In each pot plant the bottom layer of bulbs (Tulips) on 5cm of compost so they are approximately 15-18 cm from the top (pointy ends upwards). Intersperse the different bulbs and ensure they are not touching.
Cover with 5cm of compost before planting the next layer (Narcissi) in the same way approximately 10-12cm from the top don’t worry if the bulbs are sitting over the lower layer of bulbs, they will find a way through.
Cover with 5cm of compost before planting the final layer (Crocus) 5-8cm from the finished soil level.
Finally cover with compost and leave outside over winter and wait till spring.
Place the pot on feet so it can drain to prevent the bulbs from rotting or move undercover so they don’t get too wet.
