I got these two Arrowhead plants from work about 3 years ago. They love their location in the South window, however they hang high and don’t get a full dose of good ‘ol sol. They don’t mind less light either.
These are relatives of the Philodendron, another easy plant to grow. They like moist soils, but don’t over-soak them. They like a light 10-10-10 fertilizer.
Pruning is a bit tricky. You don’t want to cut all the way down to the split or you will nip the tip of the new leaf off. As you look at the stem that branches off, you will notice there is a bulge in the stem, this is where the next leaf is curled up in it’s stem.

These guys can get spider mites. These don’t get moved outside during the summer, so they’ve been insect free.
The plant will start to shoot ‘runners’ (l o n g branches) after a few years. If you like them, keep them. I’ve got one that is about 15 feet long. I just want to see how long it will actually get! To keep the plant bushy, these should be pruned off. If you do this during the summer months, place the piece, now known as a ‘cutting’, into water and it should soon root, then plant it in a light mix.
This is the start of a runner. See the thick ends of the leaf stem at the main branch? Don’t cut below this.
After it grows out, the brown dried-up stem can be cut, do not peel it!
