Horticultural Interests
All the areas on the Exposition site were composed of drifting sands or sands that had been pumped in from the bay, upon which no ornamental plant could grow.
It was necessary to bring down from the Sacramento Valley rich soil (fifty thousand cubic yards), and spread sixteen thousand cubic yards of fertilizer over that, in order to maintain lawns, trees and shrubs.
An immense number of trees, ranging from thirty to sixty feet in height, were moved from Golden Gate Park and the Presidio of San Francisco. It is the largest number of evergreen trees ever moved in connection with any landscape work.
Many plantings will be made thruout the Exposition. It will require the moving of four hundred thousand plants each time a change is made.
