    Conditions for Growth

    The tree excels in the loam soil of the Riverside Grove, grown in full sun with intense heat (an good irrigation) during the summer and cold nights during the winter.

    Growth Rate and Size

    The trunk grows vertically at just 5-6 inches per year for the first 10 years as the trunk fills into its massive girth, after which the trunk will grow at a faster pace eventually reaching 50 feet. The leaf is a different story, reaching a massive scale quickly relative to its stout young stem.
