Any type of pressure sprayer can be used but a 2 litre hand sprayer like the one shown is quite a good size for a normal garden collection of bonsai.
After spraying the tree then water should be sprayed over the soil to dilute / wash any over-spray. The pot should also be washed because if any of the diluted lime sulphur dries on the pot then it will leave a white residue mark for quite some time.
It will be seen in the photos below that a plastic sheet has been laid out on the ground, and this is a good idea as any lime sulphur drips can easily be wiped off, and it will not stain the paving. |
