What type of Bonsai pots should I be considering?
Firstly, if you have a juvenile Bonsai that is still growing quite rapidly you will need to consider several training pots before you decide on a final show pot to exhibit your Bonsai. However, when selecting a Bonsai pot you should never pick one that means you will need to drastically trim the roots. If you do want to reduce the size of your pot or the roots then you need to take it in gradual steps, moving down a pot size at a time before eventually reaching the size you want.
Make sure the pot you are considering has very good drainage and is entirely frost proof, this will help keep your Bonsai safe and healthy all year round whether it is kept indoors or outdoors. If you are selecting a glazed pot, be sure that only the outside of the pot is actually glazed, because the Bonsai will need the rough surface on the inside for the roots to grab onto and establish themselves.
What pot for what tree?
The type of pot you should buy is indicated by the kind of tree you are growing as well as the style you want. Conifers lend themselves brilliantly to naturally coloured, unglazed pots whereas deciduous trees look good in glazed or unglazed and in just about any colours. Experiment a little to find the right pot for you, and especially consider pastel colours for your deciduous trees or a bright coloured pot for a flowering tree.
Also, consider how much room the roots will need for your particular choice of tree. Cascading trees will require a deep pot with plenty of room for the roots to grow down but also so the branches can hang over the side without draping on the floor.
If you have a heavily glazed pot, remember that the colour of the glaze will age and ware off slightly over it’s lifetime and many people wipe the glaze with French polish in order to speed the process up giving your glazed pot a slightly more natural and aged feel.
