Dr. Elliott’s retirement party

Dr. Elliott is fixing to retire on August 1, 2016. We had a fish fry to help celebrate his retirement. People recounted all that he has done for our State Fruit Experiment Station and for each of us personally. We will certainly miss him!

Thanks to Pam Turner for the photos!

Anson received a commemorative plaque, a poem and a pocket knife as presents.

Chinese practicum students work in the vineyards at Mountain Grove

Three groups of students from the Chinese program spent three days working in the vineyards at the State Fruit Experiment Station last week on Tuesday May 31, Thursday June 2 and today Friday June 10. They worked with me recording phenology using the E-L chart. Susanne Howard showed the group how to take grape cuttings for propagation and Shelia Long and her crew – Emma, Rachel, Lisa and Skyler showed the group how to shoot position, sucker the grape trunks and how to train vines. Here are some photos.

The students had to decide which development stage the grapevines had reached.

Raspberries rotated into the high tunnel today

This will be the raspberry projects third year of production. We thinned the shoots in the bagged raspberries earlier (April 13) but did so again when we moved them from the field to the high tunnel. We waited until we saw a few of the primocanes with flowers on them. It looks like thinning the shoots twice before putting them in the tunnel may be necessary after the establishment year. We thinned the canes to 5 per bag (5 per square foot).

Here are the raspberries in the field before moving.

It took about an hour and a half with our crew thinning 4 bags at a time. The shoots we removed were raked up and transported to the compost pile.
