Yes. Every tree is planted by a partner we've vetted, such as EarthLungs in Kenya and Sadhana Forest in India. For most projects, the partner sends a planting report with the date, the place, the crew and photos, which you can see on our planting record and on each gift's own page.

For Sadhana Forest's projects, each project page shows where the site is, and we share updates and photos from their sites in our project stories. Their forest in Auroville is open to visitors every day, and their site in Kenya welcomes volunteers all year.

Trees are planted in shared batches, many gifts at a time, so the photos show the planting your trees were part of rather than one particular tree. Where a partner sends planting reports, they come with the date, the place and the crew who planted.

When the season is right at each site, so it can be a few months after your gift. For projects with planting reports, the gift page shows the report as soon as it arrives, and we email you when it does.

You choose the project. Our partners plant the mix of native species that suits each site and season, and every project page lists the species they plant there.

On the date you choose. We email it to the gift receiver, with a copy to you, or just to you if you'd like to give it in person.

From $2 a tree, depending on the project. Each project shows its price per tree.

Yes. The certificate arrives as a high-resolution file, ready to print and frame.

It depends on the project, because each partner works the way that suits its place. Everywhere, they plant native species that suit the site, so the trees can thrive on their own once they take hold.

• Local crews, paid fairly. In Kenya, EarthLungs employs people from coastal villages to plant mangroves, and digs channels that bring the tide water back to the young trees. In Brazil, a local team keeps watch over the mangroves at Primeira Cruz.
• Forest professionals. In Oregon, American Forests' crews replant burned land, with seedlings grown from seed collected nearby. In Florida, the longleaf pine forest is kept healthy with controlled burns, the way it has always needed fire.
• Women-led groups. In Haiti, fruit and flowering trees are planted with women-led groups, alongside the bees that pollinate them and the honey they make.
• Volunteers and families. At Sadhana Forest in Auroville, volunteers who live on the land plant and care for the forest. In Sadhana's food forest projects, food trees go in around people's homes, and the families who look after them eat what they grow.
• At sea. In British Columbia, young kelp is grown in a nursery and planted out on lines in the sea, where the team keeps an eye on how it grows.

At some sites, a used plastic bottle is buried next to the sapling, with only its neck above the soil. A cotton wick in the bottom carries water straight to the roots, so far less water is lost to evaporation, and the bottle gets a second use.

It gives the photo a sense of scale. With the stick standing beside the seedlings, anyone looking at the photo can see how big they were when they went in and how far apart they were planted. It's part of what makes a planting report something you can check, rather than just a nice picture.

Yes. Companies and organisations gift trees to clients, teams, artists and event guests, and get a dashboard showing their impact. See corporate gifting.
