A new study from Britain's Royal Horticultural Society found that, among the 6,000 people surveyed, those who garden everyday have 6.7 percent higher well-being and 4.2% less stress than those who never garden. Even just being in the presence of greenery and plants offers a boost. The study's lead author and RHS Well-Being Fellow Dr. Lauriane Chalmin-Pui also said that her team found that greater proportion of plants in the garden was linked with greater well-being. "Most people say they garden for pleasure and enjoyment so the likelihood of getting hooked to gardening is also high, and the good news is that, from a mental health perspective, you can't 'over-dose' on gardening!" she said.
