I have never had a Salvia plant. Some are looking bushy. Which part of the plant do I cut/trim (from top or bottom) and how much?
Our salvias have become woody and brittle with few flowers. They bloomed nicely when first planted about 3 years ago and were cut back to about 50% when the blooms were done. However, they have never returned to their prior condition, and blooms are skimpy. They seemed to improve only a bit when fertilized with Grow Power.
Keeping the plant dead headed or trimming the plant back by 1/3 after blooming will help the plant.
Make sure the soil is drying slightly between waterings.
Using a slow release fertilizer in the spring will help the plants through the bloom season. Over fertilizing can lead to lots of leaves and no flowers.

I transplanted this plant from a friend's garden and it's flourishing well but I have no idea what it is!
Since salvia is a perennial, will it grow in Alaska? I live on the Kenai Peninsula.
Salvia hardiness is zones 5 - 9.

I have red salvias. They looked beautiful until the last week. They were bright red and now they are faded and almost look dead. I have been watering. They really make my flower bed look bad. I am considering replacing with another flower if they don't start looking better. Do you have any tips? Thank you, Diane Hamric
It may be possible that while you are watering, the water is not penetrating into the rootball of the plants. Often, potting soil will actually repel water if it is allowed to dry out too much. So, first I would recommend trying to give the plants a really good and deep watering to force the potting soil to start to absorb water again.
The other possibility is that the plants have a fungus, like powdery mildew. You can treat for that and the plants will eventually recover. But it could be weeks before they do so and it might just be easier to replace the plants.
Here is some information that may help you:

We planted new beds in sun with salvia; however, the bottoms of the plants are drying out and the purple blossoms are beginning to fade. They receive water from an irrigation system. Any ideas? Will they come back and be green and bloom again?
Once established your Salvia plants can dry out slightly between waterings, but when first planted they will need extra watering until their roots become established.
It sounds like the plants were stressed and though you have some die off of the plant. Keep up the care of the plants and they should recover over time. They may look a bit tough this year, and next season you will have a nicer show of plants and flowers.
You can dead head any spent or dead plant material.

I just bought 2 lovely Cerinthe purpuranscens and potted them yesterday. This morning they were thriving. I just looked at them and they are wilting! They are in full sun right now and we are having a heat wave. Any suggestions as to what I can do to save them?
Potted plants will need extra water when summer temperatures rise above 85 degrees.
Extra watering and even sheltering them from the hottest part of the day will help your new plants adjust.
Here is a link about the care requirements.
