Cypress, a conifer, is easy to grow in containers. In fact, those cute little Christmas trees that you can pick up at the supermarket during the holidays are sometimes small cypress trees. While cypress trees can grow quite large when planted in the ground, planting cypress in a pot will limit its growth.
Grow your potted cypress tree in well draining, sandy/loamy soil. To amend soil, use peat, up to a 50 percent mixture. Place the tree in an area that receives morning sun and light shade in the afternoon.
Water your potted cypress tree deeply, and keep the soil moist. A good rule of thumb is to feel the soil. When it is dry to within one inch of the top of the soil, it is time to water. If your potted cypress is growing outdoors, water only in the morning, as an evening watering will cause the roots to get too cold.
Prune your potted cypress tree carefully. Different varieties of cypress have different pruning needs. Generally, don't cut into any leafless areas of a branch and trim branches to their point of origin.
Generally pest and disease resistant, cypress trees are subject to canker, a disease cause by a fungus. Treatment involves removing any affected twigs and branches.
