Forest - how to make nodes grow in separate directions

Question

MWE:

\documentclass{article}
\usepackage{tikz}
\usepackage[edges]{forest}

\newcommand{\nodecircle}{circle,fill,outer sep=0,inner sep=1pt}

\begin{document}

    \begin{forest}
        [,\nodecircle, alias = I, s sep=0.4cm,l sep=2cm,
        [Rain]
        [Shine]
        ] 
        \node[above] at (I){Nature}; 
    \end{forest}

\end{document}

This produces a forest with two nodes, growing downwards.

I know that to change the direction in which it grows, I have to use the grow = option command.

However, how do I make both child nodes grow in separate directions?

Specifically, I want the first child node to grow east, and the second to grow west.

However, how do I grow in two different directions from the same parent node? Specifically, I want the Rain node to be horizontally to the right (i.e east) and the Shine node to be west.

This question provides an answer which even the person who answered deemed not elegant. I was wondering if there is a newer way to do it.

Answer 1

This code works (based off Method 1 here):

\documentclass{article}
\usepackage{tikz}
\usepackage[edges]{forest}

\newcommand{\nodecircle}{circle,fill,outer sep=0,inner sep=1pt}

\begin{document}

\begin{forest}
    [,\nodecircle, alias = I, l sep=2cm, grow = east
    [,\nodecircle, before computing xy={l=3cm,s=0cm}, alias = rain]
    [,\nodecircle, before computing xy={l=-3cm,s=0cm}, alias = shine]
    ] 
    \node[above] at (I){Nature}; 
    \node[above] at (rain){Rain}; 
    \node[above] at (shine){Shine}; 
\end{forest}

\end{document}

More elegant solutions are very welcome.
