Q.Why doesn’t my Clematis grow tall?
I have a Clematis fuji musume, which I have had for 2 years. It grows no more than 2 feet and has a couple of nice blue flowers. I train it again a wall using a trellis. How can I get it to grow tall? Thanks

There are several factors that will be at play here. The first is the variety.
This is known for being a more compact growing clematis. In fact, this is the focal selling point for this cultivar! Now, over time, and with maturity, they will reach a height of about 8 feet tall if they are trellised properly. Depending on how cold it gets in your area, this can have something to do with it as well.
There are a few things that all clematis need to be healthy, and they will have different pruning requirements as well.
