The best potted Christmas trees are grown "pot-in-pot". This technology guarantees a healthy and vigorous root system, where the roots remain inside the pot.
- During their lifetime at the nursery, pot-grown trees are transplanted several times into bigger pots in order for their root systems to develop.
- During the growing season, the trees are graded and pruned into shape, and needle samples are taken to check the health of nursery crops.
- Manual quality control is performed several times a year.
All Nordmann fir pot-grown trees are GLOBALG.A.P. (Good Agricultural Practice) and MRS-certified.
