Is the root ball of your houseplant congested (does it show through the base of the pot or is it visible on the soil surface)?
Is the soil in a pot drying out more quickly than it used to?
Has the growth rate noticeably slowed down?
Has the plant become overcrowded due to the growing outsets?
Has the top growth of your plant become lopsided?
Have the roots of your plants been attacked by pests or diseases?
Was the plant newly acquired?
Congested root ball is a clear sign that your plant has outgrown its pot. You should repot your plant using a new flowerpot that is at least 1 inch wider and deeper than the old one.
This means that there are too many roots and too little soil in the pot. You should repot your plant using a new flowerpot that is at least 1 inch wider and deeper than the old one.
Slowed growth shows that the plant isn't getting enough nutrients from the soil, so more soil is needed. You should repot your plant using a new flowerpot that is at least 1 inch wider and deeper than the old one.
Overcrowded plants will need more room and soil to get enough nutrients and water. You can repot your plant into a bigger flowerpot but it is not necessary, you can also divide and propagate offsets. That way you would get new separate plants.
Lopsided top growth is a sign that the plant has overgrown its pot. Repot it using a larger flowerpot and put your plant right in the center of the flowerpot.
If the roots have been attacked by pests or diseases - you'll want to change its pot. Before replanting, make sure to prune off any damaged or diseased roots, and to spray off any insects from them. If the roots have been affected by fungus, spray roots with fungicide.
If you just bought the plant, chances are it came in a temporary plastic container or a small flowerpot. Repot it using a slightly bigger flowerpot.
If you have been repotting or changing plants soil annually every spring, you should continue doing so.

Sreten null
Hi! I’m Sreten Filipović. I graduated from the Faculty of Agriculture at the University of Belgrade, with a master's degree in Environmental Protection in Agricultural Systems. I’ve worked as a researcher at Finland's Natural Resources Institute (LUKE) on a project aimed at adapting south-western Finland to drought episodes. I founded a consulting agency in the field of environment and agriculture to help farmers who want to implement the principles of sustainability on their farms. I’m also a founding member of the nonprofit organization Ecogenesis from Belgrade whose main goal is non-formal education on the environment and ecology. In my spare time, I like to write blog posts about sustainability, the environment, animal farming, horticulture, and plant protection. I’ve also published several science-fiction short stories.
