How to Make Boxwoods Grow Faster: The Simple Steps
Boxwoods can grow faster if you give them exactly what they need.
But a lot of homeowners assume boxwoods are naturally slow growers and nothing can change that.
That’s not entirely true though.
You can make boxwoods grow faster by focusing on soil health, watering habits, light exposure, and the right feeding routine.
In this post, we’ll break down how to make boxwoods grow faster with practical steps you can start using today.
Let’s dig in.
How to Make Boxwoods Grow Faster With the Right Conditions
The secret to faster growth is creating an environment where the roots feel happy and the leaves can photosynthesize efficiently.
Here’s what matters most when you want to make boxwoods grow faster.
1. Start With Rich, Well‑Draining Soil
Boxwoods grow faster in soil that drains well but still holds enough moisture for the roots.
Heavy clay soil suffocates the roots, while sandy soil dries out too quickly.
The best mix for faster boxwood growth is loamy soil amended with organic matter like compost or aged manure.
Aim for a pH between 6.5 and 7.5.
Test your soil before planting, and if the pH is off, your boxwoods won’t grow faster no matter how much you water.
2. Water Deeply, Not Often
When you want to make boxwoods grow faster, watering correctly is half the battle.
Shallow, frequent watering encourages roots to stay near the surface, which makes the plant stressed during dry spells.
Instead, give your boxwoods a deep soak once a week during the growing season.
A deep drink forces roots to reach down into the soil, which helps boxwoods grow faster because they can access more nutrients.
Always water at ground level and avoid wetting the foliage.
Wet leaves invite fungal diseases that slow growth.
3. Give Them Plenty of Sun (But Not Too Much)
Boxwoods grow faster when they get about 4 to 6 hours of direct morning sun each day.
Afternoon shade is important in hot climates because intense heat can scorch the leaves.
If your boxwood is in deep shade, it will grow slowly and become sparse.
To make boxwoods grow faster, choose a spot with dappled sunlight or morning sun followed by afternoon shade.
If your current spot is too dark, consider transplanting or trimming back overhead branches to let in more light.
The Best Fertilizer to Make Boxwoods Grow Faster
Feeding boxwoods the right way gives them the energy boost they need.
But using the wrong fertilizer can do more harm than good.
Here’s how to feed boxwoods so they grow faster without burning the roots.
1. Use a Balanced Slow‑Release Fertilizer
Look for a fertilizer with an N‑P‑K ratio around 10‑6‑4 or 12‑4‑8.
The nitrogen (the first number) promotes leafy growth, which is exactly what you need to make boxwoods grow faster.
Apply it in early spring, just before new growth starts, and again in early summer if needed.
Avoid high‑nitrogen fertilizers after midsummer because tender new growth may not harden off before frost.
Slow‑release formulas are ideal because they feed the plant steadily instead of dumping all the nutrients at once.
2. Try Organic Options for Gentle, Steady Growth
If you prefer organic methods, compost tea or fish emulsion can also make boxwoods grow faster.
These natural fertilizers improve soil health while delivering a mild dose of nutrients.
Another great organic option is well‑aged manure worked into the top few inches of soil.
Just make sure the manure is fully composted so it doesn’t burn the roots.
Organics tend to work slower than synthetics, but they build long‑term soil fertility that keeps boxwoods growing fast year after year.
Pruning Techniques That Make Boxwoods Grow Faster
Counterintuitive as it sounds, pruning actually encourages faster growth.
When you prune correctly, you remove old, unproductive wood and stimulate new shoots.
Here’s how to prune to make boxwoods grow faster.
1. Prune in Early Spring Before New Growth
The best time to prune boxwoods for faster growth is late winter to early spring, just before buds swell.
Pruning at this time triggers a flush of vigorous new growth as the weather warms.
Avoid heavy pruning in late summer or fall because the plant will try to put out new growth that won’t survive winter.
2. Thin the Interior, Don’t Just Shear the Surface
Many gardeners only shear the outer foliage to keep boxwoods tidy, but that makes them grow slower over time.
To make boxwoods grow faster, you need to open up the interior.
Use hand pruners to remove a few of the oldest stems right at the base.
This lets light and air reach the center, which encourages new growth from the inside out.
A boxwood that’s thinned every year will be denser and grow faster than one that’s only sheared.
3. Remove Dead or Diseased Wood Immediately
Any branch that’s dead, damaged, or diseased drains energy from the rest of the plant.
Snip it off as soon as you see it.
By removing these energy sinks, you redirect nutrients to healthy stems, which helps boxwoods grow faster.
Common Mistakes That Slow Down Boxwood Growth
Even with the best intentions, a few missteps can keep your boxwoods from reaching their full speed.
Avoid these common errors to make boxwoods grow faster.
1. Planting Too Deep
Boxwoods are shallow‑rooted plants.
If you bury the root ball too deep, the stem can rot, and the plant will struggle or die.
Always plant at the same depth the boxwood was growing in the nursery pot.
The top of the root ball should be level with the soil surface.
2. Overwatering or Poor Drainage
Boxwood roots need oxygen.
If the soil stays soggy, the roots suffocate and growth stops.
Make sure the planting area drains well.
If your yard has heavy clay, consider planting boxwoods in raised beds or mounds.
3. Ignoring Mulch
A 2‑inch layer of organic mulch (shredded bark, pine straw, or leaf compost) keeps the soil cool, moist, and weed‑free.
Mulch also adds organic matter as it breaks down.
This healthy root environment helps boxwoods grow faster.
Just keep the mulch a few inches away from the trunk to prevent rot.
So, How to Make Boxwoods Grow Faster?
Boxwoods can grow faster when you give them proper soil, deep watering, balanced sun, and smart feeding.
Combine that with correct pruning and avoid common mistakes, and you’ll see noticeable improvement in growth rate.
Remember that even with all these tricks, boxwoods are not speed demons — they naturally grow about 2 to 4 inches per year.
But with the steps above, you can push them to the upper end of that range and enjoy a fuller, healthier plant sooner.
Hope this guide helps you make boxwoods grow faster in your own garden.
