I was given a container with four to five ivy plants---have had them for almost two years. They have been healthy until this May when three plants suddenly began to yellow and dry up. i have never overwatered but added some when the soil felt dry. I have not fertilized the plants to that point. In May as I said they began to die off. I moved them to a brighter area since they were in a shaded window inside. I removed the dead plants (all are about 5 inches tall) and repotted to another container with the same soil. I fed them with a nitrogen-rich fertilizer and placed the pot back in the bright window (5-6 hours of sun daily). It seems to have no pests and leaves were clean. It has now been two weeks and it appears one of the plants is beginning to yellow. Can you suggest the direction I should go with the container of ivy now. (I have Miracle=Gro fertilizer or fish emulsion available as well as new potting soil.) thank you
Indoor Ivy are very susceptible to Spider Mites; especially during the dry winter months. You can mist the plants during these dry periods. I have even used Neem Oil a regular bases during this time to keep these pests from taking over and killing Ivy.
Neem Oil is organic and safe for people and pets.

can I use either Apple Cider Vinegar or Baking Soda as a fertilizer on and English Ivy?
English Ivy rarely need fertilizing.
If you do need to fertilize, use a fertilize with high nitrogen for the green leaves.
I would not recommend vinegar or baking soda.
If you grow English Ivy indoors, does it need a trellis or something to grow on or does it just go "wherever" it wants ... Which brings me to ask also, how fast does it grow? Thank you.
Yes, it does tend to cling to just about anything. It won't seem like it is doing much for the first year. You will start noticing it completely take off after the third year.

I have my English Ivy in an old glass jug and it's starting to grow algae in the rocks. Can I put a ghost shrimp or critter of some sort to eat the algae but not the plant? I know I will need to trim the roots and clean the algae.
I thought maybe I overwatered it so I repotted it.
I have answered many questions on indoor Ivy plants, so your not alone! They can actually be quite finicky.

Is this normal or due to some specific factor.
What you describe is a possible nutrient deficiency. Water adequately and fertilize with a complete organic fertilizer like this:

When is the best time to prune english ivy? What is the best method for pruning the ivy? I also have a section of ground where I want to regrow some english ivy. What are some tips to promoting new growth?
English ivy can be pruned any time of year and should be removed from trees and walls as soon as possible. Propagating is easiest to do when the ivy is actively growing in spring and summer. Here are the details: https://www.gardeningknowhow.com/houseplants/ivy/ivy-plant-propagation.htm
