1. Planting: Choose a planting location in full sun or partial shade (4 to 8 hours of sunlight per day). The Thuja ‘Techny’ thrives in loam or sandy loam soil that is well-draining. However, the shrub can tolerate alkaline soil. It also withstands maritime climate conditions.

When planting your Thuja 'Techny', dig a hole that is just as deep as the root ball and twice as wide. If the top of the root ball is lower than the surrounding soil, remove the tree and fill in part of the hole. Replace the tree and fill in the hole with the same soil you removed. You do not need to add anything to the soil. Mulch around the tree with shredded hardwood mulch. A layer three inches thick, extending three feet, around the tree is ideal. Make sure that the mulch isn't piled against the trunk. 

2. Watering: Keep the soil moist but not overly waterlogged around the Thuja ‘Techny’ to encourage growth. During the hotter months, you should water once a week unless you have received any rain. After the summer season, your normal rainfall should be sufficient unless there is an extended period of drought.

3. Fertilizing: The Thuja ‘Techny’ benefits from an annual springtime application of general-purpose, balanced evergreen tree and shrub fertilizer. Follow the instructions on the fertilizer packaging.

4. Pruning: To keep the shrub tidy and help create a hedge, the Thuja ‘Techny’ benefits from shearing in the late winter to early spring months. Generally, the shrub is pruned so that the bottom half of the bush is slightly wider than the top half. Such a bell shape allows sunlight to adequately reach the bottom branches of the conifer and encourages more uniform growth habits.
