Plants should be matched to a container of the right size to ensure that water is distributed efficiently. Plants in containers that are too small can become “root bound,” meaning the roots take up all the space. Plants in containers that are too big may not hold water in the soil and so will become dried out.  If you check the roots and you can tell there is more root than soil, this is a good indication that it’s time to get a bigger pot. You only want to move plants up one pot size at a time so you don’t end up with too much extra room. If the leaves of the plant seem disproportionate in size to the bottom, you should move up a pot size. If the pot has ever tipped over because of being top heavy, this is a definite indication you need a bigger pot. As with many aspects of tending indoor plants, there is no hard and fast rule that always applies. You need to occasionally take stock of your plant and judge if you feel a bigger pot would benefit it. Since overwatering is often what kills plants, pots that allow plants to drain are very important. These pots will either have a hole in the center of the bottom or may have some kind of thin slits on the bottom. Pots with a solid bottom can cause water to pool and the roots can rot if soaked for too long.  If pots without drainage holes are your only option, it works well to put a layer of stones at the bottom of the pot. Extra water can pool there and won’t be in direct contact with the soil and roots. The stone layer should be an inch or so deep. Be extra careful not to overwater your plants. If you can only find plastic pots without holes, you can drill your own holes into the bottom. If your pot is going to drain water, you most definitely don’t want it draining out onto your floors. You can purchase plastic pans specifically for this, or you can improvise and use a plate or saucer. You could even cut up a milk jug or 2 liter bottle if the pot is small enough and you aren’t overly concerned with the appearance of it. Always empty this drainage pan within a...

TL;DR in Indonesian:
Gunakan pot berukuran tepat. Masukkan tanaman ke dalam pot yang memiliki lubang drainase. Letakkan nampan drainase di bawah pot. Pindahkan tanaman ke dalam pot baru jika perlu.
