Collecting

Bonsai may be developed from material obtained at the local garden center, or from suitable materials collected from the wild or urban landscape. Some regions have plant material that is known for its suitability in form - for example the California Juniper and Sierra Juniper found in the American West, and Bald Cypress found in the swamps of Louisiana and Florida.

Collected trees are highly prized and often exhibit the characteristics of age when they are first harvested from nature. Great care must be taken when collecting, as it is very easy to damage the tree's root system (often irreparably) by digging it up. Potential material must be analyzed carefully to determine whether it can be removed safely. Trees with a shallow or partially exposed root system are ideal candidates for extraction. There is a legal aspect to removing trees, so the enthusiast should take all steps necessary to ensure permission from the owner of the land before attempting to harvest. If not, consider the right of the plant to stay where it is undisturbed..
