Insects, caterpillars, loss of variegation, yellowing of leaves are some of the common issues with Money Plant/Pothos. Keep watch over the plant always and remove any pests you may find. You may also apply organic pesticides such neem water, soap water or garlic solution to the plant to get rid of the pests. Drying of leaves can be another common issue that you could find with Money Plant/ Pothos. Excess direct sunlight could be the reason for this. To prevent this, you may place the plant to another location where it gets not so bright but filtered sunlight. For loss of variegation, it can be a sign that the plant needs more sunlight. Also, if you find the variegated plant leaf fading in color, bright sunlight could be the reason for this. In such a condition, you will have to move the plant to a shadier place. Yellowing of leaves indicates overwatering. Hence always remember to water the plant after the soil is completely dried off.  Also, check the drainage holes of the pot are not blocked to trap the water inside, resulting in the plant to ‘sit’ in the water.
