Now that's a score!

Jades can be pruned any time, however there are a few things to keep in mind.
If you prune in the Winter or early Spring, the growth that results may be more
spindly and etoliated. If you prune during the Summer or Fall, when light is abundant,
the growth will be more compact and sturdy. But, again, Jades can be pruned any time...
I just prefer that tight, sturdy, colorful re-growth.

Second thing to consider is acclimating your plant. If it has been indoors, spend two weeks
transitioning the Jade from bright shade to full sun. After pruning, set the Jade in a bright
but not full sun location. Wait to water until you see new growth erupting from the nodes.

As far as pruning goes...start by removing any drooping, downward angling branches.
Once that's done, consider which main branches you want to keep, then remove the rest.
Jade branches have rings called nodes. The segment of branch between those rings
is called the internode. When you prune, you will cut through the internode - but leave
a 1/4 inch stub of the internode, which will dry up and fall off naturally, allowing the
nearest node to form a callus.
