Tulip bulbs can be removed from the fridge and planted out in the garden now. Gardeners in cooler areas don’t actually need to worry about chilling their bulbs, but those in warmer areas will get a better result after a period of chilling.
Plant bulbs about 10cm deep, or twice the depth of the height of the bulb (eg, if bulbs measure 5cm high, plant them 10cm deep). In warm areas you can plant as deep as 20cm, where the soil will be cooler. Plant in a sunny position in deep, rich, well-drained soil. Add slow-release fertiliser to the soil when planting.
