When to repot a Pothos

When should a pothos plant be repotted? I have a large pothos plant, probably 15 ft. vines, and I can barely put a finger into the soil because the roots are so thick. I was wondering if it would be beneficial to repot the plant. The plant remains strictly indoors at all times. When I repot, would it be beneficial to loosen the soil/replace with new soil? I have had this plant for about 5 years and have always top watered. Would this be a problem for the plant? I have read that this can be problematic. Can anyone provide an inexperienced planter with some advice? I greatly appreciate the help.

When should a pothos plant be repotted? Whenever growth is adversely affected because of root-bound conditions, or there is evidence that the soil has failed structurally. These conditions will be evidenced by dying leaves and/or a general slowing of stem extension or a reluctance to extend at all. I have a large pothos plant, probably 15 ft. vines, and I can barely put a finger into the soil because the roots are so thick. I was wondering if it would be beneficial to repot the plant. Yes, of course it would. The plant remains strictly indoors at all times. When I repot, would it be beneficial to loosen the soil/replace with new soil? Remove the root mass & cut the bottom 1/3 of roots off the plant. Then, with a sharp knife or garden scissors, remove another 10-20% of roots around the perimeter of the root mass. Additionally, you can make several vertical scores in the root mass. Remove loose soil & add new as you return to same container, or pot up a size if using a bagged soil. I have had this plant for about 5 years and have always top watered. Would this be a problem for the plant? No. Top watering is superior to wick or bottom watering in that it helps flush accumulating metal/fertilizer salts from the soil, where wick watering does the opposite. You shouled always make sure you're growing in a soil that insures you can water this copiously w/o risking root rot issues from extended periods of saturated soil. I have read that this can be problematic. I would disregard what you read. Sorry, but you'll find much unfounded, anecdotal advice w/o scientific support floating around. Can anyone provide an inexperienced planter with some advice? No. ;o) I greatly appreciate the help.
