General note on pesticides

Most pesticides are toxic and dangerous. Read the labels carefully and store in a safe place. Do not store for an indefinite period of time, most chemicals have a useful shelf-life, some pesticides oxidize or change after exposure to air or when mixed with water. Pesticides can be dangerous. Do not spray indoors or inhale. As some pesticides are absorbed through the skin, take due care.

There is constant development in pesticides and for this reason recommendations become dated, so always seek the latest information. Several pesticide reveal problems after some years of their introduction causing them to be withdrawn from the market, similarly, new safer ones become available.

Certain pesticides may cause bonsai to defoliate, for this reason they are generally tested before being recommended. It is important to spray on a still day and not in the full sun. Trees should be well watered before spraying. Rain or watering after spraying will wash pesticides off the sprayed bonsai, therefore a wetting agent should be used.

Random Bonsai Tip

Mixing growing medium - To mix your growing medium, put the mixture into an empty compost bag (as much as you can handle) and tip the bag backwards and forwards - this is much easier and more effective than mixing in a wheelbarrow!
