ABout five years ago I planted maybe 150 1 gallon size Pt Reyes manzanita on a 
rocky hillside, hoping for an attractive ground cover. The plants have grown long 
branches, 3-6', that drape down the hillside. But at a glance it still looks 
barren because the branches have such a low density of leaves. I am seeking advice 
as to whether they need help or will succeed on their own, or if I need to do 
something different.

There is a sprinkler system that waters the hillside lightly every day and more 
heavily once a week. Once a year I put some granulated fertilzer near the base of 
ech plant. A soil test describes the soil as pretty much devoid of organic 
material and low in nitrogen. However, vinca will root and grow in the same area 
though it is always a bit yellow.
