Aeration holes for nursery pots

Today, Ventura County Cooperative Extension's Maren Mochizuki shares with us about 
a local research project.

Do plastic nursery pots with aeration holes improve plant growth compared to standard containers?  UCCE Los Angeles Farm Advisor Don Hodel, UCCE Ventura Farm Advisor Jim Downer, and UCCE Ventura Staff Research Associate Maren Mochizuki have recently completed a 3 year study on the effect of four pot types over time on kentia and king palms (number of new leaves, stem caliper size, aesthetic quality, and root dry weight).

Preliminary results were presented on Aug. 3 at the ASHS annual conference in Palm Desert, CA.  To view the presentation abstract, please visit http://ashs.confex.com/ashs/2010/webprogram/Paper4301.html.
