Different Types of Boxwood Shrubs
Boxwoods are versatile shrubs that can grow year-round. And since they thrive on regular trimming, they’re ideal for hedges and geometrically shaped shrubs to decorate your garden. But the size, appearance, and growth of each boxwood plant depend on the species.
Here are some common types of boxwood you’ll come across:
The English boxwood is ideal for small globes or low hedges that border flower beds and pathways. It’s a popular choice because it requires considerably less pruning. It naturally lends itself to a hedge and topiary form.
Moreover, the leaves are more rounded and denser, giving the plant a relatively compact shape.

This variety of boxwood is a slow-growing plant. It can take years to reach a height of 3 or 4 feet. So if you live in zones 6 to 8, this is probably the suitable boxwood you can invest in.
An American boxwood has dark green, pointy leaves. So it holds an evergreen appearance all year round. It tends to grow faster and looks larger than its English cousin.
Without pruning, the American variety becomes a wide shrub or a small tree almost 15 feet tall. So they’re ideal for taller hedges or clipped structures.

This plant is a native of Japan. And because of its dwarf-like form, it’s also known as the Little-Leaf Boxwood. Moreover, it grows quite slowly, its height reaching up to a few feet.
Though this variety can grow in the sun and shade, it does not thrive well in the cold and may end up losing much of its color. It agrees better in hot areas, such as zones 9 and 10.

This variety is more adaptable to colder climates and can tolerate heavy frosts better than the other types. In fact, it can stay green and healthy even if temperatures drop as low as -20°F.
So, you can plant them in zone 5 and possibly even in some milder parts of zone 4.
Additionally, this type of boxwood is more compact, growing up to about 8 feet tall and 6 feet wide.

How Fast Do Boxwoods Grow?
By now, you have a clear idea of how tall a particular type of boxwood can grow. But you might still be wondering how fast a boxwood actually grows in one year.
You must understand that boxwoods grow very slowly compared to other shrubs. On average, a boxwood typically grows about 6 inches or less every year.
To help you understand what the growth rate for different varieties is, here’s what you should expect:
- Fast Growth Rate = 4 to 6 inches in a year
- Medium Growth Rate = 2 to 3 inches in a year
- Slow Growth Rate = ½ to 1 inch in a year
Factors That Can Influence a Boxwood’s Growth Rate?
The key to growing any boxwood means following a couple of general rules. They not only foster optimal growth but also ensure your plants stay healthy.
Here are some that will help your boxwood grow:
1. Every Species Is Different
Before you implement any rules, you need to identify the growth rate of the species you are planting and their special needs.
For instance, a medium grower like a Faulkner needs plenty of sunshine and space. On the other hand, a slow grower like Green Velvet is much smaller and can thrive even if planted closer together.
Likewise, some boxwoods survive in hotter climates while others thrive at cooler temperatures. By providing the right environment for your plant, you ensure optimal growth.
2. Avoid Planting Too Deeply
Boxwoods grow if planted at the right depth. The crown (the point from where the roots spread out from the trunk) should appear almost an inch above the soil surface.
3. Create A Cool Insulated Root System
Boxwoods grow well when the roots are healthy. To build a cool insulated root system, you need to layer 2 inches of leaf compost or mulch.
However, do not use too much mulch and create a mulching volcano or ring around the truck. This won’t offer enough breathing space around your boxwood.
4. Provide A Good Drainage System
Boxwoods grow well in well-drained, slightly alkaline soil. They cannot tolerate wet soil.
In fact, excessively damp soil causes root rot and increases the chances of boxwood blight and other diseases. This could impact the foliage, turning it brown and making it die.
5. Offer The Right Nutrition
Like all other plants, boxwoods need a healthy dose of sunshine and organic material from the soil. A leaf compost mix works best. It offers beneficial nutrients to the plant.
To protect your boxwoods from winter damage, apply a fresh layer of mulch in the fall.
More importantly, boxwoods prefer the full sun or a light shade. However, avoid planting them in a spot that is too shady. If the foliage does not dry completely, you may end up with boxwood pests and other diseases.
But do keep in mind that there are shrubs you can plant that are drought-resistant. These shrubs may be a good choice in dryer weather climates or areas where there are drought warnings.
6. Apply The Right Fertilizer
There is no one set fertilizer schedule to follow with boxwood shrubs. Fertilizing the boxwood shrubs will depend on the soil it’s planted in.
But, one of the best things you can use is a balanced, all-purpose fertilizer (10-10-10). This helps promote leaf growth in the spring. Applying it again in the fall encourages root growth.
However, avoid adding fertilizer the first season after planting.

7. Protect Them From Severe Weather
Boxwoods don’t like exposed, windy sites, particularly in the winter. If you live in a place that has harsh winters, consider spraying your boxwoods with anti-desiccant and wrapping them in burlap. It reduces the risk of desiccation.
This can happen if the ground freezes and the plant continues trying to photosynthesize. But its inability to draw water up through the roots severely damages or even kills it.
On the other hand, if you are in a hot climate zone, you need to keep in mind that shrubs will need to be watered to be maintained. There are other types of shrubs and plants that do thrive in full and direct sun.
8. Maintain The Plants
Cut your boxwoods to about a third or half of their height. This encourages healthy, bushy branching. But pruning is also a great way to get rid of dying branches. It gives healthy wood a chance to grow.
Since some boxwoods have dense growth, you need to clean them regularly and remove any debris from the center. Thinning out the outer growth allows air and light to reach the center of the shrub. However, avoid trimming in late fall. The new growth may not have enough time to harden before the frost.
9. Plan The Planting
Spring is the ideal time to plant boxwoods. However, you need to choose the right spot. For instance, if you plan to use them as foundation plantings around your house, they’ll grow better on the north side. The south side gets too much direct sunlight, possibly drying out the foliage.
Also, give your boxwoods enough space to grow to reach full maturity. You may plant smaller boxwoods about 2 to 3 feet apart, but the larger ones will need more space, about 3 to 4 feet. Proper spacing allows them to grow to their full size and density.
More importantly, remember that boxwood has shallow roots. So, avoid cultivating the ground or planting other plants too close to their root zone.
Conclusions on How Fast do Boxwood Shrubs Grow
