There are a few methods to help guide you along including:

  1. Stick your finger into the soil about a quarter of an inch or so to see how dry it is under the soils surface. This will vary slightly depending on the soil mix and amount of soil, however it is a good guide.
  2. Some will stick a chopstick or similar implement into the soil to test the dryness
  3. Another method is to check the weight of the plant by picking it up. If it is dry it will weigh less than a fully watered plant.

10. How to train bonsai trees?

There are a number of techniques developed that are used to create and maintain, i.e. “train” a bonsais tree’s unique shape and size. The two most widely used being pruning and wiring.

Pruning, a technique repeated periodically on your bonsai using small sharp scissors or pruners that are able to remove unwanted leaves, buds and branches with the aim to control the development of the bonsai’s style and shape. Two key types of pruning are:

  1. Branch pruning – used to establish the basic shape of the tree
  2. Leaf and shoot pruning – refine and improve the shape of your tree

Wiring, like pruning is an essential technique used to shape and style a bonsai tree. Wire can be used when you want to change, bend or reposition the angle of a branch. Copper or aluminum wire should be used as other metals are not suitable. It usually takes a period of 6 to 18 months before the wired branches are set to their new shape, after which the wire can be removed.
