June is a busy time of year for potting rootstocks in the LREC greenhouses. This month we will be transplanting nearly 3000 seedlings to give them time to grow before budding this fall with various scions for four research projects.
Gerry Perez, Senior Agricultural Technician, is directing the soil sterilization procedure for the potting mix, which we make ourselves. We use a concrete mixer to combine the soil ingredients, pour the mixture into a custom built steam trailer, and then heat the mixture to 210° F for 30 minutes. The pots are also heat-treated at this temperature.
