My flowers on Calibrachoa are very leggy and seem to be dying from the roots. Should they be cut way back?
These plants do benefit from getting a bit of a trim a few times during the summer. Normally, you should take off 1/3 - 1/2 of the plant if you start to notice it getting leggy. This will force them to bush out again, though you will lose blooming for a week or two. I normally trim mine right before I leave for vacation. That way I don't see the plants looking bare and by the time I get back, they are starting to bloom again.
What would cause the leaves of my Calibrachoa bells to curl?
There are many reasons why leaves may curl - disease; insects; water, light or temperature stress - but the first line of defense always remains the same - good culture to create strong plants. This article will give you a checklist for your million bells: https://www.gardeningknowhow.com/ornamental/flowers/million-bells/calibrachoa-million-bells.htm
If you can't come to any conclusions, you could send us some pictures, or you could take some plant samples to the extension service (assuming you're in the US) where they will be able to diagnose problems. This link will help you find the nearest office:

Calibrachoa leaves drying up. Appears to have a very fine mesh type web on leaves. Rust colored flowers are becoming mottled.
It is likely spider mites, which can be treated with neem oil. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
I have 3 Calibrachoa hanging baskets. When I bought them, they were full of blooms and vibrant. Now they look like they are dying. The foliage has a dried up looking and only a few blooms. I water and fertilize them according to their specifications. My baskets did the same thing last year. I cut all the dead looking off and they do eventually bud back out and bloom later. What am I doing wrong?
You are likely not watering enough. This is common for outdoor container plants. They need to be watered at least once a day, 2X a day if the temps are above 85F. Also, if the basket's soil dries out completely, it will start to repel water. You will need to set the whole basket into a bucket of water for 20 minutes or so to fully rehydrate it so that it starts absorbing water again.
I have a Mini-Famous Dark Blue Calibrachoa that was blooming well. The last couple of weeks it doesn't bloom at all, just have the green leaves hanging down.
If they're in a container or hanging basket, they normally require additional fertilizer. That said, the nitrogen content may be higher than it should which can limit the flowering. Phosphorus can help offset this. I would recommend adding a bit of bone meal to encourage more blooms.

I have a calibrachoa hanging plant. Will it come back next year and, if so, how do I care for it in the winter? I live in Montana. I am kinda new to gardening, so any help would be appreciated. Thanks Jeanne
In cold climates a Calibrachoa is grown as an annual plant.
It will not winter over in your climate and growing zone.
