Q.Foxtail Lilies
Bought three foxtail lilies with my autumn bulbs have a very healthy tuberous root system…..deep planting in root free(from other plants) sun I assume; mulch heavy compost or feed roots at planting…….I know they grow tall but could three root systems be planted in a group?

As long as you have a large enough container so that you don't have to replant them every few weeks, say a 10 gallon or so, then group planting can be just fine in a group of three or less.
