Pick a Planter
When I'm picking a planter, I always consider the following features:
Size: If my plant is rootbound, I size up 2-3 inches. I don't want to size up too much more because then it'll have more soil, which will stay wet longer, putting the plant at risk of root rot. Tip: if your plant collection seems to be growing exponentially, it wouldn’t be the most outrageous thing to carry a small tape measurer on your keychain to know if you should buy a pot or not. This might save you many returns (which we all know are terrible b/c it takes up time and then you’re tempted to buy more).
Height: If my plant has longer stems, then I typically place it in a taller pot. If my plant has many leaves at the bottom (it's more bush-like, then tree-like), I try to find a pot with a height that just barely covers the top of the soil.
Color: This is all personal preference, but I always consider the color of the plant’s leaves and how it might complement/clash with the color of the pot. See below pics for 1 plant, styled 4 different ways! The pot makes a difference! Personally, (no surprise here), I have become most fond of earthy and neutral colored pots (black, white, beige, terracotta). When the pot has different materials(e.g. copper or concrete) or comes with a plant stand made of a different medium (e.g. wood or metal), well...it feels like I just hit the jackpot (:
Drainage: Plants need drainage holes so that the soil does not stay moist for too long, eventually causing root rot. Now you’re wondering, “What if the pot is really cute but it doesn’t have a hole?!” Don’t worry, I have plenty of those. I just keep my plant in a plastic pot with drainage holes and then place it into the cuter pot. It does mean you have to take it out to water the plant, but let’s be honest, it’s totally worth it! Below are pictures of the plastic pot it sits in, within its more aesthetic pot which has no holes.
