Perfect Buxus All Year: The Complete Care Guide

Written By Harvey Dyson

The Ultimate Buxus Care Guide

Box plants have had an undeniably tough time in recent years. While box blight has long been a concern, the arrival of the box tree caterpillar has made Buxus care far more challenging. Some gardeners now avoid Buxus entirely, but for such a defining plant in European gardens, it’s unthinkable to let it fade away.

As a long-standing defender of the humble box (and self-appointed member of the “Box Protection Council”), I’m determined to preserve this iconic plant for as long as possible. I’ve developed a year-round Buxus care schedule that has kept my own box hedging and topiary in excellent condition. Yes, it requires commitment, but that’s gardening. And there is still nothing quite like a perfectly clipped, deep green box plant.

Below is your complete month-by-month Buxus care guide to keep box plants healthy, fed, and looking pristine all year!

 

January & February | A Simple Start

Winter care is minimal but important for long-term Buxus health.

  • Clear leaves and debris from foliage to prevent fungal build-up

  • Inspect plants for winter damage

  • Remove snow from hedges and topiary

  • Watch for waterlogging and relocate containers if necessary

  • No trimming or treatments needed

March | Preparing for Growth

This is the first moment to take action in your annual Buxus care routine.

  • Apply Topbuxus Grow (first feed)

  • Optional rejuvenation prune for sparse or leggy plants, box can be cut back hard now and will bounce back well

  • No spraying required yet

April | Pest Prevention Begins

Caterpillar season is approaching, so prevention is key.

  • Hang moth traps mid-month (refresh lures every 6 weeks)

  • Begin monthly TopBuxus Health Mix sprays

  • Apply XenTari only if caterpillars are detected (not yet registered for amateur UK use; hand removal required)

  • Do not trim this month

May | Keep Plants Moving Forward

Your Buxus care programme starts to ramp up as growth accelerates.

  • Apply Topbuxus Grow (second feed)

  • Continue monthly Health Mix sprays

  • Check moth traps weekly and empty if necessary

  • Carry out a light maintenance trim (late May or early June)

June | Time to Get Hands-On

Early summer is when caterpillar activity often increases.

  • Continue monthly Health Mix sprays

  • Refresh moth trap lures

  • Apply XenTari at the end of June if caterpillars are active (hand removal required in the UK)

  • Trim this month if you didn’t in late May

July | Steady Summer Maintenance

The height of the season calls for steady but simple Buxus care.

  • Apply Topbuxus Grow (third feed)

  • Continue monthly Health Mix sprays

  • Check moth traps weekly

  • Maintenance trim (mid–late July)

August | Late-Summer Protection

A crucial month for preventing late-season caterpillar damage.

  • Continue monthly Health Mix sprays

  • Refresh moth trap lures

  • Apply end-of-month XenTari to catch the third generation (UK restrictions still apply)

  • No trimming this month

September | Final Feed of the Year

This last push sets your plants up for autumn strength.

  • Apply Topbuxus Grow (final feed)

  • Continue monthly Health Mix sprays

  • Check moth traps weekly

  • Optional light trim (early September only)

October | Winding Down

Time to tidy up before winter begins.

  • Remove and clean moth traps for winter storage

  • No trimming this month

November & December | Rest and Review

Your Buxus are dormant, and so are you.

  • Clear leaves and debris from around the base of plants

  • Review the year’s treatments and overall plant health

  • No trimming required

Important Notes on Treatments

Always follow manufacturer instructions when applying feeds, sprays, and tonics. Do not over-apply, especially during warm spells.

XenTari and BuxRevive are not yet approved for amateur use in the UK (currently under testing). They must not be used by the public until fully licensed.

Why Consistent Buxus Care Still Matters

Despite the challenges, Buxus remains one of the most versatile, structured, and character-defining plants in garden design. With the right care, and a little determination, you can keep box hedging, topiary, and borders looking exceptional year-round.

Healthy Buxus is absolutely achievable. And with a consistent, proactive approach, you’ll be rewarded with rich green foliage, crisp shapes, and the timeless elegance that only box can offer.
