Obsession Nandina performs best in sites that provide well-drained soil and anywhere from full sun to mostly shade. I use it under large shade trees, as a natural hedge, as a foundation plant or around air conditioning units as a screen.

To plant, dig a hole no deeper than the root ball and two to three times the width of the root ball and fill it with water. If the hole drains within a few hours, you have good drainage. If the water is still standing 12 hours later, improve the drainage in your bed, perhaps by establishing a raised bed. Turn and break up the soil removed from the planting hole. Mix some organic compost if the native soil is clay or compacted soil. Remove your plant from its container and carefully but firmly loosen the root ball. Set the plant into the hole you've prepared, making sure the top of the root ball is slightly above the soil level. Pull your backfill soil mixture around the root ball in the hole, tamping as you go to remove air pockets. Then water thoroughly and cover with a one to two-inch layer of mulch

I've seen no serious problems with pests or diseases on Obsession Nandina. Wet or consistently moist soil can be a killer. Plant in well drained soil.

Obsession Nandina requires little if any pruning, only to remove a stray or broken branch.

no pruning needed, just cut away dead or broken branches or stray ones.

Fertilize Obsession Nandina in early spring when new growth begins to emerge with a well-balanced shrub fertilizer or an organic or natural plant food.

Unlike other similar nandina cultivars that display red foliage only during the cool season, Obsession is a very attractive nandina that displays dark red new growth throughout both the warm and cool seasons.
