Thank you for your question. Yes, trees in large containers can thrive for a long time in Chicago.

Larger planters with the appropriate insulation and drainage layers are recommended. The trees used in this project are maples, but many other varieties of evergreens and even some fruit trees will survive, if they are selected for hardiness and the site conditions. Trees in containers may require more care and upkeep for optimal long term health.

Thank you! Where do you find the insulated containers?

We source fiberglass planter boxes or customize them for our clients with the appropriate lining layers. You can purchase larger planters from local vendors, or online and install 1" - 2" sheet insulation around the sides. We also recommend adding plenty of holes in the bottom, and a drainage material like lava rocks at the bottom, below the soil, using landscape fabric between all layers. We also use customized soil for containers, and do not top soil.
