The enchanting Blue Poppy (Meconopsis)

In the fall an organic mulch can be applied to a depth of 2 to 3 inches. Be sure to wait until the plants are completely dormant to apply the mulch. Fall is a good time to plant Meconopsis but they must be planted early enough in the fall so they are growing strongly before going dormant. If you miss this window of opportunity, then plant them in the spring.
