'Green Gem' is more resistant to winter burn than other cultivars, but this will do best in a protected site with hospitable conditions. Remove accumulated snow in the winter time to protect branches. It grows best in well-drained soil in full sun to part shade and requires little pruning. The small leaves of 'Green Gem' do allow it to handle shearing well, though, but be cautious that you never prune before the last spring frost date or tender new growth can suffer damage. Always prune during dormancy of winter months. Plant in soil that is preferrably amended to be less alkali and more basic to slightly acidic. Roots are shallow, so limit cultivation around the base of 'Green Gem' to avoid damaging them. Moderately resistant to boxwood blight. Poorly drained soils may cause root rot. Susceptible to boxwood leaf miner, boxwood psyllid, and boxwood mites.
