Why does the Smart Pot have a fabric bottom?
To help you grow a better plant. The Smart Pot is made with a heavy porous fabric bottom that gives a plant intimate ground contact. This ground contact helps the plant maintain a ground temperature, as opposed to a plastic container temperature. Also, small roots may penetrate the bottom of the Smart Pot. These roots will help intake moisture and nutrients.
My plants were growing well until I moved them. What happened?
Water the plant! Because of the fabric bottom, if the plant is moved to a dry ground area, the dry ground can move water out of the Smart Pot by capillarity. Water when you move plants.
What other advantages are there to growing in the Smart Pot over traditional, plastic containers?
The fabric will not crack or break from frost or when dropped. Heat release gives you better control of slow release fertilizer. A fibrous root structure has fewer problems in cold or warm weather.
How does the Smart Pot work?
Smart Pots are manufactured out of a custom, non-woven, polypropylene material that research discovered has important and unique horticultural applications. As roots grow they soon reach the container walls. In hard sided, plastic containers, these roots immediately start circling and continue to circle. Examine a circling root structure and you find a few large roots growing in circles with very little side branching. These roots often bind or girdled upon themselves. Circling roots can never give optimum growth.
Smart Pots are manufactured out of a tough, porous fabric. When roots reach the side of the Smart Pot, they Air Prune!
What is air pruning?
Air pruning is a natural process occurring when a root comes in contact with the air on the side of the porous Smart Pot wall. The root tip stops growing (pruned) and causes the remaining root to extensively branch. Now, instead of fewer circling roots, the plant develops new lateral roots. New, fibrous roots fill the Smart Pot allowing the plant to maximize uptake of both moisture and nutrients. And when the roots grow well, the plant grows well. Upon comparison, root systems that developed in a Smart Pot have a much greater mass or volume then those found in hard-sided plastic containers. Plants grown in Smart Pots have greater root mass in less soil.
