-root or root-wrapped plants to add to the hedge. The best time to fill the gaps is during fall.
Besides planting, you can also cut off the height of the hedge. Although deciduous hedges will shed leaves in fall or winter, they can grow back from old wood. Hedge experts recommend that you renovate during the winter.
Also, you can do hedge laying. You can lay the following plants near the hedge base:
- Field maple
There are courses for hedge laying that you can join to know the best practices.
What Causes Gaps In Hedges?
In addition to learning how to fill the gaps, you should also know what causes them. You must know the causes to prevent or minimize the gaps. The common causes are the following:
Not Enough Sunlight
Most gaps are on the bottom of the hedge. That happens because they do not get enough sunlight. Plants need the sun to photosynthesize, and with shade from the rest of the hedge, the bottom can deteriorate.
Pruning can help keep the hedge's shape, but too much pruning may cause a cessation of growth for some branches. Be careful not to prune the young and budding branches.
Pests And Diseases
Another reason is the presence of pests and diseases specific to a species of hedge. You must act immediately to remove the pests and treat the hedge. With the dense leaves and tall heights, the problems can spread to the whole hedge.
Moreover, there can be gaps due to the weather or season. The cold winter can be harsh for the hedge. Also, you may cause damage to the hedge when recklessly plowing the snow. Storms and strong winds can break the tiny branches and remove the leaves.
Keeping the hedge with no gaps is hard work, but it will surely pay off because you get your desired privacy in your garden.
Hedges create good privacy or boundary for your garden. However, they can develop unsightly gaps.
You can fill the gaps with easy solutions. The most common is adding new plants under the hedge to conceal a bare base. Others have a creative way to hide gaps by adding fences, vines, or walls. Some redirect the tiny branches of the plants to close the gaps.
By filling in the gaps, you maintain the attractiveness of your hedge.
