The trial consisted of 8 plants of 'Tallgold' compared to 8 plants from the same species Juniperus virginiana, variety 'Skyrocket', with similar growth habit, and 8 plants of Juniperus chinensis, variety 'Golden Pfitzer' with similar foliage colour. Trees of 'Tallgold' were propagated in the spring of 2010 and planted in the ground in 2012. Trees of both 'Skyrocket' and 'Golden Pfitzer' were puchased as potted nursery stock in 2012 and planted in the ground that year. The trees were planted in rows which were 10 metres long. Observations and measurements were taken in 2012 and 2013.
