Beginner Gardening: Brown patches on Epipremnum. Any thoughts?, 1 by Metrosideros

Epipremnum pinnatum is a very tough tropical plant. Here it is a weed. It is not very particular to soil, as it is a hemiepiphyte; so your soil & bark choices are of little consequence. The more root-space you give it will allow a larger plant though.

By giving the plant a high nitrogen fertilizer, will be good for the leaves, but not the stems, which is how this plant carries itself.

Treating tropical plants the same as temperate annuals will be a mistake.
High nitrogen is good for Aroids such as Colocasia & Alocasia as their main growth is in leaves., but it won't be good for Epipremnum.

Climbers & vines such as Epipremnum & Philodendron need much more potassium than your normal temperate plant. This is the case with many tropicals that require strong stem growth. You will see the deficiency show up in the leaves, which may be the case with your plant.

A good article about potassium nutrition is found in Broschat & Meerow. 2000. "Ornamental Palm Horticulture". University Press of Florida. Look up Chapter 4 "Mineral Nutrition of Ornamental Palms".

Giving all plants a high nitrogen diet in general is wrong. If you do that to tomatoes and peppers, you won't get anything but leaves!

It is best to care for plants on an individual basis, rather than treat them all the same.
