Planting an evergreen in a pot is especially easy when you use dwarf conifers due to their small size and tidy growing habit. Dwarf conifers are wonderful alternatives to full-sized trees, and they are genetically programmed to grow slowly and stay small.
Specialty conifers commonly sold in our area that work well in containers include dwarf Alberta Spruce, Compact White Fir, Hinoki Cypress, Dwarf Balsam Fir, and Dwarf Blue Alpine Fir.
Give them consistent water and try to keep them from drying out completely and they should perform well year-round.
