Answer: In general terms Witnercreeper euonymous is not an overly demanding plant (it can become invasive in some circumstances) so it should grow quickly once it becomes established, a process which takes a season or two. So I would expect more growth this year. Since there was lava rock in that location, one might also wonder if a long term weed preventive had been used there, or if the soil had become severely compacted. Either of these could possibly limit subsequent growth in that location. To help it along (short of replanting it) you might run some basic soil tests and see if any additional soil amendments might be useful and in what amounts.
