We have been running a series of Christmas tree planting workshops to encourage everyone to grow their own Christmas tree instead of buying and disposing of a tree each year. We use Norway Spruce, a traditional choice for Christmas tree, and recommend you plant them in a pot (unless you have a large garden) as Norway Spruce can grow 7 metres tall and 4 metres across if planted in the ground.
If you plant your tree in a large pot (at least 10-15 litres in volume) the tree will grow to approx 120cm tall. The larger the pot the larger your tree will grow. You can then choose to bring the tree inside each year to decorate for Christmas, or decorate it outside. You can care for your tree by adding organic material throughout the year, for example, seaweed, which will add nutrients to the soil in the pot.
