Our Norway Spruce trees come in pots with enough ample space for the first 12 months. Once these 12 months have passed, we recommend you repot your Christmas tree at the beginning of spring into a bigger pot (which is at least 10 cm larger in diameter than the previous one). For the soil use a multipurpose potting compost and around 10% garden bark mulch, for drainage. Once it becomes warmer during spring, begin feeding your tree liquid fertilizer weekly throughout the entire growing season. Keep it well water and do not allow it to dry.
