It was a month ago that we first visited the Riverfront, the intriguing new Napa development nearing completion on Main Street. The mixed-use Riverfront combines retail space on the street level with condominiums above it.

Here we are, already, at the longest day of the year. The spring rush of growth in trees and the garden has subsided. The first flush of roses has faded and the first flush of growth is maturing in the trees. Little apples are scattered on the ground under my tree — the annual event known as “June drop” when fruit trees naturally adjust the load they are able to carry.

Facing a second year of drought, Napa Valley gardeners have to make some tough decisions about what to water. All plants need water, even cactus and succulents. If you have to ration water, give priority to your biggest investments.
