My clematis is 2 years old now and is spindly and exactly the same height as last year-?

Question:Is there anything I can do to make it fuller? It has never flowered, is in a great spot- sunny, mulched roots, I fed it miracid and fertilized. Is it possible to crowd it? I have 4 plants on a 3 ft wide trellis. Thanks!

Answers:
The old saying about clematis growth is, "The first year they sleep, the second year they creep and the third year they leap." Growth may seem slow as the plant builds its root system, but once established, clematis are strong growers.
