I've planted 4 different kinds of clematis vines in 3 different planters and NONE have performed well. On all of them the leaves end up going brown and falling off. Usually it happens one strand of vine at a time. In the past 5 weeks there has been no new growth on any of them. The roots are shaded, the leaves get 6+ hours of light and I've been carefully monitoring the soil moisture. I also fed them after planting. Other types of plants in the same containers are thriving and doing well. Please help!
It does look like you may have a fungus, so I would recommend that you treat it with a fungicide.
That being said, they also look like they are not getting enough sunlight. Not all sunlight is created equal. These plants need at least 5 hours of really bright sunlight to do well. If they are getting filtered or indirect sunlight, it will not be enough for the plants to grow and thrive.
Leaves have turned brown on many of my garden plants, especially my clematis and lilac trees. Do I treat the soil or the plants themselves?

I would also suggest talking with your County Extension Office. They can help you with a soil test and can look at leaf samples for you.
My clematis has bloomed. My question is should I dead head. Will it bloom again this season?
You should first of all find out the name of the clematis and then which pruning group it belongs to. There are three, and it is important that you treat the plant according to the group it falls in to. Some plants which flower early - say before June - can be trimmed back and with luck you may get a second late summer flowering. Find the pruning group before you do anything else.

My 3-yr old clematis vine was full of beautiful large blooms (blue 6-7 petals) early to mid spring, then died back. Now it has new growth and blooms. I remember something similar last year. Any ideas?
Clematis fall into 3 groups, mainly for pruning. If it flowers before June as yours has, you should (have) pruned it after flowering. Enjoy the second flowering but to maintain the shape you should trim back after next year's flowering.
now that my butterfly weed plants have beautifully covered the planting bed I am wondering if it is alright to remove the seed pods as I do not have room for more plants popping up. I have and older clematis that blooms in spring and occasionally a bloom or two in summer it is getting unruly if cut back down to about 18" will it do harm?
Yes, you can dead head the spent flowers.
