When to plant toad lily bulbs (rhizomes): Planting can be spring or summer in hardiness zone 4-9, in hardiness zone 10a spring to autumn but if the summer is too much hot not in the summer
How to plant: Planting in bigger hole than the root ball or the rhizomes, at least 200% bigger, put in the hole back part of the soil with organic matter, dead leaves, hummus and compost, put the tree and cover lightly but enough to hold itself and cover with mulch and a lot of dead leaves.
