Changing the orientation of a tree

Question

Please, The code for the following tree is at:

TikZ tree sibling distance

However, I want it to grow to the right as shown in the figure below. Please, help on this. Thank you. Best regards.

Here is the code as refereed above:

\usepackage{geometry}
\usepackage{forest}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usetikzlibrary{shadows}
\begin{document}
    \tikzset{
        my node style/.style={
            font=\small,
            top color=white,
            bottom color=blue!25,
            rectangle,
            rounded corners,
            minimum size=6mm,
            draw=blue!75,
            very thick,
            drop shadow,
            align=center,
        }
    }
    \forestset{
        my tree style/.style={
            for tree={
                parent anchor=south,
                child anchor=north,
                l sep+=5pt,
                my node style,
                edge={draw=blue!50, thick},
                edge path={
                    \noexpand\path [draw, \forestoption{edge}] (!u.parent anchor) -- +(0,-7.5pt) -| (.child anchor)\forestoption{edge label};
                },
                if n children=3{
                    for children={
                        if n=2{calign with current}{}
                    }
                }{},
                delay={if content={}{shape=coordinate}{}}
            }

I left fine tuning of children's centering/positioning to you.
