How Can I Help?
Bring your water bottles. Learn to grow baby trees. Share them in your community.
Come to a future Free Baby TREES event and learn hands-on skills: collecting seeds, taking cuttings, turning used water bottles into miniature greenhouses, and caring for young trees.
See how we grow baby trees
Bring your bottles, learn to prepare them safely, and practice growing plants from seeds and cuttings.





Bring something. Learn something. Grow something.
♻️ 1. Bring clean water bottles
Save your empty, clean plastic water bottles with caps. Bring them to a confirmed event or contact us to arrange a drop-off. We'll demonstrate how to prepare them for growing seedlings and cuttings.
🌰 2. Share seeds and acorns
Have a tree producing seeds, seedpods, or acorns? Tell us what kind and where it grows. Collect only with the property owner's permission, and keep each species labeled. Seed collection seasons vary.
✂️ 3. Learn to take cuttings
See how to select healthy plant material, make a clean cutting with sanitized tools, and prepare it for rooting. Not every species roots from cuttings; we'll demonstrate appropriate methods for each plant.
🌱 4. Make a bottle greenhouse
Learn how to clean a bottle, safely trim it, add drainage and ventilation as appropriate, fill it with suitable growing medium, and use it to protect a young plant while it establishes.
💧 5. Help care for baby trees
Learn watering, light, labeling, potting up, and how to tell when a seedling is ready for a larger container or an appropriate planting site.
❤️ 6. Share them in your community
Help at a giveaway, connect us with schools or community groups, offer growing space, or invite a local business to sponsor a batch of baby trees.
For safety, adults will handle sharp cutting tools at demonstrations. Bottles are not sealed airtight in direct sun; seedlings need appropriate ventilation, drainage, and monitoring. Please don't bring diseased plant material.
