However, you might not have that much space when placing them in the containers. No worries, you can get away with lesser spacing in the containers if you don’t plan them to be a permanent display.

You should also ensure that the bulbs are not touching each other. Plant place them at least a bulb width apart when planting them in the tub. When growing these plants in a container, you should use the bulbs in a bulb lasagne with other bulbs.

Another important thing is to remember that when you want to create a bulb lasagne, make sure not to place them directly above the ones in the lower tiers.
