Beginner Gardening: my Swedish Ivy isn't happy, 1 by Plants4myPots

Hi!
I've had this little Swedish Ivy plant for about a year, and it doesn't seem to be very happy. I thought I'd have a big bushy plant that I'd actually have to trim to keep cute - but it's been performing pretty poorly.

I took this picture the day before yesterday. It doesn't seem totally unhealthy - but it just doesn't seem to grow. It's looked like this for at least six months. It's only about 4" tall, leggy with a few decent looking leaves.

It's potted in regular potting mix, probably Miracle Grow or Jungle Growth. I added the bit of sphagum moss the other day on a whim. I haven't really added any fertilizer either. It drains really well and I water it about twice a week.

It's on the back porch of my house here in Central Florida - where our summers get pretty hot, and I don't live far from the beach, so there's a lot of salt in the air. The weather's cooled off a bit now. It gets probably 1-3 hours of direct-ish morning sun. By afternoon, the sun's moved enough that the sun-loving plants on the shelf above it block the harsher sun.

Any suggestions to get this plant going?

Thanks!
