Tasmanian lavender farms being loved to death by tourists seeking social media photos.

The intertwined nature of agriculture and tourism has helped to boost both industries.

But some farmers say over-enthusiastic visitors are damaging their crops.

Tony and Denise Cox left their tropical fruit farm on New Zealand's North Island and moved to the Tamar Valley in Tasmania's north just over a year ago.

The couple, who now runs a lavender farm and perfumery, said they often saw tourists trample their plants.

"It's hard for me when they decide to use the lavender as an armchair and sit right in the middle of it because the lavender doesn't like that and we've had quite a few bushes which have been broken in the process," Mrs Cox said.

The farmers have lost rows of lavender due to the selfie-seeking visitors, something that can be devastating for a small farm.

"It's very difficult to say no to them because that's what they're here for," Mr Cox said.

While the couple are happy to have the tourists on the farm, they would rather teach them about the plants.

"If someone is interested in plants, I'm more than happy to take them around and show them the different varieties of lavender," Mrs Cox said.

Each variety of lavender has a slightly different smell.

"You've got everything from mint, because lavender is originally a member of the mint family, and then you've got the real moth repellent, insect sort of things, that's not the stuff we're using on a commercial basis but they're there and it gives people the idea of what we do and how we do it," she said.

Meanwhile at Bridestowe, Australia's biggest lavender farm in the north-east of the state, they are facing a similar problem.

Managing director of the farm Robert Ravens said although they asked visitors to keep to the rows and respect the fields, sometimes the temptation was too great.

"Yes, they pick the flowers, they trample on the crop, they do all sorts of silly things," he said.

"There's so many flowers out there that we don't even notice."

Mr Ravens said he understood the importance some tourists placed on taking the perfect selfie.

But he described it as a chicken and egg situation where visitors' photos at the farm led to more people travelling to the property to take shots.

Tetyana Veliazhanina and her boyfriend Ivan Kjokjorovski travelled to the lavender farm from Europe.

Mr Kjokjorovski was tasked with being the photographer for the day to help his partner take the perfect photo for her social media accounts.

"Hopefully she will get a lot of followers," he said.

The couple said the farm was the perfect backdrop for their photo shoot.

"All the pictures look really nice, that's why it's really hard to choose which picture to post on the internet," Ms Veliazhanina said.

Biosecurity risk from dirty shoes

Whilst the destruction of lavender plants is unwanted, Mr Ravens' biggest concern is the biosecurity risk that comes with a number of tourists entering the farm grounds on a daily basis.

"Our biggest risk going forward is biosecurity because tourists have shoes and shoes have been in contact with contaminated ground in Asia or in Europe," he said.

"Biosecurity remains utmost in our minds, in terms of preserving the lavender that we have here."

Regardless, visiting a lavender farm remains a bucket-list experience for many Tasmanian visitors.
