Maintenance- Design- Planting Tips

'Emerald Carpet' is a slow growing California native manzanita from the coast of Mendocino County. It is a very attractive plant with dark glossy leaves, reddish stems and small flowers in the early spring. We have mixed feelings about 'Emerald Carpet'. Although it has not died, it has not thrived either. We suspect that it needs more water than most manzanitas. It is in a part of the garden that gets no water. Some Santa Clara Master Gardeners have had success using the cultivar 'Carmel Sur' as a ground cover in low water landscapes.

There are many, many different cultivars of manzanita ranging from ground covers to small trees. Manzanitas are a good wildlife plant and typically tough as nails. They do well in very dry situations. Most manzanitas need superb drainage or they will struggle and die. Plant on a mound or slope and water weekly for the first summer and less after that. By the third summer, stop watering. Avoid fertilizing the plant.

These plants rarely need pruning. Remove the odd branch that dies back in the late summer and the plant will fill in. Some gardeners will remove the lower branches on some of the larger manzanitas to highlight the interesting branching structure and reddish bark.
