On April 2, 2014 I purchased two 1-year old Page mandarin trees from Four Wind Growers to run a test. One tree was placed in a standard citrus growing medium. The other tree was placed in a cedar mulch growing medium (plain citrus wood chips with no filler added). At first I had to water the ceder wood chip tree every other day. Being just a 1 year old tree, its root system was quite small. As of today both trees have been growing in their 3-gallon Air Root Pruning Containers for 70 days. Both trees are currently flushing, which means their root systems have completed their growth cycle. With their larger root systems, the tree growing in plain cedar wood chips only requires watering once every 4 or 5 days. The tree growing in cedar looks very healthy and is putting out a flush from just about every branch . The high root zone aeration (oxygen) level of the cedar chips is a medium that cannot be over watered, thus cannot damage the tree no matter how much water is applied. In another month or two, I expect that the cedar will only require watering once every 10 days or so, as by that time many of the roots will have grown into the wood chips it self. Time will tell which Page Mandarin will out perform the other. Current they are both doing about the same. - Millet
