How to revive a dying pansy plant

http://www.gardenguides.com/83077-revive-pansies.html

Cut it back. Depending upon the part of the country you are in it may be too hot for the pansies now. Being perennials they should revive.

Examine the pansy, removing any dead, dendritic foliage. Trim back no more than 1/3 volume. Making sure soil conditions are neither soggy nor dry. To help promote foliage growth and overall plant health utilize fertilizer with a higher nitrogen level. For blooms utilize fertilizer with higher potassium. Also Neem oil to rid pests, or a multipurpose product such as Garden Safe Fungicide3- fungicide, insecticide, miticide to rid other plausible causes of ailment.

I have brought back many plants by finding a spot where they will be out of the way, more shaded to decrease the stress and water only when they were pretty dry. Out of the wind and weather they are able to recover without stress and surprisingly they came back as a healthy plant. I then started getting the plant used to the sun and weather in short increments, and by that time it was back to a much more healthy state and ready to be put back where it belonged.

Thanks for the help.

Nancy is right on - trim it back by half, then put it in the coolest spot you have, and be gentle - it should perk up when things are not so hot.

I would guess it is lacking food. Get some grow sticks and insert into soil. If has been potted for long time, it may need to be repotted with fresh potting soil.
