Spray and Grow
I mist my Swedish Ivy daily between waterings. Should I include or use some spray and grow with some of my mistings?
I believe that everyone finds their own best way to take care of their plants. However, you might be interested to know that scientifically speaking, misting doesn't help your plants. Misting only raises the humidity around the plant a few percentage points, and that for only a few minutes. For misting to have any value in raising humidity, it has to be done every 15 minutes.
So if you enjoy misting your plant(s), go ahead, but know that you don't have to do it.
Secondly, for "spray and grow," I presume you mean some kind of foliar fertilizer. I don't think it's of any value to Swedish ivy; introducing unneeded minerals into (or onto) the plant can actually be harmful. Swedish ivy is a very undemanding plant. By far the most important factor in having a healthy plant is testing the soil moisture before watering, to make sure it's not too wet. https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/testing-moisture-in-plants.htm
