Supporting Each Other

Plants do not recognize race, economic condition, or social class. Plants can take root in any spot where they can find sufficient sunlight and moisture. Appreciating and nurturing plants can reduce stress, provide food, and promote community.

Nurturing plants can be for everyone, everywhere. Spending time around plants—gardening, spending time in a park, hiking through trees, or playing in a meadow—is good for mental health, promoting relaxation and relief from stress and worries. There are physical benefits to sunlight, fresh air, soothing scents. 

Whether you have a full garden, some house plants, or a few herbs on your windowsill, we encourage you to take time to appreciate the surroundings, smells, and textures, along with sharing your interest with others. Share photos and web links, offer horticultural help and advice, talk to young people about gardening, growing food, and the role plants play in our world. We can all help shape the future for good.
