Try Dried Flowers
Brie’s Honeybees & Flowers says, Use dried flower bouquets, boutonnieres and flower crowns. They don’t have to be in water the day of your wedding, which keeps things earth friendly, and you can keep them after the wedding! This is perfect for destination weddings because they can be shipped or for fall weddings that feel a bit more rustic.

Ceremonially Plant a Tree
TOAST Santa Barbara says, Rather than lighting a candle together, or combining sand, one of our couples decided to ceremonially plant a tree together as the start of their marriage! I LOVE this idea and think it’s a great inspiration.
Encourage guests to plant trees & flowers by offering seeds or succulents as favors!
Bluebird Productions says, Put a little extra thought into decor to reduce waste! Would live plants supplement cut flowers nicely with your design? Can you use soy wax candles? A lovely linen using natural fibers versus manufactured fibers will reduce your carbon footprint as well.
