Choosing the Right Pot
Spring is a great time to re-pot houseplants in fresh soil, and upgrade a pot size if your plant is root-bound. You want your soil to mimic your plant’s natural environment in order for it to thrive; which is easy to research your plant’s ideal conditions using the internet and plant identification and care apps.
Unsure of what size pot to pick?
As a general rule of thumb, you only want to move up one pot size, and only if it has outgrown its current pot. A good look at how tightly the roots are inside the pot will let you know if you need to move up a size. A plant that is placed into a pot that’s too large will cause most of its energy to go into growing and expanding the root system, and not towards foliage or flowers.
Holes or no holes?
Some pots have drainage holes and some do not. Many interior pots do not have holes, which of course your delicate furniture appreciates. However, no drainage can be troublesome for plants when roots sit in water.
There are several ways to raise happy plants in pots without holes. The optimal approach is for the plant to live in a sub-pot that sits inside the decorative pot, such as a common nursery pot. Remove the plant/pot for waterings and to drain before returning it to the decorative pot. Dried moss is a popular way to blend the surface, making the two pots appear cohesive.
Alternatively, pebbles, stones or pumace can be layered at the bottom of the pot as a buffer to protect roots from sitting in stagnate water. Plants can be happily raised in these conditions, however one must be diligent and adaptive with their watering.
In love with a drain-free pot but not up for particular maintenance? Lot's of people make their own holes. A diamond bit can be used for ceramic pots; concrete bit for concrete and various bits for composite and other pot types.
