Do plant caddies allow air circulation for roots?

Yes, plant caddies can allow for better air circulation to plant roots compared to keeping plants directly on the ground or a solid surface.

Here are some features that enable air circulation for plant caddies:

- Elevated Design - Many plant caddies have an elevated design that lifts planters off the ground. This open space underneath allows air to flow freely around the roots.

- Mesh Or Slatted Surfaces - Some caddies have mesh or slatted surfaces that the planter sits on. These allow air to pass through the bottom of the planter to the roots.

- Drainage Holes - Caddies with drainage holes in the surface also facilitate air circulation by preventing water from pooling under the planter.

- Open-Frame Construction - Caddies made with an open-frame metal or wood construction rather than a solid top enable maximum airflow to the roots.

However, it's important to note that the primary purpose of a plant caddy is mobility rather than aeration. For optimal root aeration, using a well-draining potting mix and avoiding overwatering is recommended in addition to using an aerating plant caddy.
