Monthly 20/20/20/ is fine.

There was a story in the paper about a guy buying 2 small pots of clematis.Both were the same kind,same size,same price.He planted one on each side of the front door.Every morning for years he sat on his front porch drinking his coffee with cream and sugar while reading the paper.
By time he finished the paper his coffee was cold and he always poured out the cold coffee with cream and sugar in the same spot which was the bottom of the one clematis.
Over the years the one clematis grew just fine,the "coffee"clematis grew like crazy.Up the lattice,along the rain gutters,up the power line,along the power line to the neighbors house.

It won't bloom! Why does my clematis not flower?
There are three main reasons why a clematis doesn't flower: 1) The plant is still immature and hasn't reached flowering size yet. Clematis will take up to three to five years to become a fully mature plant, but they should carry a small number of flowers even while still young.
2) The most common problem with vines that produce an over abundance of green growth and no flowers is caused by a nutrient imbalance, usually too much nitrogen. It is best to fertilize clematis with organic, slow release fertilizers when you prune group three clematis (see Pruning FAQ for a full explanation of prune groups), usually in late February or early March. Fertilizers are characterized by 3 numbers representing the relative concentrations of nitrogen, phosphorus and potassium (N-P-K), in that order. Plants use nitrogen to grow foliage, phosphorus to develop root systems and form fruit, and potassium to promote flowers and develop resistance to disease. Choose a fertilizer with a low nitrogen number relative to the phosphorus number, such as 5-10-10, so that your plant will develop blossoms and roots, rather than lots of foliage. Some bulb or tomato fertilizers have concentrations similar to this. A second dose of fertilizer is recommended in June. Encapsulated three month slow release fertilizers are also a good choice. 3) Untimely pruning can also result in the loss of flowers, especially with the early flowered cultivars (these types include C. alpina, C. macropetela, and early large flowered hydrid types). These types of clematis form their flowers on the previous years growth. If pruning removes this new growth, the plant will not flower. Please also see the Pruning FAQ to get a better understaning of pruning requirements and how this affects flowering.

For the most part all versions of Clematis are heavy feeders but all purpose 10-10-10 will be fine applied once a month. Many experts recommend keeping nitrogen down for the first feeding of spring so a 5-10-10 would be enough to promote healthy growth and flowers. If you have any doubts a soil test will tell you if anything is missing that you may need to supplement with, this may help decide if you need to add lime to keep soil neutral.
