If you have a secret to keep, a fern can help you. Ferns are ancient and have been on Earth since almost the beginning of time. They are laden with mystery, and for this reason they are ready to hear and keep our secrets.

For this spell you'll need a small potted fern and one small rock. When you won't be disturbed, hold the rock. Now tell the fern your secret. Add any details you can think of. As you do this, project the secret into the rock. When done, press the rock into the soil of the potted fern. You and the fern are now bonded. Tend the plant and nurture it. When the time comes that you no longer need to keep the secret, remove the rock from the soil. Return the rock to nature by gently placing it outside. Continue to tend the fern. You are now bonded with one of Earth's most ancient living entities.
