Talk to your friends or relatives if they are interested in home gardening ~ if they already have one, that would even be better since they can share tips and tools
A network of 3-4 families are the best, which means you will be meeting 3-4 times together
Schedule a time that everyone is available to do a gardening workout
On the workout day, bring whatever (e.g., tools, plant starters, seeds, snack) that you would like to share
Remember to start small even with just a few pots! Gardening should be relaxing and enjoyable!
