Helen Bostock

Helen is a Senior Horticultural Advisor, working with the Plant Health and Gardening Advice teams maintaining more than 1,000 online advice profiles, answering members’ gardening questions and conducting research into garden biodiversity

What do you do?

I’m researching garden biodiversity and how the plants we grow affect garden invertebrates – these are the unsung heroes of a well-functioning ecosystem and the foundation of many food webs. Changes to invertebrate populations can have a huge impact on local environments. Understanding the implications of how our choices affect invertebrates will help us better care for wildlife.

I am spokesperson for the RHS Plants for Bugs study, which was tasked with researching how the geographical origin of plants affects invertebrate abundance and diversity. I support the RHS Plants for Pollinators initiative which compiles lists of the best nectar- and pollen-providing plants for insects and I raise awareness of the importance of gardens and gardeners in our fight to protect UK wildlife through the Wild About Gardens Campaign.
Science needs communicating well to gardeners. I take pride in my role within the Advisory team where I advise RHS members through the RHS Gardening Advice Service as well as improve online advice, which is accessible to all.

“Gardeners care about the impact they have on the environment and I’m excited to help develop this awareness and advise on how we might all improve our gardens for wildlife.”

Why is your team’s research important?

Gardeners and gardens are of huge importance to the environment and biodiversity. Small changes to the way we live can have a huge impact on our neighbourhood and the wildlife it supports. The work I am involved in helps give gardeners confidence to choose the best plants for pollinating insects, or make decisions about whether to plant native or non-native plants to maximise their space for invertebrates.

Projects I’m working on now

Completed projects

  • Plants for Bugs: a project investigating invertebrate abundance and diversity in assemblages of native and non-native garden plant species
  • Blooms for Bees: a citizen-science app-based project to discover bumblebee flower preferences in gardens and allotments


Receiving the Garden Media Guild’s Environmental Award for disseminating the results of the Plants for Bugs research was a huge achievement. The award is presented to work that is “inspiring, informative, entertaining and promotes a positive change”. I was thrilled to be nominated.
