The Deer Resistant Garden in the Community Education Garden tests plants to identify those less affected by winter deer browsing. Deer are in this area in the winter, not the summer, so the garden focuses on evergreens. The garden was started in May, 2013.  This list of plants is current as of September, 2017.

What we have learned

2017- In early March, with about 10 inches of snow on the ground, evidence of light deer browsing on the the portion of the ‘Otto Luyken’ laurel above the snow line. In the adjacent Entrance Garden, the deer browsed the holly shrubs.  In mid-March, deer rubbed the bark off a section of sumac shrub in the Natives and More garden.

2016- In mid-January, with about a foot of snow on the ground, evidence of heavy deer browsing on the ‘Otto Luyken’ laurels.  In the adjacent Entrance Garden, the deer browsed several holly shrubs.

In mid-May, fresh growth on the laurels shows the plants are recovering well after winter deer browsing. In the adjacent Entrance Garden, the hollies are recovering with fresh growth.

2015 – No evidence of deer browsing until April, when a few nibbles are evident on the 2 smaller of the 3 ‘Otto Luyken’ laurels. These 2 shrubs were planted in 2014 and are about 18″ tall.  Not related to deer browse, a pieris ‘Fire N Ice’ and a hinoki died, both likely due to a warm October, then cold snap in November and the plants were not yet dormant. Both were planted in 2014 and removed in 2015.

2014 – No evidence of deer browsing
