Protecting Bees Starts With Better Gorse Control This Winter

As temperatures begin to rise, ecological restoration experts are urging New Zealand landowners to tackle gorse before spring growth and flowering begin, improving weed control while helping protect vital pollinators.

As winter begins to ease across New Zealand, ecological restoration experts are encouraging landowners to start planning their gorse control programmes before spring growth takes hold.

According to Native Restorations Founder Terence Stewart, timing isn't just important for improving the effectiveness of weed control, it can also help reduce impacts on bees and other important pollinators.

"Gorse is one of New Zealand's most invasive plants, and once spring arrives it quickly bursts into rapid growth and flowering," says Stewart.

"One of the biggest mistakes we see is people waiting until spring before they think about gorse. By then it's already waking up and growing rapidly. If you start planning in late winter, you can get ahead of the problem before it becomes much harder to manage."

Introduced to New Zealand in the 1800s as a hedging plant, gorse now infests thousands of hectares of farmland, forestry blocks, roadsides and conservation land, competing with native vegetation and creating a long-term management challenge.

Research shows gorse seed can remain viable in the soil for 30 to 50 years, meaning delaying control today can create decades of ongoing work if infestations aren't managed properly.

Stewart says many property owners underestimate just how persistent the weed can be.

"People often look at what's above the ground, but the real challenge is what's underneath it. A mature stand of gorse leaves behind a huge seed bank, so successful control isn't just about killing today's plants—it's about stopping tomorrow's generation as well."

As daytime temperatures begin rising towards spring, gorse becomes more physiologically active, allowing herbicides to move more effectively through the plant. At the same time, bee activity remains significantly lower than during peak flowering periods, making late winter an ideal opportunity to begin control programmes.

"We're always trying to work with nature, not against it. Timing weed control while bee activity is low is one small decision that can make a big difference for local biodiversity."

However, Stewart says successful restoration doesn't end with spraying.

"Spraying is only the beginning. The properties that stay clear of gorse are the ones where someone follows up, checks for new seedlings and restores the site with native planting. That's where the long-term success comes from."

Replacing invasive weeds with native species helps establish natural shade, reducing opportunities for new gorse seedlings to establish while restoring habitat for native birds, insects and wildlife.

"Nature hates a vacuum. If you remove gorse and leave bare ground, another invasive species will usually move in. When you replace it with native plants, you're giving the landscape the best chance to repair itself naturally."

Stewart says while cutting gorse may appear to solve the problem, it often results in vigorous regrowth unless followed by an ongoing management programme.

"We regularly visit properties where people have spent years cutting the same patches of gorse. Done properly, it's not about doing the job every year—it's about breaking the cycle."

For Native Restorations, successful weed control is about more than removing invasive plants.

"Every patch of gorse we remove creates another opportunity for native species to return. That's ultimately what restoration is about—not simply removing weeds, but giving New Zealand's landscapes the chance to thrive again."

Gorse Control: Terence Stewart's Top Tips

• Start planning your control programme before spring growth begins.
• Spray during suitable weather conditions and always follow product label instructions.
• Avoid spraying immediately before rainfall.
• Follow up regularly to control new seedlings.
• Replant treated areas with eco-sourced native plants.
• Monitor sites annually, as gorse seed can survive in soil for decades.
• Seek professional advice for large or environmentally sensitive sites.
